MacBook Pro users are reporting issues with the latest update to OS X El Capitan.
Users report that their system freezes randomly since installing the Mac OS 10.11.4 update, and being locked out their devices, forcing them to hard reboot.
One user told Mac Rumors that, after instilling the update, which was released by Apple on March 21, the freezes in his system have been occurring "about once a week."
The issue seems to be concentrated on 13-inch Retina MacBook Pros — the early 2015 models — running 10.11.4, with some 15-inch MacBook Pros owners also experiencing issues, according to Mac Rumors.
Freezes happen in the Safari browser when switching between tabs or clicking on a hyperlink, as well as Mac apps such as Adobe Photoshop and a number of third-party browsers.
The computer's haptic Force Touch trackpad also completely loses feedback. Installing Safari Technology Preview Version 1 and OS X 10.11.5 Public Beta 1 have caused some problems for users as well.
A bug in the system framework or an Intel graphics driver has been identified as one possible cause, according to crash logs.
While Apple Support is aware of the problem, the company has yet to offer a solution. Some users have already downgraded to 10.11.3 by restoring from a Time Machine backup or completely wiping their system clean.
According to the Daily Express, here's how to downgrade your MacBook Pro to an earlier operating system: click on the Apple Menu at the top left-hand corner of the menu bar and select restart.
After restarting and hearing the startup sound, press down on the Command and R keys at the same time, releasing them after seeing the Apple logo on the screen.
Choose the Time Machine backup disk after selecting Restore From a Time Machine Backup, and click Continue.
Pick the Time Machine backup that you wish to restore. To go back to the way your computer was before you downloaded the new version of OS X, select the most recent backup that took place prior to the OS X El Capitan installation. Then, follow the instructions on the screen.
