how to log out another user without logging in – updated

Screen Shot 2016-04-30 at 20.35.31

Posted: 10th May, 2013

If you have multiple accounts on your mac, you may sometimes wish to log out one or more of those accounts without actually having to sign in to them first via the fast user switching menu. There’s a couple of ways to do this. First, if the issue is just that you want to shutdown the computer, you can log out all users by entering an Admin user name and password when this dialogue automatically appears after hitting ‘Shutdown’ (it won’t appear if no other users are logged on):

log out window

However, there are times when you may just want a quick way to log out users without shutting down and without wasting time logging in to their accounts first. Be aware that in killing a user’s process without logging in to the account first, any data in that user’s account that is not already saved (or autosaved) will be lost. If you’re sure that’s not a problem, then follow this short procedure manually or use the AppleScript version that follows:

1. Open up Activity Monitor (/Applications/Utilities/Activity Monitor.app)

2. Use the drop down menu in the Task bar to change the menu to ‘Other User Processes’  (note: you can use ‘All Processes’ in the menu if you wish, but that is less safe as it makes it possible to accidentally click on your own user process in step 4 below!).

3. In the filter bar, type loginwindow.

activity monitor

4. From the list of users that show up, for each one that you wish to log out:

  • click on its row in the Activity Monitor pane to highlight the process
  • press the ‘Quit Process’ icon in the Task bar above
  • from the resulting dialogue window, click ‘Force Quit’
  • supply an Admin password if requested.

Repeat for any further accounts that you wish to quit. (Tip: If you want to kill the ‘Guest User Account’, you’ll need to switch back to ‘All Processes’ and kill the loginwindow assigned to the ‘root’ user).

And that’s it. Your unwanted users are now logged out! 🙂

Update 30th April, 2016: If you get tired of doing this manually, you can log out all other real users at once with this AppleScript:

set thisUser to do shell script "whoami"
set usrList to paragraphs of (do shell script "ps caux -o args | grep loginwindow")

repeat with i from 1 to number of items in usrList
set this_item to item i of usrList
set thatUser to word 1 of this_item
if thisUser is not equal to thatUser then
set theProcessNum to word 2 of this_item
do shell script "kill -9 " & theProcessNum with administrator privileges
end if
end repeat

news: DetectX for Snow Leopard update released

We’ve just released DetectX for Snow Leopard v2.1 (DetectXSL), a long-awaited update that fixes, among other things, the bug in the updater mechanism.

If you have problems either downloading or installing the update from within DetectXSL*, please delete the DetectXSL.app (v2.0) from your mac and download and install v2.1 directly from here (direct download).

Now that we’ve got a working install of 10.6.8 again in the Sqwarq office, we’re planning on updating DetectXSL a bit more frequently, though working in Xcode 3 again is proving to be a bit of a memory challenge!

(and for you more up-to-date folks, don’t forget DetectX runs on everything from OSX 10.7 thru 10.11).

🙂

*requires 10.6.8, Intel, 64-bit architecture

FastTasks version 1.18 released! 💥

FastTasks v.118

I’ve just posted an incremental update to my free system utility, FastTasks. The update fixes a bottleneck in the launch code that caused FastTasks to take excessively long to load. I’ve also added the System Uptime, which you can also refresh with the new keyboard shortcut, ‘command-U’.

FastTasks saves you having to role up your sleeves and get mired in the exotic world of Terminal’s command line for a number of common tasks. FastTasks v1.18 offers you system info down the left side of the panel, all of which can be updated by the shortcuts displayed on the panel, and access to some common Terminal commands on the right.

If you haven’t tried FastTasks yet (or got tired of the slow launch times with the old version), this is a great time to grab a free copy of v1.18 as I’ll soon be replacing the app by FastTasks 2.0, a paid-for app with a whole new interface and extra functions. Nevertheless, support for FastTasks 1 will continue and bug fixes will still be forthcoming as necessary. Grab it while you can, folks! 🙂

Download FastTasks v1.18 from here…

Note: FastTasks requires OS X 10.6.8 or higher


Carbon Copy Cloner: see last back up date

CCC Last Backup Service

If you’re a user of Bombich Software’s excellent Carbon Copy Cloner but you’re not doing backups as scheduled tasks, you may wish there was a way to find out the last time you successfully completed a backup task.

Unfortunately, CCC doesn’t provide an easy way for users to see this information natively, but in this post we’re going to add it through a bit of AppleScript and Automator magic.

As it turns out, CCC does keep a log of all your past backup details stashed away in a CCC.log file buried in your local domain’s Library folder. You can view this file in Console, but it’s a bit of a pain. Wouldn’t it be nicer if you could just hit a hotkey like ‘Command-Control-C’, say (you know, for ‘CCC’ 🙂 ), and get a dialog box like this:

CCC Last Backup date
If you think so too, then download my Automator workflow:

For Lion, Mountain Lion and Mavericks:
Download for 10.7.5 thru 10.9.2 📀

For Snow Leopard:
Download for 10.6.8 💿

Double-click on the .zip file and double click again on the unzipped workflow file. You’ll get a warning message saying that you’ve downloaded the file from the internet (from me, actually!). After clicking ‘Open’ to dismiss the warning, for all users except 10.6, click ‘Install’ on the the following dialog box:

Install workflow

After clicking ‘Install’, click ‘Done’ to dismiss the confirmation dialog box that pops up.

For those of you running Snow Leopard (10.6.8), after clicking ‘Open’ the workflow should open in Automator. Hit ‘command-S’ to save it as a Service.

For all users, if you now click up to any application name next to the  Apple near the top left of your screen (see the screenshot at the top of this post) and scroll down to ‘Services’ you should see the new Service already there. If you don’t, try logging out and logging back in to your user account.

Once you can see the workflow in the Services menu, go ahead and give it a click to test it out. 🙂

A couple of notes on usage:

Carbon Copy Cloner does not have to be open for the Service to work.

The date format display is YYYY-MM-DD.

If you want to add a shortcut key as suggested earlier, open up System Preferences > Keyboard and click the ‘Shortcuts’ tab. Down the sidebar you should see ‘Services’. Click on that and scroll way down to the bottom till you see the name of the Service. Click ‘Add Shortcut’ and hit the keys you want to use. I like ‘command-control-C’ as it’s an easy mnemonic for ‘Carbon-Copy-Cloner’.

enable TRIM with FastTasks v1.17

FastTasks updated to version 1.17

Update: how to enable TRIM (for Yosemite 10.10.4+)


FastTasks has been updated to version 1.17 to support users who have installed their own SSD drives.

FastTasks now makes it simple to check the current TRIM status of your disk, and to either enable or disable it with a simple click, particularly useful if you find that TRIM has been turned off by an OS X software update or upgrade.

Note that you need to restart your mac after using the radio buttons to change the TRIM status in order to complete the process.

FastTasks – free download

FastTasks dog opened


I’ve been planning this ever since I first wrote a shell script along the same lines. All it needed was a nice interface, and that’d be something I could use almost everyday. Well, it only took me 8 months to get round to it, but here it is. 😉

FastTasks main window

Download FastTasks»

FastTasks allows you to achieve a number of things that you would normally have to roll up your sleeves and do in Terminal or AppleScript.

The window consists of two columns: left-side for info, right-side for actions. Here’s a detailed breakdown of functions with possible uses.

–Left-side (Info):
OS X Version:
Displays your current OS Version and build number

Startup Disk:
Displays your boot volume
I sometimes forget which particular volume I’m booted into, so this is vital info for me and anyone who’s regularly booting in and out of different installations.

Router IP:
The IP address of your network router
This can be useful for troubleshooting or if you need to access your router’s Admin page.
Just select the address and paste it into Safari’s search bar.

Local IP:
Your node on the local network
Useful to copy and paste if you need your local IP/ network node.

External IP:
How the rest of the world sees you
Very useful if you’re using proxies and want to check whether they’re working.

Installed Ram:
Just a courtesy reminder, but the real value here is the summary of usage stats underneath. These are pretty good approximations to what AM shows on my 10.8, but there are discrepencies on some versions of OS X between what ‘top’ shows and what Activity Monitor shows. FastTasks uses the same information that you’d get if you used the ‘top’ command in Terminal.

By the way, there’s a refresh button (keyboard shortcuts shown) for both the memory usage and network addresses, as the displays do NOT update continuously. Using the refresh buttons does not CHANGE anything on your system: They just update the display to reflect the current state of the system.

–Right-side (Actions):
Show hidden files:
Reveal or hide the hidden files and folders in the Finder whose names begin with a period
This is probably the most useful function of the app as it provides a dead easy way to hide and unhide system files without messing around in Terminal.

Show User Library:
Reveal or hide the User Library in the Finder
Likewise, this hides or unhides the ~/Library folder in Finder. This is ‘hidden’ in a different way from files that begin with a period, and its setting can be manipulated independently of that setting, so you can have the User Library showing, but ‘hidden’ files still hidden.

Flush DNS Cache:
Flush the cache that resolves internet domain names into IP addresses
Flushing the DNS cache can sometimes help resolve problems when you can’t access certain websites. Depending on what system you’re running, you may or may not see a ‘Requires Admin password’ warning next to this button. If you see the warning, then when you press the button the system will ask you for your password. The password request is from OS X and it goes to OS X: It’s not called, seen or stored by the app itself.

Free Memory:
Purge the RAM of inactive memory
Again, depending on what system you’re running, you may or may not see a ‘Requires Admin password’ message. On Snow Leopard, this requires the Command Line Tools supplied with Xcode, so if you see a message telling you to install Xcode, you may have to live without it (availability of Xcode for Snow Leopard these days is a bit hit and miss). You’ll also see the information on the left-side refreshed under ‘Usage’ when you use the free memory function and it successfully completes.

NOTE: on some systems where both Flush DNS Cache and Free Memory display ‘Requires Admin password’, note that after supplying the password for one of those actions, the user will be able to perform the other action without authenticating for a period of around 5 minutes (unless the sudo timeout setting has been altered by an Admin user).

Lastly, at the bottom of the window you’ll see a tiny plea to donate if you find the app useful ;). Note that the underlined text ‘Applehelpwriter’ and ‘Donate’ are hotlinks that if clicked will launch Safari and load a tab with this site and a Paypal donate page, respectively.

I hope you enjoy using FastTasks. Please read the provided Licence and User Guide that are in the download. Thanks! 🙂

Automator: make your own icons

Automator in action

Back around Christmas I posted this little procedure for making your own icons, with the promise that sometime I’d get round to writing it up as a script. Well, reader Cameron Leask has saved us all the effort and created this great little Automator workflow to do just that!

Download the workflow by clicking on the Automator robot below. When the download’s finished (it’s only 2MB), save it in your Applications folder.

To use it, just click on it to run. The first time you do that you may need to override your GateKeeper settings. Once you’ve allowed the app permission to run, choose the image you want to make into an icon and click ‘OK’ or press ‘return’. Cameron’s workflow will do the rest.

After a few seconds, you should see a little confirmation dialog telling you the icon is on your Desktop. Be sure to change the name of your new icon and/or move it to somewhere else before running the workflow again (or the next icon you create will overwrite the previous one).

Click the Automator robot to download:

Automator_Icon








Picture to icon.app

Thanks a million Cameron!

Got your own favourite Automator workflow or AppleScript you’d like to share? I’d be happy to consider posting them on Applehelpwriter. Just drop me a mail.

how to see recently accessed files

speed


While professional troubleshooters will use software like fseventer or the Instruments.app that comes as part of Xcode, there’s an easy way for anyone to see which files have recently been accessed on their Mac.

1. Open any Finder window and hit ‘command-F’.

2. Click the ‘Kind’ button and choose ‘Other’ at the bottom of the menu:

Finder Search menu: Other

3. Next, scroll down the list till you see ‘System files’ and check the box and hit ‘OK’.

4. Change the button that says ‘aren’t included’ to ‘are included’.

5. Now hit the little ‘+’ button over on the right side of the window.

6. Again, change ‘Kind’, this time to ‘Last Modified’ and change ‘within last’ to ‘today’.

search

7. Finally, go to Finder > View menu at the top and choose ‘Arrange By > Date Last Opened’.

You can save the search in the Sidebar for convenience. Give it a more useful name like ‘latest changes’ or ‘fs events’ (“fs” stands for filesystem) and click on it whenever you need to check what’s just happened to your Mac! 🙂

how to check what’s been installed on your mac

Rectangleum by *Eccoton


UPDATE: I’ve written a free app that pretty much supercedes what I wrote in this post. DetectX 2 now has a system analyser that records and displays changes to your system configuration over time.

Ever wondered if a link you clicked sneakily downloaded and installed some unwanted software on your mac? Or have you suddenly found your mac behaving weirdly, a situation that is often a result of installing new software that conflicts with something else on the system, but can’t remember what you recently installed? In these sorts of scenarios, what you need to do is check your install logs.

I’ll tell you how to do that in a moment – in a number of ways – but first let’s just make a few notes. Firstly, chances are you’ll find more than one install log in your logs folder. The most recent one is simply called install.log, older ones will have a filename ending with .bz2, indicating a compressed file. Secondly, the reason you may have more than one install log is that OS X creates new install logs every time the log file gets to around 1MB in size. It then compresses and keeps the old logs, typically up to five logs prior to the current one.

Pro Tip No.1: if you’re a Terminal whizz and you want to change how many old logs are kept or at what size the log file gets turned over, you can edit the /etc/newsyslog.conf file, but be sure to read the man page for newsyslog first.

Typically, we’re only going to be interested in examining the most recent log file if troubleshooting new problems, but the process that I’m going to describe here can also be used to view the older logs, too. Apple buries the logs deep into parts of OS X that ordinary users typically don’t reach, but fortunately, there’s numerous ways to get at your install logs, and though some of them may be unfamiliar, none of them are particularly difficult or dangerous.

1. View only recently installed items
Open the Terminal.app (Utilities/Terminal.app) and copy and paste this command:

grep 'Installed' /private/var/log/install.log

This will return a list of every item successfully installed since the new log file was created. If there’s nothing of interest there, but you think there should be, then you’re going to need to see a bit more of the log file, and perhaps find out when it was ‘rotated’ or ‘turned over’ (i.e., the last time the system archived the install.log and created a new one).

2. View the entire install log
If you’d like to see the whole log for this reason, or perhaps you want to see whether something failed to install, it’s probably best having the log displayed in TextEdit rather than Terminal, so copy and paste this command into the Terminal window:

cat /private/var/log/install.log | open -f

You’ll see at the beginning of the file it’ll tell you when the file was turned over. Don’t forget you can use TextEdit’s search facility (Command-F) to search for particular instances or items you’re interested in finding. When you’re finished viewing this file, you can simply close TextEdit and discard it. It isn’t the actual log file, but rather a local copy of it.

3. Using Console
Alternatively,, if you don’t feel comfortable in Terminal, you can view all your install logs in the Console.app. You can open Console either through Finder by navigating to /Applications/Utilities/Console.app or just by typing ‘cons’ in either Spotlight or Launchpad. Once Console is open, scroll down the sidebar, looking for /var/log. Click the disclosure triangle if it’s not already pointing downwards and look for install.log. Click on that, and then in the filter bar in the main window, type installed (unlike the grep command I gave you above, this one is not case sensitive and will return both ‘Installed’ and ‘installed’).

examining an old, compressed install log

Notice in the screenshot above, I’m examining a turned over log, not the current one. As this particular install of Mountain Lion was only done on May 3rd, there’s only one turned over log file.

Pro Tip No.2: You can force the system to turn over all the log files, including install.log even if they haven’t reached their maximum size. As it says in the man page for newsyslog, this can be “useful for diagnosing system problems by providing you with fresh logs that contain only the problems.”

To force all log files to be turned over, simply enter sudo newsyslog -F into Terminal. Hit ‘return’ and supply your password, as always with the sudo command.


4. Using Finder
If Console is a bit too off-territory for you, there’s nothing wrong with viewing your logs in Finder and TextEdit. To do that, click on the Finder, then hit ‘shift-command-G’ on the keyboard (or click ‘Go’ in the menu bar and choose ‘Go to Folder’). Type or paste this into the dialogue box:

/var/log

and hit the ‘Go’ button.

Go to folder

Right-click on any of the logs you want to open and choose ‘open with’ from the contextual menu. Choose ‘TextEdit’ or your favourite plain text editor app. If none of your text editors show up in the menu, click ‘Other’ and change the ‘Enable’ menu to ‘All Applications’. You will now be able to choose TextEdit or some other editor if you have one. Note that unlike Step 2 above when we used a Terminal command to open a copy of the install log in TextEdit, here you are viewing the actual files rather than a copy of them. Although the log files are not important to the running of your system and can be deleted or altered without causing any consequences, they do provide useful records for troubleshooting so its always good practice to keep them in tact if you can.

And that, in a nutshell, is how you view your install logs! 🙂
