For users who would prefer to install a combo update or package update rather than go through the Software Update mechanism, you can download those directly from Apple:

Note on lack combo/package updates for macOS Big Sur: apparently Apple is either no longer providing the combo and package updates, or they just haven’t uploaded them yet. This is understandably disappointing as many users rely on these update packages for general use, upgrading multiple Macs, for troubleshooting, and much more. If you wish to have the combo updates for macOS Big Sur, it may be a good idea to send Apple feedback directly about this issue and request them to be made available again.

    I installed macOS Big Sur 11.2 and the latest iPadOS, but now Sidecar doesn’t work. Sidecar times out and can not connect to the iPad. Frustrating.

  2. gyuk says:

    11.2 cant connect Synology NAS, 11.1 works fine, but 11.2 not show in finder my NAS, when i try manual connect not respond.

  3. crypto7 says:

    Where can I download Security Update 2021-001 Catalina? Apple seems reluctant (or at best untimely) to post combo and security updates at lately…

    • Paul says:

      We have noticed the same thing, whether the lack of combo/package updates is intention or just slow we are not yet sure. Hopefully they come soon, as they are widely used by many Mac users!

  4. Kevin says:

    Anyone having issues after installing Security Update 2021-001 Mojave? My MacBook Pro has auto-shutdown literally every 5 minutes since installing. Even if I leave it on the log-in window.

  5. Tom says:

    Hi, yesterday I updated my Mid 2014 MacBook Pro 13 Retina from Catalina to Big Sur 11.2. So far so good, 45 minutes to download and 45 minutes to install. Everything went smoothly with no problems or issues.

  6. Karen S says:

    I down11.2 and downloaded and installed and now I cannot open Firefox; I have to force quit to close it.

  7. JohnIL says:

    Honestly I did not read a lot on issues fixed with Intel Mac’s mostly with Bluetooth and certain external monitor issues on the M1 Mac’s. A bit skeptical that this will really fix the bulk of the issues?? It does contain a lot of security fixes so that’s good I guess. Think I will stick with Catalina for awhile now.

  8. Graham says:

    At last this update fixed my kernel panic restart after doing a software shutdown on my MacBook Pro 15 2016.
    When I did a software shutdown, my MB would start back up. Frustrating!
    The only option was to do a hardware hold the power button to force power down.
    No this update has fixed this problem. Whoohoo from down under Sydney Australia.

  9. Elwood Downey says:

    Oops? The combo and package links just point back here…

  10. TimBits says:

    Links to direct download seem broken.

  11. TimBits says:

    Still has the same install issue as 11.1 for some M1 users that results in a failed to download error.

    • Spruance says:

      Had this issue with my 2015 iMac 27″ and a MachBook air from 2020. It cost me hours to find out that in secure mode (boot with shift-key) the update went in without hitch.

      • Tim says:

        This worked for me! Thanks

        • JI says:

          Very helpful, thanks for sharing.

          Also if you’re trying to reinstall macOS on the M1 Mac you may get a weird personalization error.

          Apple has a support article about this specifically:

          “If you get a personalization error when reinstalling macOS on your Mac with Apple M1 chip”

          “An error occurred while preparing the update. Failed to personalize the software update. Please try again.”

          The solutions are not ideal but good to know if you need to use this.

        • Paul says:

          Thank you for the tip, we have added this solution to the article for users experiencing update errors with MacOS 11.2

  12. Joel says:

    I see your link for the Combo goes to this very article instead of an Apple Update Server, do you have info that there will be an actual Combo installer?

    I know there was no 11.1 Combo, which would not have been expected except for there was that 11.0.1 between 11.0 and 11.1. I heard much discussion around the “rumor” sites that they’d been abolished with Big Sur.

    Looking forward to seeing that link go to an actual Combo!

    Thanks for your great articles!
