Apple just released a new Supplemental for macOS Catalina 10.15.4!
Included with this update is a new Full installer.app, BridgeOS, Combo and Delta Updates.
Discovered another issue with the 10.15.4 supplemental update. The contents of /Library/Logs is being altered by the update. This includes Sophos log history which is now gone, @marc_grubb . We also use this directory to record several log files related to management operations we perform. That directory looks like its basically reset to default now with all log files gone. Hey, that ain't cool Apple to our log files and other data with an update. What else is being impacted without our knowledge?
@bryantdresher @gachowski Thanks for posting that, I just confirmed the Computer Name and the Host Name are getting reset back to default after the Catalina 10.15.4 Supplemental Update! Time to write another article :
Also thank you for posting the link about the logs @sdagley. Sadly this confirms that the logs are getting blown away 2 updates later :(
@danny.gutman Do you set the Computer Name value with a configuration profile ? Maybe the profile is protecting it from the change. I think everyone else is setting it with a scutil and a script.
Applied the 10.15.4 Supplemental Update to a test laptop a couple days ago.
Didn't see a change in
HostName, but yea confirming that
/private/var/log/ directory definitely got purged.
Opening a ticket with Jamf since either/both of those issues would impact our environment, the second might just piss off our Security team (even if unified logging is a thing).
This morning I had a full machine lockup. I assume this is what @wmehilos may have experienced. Startup apps stayed in a bouncing state. It occurred in both my standard and Admin profiles. Apps were okay in Safe Mode.
If the App managed to open, they would usually flicker constantly (contained to just the app):
I "resolved" this by booting into recovery and running first aid. (I got a Kernel panic later today, but I believe it is unrelated)

I was on the 10.15.4 build from 3/25/20
I updated to the supplemental update (19E287) through the Software Update section in System Preferences on 4/12/20
I'm hoping they patch this soon, but I plan on holding off on 10.15.4 in my environment.
Found this post after searching for "computer name change after 10.15.4 supplemental update". I don't use jamF, but wanted to chip in here to let you know that I just updated my computer with the 10.15.4 supplemental update and the ComputerName did change back to the computer model, MacBook Pro, instead of our asset number format it had prior.
Computer is not connected to AD, is managed by MDM (not jamF) and Apple School Manager.
Yes, I can confirm this on all machines that have taken 10.15.5. Literally dumbfounded… At Apple, quality has fallen off the edge. Seriously, Unicode delayed updates to new emojis; fix the bugs that matter. If it sounds like I'm frustrated, your senses are working. Please work with us and understand the pain you (Apple) are causing.
Also wanted to say - this is in no way JAMF related. My final test was on a clean internet recovery imaged machine, not AD joined - just named. It was not a DEP machine and it was not enrolled in the JAMF Pro server. I built it some weeks ago and it had 10.15.4 on it. I ran the available update and the update it installed was 10.15.5. Before the reboot I checked the name and it was correct. I watched the machine using ARD and its name changed to "iMac" during the restart process where it finishes the update - ARD reports the machine name when connected.
I probably should add that the machines in question were not new and are iMac's. An example one is iMac (21.5-inch, Late 2015)
Here's another example:
Macbook Air (11inch Mid 2012)
2 GHz Dual Core Intel i7
ran the available update - Mac OS Catalina 10.15.5 update
Now it's on 10.15.5 (19F101) and after the update the machines name has changed and now is called "Macbook Air"
This is a totally unmanaged Mac
