Since installing this update I observe on my intel based mac that two PowerPC based apps now crash immediately on launch. Logging “Exited abnormally: Illegal instruction” to the console. The two applications affected so far on my system are CanoScan Toolkit X and more importantly Retrospect. Unfortunately the installers for both applications also fail with the same error. I worked around the canon issue by installing the LiDE 35 driver (for my LiDE 50) – then using “Import image…” in Preview. However not found a workaround for Retrospect yet. Looks to me like Rosetta is not working properly, although I have one PowerPC process running “RetroRun”.
Annoying and scary for my backups to be crippled in this way. Investigating. Not sure it was the security update as yet, only ‘evidence’ being the timing of the failures.
Update: Solved…
The following typed into terminal, followed by a re-start fixed the problem…
sudo update_prebinding -root / -force
