iMac Retina 27" Late 2015 Mission Control Error Lag
Hello everyone!
Searching the web for anyone having the same Problem with lag (in my case even spradically malfunction) of Mission control, brought me here.
You can see, Mission control not even appearing, after hitting F3.
This happens sporadically.
Mostly after working for a couple of minutes.
I usually have opened some windows, e.g. 2x safari, mail, messages, cal, finder. Not quite a lot.
This is still the same Problem for me since Dec. 2012 until now.
I find it quite frustrating, to be honest.
I also updates RAM from 8GB up to 24GB – but no effect on this.
MK472D/A
Apple iMac 27" Retina 5K MK472D/A Intel Core i5 3.2GHz, 8GB RAM, 1TB Fusion, AMD Radeon R9 M390 2GB
Please look here at the videos I posted to YouTube:
1st video I recorded in Dec. 2016
I hit F3 and the only thing that happens is some kind of "twitch of the screen".
2nd Video I recorded today
In this video I hit F3 several times. Sometimes it works, then again it won't work.
Additionally I changed settings in the preferences of macOS to "reduced animation" (or sth like this in english) and "increase contrast".
Doing this and waiting for about 4 Seconds lets Mission Control Error occur almost every time reproducible.
History:
- 1st iMac
- Bought this very new iMac in Dec. 2016
- Updated to macOS Sierra and transferred my account with Migration assistant
- Issues with malfunction of Mission control
- On the 2nd day I sent it back to seller and one week later got another completely new one (with other ID of coarse)
- 2nd iMac
- Now I only updated to macOS and DID NOT transfer my account. But still this issue.
- Called Apple Support and I was adviced to wait for the next OS updates ;-)
So the second new iMac showed the same failure! That all was in December 2016.
Now, June 2017, it’s not solved at all and still making me crazy.
If coarse I have installed lates OS every time there was any available in the last half a year.
But still having the same problem.
I'm a little unsure whether to all the discomfort in backing up and deleting my mac to carry it to the Apple store. And after that, in case of replacement, re install everything, just to find out, that nothing changed at all with this stupid error ;-)
So, what is your opinion in this case?
Have you ever seen Mission control not working like this?
Thanks in advance,
regards,
Klaus.
