Problems after Catalina update 10.15.6 (Safari crashes, finder crashes, no network resources)

Hi all,

I seem to be the only person so far with these problems, starting immediately after the Catalina update 10.15.6. Any insights would be appreciated. Machine is a 2012 Mac Mini.

Issue 1: Safari crashes upon starting. Find log below.

Issue 2: any right button click on a desktop item causes a Finder reset (finder windows close, icons disappear for a second)

Issue 3: no network sources are seen, but connections that are already established remain accessible

Most apps work and I'm now using Chrome to access the web.

I had a free version of Malwarebytes running. Removing it did not help.

I also tried reinstalling MacOS but after about fifteen minutes the recovery would report:

'The operation couldn't be completed (PKDownloadError error 8).

I can access the machine via remote desktop: all devices save the power cord have been disconnected and the problem persists.

And finally, the Safari crash log: (figuring out the addition text feature: a standard log appears to be too long even for that.) - dang, I can't seem to manage, even if I split it up.

Your mac does not need any "cleaners".

I see that you have "CCleaner" running all the time.

I understand that is a program originally from Windows, and is often useful on that OS, or at least it was in older versions.

There is absolutely no reason to have it running on your mac.

This may or may not be the case here, but some "cleaners" are well known to overclean, deleting necessary files and causing systems to become unstable.

I would uninstall, and then run the 10.15.6 Combo Update. Sometimes running the Combo can restore files that may be damaged or missing.

Luis, thank you. The combo update seems to have done the trick. Just to be thorough I did try removing CCleaner first, but it made no difference. (I used it to try and delete the Safari cache without also losing the cookies, as that means having to sign in at a number of sites.) However, that combo update was just the ticket.

Rather than a crash log, which is likely to be unintelligible except for developers:

Please run Etrecheck and post its full report here. This is longish too. You need to use the "additional text" button and paste the report into the text box:

Hi,

Similar behaviour here. Finder crashing and restarting every three seconds, and relaunching some applications (at some point I had 5 different instances of Firefox and Skype). I was asked for logging in again with my Apple ID (possibly a loss of network connection), but the System Settings icon kept bouncing forever. The system has almost frozen, and there was no way to access the finder menu. No way to send a crash report either (or at least I was not asked for that).

Catalina update done just after release of 10.15.6, thus first time this happens after having the iMac up and running since the update.

My problem was a little different with my 2018 Mac Mini. My machine just got really slow, mouse movement very erratic. I tried to restart, but it said finder was busy with an iOS device - I cannot believe I cannot override that ! So, I used the power button to force it. Three times in one day, the day I updated to 10.15.6, it crashed while I was not in front of it. I got "kernel panic, watchdog expired" each time, which sounds like a hardware problem. I reverted to 10.15.5, and as hoped for everything is fine now. I am not aware of any updates in 15.6 that would help me. So, I am now set to manual update, not sure when I will try updating again.

I have a similar problemwith 15.6 update the first time the iMac (13.1 Model) crashed. the second attempt after restoring 15.5 and all my files and apps resulted in freezing of the machine and apps. So have reverted to 15.5 which works well and stopped any future automatic updates

Hi,

Is the 15.6 update compatible for Chrome? I need to use a video platform for work ( Doxy.me) that strongly recommends using the Chrome browser.

From these posts, it looks like this latest 15.6 update has created problems using the Chrome browser? IS this been a problem?

Any suggestions?

I am struggling to add the log as it seems to be too long for the addition text feature. How is this best done?

What worked for me was to download the full update from the Apple website instead of the incremental update you get via the regular update procedure. I provide a link in my post above.
