macOS sierra 10.2.1 closing lid = crash & b...

Hello!

Since I upgrade my MacBook pro (15 inch - mid 2015) to macOS sierra, the brightness cannot be adjusted (neither with F1 & F2 buttons nor by going into system preferences). Auto-brightness is turned off.

Another issue I have is that I often just close the lid without turning it off when I just step away from my desk in the office for a while. Since upgrading it will crash every time I reopen the lid again instead of waking up and prompting for the password.

Does anyone experience similar issues? If yes, how did you fix it?

Thanks for the help in advance!

Hi & thanks your answer!

I tried resetting it as described in the link but that didn't work for me. Still can't change screen brightness and laptop still keeps crashing.

This is the report for the 'Sleep Wake Failure' I got this morning (maybe it helps...)

I have never personally encountered this error. I did some research on the web and people who encounter the same problem we solved their concerns to the apple store... If you have time try to make a backup of your machine and to reset it ...

thanks - was thinking of that too but wanted to avoid it... Looks like i'll give it a shot and if that also doesn't help take it to an apple store.

How did you solve this in the end (assuming that the problem is solved now). I get the same issue now after upgrading to Mac OS High Sierra,
