Warning! Upgrade to Catalina 10.15.3 Crashes MacPro (2013) - Will Not Boot !

WARNING!

Just upgraded my MacPro (2013) from Catalina 10.15.2 to 10.15.3.

After the routine download and restart for upgrade installation, the Mac would not boot. Totally crashed.

Now, I'm in the process of a 15 hour restore from my last time machine backup.

I'm not very happy with Apple at the moment, to say the least.

After one hour, still nine hours to go, according to the estimated time remaining.

F'ing Apple..... here is what happens when we upgrade these days!

Thanks for the heads up Neo...

Just updated my iMac to OSX 10.15.3 but not touched my MBP and left it at the final Mojave state.

Me too...

Well, just be careful and if anyone feels they must upgrade (there is actually no compelling reason for most people to upgrade), do make a full backup first.

I broke "my own rule" and my last backup was about a week ago, darn it! I lost some files here and there, but nothing critical.

Mine is a MacPro (2013), maybe you will "get lucky" on a MBP, or maybe NOT.
