macOS Big Sur 11.2 update - installation highly recommended

macOS 11.2 Big Sur Update

Apple recently provided mobile devices with the latest software version with the iOS update to 14.4. After the update, as far as I know, there were no reports of a deterioration in the battery life or other problems that would have resulted from the update.

Accordingly, I hope that Big Sur's macOS update only fixes bugs and doesn't add any new ones. In some Mac forums it was criticized that the bug with the suddenly appearing screen saver was obviously not addressed (according to the version report). However, some things are also fixed in the background without Apple writing a comment in the changelog.

(Almost) no known problems from update

However, there doesn't seem to be any major problems with the macOS Update 11.2. I couldn't find any multiple references to crashes, malfunctions or the like in the common forums that would have occurred more frequently after the update. If someone does know something, it would be great if he or she could leave a comment here.

The update to macoS 11.2 should be installed as soon as possible to remove critical security gaps.

Update 02.02.2021/XNUMX/XNUMX - reader comment

After the update, my reader Uwe got a bitching Apple Mail and sent me this comment:

Since the update to BigSur, I've only had two problems. One concerns mail. Sometimes it takes forever for Mail to start. Mails are not picked up, the app does not react at all. Ending the process and restarting Mail does not help. Only restarting the iMac will fix the problem. So far this has happened 5 times, once I had to restart the Mac twice. The usual adjustments that you can find on the Internet did not help.

I couldn't find anything like that in myself. So far, my M1 MacBook Pro continues to run smoothly and everything is as before.

What does the update to macOS 11.2 bring?

Here is the exact wording that you get when you click on the text "More info ..." in the software update window:

macOS Big Sur 11.2 Update 11.2 - Reboot required

macOS Big Sur 11.2 improves the reliability of Bluetooth and addresses the following issues:

  • External displays can show a black screen when using a HDMI-to-DVI converter to be connected to a Mac mini (M1, 2020).
  • Edits to Apple ProRAW photos may not be saved in the Photos app.
  • iCloud Drive can be deactivated after switching off the iCloud Drive option “Folder 'Desktop' & 'Documents'”.
  • Unlocking the system settings may fail even though an administrator password has been entered.
  • Pressing the globe button may not open the "Emojis & Symbols" area.

Some features may not be available in all regions or on all Apple devices.

Update recommended due to security patches

The above-mentioned iOS update 14.4 contains numerous bug fixes as well as a correction of some critical security holes. These have now also been fixed with macOS 11.2, which is why an update is strongly recommended.

The critical security updates fix the following problems (also with Mojave and Catalina!) That Apple here describes:

  1. According to the app, there was a way that a malicious app could gain access to the kernel.
  2. In the WebKit Framework, which is used in both macOS and iOS, there were also two security problems that allowed code to be listed via the browser. This is said to have affected both Safari and Chrome or Firefox users, as the browsers all use WebKit and thus offer the same vulnerability.

Since these security holes should be fixed urgently. Sometimes there are security problems that can hardly be exploited in everyday practice because the technical hurdles are too high. In these cases you can usually wait with the update if you are only sitting at home with your Mac anyway. In the current case, however, exploiting the vulnerabilities is much easier, so that an update should be carried out promptly.

I installed the update last night and haven't found any bugs so far. All programs work as before and there is no noticeable deterioration in speed.

Run macOS update

As always, you can find new updates via System Settings> Software Update> Check for Updates. The corresponding update will then be displayed here, which you can then carry out. The Mac has to be restarted during the update and you may also make a backup before it starts - that's for sure.

    I only have the second problem with BigSur, but the app itself has also been updated. It's about Adobe Lightroom Classic. If I switch to the map module in the app, LR crashes immediately without any further feedback. After restarting the app, I can access the map module without any problems. I send the automatically generated error reports every time, but Adobe has not responded so far (I did not expect either). In my opinion, this problem has less to do with Big Sur and more to do with Adobe or Lightroom.

      Hello Uwe! Thank you for your feedback. I can't find any problem with mail at the moment. Everything continues to run smoothly for me. And with Lightroom Classic, it could really be up to Lightroom. I don't even know if this is officially supported by Big Sur. You should have a look at Adobe. But I'll add your note on Mail at the top of the post. LG!

        Incidentally, I have now probably found the cause of the problems with mail. I use SyncMate as a backup app. This app starts unsolicited with the registration (without having saved it) and then starts with all jobs at the same time. If I close the app, the paralysis of Mail is over and it runs as quickly as usual. All other apps on the Mac have no problem with SyncMate, so I can continue working. I'll watch that.

        Is there an app that shows hidden startup entries and allows deactivation? It is not entered in the login objects, not even via the app's context menu in the dock. There is no such option in SyncMate itself. I also find it annoying with SyncMate that all jobs start at the same time (I have a few jobs that build on each other) and you can only stop them all at once. Delayed start of jobs after login is also not possible.

          Hello Uwe! I would give you the software KnockKnock recommend. You can use it to find persistent programs running in the background. But I'm not sure whether you can simply deactivate it with it. But interesting that SyncMate is apparently the culprit here. I would never have thought of that.

          • Uwe says:

            Thanks for the tip. Yes, KnockKnock will find the file with which SynMate starts. But I could only delete it. But it is required for the app if you want to start it. I'll keep watching this and check with SyncMate the next time Mail runs into trouble. I can't really imagine that an app only affects one other app.

            If this is confirmed, I'll deal with GoodSyn again. I still have a license there.

    Thanks, Jens :-)

      So, little update. SyncMate support recommended that I install an older version (3.2x) of macFuse. I had version 4.0.5 installed. I did, but then VeraCrypt stopped working. So again macFuse 3.2.x uninstalled and 4.0.5 reinstalled. In the end I changed all backup jobs and synchronizations to GoodSync and SynMate and uninstalled it. Since then there has been silence (7 days, knock, knock). The Mac also shuts down faster, Mail no longer zicks.

      I don't want to say that it's up to SynMate alone. As in the Windows world (????) there are incompatibilities here and there. SynMate may also work with the current version of macFuse, but at the moment everything is causing problems for me in conjunction with VeraCrypt.

      Either way, I'm quiet at the moment (I'll be cautious for a few more days). I'll write off the money invested for SynMate and it's good.

  3. Fontbook always crashes with me and cannot load new fonts

    Hello everyone, I have had a problem with external hard drives since 11.2: I no longer have access rights and unfortunately I cannot change them, although as an admin (I) I should be able to read and write. Does somebody has any idea?

    Thank you, Andreas

    • Andreas says:

      ps "read" and copy from the external disk is possible, "write" and z. B. do not create new folders.

      • Jen Kleinholz says:

        Hi Andreas! I would iron the system over again. Just restart and hold CMD + R and then reinstall macOS. That fixes a couple of things.

  5. Peter Knechtli says:

    I find the mailbox representation of the mail program in the BigSur mail program miserable. Why can't endlessly created spam, sent and trash mailboxes be combined? Incomprehensible!

    Does anyone know how old (simple) folder representation can be set up?

    • Jen Kleinholz says:

      I could imagine that it is because it is IMAP mailboxes that simply manage all these folders separately. But maybe someone else has an idea.
