Apple Releases macOS Catalina 10.15.6 Supplemental Update With Virtualization Bug Fix

Either one will install 10.15.6 with the supplemental update included.
A tip that may help: I often compress and save the downloaded install files for future use as it's easier to make a USB Install Drive than redownloading and I like to keep copies of previous OS X releases as Apple removes previous versions after some time. After it downloads and the installation window appears, look for the "Install macOS [name]" file, compress it and save it (of course do this before the installation as the installation file is deleted afterwards). I've kept official OS X releases as far back as 10.6 Snow Leopard.
I hope it does something about this too, i.e. the ”com.apple.driver.watchdog” related panic:
Constant Kernel Panics – userspace watchdog timeout: no successful checkins from com.apple.WindowServer
I have it installed, but don't let it start on boot, and don't run it normally. Same KPs on a 2014 MBP and 2012 Mac Mini on 10.5.6. I have another 2017 MBP on 10.5.5 that does not seem to be experiencing the same issues, running 90% of the time with VMWare and External displays hooked up.forums.macrumors.com
Doesn't seem to. Had that yesterday morning. macOS took minutes to try and wake from sleep, briefly showed something, then eventually gave up and showed the grey screen of death. After reboot, a panic with a watchdog timeout, blaming WindowServer.
Yeah, I know – same thing happening here still from time when attempting to wake from sleep.
My 16-inch MBP is now back in "repair" having only come out of repair on Friday just gone. With a new logic board.
Apple said they need a diagnosis of hardware issue AGAIN before they can replace or refund me.
I have again demonstrated this in front of staff in the store (authorised reseller as there are no Apple stores in Ireland where I live).
I have also sent in videos and photos of constant KPs since I started using it on Saturday.
I have 2 customer relations people on this case now. I am not accepting it.
Either the 4000USD machine is stable or refund me.
