Hi. I haven't been able to find anything about this update here, which has been out for quite a while. Anyone who applied it and is it safe to do? Running Clover here.

Yes, I applied it to my Catalina installation successfully by using the standalone update downloaded from Apple's support site :
Security Update 2021-003 Catalina

Actually I installed it on one machine and then use SuperDuper to clone the completed installation to my other machines.

I've been trying to install 2021-003 and there's no way. It keeps installing and at reboot does nothing and goes back to normal. I bugs me to see that 1 on the System Preferences icon
