How to fix FDT (or any other Eclipse-based IDE) after Mac OS X 10.6.3 upgrade
Posted on 2nd April 2010 in Developer tools, Eclipse, Flash | 6 Comments »
The most recent Mac OS X update to version 10.6.3 may break your Eclipse Galileo installation and everything that’s built upon it. It just fails to start and closes down right after it has reached the splash screen.
The problem relies in the corrupt font cache of Snow Leopard and the fix is rather trivial – font cache needs to be cleared using the font registration system utility on command line. Following steps will make it happen:
- Close all running applications
- Start Terminal from Applications > Utilities > Terminal
- Run
sudo atsutil databases -removeand enter your admin password atsutil server -shutdownto shut down the font registration systematsutil server -pingto restart- Log out and back in
FDT should now launch properly!
UPDATE 21.06.2010: Eclipse (3.5.2) is also broken on Mac OS X 10.6.4! The above fix works nicely there as well.

The above solution didn’t work for me, however I was able to do it by cleaning up Duplicates in FontBook

Did not work for me either.
Many thanks! I had a problem with Eclipse Galileo after upgrading to 10.6.4 and that fix worked well.
Thank you for this tip… Finally I can get Aptana 2.0.5.1278522500 working on my SL 10.6.4 …
But I have to clear cache on every boot! There’s a problem with Aptana or with computer configuration?
Thank you!
