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.

After reading some of the posts in this forum, are you really sure you want to update?
I assume you meant to reply to the OP who is already running Catalina. They just want the latest point release.
Catalina 10.15.3 won’t install on iMac.
