I just want to know is it ok or not? Is it flawed or not? I have no other MacBook to compare or friends with this laptop to ask if it’s normal. That’s why I created this post. Please just tell me does your MacBook shuts down with similar effects or not. Thank you!
Apologies for my tone/response. I must’ve been in a really bad mood because I’m normally quite friendly and helpful around here.
I think my 16” MacBook Pro would “flash” during shutdown and I experienced some other minor graphical glitches during use (invoking the dock while playing a game induced a subtle flash as well), but these have been fixed in recent system software/graphics driver updates and do not happen anymore. The screen turns off completely cleanly/normally now.
In my not so educated opinion, I think it’s very unlikely that the behaviour you’re experiencing indicates a hardware flaw; more a graphics driver glitch or quirk. If you see ongoing problems during use that’s another matter because it affects your use (and confidence) in the device.
In that case Apple may choose to replace or repair the computer even if it’s a software/driver problem. They sometimes do this if they don’t yet know what the problem is or how to fix it. Plenty of people have reported requesting replacements (sometimes multiple times) for all manner of problems only to find that the replacement exhibits the same issue(s).
That’s why it’s not always best to rush into returning a unit for something that is likely a software/firmware issue or could possibly be fixable by an update, but this decision really depends on how serious the problem is and how much it affects your use of the device. It’s really up to you. If it affects your use you’re more than entitled to return it or request replacement.
I guess what I was trying to say (rather unsuccessfully) is that a flash or funky pattern on the screen when you’re shutting it down really doesn’t affect your use of the device and on its own isn’t worth worrying too much about. I’d have waited to see if software updates fix it. You have a 1 (or 2) year warranty with the option to buy more to cover any worsening of issues should they arise.
