Ever called up a HelpViewer window in an app only to find that you have to close the window in order to get back to the app and start following the instructions? That can be highly annoying if the instructions aren’t easy to remember.
That’s because the HelpViewer.app is by default set to always be on top. If you want to change that, here’s a nice little Terminal trick that will let you manage HelpViewer windows just like a normal window, courtesy of new tipster site defaults-write.com. Here’s what you do:
1. If you have any HelpViewer windows open, close them first.
2. Open Terminal.app (/Applications/Utilities/Terminal.app) and paste this command into the window:
defaults write com.apple.helpviewer DevMode -bool true
and press ‘return’ on your keyboard.
That’s it! From now on, you’ll be able to switch focus between the app and the HelpViewer window so that you can work with whichever one you need on top.
Tip: If you want to reverse the behaviour, use the same command as above but replace ‘true’ at the end with ‘false’.
If you like exploring the various things you can do with defaults preferences, have a rummage around the defaults-write.com site, a nice little addition to our bookmarks list!
Whenever I’m helping customers with a misbehaving Mac, one of the most common things I hear is ‘Wow, I didn’t know you could do that with Spotlight!’ Whereas the average user will navigate around their computer by trawling through Finder, the savvy user knows how to get to places, launch apps, search the internet and calculate their tax with a few simple Spotlight tricks. In this post we’ll look at how to increase your productivity by using Spotlight for fast access to a variety of common functions. But first, we need to get Spotlight set up for maximum efficiency.
Set up the hotkey
To get the most out of Spotlight, the first thing to do is set up the keyboard hotkey. By default, this is usually ‘command-spacebar’, but if you are using multiple languages you might want to reserve that for the Input Switcher. Instead, I use ‘option-command-spacebar’, not least because this nice 3-finger combination can be executed with the left-hand while the right hand is reaching for the coffee mug…😉
Whatever your choice of hotkey, keep it close to the bottom of the keyboard, as the other keys that you will want to be able to rapidly access are the cursor arrows and the ‘return’ key. If you haven’t set up your Spotlight hotkey yet, the fastest way to do so is to click on Spotlight on the top right of your screen with the mouse or trackpad and type
After hitting ‘return’, you’ll be presented with the Spotlight preferences panel. At the bottom, you’ll see fields to define both the Spotlight menu keyboard shortcut and the Spotlight window keyboard shortcut. For the purposes of this post, we’re only interested in the menu shortcut (but feel free to set up the window one too, if you wish!). Once your hotkey is set up you can forget about the annoying inconvenience of dragging your cursor up to the top right corner. Just hit your hotkey combination to open the Spotlight search field.
But don't close the Spotlight prefs just yet. The main pane in the window is the Search Results panel which lists the order in which results appear. You can alter the order of results that Spotlight shows by dragging items up and down the list. Altering this to your likes is a big part of getting the most out of Spotlight. If Spotlight is always showing you lots of results from Mail that you don't want to see, for example, drag "Messages & Chats" to the bottom of the list.
For the purposes of this tip, make sure Applications is no.1 in the list and System Prefs no. 2, and Folders at no. 3. Follow that with Documents, Images, PDFs and so on according to the kind of files you access most often on a daily basis. A set up like this will make Spotlight much more efficient at navigating around your mac, and once you get the hang of it you’ll find yourself trawling through Finder much less often.
Incidentally, I don't recommend unchecking any of those boxes. We want more power in our searches, not less; you never know when you might be looking for something that just won’t show up in a search because you’ve forgotten that you excluded those results in Spotlight’s preferences. Besides, there are better ways to restrict your searches in Spotlight like this and this.
When you're done with setting up Spotlight’s preferences, hit 'command' and 'Q' to close System Preferences and read on.
1. Use Spotlight as an App Launcher
Long before the Apple engineers dreamed up Launchpad, many of us were already launching apps in half the time it takes in the Dock, Finder, or (now) even Launchpad itself. You can open any app with Spotlight just by typing three or four characters. Sometimes, just one is enough! All you need to do is hit your hotkey (see above) and type the first three or four letters of the App’s name and hit ‘return’.
tex and hitting ‘return’ to instantly open TextEdit, or
act for ‘Activity Monitor’. iPhoto should be the top hit with
ip. If you use Terminal a lot, there’s no need to go rooting around in the Applications/Utilities menu to open it. Simply hit the Spotlight hotkey and type
and hit ‘return’.
If you have Carbon Copy Cloner, type
CCC, and if you use 1Password, just the number
1 and return should do the trick.
saf will open Safari and
mai will launch Mail in an instant. Experiment with your favourite or most commonly used apps and you’ll find that using Spotlight is twice as fast as any other method.
As a bonus, if you moved Folders up to no.3 in the Preferences list, experiment with the first few letters of your favourite folders. Try some of these and see what comes up as the top hit:
2. Use Spotlight to access System Prefs
We already saw one of Spotlight’s hidden uses – fast access to System Preferences. In fact you can do this with any of them. Want to check your login items in Users & Accounts | Login Items? No need to go clicking all round the desktop, hit your Spotlight hotkey and type
if you want to change your Security preferences quickly.
Don’t hit ‘return’ just yet – check to see what is the ‘top hit’, as you might find that you have to “arrow down” an item or two. Even so, this is a whole lot faster than wading through either Finder or the menu.
and hitting ‘return’ is also a fast way to open the main System Preferences panel.
Hit the Spotlight hotkey and try typing the word
Just press ‘command-L’ to go straight to the dictionary entry and see its definition in a pop-up panel. Alternatively, hit ‘command-D’ to open the word in the Dictionary app.
Also note that in Spotlight, you can jump around by holding down the ‘command’ key and pressing the down arrow key (each press of the arrow key conveniently takes you to the top of each section; release the ‘command’ key and use the down arrow alone to move one item at a time within the section). Using the ‘control’ key and the down or up arrow takes you to the very bottom or the very top of the list, respectively.
When you’re done with Spotlight, just hit your hotkey combination again to dismiss it. You can also use the ‘esc’ key here: one tap of ‘esc’ will clear the Spotlight search bar, two will dismiss it.
4. Website search
But suppose you type in a word that Dictionary.app doesn’t know? Try
Again, use your command and arrow key to jump down to the bottom of the results and this time choose ‘search the web’. That will automatically open Safari and put the term in the search bar and return the results. But you’re not limited to dictionary searches, you can use Spotlight’s search bar just like the Google search bar in Safari. Try typing in
mini ipad versus samsung galaxy review
best small car of 2012
or anything else you might want to search the web for. Yep, Spotlight isn’t just a file finder on your mac – it’s a google search engine, too!
5. Use Spotlight as a Calculator
Want to quickly know what 17.5% of $45,000 is? Hit your Spotlight hotkey and type:
Don’t press ‘return’ – difficult to break that habit, I know! – the result is already listed next to the ‘Calculator’ icon, just look down to see the search results and the answer is already there!
You can of course do all the standard calculator functions like / for divide, * for multiplication and + and – for addition and subtraction. You can even do powers (3 to the power of 5 = 3^5) as well as bracket expansion. Try
(3x5)^2 and compare the result with
So whether its App launching, web searching, opening system prefs or using the dictionary or calculator, hitting your Spotlight hotkey is a habit you want to develop for faster computing. At least for me, it’s probably the most frequent keystroke I use on a daily basis.
I’ve been a long time user of TechSmith’s Camtasia screen capture software, primarily for two reasons: ease of use combined with a rich set of editing features. Camtasia for Mac 2 strengthens this product in a number of significant ways although there are still some usability issues that need addressing, as well as room for further improvements in the feature set. In this review, I’ll walk you through what Camtasia has to offer as well as indicate the kind of uses where it excels as an aid to the technical communicator. Read the review…
If you see a screen with a progress bar (something like the shot above), your Mac is starting up in Safe Mode. This shouldn’t happen unless the user intentionally wants to do so for troubleshooting purposes. However, if you find that your Mac is defaulting to Safe Mode when you try to start up normally, try the following tips.
1. Stuck Shift key
Check that the Shift key is not accidentally being pressed down or stuck. If you suspect the keyboard may be faulty, plug in a different keyboard.
2. Use Terminal to reset boot-args
Allow the machine to finish booting into Safe Mode, then open Terminal (Applications/Utilities/Terminal.app) and copy this command into the Terminal window:
sudo nvram boot-args=""
press ‘return’ on your keyboard. Enter an Admin password (type carefully as it will not be echoed to the screen) and restart the Mac.
3. Do a PRAM reset.
In this case, a PRAM reset effectively does the same as No.2 above. However, if No.2 didn’t work, it’s worth trying this way of doing it in case for some reason the boot memory failed to hold the preference setting. You can also do this step instead of Step 2 if you are not comfortable with using the Terminal.
The PRAM reset is done like this:
1. Power down the machine.
2. Locate the following keys on your keyboard in preparation for Step 4:
3. Press the ‘power on’ button.
4. Immediately – and before the grey screen appears – hold down ‘command-option-P-R’ all together.
5. Keep them held down until you’ve heard the start-up chime twice. After you release them you should hear it again, and hopefully your Mac will boot up as it should normally.
If you need to flush the DNS cache in Mac OS X, be aware that the commands for this have changed through successive OSs, including Lion.
Flushing the cache is sometimes a good idea if you are unable to reach a site that you know is live but keeps returning an error (you can check whether a site is live for others by typing its address here: Down for everyone or just me?).
You can download my free app FastTasks that will do this (and a whole lot more! ) for you without you needing to mess around on the command line. However, if you want to do it manually, then open Terminal (Applications > Utilities > Terminal.app) and use the appropriate command for your operating system:
In Leopard / Snow Leopard
In Lion and Mountain Lion
sudo killall -HUP mDNSResponder
With Lion, you’ll have to follow the command with your Admin password, which will be invisible when you type it.
FastTasks – a utility for common terminal tasks
In the last post, we learned how to see all the contents of a folder – invisible and visible files – in the Terminal. However, most of us prefer working in the GUI, so this post is going to show you how to work a bit of Terminal magic to easily turn on and off your invisible files and folders in Finder and the desktop.
Open Terminal, and type or copy/paste the following to the command prompt:
defaults write com.apple.finder AppleShowAllFiles TRUE; killall Finder
(note that all commands in these posts should always be assumed to be case-sensitive).
Now switch out of Terminal and have a look at Finder or your desktop. You should see some ‘hidden’ files now in a sort of greyed-out 50% opacity (files like .DS_Store). If you can’t see such files, go back and check that you typed or copied the entire command correctly.
Assuming you can now see your invisible files in Finder, switch back to Terminal. Press the up arrow key on your keyboard. Notice that the last command you typed reappears.
That’s a handy trick to remember. You can move between your previous commands with the up arrow and down arrow keys to save time re-typing or modifying commands.
In this case, we want to use the last command again, but we also want to modify it. Use the left arrow key to move the cursor back to “True” and then use delete to remove “True”. Leave the cursor where the letter ‘T” was and type FALSE. Make sure the semi-colon ; is still there.
Press Return — you don’t need to move the cursor to the end of the line as you would with a word processor. You can hit Return no matter where the cursor is in the command line and it will execute (or try to) whatever is typed on the whole of the command line.
Now, if you switch back to Finder or the desktop, you should see that all your hidden files have disappeared again.
OK, now that we have tested these commands to check that they work, let’s do something a bit more useful with them.
Switch back to Terminal. Type
and press Return.
Wow! Did you see what just happened? You substituted the word “FALSE” from the last command with the word “TRUE” and executed the entire command. In other words, you just made your hidden files visible again! Go and look at the desktop and you’ll see that your invisible files just returned. Try it again. Switch back to Finder and type
to replace the word “TRUE” in the last command with the word “FALSE”. Hit Return to execute it.
Using the pattern ^error^correction is a great way to both correct commands you type incorrectly and to run two commands one after the other that have only one term or option different.
Back in Terminal, hit the up arrow to bring the last command back onto the command line. This time, I want you to hit control-A on your keyboard. Notice that this brings the cursor to the start of the command line, which is what we want as we’re going to type in a new command before the “defaults…” part.
With the cursor at the beginning of the line, type
and a space. Then type a double quotation mark right next to the ‘d’ of ‘defaults, so the beginning part looks like this
(the ellipsis or ‘…’ is used here just to show that the command continues and should not be in your actual command line)
On the keyboard, press control-E.
This takes the cursor to the end of the command line (remember: control-A to go to the start, control-E to go to the end).
Type another double-quotation mark right after the word ‘Finder’ so the ending looks like this
… ; killall Finder”
Now hit the spacebar once, and type a double right angle-bracket
Hit the spacebar again and type
The entire command should look like this:
echo “defaults write com.apple.finder AppleShowAllFiles FALSE; killall Finder” >> .bash_profile
Now press Return. Type
and press Return one more time.
What did we just do?
To see what you did, type
As you can see, after testing those two commands on the command line, we’ve now sent them to the .bash_profile file, saving us the job of typing them out again (and possibly making an error when we do so). However, we can’t leave the commands like that – if we do, then they will run every time we log into the Terminal. Rather, we want to use these commands to define functions, just like we did last time with ‘show’ and ‘up’.
To do that, press control-L on the keyboard, then use the down arrow key to bring the cursor to the beginning of the first line with a ‘defaults’ command on it.
Press Return. Press the up arrow once, then type
Press Return and in the new line created type
Use the down arrow key to move the cursor down to the line below the “Defaults…FALSE” line and press Return.
In the new line created type
Then press Return. Type
Press Return and type
Use the down arrow key to move the cursor below the “Defaults…TRUE” command. (If you can’t go below the last typed line, then on the keyboard press control-E to move the cursor to the end of the line, the press Return).
Check that the whole thing looks like this:
to logout. Then press command-W and command-N to close and reopen Terminal.
What did we do this time?
We just made some new, easy-to-remember commands to show and hide our hidden files in Finder and the desktop. On the way, we learned how to append commands to files using the >> function, as well as how to move the cursor to the beginning and end of a line using ‘control-A’ and ‘control-E’ respectively. We also learned how to recall previous commands on the command line using the arrow keys and how to correct or modify previous commands using the ^error^correction pattern.
Wow, you’ve come a long way in two short tutorials!
To test out what you just did, type
then press Return.
Switch to Finder and there’s all your hidden files! To make them invisible again, switch back to Terminal and type
From now on, whenever you want to see your hidden files, just use the show_all command in Terminal. Hide them again with hide_all.😀
control-A – places the cursor at the beginning of the command line (also works in emacs editor)
control-E – places the cursor at the end of the command line (also works in emacs editor)
control-L – on the command line, this clears the screen (equivalent to the ‘clear’ command); in emacs, this places the caret inside the editor allowing you to edit (=insert point)
up & down keyboard arrows – moves through history of commands
^error^correction – replaces the term after the first ^ with the term given after the second ^ in the previous command, then executes the entire command
echo – sends the following string or command to the specified file (if no file is specified, the string will output back to your terminal screen. In other words, if you type echo hello, the Terminal will print “Hello” on the next line; hence the term ‘echo’! )
This is the first in a series of planned tutorials for anyone who wants to find out what Terminal can do and how they can use it to increase the usability of their computer. Unlike other Terminal tutorials, I’m going to assume that you’re not interested in giving up the desktop for the command line to do things like move and copy files that you can do more easily in Finder. Rather, I’m only going to focus on those things that it’s generally more difficult (or impossible!) to do in the GUI than it is in Terminal.
Let’s get started. Open Spotlight (try the hotkey command + spacebar or click the spy glass in the top right corner) , then type term and press Return.
When Terminal opens, the first thing you may want to do is make the text a bit easier to see in the Terminal window.
Hold down command-shift-+ to increase the size. Try it a couple of times till the text is a comfortable size. If you overshoot, just use command- – (minus key) to reduce text size.
Now you’re sitting comfortably in your Terminal window, let’s learn our first spell. Actually, we’re not going to learn one so much as make our own!
In order to do that, we want to open a hidden file and edit it. In Terminal, type
(There’s a space after ’emacs’, and, don’t forget that . dot right before the ‘b’)
What you see after this screen may vary depending on whether .bash_profile has any pre-existing content or not. If there is anything in the file already, ignore it and use the arrow key to move the cursor to a clean line at the bottom. If the file is empty, then just start typing. The first line we want to type is
Now press Return and enter a single, left curly bracket
Press Return again and type (or copy and paste) this:
There’s a space between the ‘s’ and the dash, and all the letters are lowercase except the ‘F’, which must be uppercase.
Press Return and provide the closing curly bracket
It should look like the area inside the orange rectangle:
Now hold down the control key on your keyboard while you first press x and then c. Notice at the bottom of the screen you get a ‘save’ warning.
Press the y key on your keyboard, and you should find yourself returned back to the Terminal prompt.
Type exit at the prompt to logout of the Terminal, and then on the keyboard press Command-W to close the window, and Command-N to open a new Terminal session.
What did we just do?
We defined and saved a new Terminal command called show which we can now use whenever we enter Terminal to easily see all the files and folders – including all the hidden ones – in any given directory. To see what we just did, type show at the command line. You should get an output that is formatted something like this:
As you can see I’ve annotated the screenshot to show some of the features that the show command gives us. First of all, notice the file and folder names that begin with a . dot. These are your hidden files and folders (Remember: they are usually hidden for a reason, so don’t go messing with them unless you know what you’re doing!). The show command also helps us distinguish between files and folders by appending a / slash to the end of folder names. Although not shown here, you may also see some names with an * at the end. That means it’s an executable file — in other words, its purpose is to run some programme or command.
The show command is very useful for seeing exactly what is in a folder, but of course we need to know how to move between folders in order to see anything other than our own home directory.
Suppose I want to have a look in that folder called ‘Shared’. Then what I do is I type
then press the tab key on the keyboard. The rest of the name is filled in for me by Terminal:
The tab key is a very useful trick for moving around in Terminal when you are faced with long names. Generally, you only have to type in enough to make the file or folder name unique and hitting tab will complete the rest of the name for you. However, if I only type
and then press tab, nothing happens. Terminal can’t complete the name because there’s more than one choice. However, if I press tab again, Terminal will give me a list of the all names that begin with S:
pressing tab twice gives:
Now I can see all the options, and how much I have to type to make a unique choice. In this case, I only have to type either ‘cd Sh’ or ‘cd Sn’ to allow Terminal to know which one I want when I press the tab key. Pressing Return after the tab completion will take me to the folder.
Try it with a folder from your own list.
After changing to a new folder, perhaps your screen is getting a bit messy. Let’s clean it up before doing show again. On the keyboard, press control-L to get a clear screen (notice that all your previous commands and outputs are still available if you scroll up!).
Now type show again to see your files and folders, pick a folder (if there is one), and type cd plus the first few letters of the name. Fill it out with the tab key and then press Return.
Again, type show to find out what’s inside. You can keep going deeper into the directory tree by using cd and show on any folders you find.
The last thing we need to know for today is how to go back up the tree, or to move back to the parent folder. Again we’re going to use the ‘cd’ command, but this time you don’t need to type any names. Just a space and then two dots
(don’t forget there’s a space between the ‘d’ and the two dots). This will always take you to the parent folder of the folder you’re currently in, all the way up to your hard disk’s parent directory. If you want, you can make a new up command (just like we made show) as a shortcut for ‘cd ..’. Have a look at the smallest of the screenshots above and see if you can do it.
So now you know how to move around and see all the hidden and un-hidden contents of your drive, go and explore and get yourself used to these first basic commands.
When you’ve finished with your Terminal session, type exit and press Return. You can then close the window and go back to GUI land!
. at the beginning of a name means ‘hidden’
/ at the end of a name means ‘Folder’
* at the end of a name means ‘executable file’
cd – move in to that folder
cd .. – move back to the parent folder
emacs – opens the Terminal textfile editor
show – shows a complete list of a directory, including hidden files
control-L – clears the Terminal screen
tab – will try to complete file or folder names
tab (twice) – will offer choices
learning the Terminal – Part Two
If you have reverted your mac to Snow Leopard from Lion, its important that you also remove the Recovery HD, as it can compromise the security of your Snow Leopard installation (for security issues with Lion, see here). Reverting to SL via Time Machine or restoring from a clone will leave the Recovery partition in place, meaning anyone can boot into it and reset your Snow Leopard passwords merely by restarting your mac while holding down the ‘option’ key.
To remove the Recovery disk follow this procedure:
1. Revert back to Snow Leopard using Time Machine or a clone.
2. Once you’re up and running and have confirmed everything is good, go to Terminal (Applications > Utilities > Terminal) and paste/type this command to confirm the presence of the Recovery HD:
then press ‘Return’. If you see a partition labelled something like this
Apple_Boot Recovery HD (see image above)
then you will need to continue with the rest of the procedure. If the Recovery HD is not listed here, you do not have the Recovery partition and need not worry further.
3. If you find the Recovery HD in the list, paste the following command into Terminal:
defaults write com.apple.DiskUtility DUDebugMenuEnabled 1
Now open Disk Utility (Applications > Utilities > Disk Utility). In the menubar at the top, choose Debug > ‘Show every partition’
On the left in the main Disk Utility window, you’ll be able to see ‘Recovery HD’ (it’ll be greyed out). You can click ‘Mount’ in the taskbar to make it active, and you can now delete it using control-click/right click – erase or by using the ‘erase’ tab in DU’s window.
If you want to confirm that the Recovery disk is no longer present, go back to Terminal and type the command from step 2.
