Hello,
as stated above, my MacBook Pro from 2015 is extremely slow and laggy. Even in recovery mode.
I've already reset the NVRAM and SMC.
From research i've found out, that in the past, the hard drive cable was the problem.
As the 2015 MB has no cable like this, is there any other thing that could be broken?
Thank you in advance
Hello adrianknorr,
Thanks for asking the Apple Support Communities about your MacBook Pro.
Since the issue is also occurring in macOS Recovery, I recommend running diagnostics on your computer.

Thank you so much!!
To be honest, i've never heard of the Apple Diagnostics.
It said there are issues with:
A guy in another forum had the exact same issue with the same error codes. He had to clean some spillage from the motherboard to get it working again. As there was no flith on the motherboard, i just unplugged the camera and it worked again! Apple said i have to replace the motherboard which costs 700 Euros. That's a economic total loss.
Now it's working perfectly fine! Thank you so much for naming the diagnostic tool!
