Some 2015 Retina Display MacBook Pro owners experiencing system freezes under OS X 10.11.4

Well, this is sort of a mess.

A large number of MacBook Pro owners running OS X El Capitan are reporting widespread system freezes since installing the 10.11.4 update to Apple’s Mac OS.

Hundreds of users have posted to a dedicated thread discussing complete system freezes on the early 2015 13-inch Retina MacBook Pro notebook running OS X 10.11.4. Users have reported that their system becomes totally unresponsive at seemingly random times, with no way to regain access to their Mac other than to force a hard reboot.

Many users have reported similar freezes after updating to 10.11.4, with some 15-inch MacBook Pro (Mid 2015) owners also experiencing issues. One potential cause has been identified from crash logs as a system framework or an Intel Graphics driver bug. The issue is also being reported after installing Safari Technology Preview Version 1 and OS X 10.11.5 Public Beta 1.

In the video below, user Bill Mattheis documents the hard freeze:

Apple’s support staff is apparently aware of the issue, but has yet to offer a concrete solution to resolve the problem. In the meantime, some users have resorted to downgrading their system to 10.11.3 by restoring from a Time Machine backup or performing a clean install.

If you’ve seen this issue on your end or have any feedback to offer, please let us know in the comments.
