white fading border around macbook pro display
So I have a mid-2015 MacBook Pro, and its now 2023. I am following on from an identically titled thread from 2020 which now seems to be closed, with no resolution. Here's the issue:
Returning to a sleeping Mac, with lid closed, on opening the lid the screen was black. No amount of pressing keys, pressing power button, openine and closing the lid would bring it to life. I pressed the power key long enough to shut down the machine, then pressed it again, and the machine responded, with this:
This is identical to a previous poster and their respondents in 2020. As with the previous poster, the Mac booted up, with its white border, which slowly is disappearing as time progresses. Previous posters did not have a re-occurence of the issue, but not knowing what caused it and what may cause it again, and if ignoring the warnings may prove inconveniently fatal to the machine, it would be useful to know if anyone has found the cause of the problem.
Battery issues were considered with the previous poster, but did not lead to identifying a cause.
Fwiw, I'm still running Yosemite (I know, I know..., but I have my reasons). The problem seemed to occur with later OSs as well.
