Strange lines on screen only in Time Machine

Yes! My issue has been referred to Apple engineering.

Please correct me if I'm wrong, but for info I believe this is the site to post feedback:

Same issue here.

Late 2015 27" 5K iMac

4 GHz i7

Originally with 8GB ram upgraded to 32GB 1867 MHz DDR3 from Other World Computing

AMD Radeon R9 M395 2GB video memory

3TB Fusion Drive

Running macOS 10.12.1 Sierra

Thin vertical AND horizontal lines in Time Machine. The lines move with and change with and even at times follow the movement of the curser as can be seen in the following photo.

I've also had artifacts upon shutting down and other odd graphics issues along with the occasional total freeze of the system.

That looks quite serious. Have you tried removing your RAM that you are back at 8GB?

Anyhow, you should report that issue as well. This is strictly recommended. Soon, there will be the release of 10.12.2, and I truly hope that they could include a fix for that problem.

Report it to Apple and direct them to this forum

There is a report on 9to5Mac (https://9to5mac.com/2016/12/07/apple-believes-2016-macbook-pro-graphics-issues-a re-addressed-in-macos-10-12-2-update-acc…) stating, that Apple has been addressing graphic glitches, and they believe it is all sorted out with the latest beta version.

I, however, installed that version, and still faced these grey strips. I believe, that they meant fixing other, more serious graphic glitches.

Can somebody verify that who is running the latest beta as well?

I think the majority of posts on this thread relate to the late 2015 5k 27 inch iMac and not the just released MacBook which that article relates to.

However I too would be interested to hear from anyone running the latest beta on iMac 5k late 2015 27 model to see if the graphics issue is still present.

For me it's a 2016 rMB.

updated to 10.12.2

Error still exists

See the release notes…

About the macOS Sierra 10.12.2 Update - Apple Support

…

Resolves graphics issues on MacBook Pro (Late 2016) computers.

That may cover your Mac & this issue (Apple's vague release notes help no-one).

Personally I'd boot into safe mode in the hopes that it causes the update to system cache files that may not have been refreshed after the update.

Go visit an Apple store & let them know it is still broken if you can do so.

The graphic error which has been fixed refers to a different issue, not the grey strips we all encounter in TimeMachine etc.

I am running the latest beta at the moment, but will install the full update today. But I am not confident that this issue will be resolved.

It is quite hopeless that Apple will fix that soon, I believe. I returned my Macbook, and am using the replacement unit now. As I reported earlier, I still have this problem.

Hi,

I have the same problem.

I also tried a clean install of Sierra, but the problem still there.

MacBook Pro mid 2015 buyer 3 weeks ago

I have also noticed strange problems to the Finder window in "Column View":

vertical separetor sometimes doesn't get the bottom of the windows.

I don't think is an HW problem....I thinks is OS bug

See images:

same issue here with a brand new MBP 2016.

It's already my second MBP due to other issue. That issue here has not been fixed with 10.12.2

Can anyone restore from TM? I cannot really browse and cannot restore at all

Same issue here too, MBP 2015, Sierra 10.12.2. Here's a video I captured https://www.youtube.com/watch?v=HnsiPxeiOLQ
