Mojave Security Update 2020-001

[jbarley]

Just finished a successful install of this update on my MacPro4,1>5,1 Mojave HFS system.

I also have it running on my flashed 4,1 (APFS).

It wouldn't install for me through Software Update on a 2019 iMac. Kept giving me ERROR_7E7AEE96CA and forcing me to restart. I downloaded the 2020-001 update installer directly from Apple and was able to install it manually.

For those like me, who have a slow internet connection and several Macs to update, the link to the Security Update 2020-001 on Apple’s servers is...

Well, it only brought me to the "an update is required to use this startup disk" death screen once, followed by 5 minutes of not being able to power up the machine, and finally to a stage where it would boot fine just not with an egpu attached. Perfect start of 2020 I see.

This is with the 2018 Mac mini btw.

update 20200207: resetting nvram fixed the egpu "boot to black screen" problem for me.

Installed on 2/1 with no issues.
Took about 45 minutes to download and install and consumed about 1 GB of disk space. I always download anything large (GB) from Apple EARLY (5:00 am EST) because their servers get progressively slower as the day goes on, as in slows to a crawl. ?

I installed this morning, and now I get lots of "This file is damaged and should be thrown into the Trash."

That's the message for a download of a new application from the developer's website.
It's also the message when I double-click the data file of my bookkeeping software Banktivity. (That'll make you sweat!) I keep many versions of that file, and I was able to open the application and then open the data file successfully.

Thus the issue seems to have to do with MacOS's mapping between documents and applications, perhaps?

I have TechTool Pro, but I'm not even sure which operation to run in there to fix what the Security Update seems to have broken.

I noticed after updating Safari, it became VERY slow on start up.
sheesh.

It refused to install in my Mojave HFS+ inner MacHD requesting an APFS volume.
I installed it in my APFS clone external drive and am cloning it back to my inner drive.
I hope it will make no problems.
Otherwise I will skip this security update since keeping my inner drive in HFS+ is much more important to me.

P.S. The installation worked through cloning to and back as described above and I did not found any problem afterwards.

Installed this on a 2009 Firmware updated MacPro 4,1=>5,1 and got stuck on boot for over 12 hours on 02/01/2019 finally rebooted and wouldn't start up. PRAM reset with removal of all non-system drives got me back in two weeks later got prompted to install it again. =(

Anyone else? Might skip this update since I pan to migrate to 10.15 in a couple of weeks.

I managed to install it but first in an APFS clone as explained in my post. However it was a End 2013 MP and not your MP.
My humble advise: before going to 10.15 make a bootable clone of your present OS. You might be glad to be able to go back...

Updated this morning. One of the weirdest updates I observed by Apple. It took about 20-30 minutes with my display screen going blank and then the progress bar and then blank again. It finally restarted.
