CVE-2020-9859: unc0ver
I updated my 16″ Macbook Pro from 10.15.4 to 10.15.5 from the system preferences 3 days ago….
since then I have frequent kernel panic crashes while working on Final Cut Pro. The worst were 2-3 times within an hour!
Some other users on MacRumor forum said that their kernel panics happened when connecting to external display….
Macbook Pro is not connected to external display.
For the first time, I feel afraid to use my Mac for the kernel panics.
Installed on my iMac yesterday. Now it doesn’t boot. It’s stuck on :
kextd stall[number], (60s): ‘AGPMEnabler’, ‘GFX0’, ‘AppleHDAHardwareConfigDriverLoader’, ‘AppleHDAHardwareConfigDriverLoader’, ‘AppleMikeyDriver’, ‘PNLF’, ‘IOResources’
(Where “number” increments)
This update was forced for me. I was trying to reboot into Bootcamp (via Option key at boot), but this update instead installed itself. Fortunately I haven’t seen any crashes or kernel panics as a result, but I noticed the mention of unCover in the description above. Does that mean the latest jailbreak for iOS is now impossible to apply to my iPhone?
Looks like the Supplemental Update has bought back the Macbook Pro 16 Kernel panic and GPU crashes. Five times in a couple of hours of installing. Stay away from it if possible 🙁
Two Questions: 1.) If you are on Mojave, but just downloaded the 10.15.15 installer a few days ago just to have it ready, does the new available build of the full installer include the SU patch? 2.) Apparently, this did not affect Mojave?
Correct, this security fix was only for 10.15 & 10.13.
The 10.15.5 Full app installer was updated (yesterday) with the security fix included. If you downloaded the 10.15.5 Full installer a few days ago, you will need to apply the supplemental update after.
Thank you. I had downloaded the Catalina installer just to have it sitting in the background for when I’m ready, so I’ll just delete that and redownload so I have the “updated” version 🙂 Appreciate the intel.
This update stalls for me. I think I’m going to stay away from updates for a while lol
