Ever so often my OSX Trackpack suddenly stops working in a strange way. Moving the cursor is possible, but clicks are ignored. Turns out the root of all evil is the osx bluetooth stack – again! By simply disabling and reenabling bluetooth connectivity the trackpad magicly starts working again …

There is a severe drawback in Adobe Flash on OS X Lion (10.7). Flash Apps that need access to Camera or Microphone i.e. every Flash Video Chat show the “Allow to Access” Screen, but there is no way to click “Allow”. Currently this can either be worked around using keyboard navigation (tab to the ‘Allow’ button and hit space to confirm) or by manually adding the Sites in the “Camera and Microphone” tab of the Flash Player Preference Pane.

Details about this bug on the apple discussion board. And the corresponding entry on adobes bug tracker.

This week Apple released its newest Operating System Mac OS X 10.7 aka Lion solely through the Mac App Store. It is no revolutionary update, but there are lots of new GUI as well as OS features.

Ars Technica did a great review covering all the new stuff in lion. Read it at arstechnica.com.

Just a short note, because it happens to me once in a while.

If your bluetooth devices like mouse or keyboard stop working in OS X and reconnecting etc. do not solve the problem:

Open your Terminal and execute the following:

sudo killall blued

This restarts your bluetooth daemon and your devices should be working again.

Opening vnc:// urls work well with finder on OSX Snow Leopard. In spite of that, lately i got the problem that vnc connections worked, but only showed me a white screen after that.

The Solution is very simple: go to /System/Library/CoreServices/Screen Sharing.app or /System/Library/CoreServices/Bildschirmfreiegabe for the german version, open the info window and check the ‘Open in 32 Bit mode’ option.
