I have macOS High Sierra and macOS Catalina software update isn't showing as a software update for my Mac. I've checked pending downloads, checked my computer for software updates, but not sure what I can do get the new software. Any ideas on how to get the update when it's not showing in my App store?
MacBook Air 13", macOS 10.13
I mentioned in my post that the "update" (the term that is used by Apple btw. See screenshot below) wasn't showing up in my App store. Oddly enough you helped me find what I needed so thanks for that.
Going to Catalina (10.15) from High Sierra (10.13) or Mojave (10.14) is not an update, it is referred to an upgrade.
First of all, do not do such an upgrade without a solid backup. Have an up to date Time Machine backup.
And make a full bootable clone of your system drive to a separate hard drive.
To upgrade, just go to the App Store, search for Catalina and click Install.
That is NOT what you want.
This update is for er... updating from 10.15 to 10.15.1.
To upgrade from High Sierra you need to full Catalina installer as I wrote before; it will install 10.15.1 directly.
The first thing is to check whether your machine can take the new OS. macOS Catalina is compatible with these computers
Thanks for replying. I checked that already and it's compatible.
Thanks. I've been through all the Apple Support pages already, including the one you listed.
macOS Catalina software update isn't showing as a software update for my Mac, why?
