From time to time, we hear about OS X or iOS system glitches or software-related bugs that pop up unexpectedly — and these tend to cause Mac and iOS device users unnecessary headaches and frustration.

But today, unfortunately, we’ve caught wind of perhaps the most debilitating computer-related conundrum to have effected the Cupertino-company’s Mac line in, well, a while. Unfortunately, so it seems, some users of Apple’s MacBook Pro — after updating their system to the latest, OS X 10.11.4 ‘El Capitan’ software — are reporting a full-on system freeze, which ultimately leaves them with no other option but to hard reboot their MacBook Pro.

Indicating that “hundreds” have expressed in forums that this issue has effected them, MacRumors reports that it seems the early-2015, 13-inch MacBook Pro with Retina display is the most widely effected machine suffering from this anomaly.

“The freeze seems to affect not only the screen and mouse cursor but also the Mac’s Force Touch trackpad, which completely loses feedback,” according to the MacRumors report.

Several users, including iPhoneHacks’ Killian Bell, reported that the issue tends to present itself even right after their machines have fully hard-rebooted. There appears to be no particular cause for the crash; but rather, as Bell indicated of his own MacBook Pro, “it just happens.”

You can check out the video below, which illustrates a hands-on demonstration of what exactly the crash appears to entail:

According to some crash logs, several users have indicated that they think the issue may be caused by Intel’s graphics card — however, there are numerous conflicting reports to that effect. And apparently, according to other users, the early-2015, 13-inch MacBook Pro with Retina display isn’t “the only” machine that appears to be affected by the bug; but also, some 15-inch MacBook Pros with Retina display also seem to be vulnerable.

Some have reported, with mixed results, that using Apple’s ‘Time Machine’ feature on OS X has enabled them to roll their system back to OS X 10.11.3 — thereby, in some instances, rectifying the issue. Additionally, MacRumors recently indicated that Apple support is fully aware of the bug, though the Silicon Valley Mac-maker has yet to provide a viable solution.

I suppose we’ll just have to wait for the next software update, which will hopefully patch the issue for good, right?

Have you been effected by this crashing bug? Let us know in the comments!
