The failure to launch is one of the known problems with running ProTools on 10.4.10 and 10.4.11. All versions of PT (LE, M-Powered and HD) on a PPC (and most versions on Intel Mac) are only officially qualified up through 10.4.9.

We experienced the same problem back with LE 7.3 when we updated to 10.4.10. Reinstalling your OS and then using the 10.4.9 combo upgrade is the only permanent solution.

It's a huge pain, I know. We've formatted one of our computers here five times because of various version compatibility problems before we found a combination that works.

Moral of the story: find out what version of OSX your software is qualified to work with, install that version, and then leave it that way. Apple's bizzare obsession with totally overhauling an OS to the point that it makes programs not work makes updating very dangerous. While a new OS version might sport snazzy new features, you should carefully consider the headaches upgrading causes before committing to anything.
