MacOS Big Sur Unstable

Has anyone else experienced MacOS Big Sur being really unstable? My MacBook Pro often freezes when shutting down and I have to hold down the power button to get it to power off. Also most apps freeze when quitting them and I have to Force Quit them. It's just unstable and doesn't seem that great. I'm running a MacBook Pro (Retina, 15-inch, Mid 2015) with 16GB or RAM.

To verify it's not a 3rd party software issue Apple had me do the following:


1 - make sure I had a full and current backup of my hard drive, either Time Machine or a full clone.


2 - Boot into the Recovery volume, erase the drive and reinstall the system without migrating any files from my backup. Run and see if the crashing continues. If it does it's hardware or the system. If it doesn't then the user files are the culprit.


You might try the above to verify that it's no any of your files or 3rd party apps that the culprit.

Amen and thank you for this. I have grown increasingly concerned recently that we are back in the late 90’s with innovation stagnation and a general acceptance of mediocrity. The absurd lack of responsiveness of the OS in general - in particular in notifications, the “click bloat” and frankly frequent failures at the kernel level taking the entire system down for unknown reasons are unsettling. Hard to tell if anyone at Apple Park Way is paying attention....

After years of using MAC, I am close to going back to Microsoft. My configuration did not change. I upgraded to Big Sur and have so many issues. Not only are MS apps crashing, I have Page and Keynote crashing.


Question should I wipe my system and reinstall ? That is what I use to do when I was on MS. I reboot more often.


I am heading back to the U.S in May to take my system to Apple Store. Apple does not have a Apple store here in Phnom Penh.

The local apple partner needs to hold my MacBook for 4 months to change the battery. Not sure why they need to keep it for 4 months.

They recommended NOT to use EtreCheck and had me uninstall it.

If you have any concerns or questions about EtreCheck I would be happy to answer them. This forum would probably not be the appropriate place for that however. I'm not even allowed to give you a link to the website where you could send a support request. You'll have to Google it on your own.

Sorry to jump on the complaint wagon. Not only the office products are crashing, Pages, numbers, etc occasionally crash.

My MacBook Pro runs very warm so much so it slows down. To avoid the over heating, I have a fan blowing directly on the MacBook.


If my dell had the same UI as the Mac, I would swap in a minutes. I am not a fan of Ubuntu Desktop.


Is this a strategy to get folks to upgrade to the M1 Macs?

Amazing all of the "it's not me, it's you" replies here. This OS is a real problem that Apple needs to address. I have to Force Quit/Restart roughly 2-3 times daily and I'm not a heavy user. This is on a brand new Macbook Air that I purchased three months ago. I never experienced this with my previous Macbook Air products using Mojave and its predecessors.


Apple really needs to understand that a lot of PC users originally moved to Apple because "they just work". Between these hangup issues and their 'forced upgrade' approach, I am (quite unbelievably) actually considering moving back to a PC.

I've mentioned that for me and everyone I know it's been the fastest, most stable version of macOS we've used.


As far as peripherals and software, that's up to the relevant vendors to make sure they are compatible with the new version of macOS. Developers and peripheral makers are seeded with the new operating system for at least a three to four month beta period to ensure functionality, and too many don't bother to do anything until it is actually released.

I don't mean to diminish your experience, but your issues do not mean Big Sur is fundamentally unstable any more than my experiences mean that it is.


However I work with hundreds of others who use Big Sur every day and their number of issues is also zero.


Given that, it's vital to try and sort out what is different about your system than mine and try to track down the issues.


Some people have narrowed some down to issues with sleep mode, but otherwise I can say I've been using Macs since I bought a Macintosh II in 1988. Like you, most upgrades have been reasonably painless though a few were not.


Still, I have never experienced a faster, more stable Mac OS devoid of issues than macOS Big Sur.


I can compare that to my Mac Pro 5,1 running macOS Mojave, which while basically stable has moments where it is not at all; in fact power cycling a printer after it failed to connect to a shared folder on my Mojave Mac caused it to panic just the other day:
