Also I would like to add that I cannot get my usb adapter as built-in. And I do belive that this is the cause of "Error while communicating with the server" when logging in with iCloud.
Also the usb adapter seems to work only if I plug it in when the laptop is powered on, if I power it on when the adapter is already plugged in it doesn't get recognized.
I tried to add all thunderbolt's pciroots to device-proprieties and built-in but it seems like it didn't fix it

That cannot be set as built-in. You'll need to use Null Ethernet.

yes I figured out it was a power spike. Cpufriend and cpufriend data was not loaded in the correct order
I was wrong. The problem is not fixed. I tried to remove many things like acpi patches, kexts and such but I don't get why this happens only when it's battery powered. When it's plugged into ac there's no problem, also this didn't happen in windows. Is there some kind of log that I can see some power events or things like that?

There is still acceleration issue?

No. I changed the DVMT variable to 64M and the acceleration issue is fixed.
Also my dell laptop have an handy bios log, everytime the pc shuts off like this it registers "ASF2 Force OFF".
I don't think that this is related to the bios version as I already changed it a few times and the issue is still there.

This thread was dedicated for the acceleration. As it's fixed, you should consider creating a separate thread to not mix the issues with each other.

It normally means there was a power issue. I suspect RTC. Provide your BIOS Settings and the PR files to check further. This thread will be closed. Open a new thread and all of the issues can be fixed over there.
