Screen freezes in Big Sur 11.2.3

I am not sure which Mac you have since you did not mention it. I will therefore attempt to answer your question in the best manner that I can. I will assume that you do not have a M1 based Mac.

You may want to try some basic troubleshooting techniques and see whether that resolves things.

1. Reset SMC by following the directions applicable to your MacBook here ➔ How to Reset SMC. If that does not solve things then-
2. Reset NVRAM/PRAM by following the directions applicable to your MacBook here ➔ How to Reset NVRAM/PRAM. If that does not solve things then-
3. Enter ➔ Safe Mode and see if the screen issue still exists in Safe mode. Log out of Safe Mode and then reboot computer. If that does not solve things then-
4. Finally if none of the above works then you can enter ➔ macOS Recovery Mode and reinstall the macOS and see if that solves it.

Axel,

I have reported this problem to Apple Support 3 times and advices the same steps you had given above. I had follow from steps 1 to 4 (MacOS recovery) but guess what, Freezing screen remain without fix...

Tell me what went wrong... this is all after Big SUrf OS upgrading...

BAD BAD BAD

iMac 2021, 128GB ram, 12 core.

Freezes and crashes in Firefox, Chrome and Spotify desktop app.

Multiple peripherals connected.

Tried booting Safe mode. Things ran "fine" (very slow, as in Safe Mode)

Booted into Recovery mode and did a Fresh install. Seems to have done the trick

found something that might be the caused...

So happen i have two unit of Macpro 13", one unit is from manufactured in 2019 with touch bar on keyboard and another was manufactured 2020. Both were installed with Big Sur OS and the 2019 unit has never freeze with whatever applications running. On the other hand the 2020 unit keep freezing if i do open Safari or Chorme Browser. Well, what i want to mentioned here is, the 2019 CPU processor was made of Apple M1 chip whre 2020 was Intel CPU. I do not know if this is the main caused but that is my finding....

Please provide your view...

Hi Axel,

I have same problem with M1 (MacBook Pro 2020) with macOS Big Sur 11.3.1

So mouse or touchpad freezes for 2 sec periodically. It may happen more often by switching from one application to another or switching to another desktop. Everything worked well until the last update.

I use this laptop for business, losing any file would be a disaster for me.

Do you still recommend steps you listed?

Is there a risk of losing any file?

Thanks,

Darko

Yes I do. The key here is that you would perform one step at a time in the order listed. Check performance of your MacBook after each step. For example, if step 1 solves the issue, then you wouldn't move to step 2 and beyond because it will be unnecessary.

You are welcome.

Does resetting SMC will loose all your data in your Mac?

No. Data will not be lost.
