A few MacBook users have discovered that their computers are randomly freezing after updating to OS X 10.11.5. The problem is fairly irritating — the Mac entirely stops responding to input and requires a forced restart, though some have written that disabling WebGL for Safari will help with Safari usage. Apple has now publicly acknowledged the freezing issue with 13″ Retina MacBook Pro models and has put out a support document addressing the issue entitled “If MacBook Pro (Retina, 13-inch, Early 2015) becomes unresponsive when a web browser is running”.
According to Apple the solution to the unresponsive Mac behavior is fairly simple:
- Update OS X and other software from the Mac App Store;
- Update the Flash plug-in, if applicable.
Mac users can update system software and apps on a Mac by going to the Apple menu, and then clicking on “App Store”.
Once there, click the “Updates” section. Be sure to always backup a Mac before installing any system software updates. Flash requires an update separate from Adobe, but an easier approach would be to uninstall Flash completely and use the plug-in sandboxed in Chrome browser instead. The plug-in will update itself along with the broswer.
Updating software is fairly easy and it may well work to resolve the trouble for many Mac users. It is always recommended to maintain system software, apps, and plug-ins at the newest possible stable version available.
The support document was first noticed by MacRumors. However, several commenters on the article noted they were still experiencing system freezes despite running the latest version of OS X. They didn’t even have Flash installed.
What about you? If you are experiencing the unresponsive Mac problem, did the Apple provided solution fix the freezing issue for you? Are you experiencing any system freezing or unresponsive behavior when using a Mac since updating to OS X 10.11.4 or OS X 10.11.5? Let us know your own experience in the comments below.
