unable to turn Bluetooth on or off

If Bluetooth is stuck in the on or off setting, this simple procedure should cure the problem.

You may have already tried clicking in the Status bar icon or the System Preferences pane; perhaps you even did a Restart, all without effect.

The surprisingly simple answer is:

Shutdown the mac, and power on again.

Shutdown works whereas Restart doesn’t because – unlike Restart – Shutdown puts the Bluetooth power manager through a complete power cycle.

how to remove ‘Top Sites’ in Safari

If you are fed up with the ‘Top Sites’ feature in Safari 5, here’s how to remove it.

1. In Safari > Preferences > General, change ‘New windows open with’ and ‘New tabs open with’ to either ‘Homepage’ or ‘Empty page’ (as you prefer).

2. In Safari > Preferences > Bookmarks, uncheck ‘Include Top Sites’.

Now you also need to get rid of the caches, and to stop Safari from continually storing images of your web page history (Tip: Safari will still track your History in the normal way, but here we are going to prevent it from downloading the image files that are used in Top Sites), so:

3. In Safari > Reset Safari…, check ‘Reset Top Sites’ and ‘Remove all webpage preview images’.

Click ‘Reset’.

4. Go to your home folder Library (~/Library) by clicking on the Folder icon in the dock, pressing ‘shift-command-g’, and typing ~/Library in the box.

Navigate to Caches >

5. Click once on the Cache.db file. Hit ‘command-i’ on the keyboard. In the Get Info panel that opens, check the ‘Locked’ box. Close the panel.

6. Click on the Webpage Previews folder in and press ‘command-i’. Check the ‘Locked’ box. Close the panel.

7. Navigate back to Caches > Metadata > Safari> Bookmarks. Go into the Bookmarks folder, hit ‘command-a’ and then ‘command-delete’ to send all the selected files to the Trash.

8. With the Bookmarks folder selected in Finder, press ‘command-i’ and check the ‘Locked’ box. Close the panel.

That’s it. No more ‘Top Sites’, and no more wasted time or space downloading and storing webpage previews! :- )

And what about later versions of Safari? There’s no way to remove Top Sites in Safari 7 that I know of (if you know different, please leave a comment below). However, there’s no reason to suffer in silence! Let Apple’s Safari dev team know how much you dislike it:

how to unfreeze your iPad

iPads are so easy to use, why bother with the manual? 😉 The chances are though, that at some point you’re either going to find that an app freezes on your screen or your whole tablet becomes unresponsive. Don’t panic, the answer’s simple:

First, be sure that it’s connected to a power source. The most common reason for iPads not working is people don’t realise they’re out of battery! Otherwise try these:

If it’s just a particular App that’s frozen on your screen:

— Hold down the ‘sleep/wake’ button (top right, back edge) for about 5 seconds until the slider appears. Release the ‘sleep/wake’ button. Now hold down the ‘Home’ button (bottom front, centre) until you see your Home screen.

If your whole machine is unresponsive, then do a restart:

— Hold down the ‘sleep/wake’ button for about 5 seconds until the slider appears. Slide it to ‘Off’. Then hold it down again until the Apple logo appears showing that the iPad is restarting.

If that doesn’t work, do a hard reset:

— Hold down the ‘sleep/wake’ button AND the ‘Home’ button simultaneously for about 10 seconds or until the Apple logo appears.

*For more serious problems with your iPad, such as continual restarting or no home screen, have a look here.

avoiding autosave applications

If autosave is slowing you down, there may be nothing else for it than to switch from your favourite Apple app to an alternative that doesn’t use the feature. Here’s a rundown of some of the main autosave-enabled apps and some possible non-autosave replacements.

Preview –> Skim (for pdfs)
Skim is a great little free program that is based on Preview but adds some extra functionality, especially useful if you do a lot of annotations and note-taking. All the basic controls are familiar from Preview, including trackpad zooms and rotations. There’s two limitations: it’s pdf only, and it doesn’t have the ability to create hyperlinks.

Preview –> Graphic Converter (for images)
Old standard beloved by many Mac users. Note that the latest version does support autosave, but unlike native Apple apps, gives you the option to turn it off. Available on the app store. Main drawback: it’s not free (current price about $40).

TextEdit –> Tincta
Love this free program, and you can find it in the app store. Does everything TextEdit does and more. If you do any sort of coding, you’ll love Tincta. Everyone should have this!

Terminal –> iTerm2
You’re not really going to notice autosave in Terminal if you only use it for the odd command. If you’re doing anything more than that, well, you should be using iTerm2 anyway. Free, powerful, essential.

Pages & Numbers –> Office/Libreoffice
The only real answer to these outside of the MSOffice suite is the free Libreoffice.

Keynote –> Powerpoint/OpenSong

Well, sometimes it’s just the devil you know. Yes, you can’t really beat MSPowerpoint, but of course that’s a heavy investment. A free option that might be worth giving a try is OpenSong.

Tried any of these, or found your own alternative to autosave-apps? Let us know in the Comments below!

taming Versions…sort of

If you’re working with large files in Keynote, Pages, Numbers or other Versions-supported programs, and making multiple changes at regular intervals, Versions could just be eating up your hard disk and causing a big-slow down in your work.

If you want to reclaim all that space and speed things back up, go delete the .documentrevisions-V100 folder in the root directory of your hard disk, the place where Lion stores all your document versions. Be aware that this means you will lose ALL Version history for ALL your Version-supported applications. If you are comfortable with that, read on…

You need to do four things: enable the root user, show hidden files, change the permissions on the folder and finally check the folder’s contents and delete it. Here’s how:

1. Show hidden files
In Terminal (Applications > Utilities) type

defaults write AppleShowAllFiles YES
Press ‘Return’, then type
killall Finder

2. Enable root user
Go to  > System Preferences…Users & Groups
Click ‘Login Options’
Click ‘Network Account Server: Join’
In the resulting dialogue box, ignore the text input and click the button below, ‘Open Directory Utility’
Click the padlock at the bottom of the next box and enter your admin password.
At the top menu bar of Directory Utility, choose the ‘Edit’ menu > Enable Root User
If you are requested to set a password for it, set the same one as your Admin password (this ensures you won’t forget it).
Log out through  > Log out (username), then log back in with user ‘root’ and the password you just enabled.

3. Change Permissions
Now go look in the root directory of your hard disk.
You should see a greyed out folder called ‘DocumentRevisions-V100’. If it has a ‘no entry’ icon on it, click the folder and press ‘Cmd-i’ on the keyboard (or right click the folder and choose ‘Get info’).
Scroll down to the bottom of the box, click the padlock, and enter your root password if necessary. Change all the permissions to ‘read & write’, and click on the ‘gear wheel/cog’ and choose ‘Apply to enclosed items’ if it appears.
Choose ‘OK’ in the warning dialogue box.

4. Deleting Versions history
Now you are ready to go and look inside the Versions directory. I recommend you have a nosey about and check the file sizes both of the folder itself and of the individual contents. Now, here’s a warning: you can’t just delete some of the contents in the folder. If you do, in about 24hrs Lion will see that the folder is corrupt and mark the whole thing as ‘bad’ and make a new Versions (.DocumentRevisions-V100) folder. What this means is that you will lose access to Versions in the UI, but you won’t get your disk space back as it won’t delete the ‘bad’ folder.

The only option is to either lock the thing back up and leave it alone, OR delete the entire .DocumentRevisions-V100 folder with all its contents.

Restart your computer logging in as your usual user.

Lion will make a new, empty DocumentRevisions-V100 folder to replace the one you deleted and start filling it up with versions you make from then on. You’ll have reclaimed your disk space (and removed all your previous versions), but you’ll need to keep doing the same process at regular intervals.

a. No, this does not affect your original saves or any duplicates. Only the versions.

b. Messing about as a root user can have serious consequences if you mess with other stuff. Do as the instructions say and nothing else unless you know what you’re doing. After you’ve deleted the Versions folder and emptied the Trash, go back to Directory Utility > Edit and disable the root user.

c. To stop seeing the hidden files, type the same command as given in 1. above into Terminal, but change ‘YES’ to ‘NO’. Don’t forget to do the ‘killall’ command afterwards.

d. If you have trouble saving documents without re-booting after deleting .DocumentRevisions-V100, try this script from Apple Discussions user Yvan. This will recreate a clean (i.e., empty) Versions folder every time you reboot, saving you the hassle of regularly cleaning out the .DocumentRevision-V100 folder (as well as preventing any ‘Save’ issues.)
