Mac OS X 10.3.9: Problems launching Classic, fixes

Some users are unable to launch Classic under Mac OS X 10.3.9.

One potential fix involves first starting up Classic with the "Shift" key held down to turn off all extensions. Then, once in the Classic environment, using the Extensions Manager to turn off the "Apple Menu Options" extension, then restarting Classic.

We've received several notes from readers who have successfully applied this workaround.

MacFixIt reader Karl Brooks writes "I tried the suggestion and disabled the Apple Menu Options. It worked. Classic started - although, still very slowly - and so far has functioned without any problems."

Some users are able to resolve this issue by simply re-installing the Mac OS X 10.3.9 combo updater.

Meanwhile, some readers now report that simply starting Classic with Extensions off once is enough to eliminate subsequent startup problems.

MacFixIt reader David McKinnon writes:

"I also couldn't get Classic to start after installing the 10.3.9 updater on my G4 400 (Sonnet 1Ghz upgrade). However, after successfully starting Classic with extensions off, I restarted Classic with my usual set of extensions no troubles at all."
