I already posted a step-by-step guide on how to delete old backups from your Time Machine drive in order to free up space. What I did not mention in that article was how you can delete single files & folders from within backups, if you want to have even more free space available for future backups.

The steps to do so are slightly different – especially the fact that you do not navigate to your backup drive in Finder, but use the Time Machine application instead.

Here are the instructions, if you want to delete specific files & folders from existing Time Machine backups:

Recently I discovered, that my external harddrive for Time Machine backups is slowly running out of space – only ~20 GB left on a 320GB drive.

Searching through the web I did not find any up-to-date help on how to properly remove old backups in order to have more space available. But when trying the most easy and obvious way, I figured out that’s how Apple intended to do it:

I just upgraded my OS X Snow Leopard install to the new Mac OS 10.7 Lion and I am stunned: never before the upgrade process was so easy and fast! Once again it’s amazing what job the Apple Developers achieved, considering it’s a full operating system upgrade.

There are enough posts and reviews about 10.7 Lion, so I am not going to write anything about it in general. But I provide a (happily) short post-upgrade checklist of the things I had to take care after upgrading.

This is the best solution I found in the world wide web to overcome the missing feature, to use Front Row on a secondary display screen:

1. Download the tool displaysInfo
    
2. Start Applications > Utilities > Terminal.app
    
3. Drag-n-Drop the displaysInfo-file to the Terminal window & press Return
    
4. Read the DisplayID of the display you want to send Front Row to
    
5. Execute the following command in the open Terminal window (replacing “xxxxxxxx” with the DisplayID of your preferred screen):

   
   defaults write com.apple.frontrow FrontRowUsePreferredDisplayID xxxxxxxx
   
   

 
Whenever you have now that display connected to your Mac, Front Row will use it to show up on that screen, no matter what your main display is set to. The nice “side effect” of this whole solution is, that you only defined a “preferred display” – so when it’s not available, Front Row just starts on the primary screen.

Heute hatte ich ein seltsames Problem mit AirPort auf meinem Mac. Und zwar konnte ich AirPort nicht mehr über das Menüelement deaktivieren. Es passierte einfach gar nichts, wenn der Befehl ausgewählt wurde.

Nach kurzer Suche fand ich den Grund in den AirPort-Settings. Wobei dies nicht unbedingt die Ursache ist, aber zumindest das “gewünschte” Verhalten zurückbrachte.
