TOPIC

    If SoftwareFPU and Mac OS 8.5 are installed on a Power Macintosh, the computer crashes at startup.

DISCUSSION

    There is an interaction between Mac OS 8.5 and SoftwareFPU, made by John Neil & Associates, which results in a crash upon restart, if SoftwareFPU is installed. The crash is actually happening in the new Folder Actions faceless background application, but the issue is due to a complicated interaction between the Thread Manager and the way programs exit.


    This is fixed in Mac OS 8.6, and you should download the update from Apple's software updates server. Meanwhile, a work around is to disable either SoftwareFPU or Folder Actions via the Extensions Manager. This eliminates the crash for most users.

    There may be other applications which use similar code to what Folder Actions uses. Such applications will also crash when quitting. Software developers have been notified as to how to fix this issue.
