macOS Big Sur 11.2.1 addressed an issue that could prevent the battery from charging in some 2016 and 2017 MacBook Pro models.

A newer macOS Big Sur 11.2.1 build also fixed a very serious installation issue where not having enough free space available for a macOS Big Sur update could lead to potential data loss.

    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..

    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.
