Earlier today we reported that users were having issues with external hard drives crashing their new MacBook Pros. It seems Apple has just released macOS 10.12.2 beta5 and this fixes the issue these users were having. This will only fix the issue if you’re willing to run macOS 10.12.2 beta5, which is not stable software. If you’re not willing to run macOS 10.12.2 beta5 and want to stay on macOS stable, then you will have to wait until Apple pushes the update to the stable channel.
Updating to 10.12.2 beta5 solved the issue for me.
What I found VERY curious is that after installing beta5 on a separate volume, my main macOS installation (regular 10.12.1 that had previously been definitely afflicted with the issue mentioned here) also became stable. Since experimenting with beta5, I cannot invoke a crash during a copy operation. And believe me – I’ve tried!
I also just updated and can confirm a few things:
- The CR2 file that caused a system crash 100% of the time now doesn’t cause it. I’ve tried to recreate the failure and can’t.
- The Boot ROM & SMC have both been updated (2016 15″ 2.9/460)
Boot ROM MBP133.0226.B08 SMC Version: 2.38f6
- Time remaining for battery life has been removed however I *think that it’s consuming or reporting less consumption anyway.
- Still seeing artifacts under Spotlight Search bars although not 100%… about the same rate as before.
- I’m still seeing black lines vertical & horizontal (as if trying to outline windows perhaps?) around the open windows in Time Machine.
- I haven’t been able to reproduce the green & red lines on the screen in a while even before the update but I will certainly report back if it reappears.
I can confirm the issue has been fixed for me on the 10.12.2 Beta! Just completed my first successful backup on the new machine whereas previously it would fail every time.
So it seems Apple is listening to its users, which is a good thing to see. Unfortunately those users not brave enough to try beta software will just have to wait until the fix is available in the stable release. Now Apple just has to address the situation with the battery life on the new MacBook Pros.
