Please help! I’m trying to upgrade from 10.15.1 and both .2 and .3 won’t install. I’m wasting time therefore money and I’m concerned about security. I’ve spent a fortune setting things up and I was hoping for a smoother ride from Apple.
iMac Line (2012 and Later)
Startup in Safe Mode and try updating.
If that does not help? You can also download and use the 10.15.3 Combo Update.
