OS X El Capitan Beta Supplemental Update Available to Fix App Crashing
Apple has released a small supplemental update to OS X El Capitan Public Beta. The small update is available now from the Mac App Store Update mechanism and it fixes an issue that may cause some 32-bit applications to quit unexpectedly.
If you’ve been experiencing some random app crashing since running the OS X El Capitan beta, this may resolve those problems, assuming the apps are 32-bit versions. Keep in mind that beta system software is expected to be buggy and crash prone, and even with such an update it won’t be widely stable until later releases of OS X 10.11.
Installing the update, which is officially labeled as “OS X El Capitan Beta Supplemental Update”, requires a reboot of the Mac.
The supplemental update is available for he freshly released OS X El Capitan Public Beta, it is not necessary for the OS X 10.11 Developer Beta, which apparently does not include the 32-bit crashing issue. Even though the update is small, it’s still a good idea to back up the Mac before installing the update.
