Be Careful If You Own an Old Mac

macOS Big Sur is available for Macs as old as 2013, which is great for long term support, but if you are at the edge of this compatibility, you may want to hold off on installing the update. Let other users try out macOS Big Sur on an old MacBook Air to see how it performs. 

This will let you decide if the performance is fine, or if there are issues that will prevent you from reliably using your Mac. Check sites like the MacRumors forums and Apple Discussion forums to hear from users with similar devices. 

The update is apparently bricking older MacBook models. The problems appear fairly widespread and they're mostly impacting owners of 2013 MacBook Pro and mid-2014 MacBook Pro models. These are the oldest MacBook models supported by macOS Big Sur.

You are able to downgrade to macOS Catalina so you can test macOS Big Sur out, but you'll want to make sure you have a good backup and that you have time to downgrade if macOS Big Sur isn't what you expected.

    Big Sur is terrible. My computer runs so much slower I’m ready to throw it out the window. Don’t download this program.

    cannot maintain connectivity of screen share. One or both of us lose screen control. constant disconnects and frequent reboots. covid forced at-home business is getting impossible with Big Sur.

    I have a brand new 2019 MacBook Pro and my partner has a fairly new 2016 MacBook Pro. We were doing just fine on Catalina then switched to Big Sur and everything went to hell…we gave it a week to settle in with all of its syncing and updating stuff but then found that performance issues and bugs like entire system shut downs and black screen and spinning wheels started happening… this is supposed to be the best hardware we can buy and yet hampered by Big Sur and its issues is causing us to rethink going back to Catalina.

    I have a MacBook Pro 2016. Big Sur automatically updated and as a result I can no longer use the MBP as a clam when connected to my BenQ 2700 monitor that I need for photo editing. When I try to log into my MBP in clam mode the screen goes blank after about 10 seconds and says it is not receiving a signal. Seriously! This latest update was supposed to sort a few things out for 2019/20 MBP …. not f**k a 2016 model… Unbelievable. Thanks Apple..

    Big Sur update 11.2.1 and now 11.2.2 will not update on my iMac (Retina 4K, 21.5-inch, 2019) It seems to download but when installing i get a error message that there is a problem with my internet connection.

    I have updated my MacBook Air late 2020 to 11.2.3.
    Can’t really see any difference. Since I bought the
    new MacBook the only problem I’ve had (which is very
    annoying) is that the auto login option is greyed out
    and I cannot disable the automatic login. In Library/
    Preferences the com.apple.autologin etc. is missing.
    Surprisingly enough I installed MacOs Catalina on my
    old MacBook Air mid 2012 and it works perfectly.

    Actually i have a macbook air 2017 whose battery was not charging when i was using Catalina OS after updating it to the Big Sur the battery is charging now and is giving around 3 hours of battery backup. Will change my battery with in 10-15 days. Updating macOS worked well for me.

    Same here.

    After installing the 11.2, I had my laptop running crazy and my battery, which still held 9-10 hrs, got depleted to roughly 4 hrs….

    2017 Macbook Pro – updated Big Sur about three months ago and Touch Bar stopped working when restarted. Updated to 11.4 hoping would fix and now camera is black and doesn’t show content (system says it is there but nothing). Have tried so many things but nothing but frustration.
