I have some strange vertical and horizontal lines when I enter in Time Machine.
I've checked for errors on the the graphic card but it's working fine.
Specs:
macOS Sierra 10.12 (16A320)
iMac (Retina 5K, 27-inch, Late 2015)
iMac with Retina 5K display, macOS Sierra (10.12)
Hi,
I have the exact same problem. I see that "Apple Engineers" did not solve the problem until now. I have downloaded every possible update whenever it's available for me. Looking forward to any news, because it's quite annoying to buy a $2k laptop and still have issues like that.

Take it to an Applestore & register your dissatisfaction there, it appears to be faulty & you are under no obligation to accept faulty goods (your rights vary per region but you should have at least 1 year warranty).
If you simply keep waiting you are accepting the fault is not severe in the eyes of Apple & consumer law - it makes it difficult to get a resolution in the future, especially after a warranty lapses.
This has been going on for almost a year for some, how long are you willing to wait?
Same issue with my iMac!
Waiting too for an update!
MacBook Pro Retina 15'' (Late 2014)
macOS 10.12.6
Keep submitting feedback via this link and be hopeful for a fix!
What is NVRAM?
A small amount of your computer’s memory, called “non-volatile random-access memory” or NVRAM, stores certain settings in a location that OS X can access quickly. The settings that are stored in NVRAM depend on the type of Mac you're using, and the types of devices connected to it.
Information stored in NVRAM can include:
- Speaker volume
- Screen resolution
- Startup disk selection
- Recent kernel panic information, if any
If you experience issues related to these features, you might need to reset the NVRAM on your computer. For example, if your Mac starts up from a startup disk other than the one you've specified in Startup Disk preferences, or if a question mark icon appears briefly when your Mac starts up.
Hi and thanks Chris,
I've reset NVRAM but lines are still visible on Time Machine (only). Strange... I think it's a software issue, not with logic board battery as stated in your link about how to reset NVRAM, but maybe I'm wrong. Everything was fine before upgrade to macOS Sierra.
Thanks,
but this also didn't work. But can you write which profile should I use or should I calibrate my current profile?
It's still the same. But in ColorSync Utility i have these errors (I don't know of this is related in anyway with topic, but I'll post it here):
Searching for profiles...

chris,
Could this be the beginning of the graphics card failing? I had an iMac 24", a few lines started, then many lines with an outcome of it not working at all (lines).
Just a thought.
@JayB - Changing user didn't work. I'll try reinstall, but I don't have the time for this at the moment to do that 🙂
@Garrat - it would be a shame if it is a graphic card because it's only a few months old mac.
I hope its not the graphics card as well. And I hope you find an easy fix.
