AMD Graphics stalling on 3 Macs with latest El Capitan udpate

Does anyone know whether or not 10.12.2 is also affected? Thanks.

A friend of mine who used to have this problem recently upgraded to Sierra, and since then, he tells me that he hasn’t seen the problem in two weeks.

As for me, I have a mid-2015 MacBook Pro with an AMD Radeon R9 M370X running 10.11.6, and I’m seeing this problem every couple of days (and then I reboot and I get a reprieve of another two days; repeat).

Thanks, I was thinking about upgrading to Sierra, but I use pdf software a lot, and Apple has messed up pdf in any Sierra version big time. I have redownloaded 10.11.6, this build does not include the faulty security update. Apple software has become super annoying, really wasting my time.

I always do clean installs for major version upgrades. For this downgrade I would also recommend a clean install. Actually, the installer might refuse a downgrade, so you would be forced to do a clean install, but I don't know for sure. I have found over the years and for many OS that clean installs for major version upgrades eliminate a huge amount of small and big issues that might arise and possibly cost you more time than just installing from scratch.

Also just started seeing this on a 2011 27" iMac running El Cap 10.11.6. I recently had to replace the graphics card (AMD Radeon HD 6770M) because of screen artifacts and occasional GPU lock-up failures and was afraid it might be a second bad card. Is there talk of a fix for this issue as yet?

I also have this issue on a MacBook Pro Mid 2015. The issue appeared after the last security update to El Capitan, I believe. I am still experimenting to see what sets it off. Since the problem is intermittent, it is hard to figure out. I have invoked the usual magic incantations: I have tried starting up in Safe Mode and I have reset NVRAM. We'll see.

I also have this problem on my three systems:

* MacBookPro (15-inch, Early 2011)

* iMac (27-inch, Late 2012)

* MacBook Air (11-inch, Mid 2013)

All running 10.11.6 (15G1212). This stared happening after the latest security update.

Not sure what to do expect to reboot when it starts happening (the computer becomes unusable). I have pretty much the same software on all of these computers and all of them are logged in with the same iCloud account.

I'm seeing the same on my Mac Pro (Early 2008) running 10.11.6.

It seems it's new with 10.11.6 for me.

Only thing that helps at this point is a reboot (until it comes back). Makes the machine unusable.

I suppose there's no straight forward way to force it back to an older OS release?

I'm having the problem on a 2011 MacBook Pro running El Capitan.

When it happens, the menu-bar clock stops updating for around 30 seconds, sometimes longer.

It didn't start immediately after installing the last security update, but it's happened to me twice in the past week.

I've also noticed this, on a mid-2011 iMac running 10.11.6. Restarting seems to make the problem go away, at least for several days. I can't identify any behavior that causes it, and once it starts happening it continues every few minutes even if I quit all programs and leave the computer on the desktop.

running 10.11.6

I've also been seeing this on my Retina 5K iMac:

Same symptoms as everyone else. Restarting fixes it for a while, but it's impacting my work now.

I am having this problem as well on a late 2009 27" iMac running 10.11.6

There now is a software update available which appears to be designed to address this problem.
