I am unable to upgrade my MBP (2017) with Mojave 10.14.6 to Catalina (10.15)

You’re checking for updates, and Catalina is considered an upgrade.

Updates are fixes and minor changes, and are expected to be compatible.

Upgrades are larger and potentially involve incompatible changes. Catalina is incompatible with any 32-bit apps, and with any 32-bit drivers, too.

If an update has somehow gotten stuck, log out of the Mac App Store and log in again, and try again. If that fails to resolve the stuck-update notification, then boot into Safe Mode, as that will disable various add-ons, and will rebuild various caches, and try checking again. But I’m going to assume you’re correctly (not) seeing an update pending, when already running the most current update.

To upgrade? Back up your Mac, back it up again, check for any lingering 32-bit apps (Go64) as they won’t work, check your key apps, check that your printer and scanner vendor has drivers available, and go to the Mac App Store and download the Catalina upgrade.

Backups are your only (reasonable) path to reverting or recovering, should you encounter a problem with an update or an upgrade.

So trying to download Catalina from the Mac App Store fails?

(Mojave has a second upgrade path available, via Software Update.)

And there’s no Install macOS Catalina.app found in Applications?

But again, I’d also wait for 10.15.1 or 10.15.2 to sort out some of the bugs, too.

And I’d absolutely have a complete backup created prior to the Catalina upgrade.

I’m not at all certain what you’re reporting.

You’ve upgraded your iMac from macOS Mojave 10.14.5 to macOS Catalina 10.15? Okay.

If the Mojave environment was having issues, an upgrade to Catalina may or may not resolve those.

I’m aware of the sleep-wake mess.

I’m not generally inclined to quickly install macOS upgrades. Not on required or must-work Mac systems. Not without some preliminary testing on a “scratch” install or a “scratch” Mac. Don’t test in production.

If you have some Mac systems that do need to be upgraded quickly, get into the developer program and test the betas on non-critical systems.

If past Apple practice holds, Mojave and High Sierra will both be receiving security updates, too.

*sigh*. I am reporting that if I have Mojave 10.14.6 (supplemental update) on a MBP, and I cannot upgrade or update to macOS Catalina -- and its not just me.

So you’ve (also) tried to download Catalina from the Mac App Store, and have failed that way?

If you want something approaching “seamless”, wait for macOS 10.15.1 or 10.15.2, and for the early bugs to be fixed, and for the various app and printer and scanner vendors to update their docs, and release their app and driver updates.

Few (none?) of the macOS upgrades have ever been seamless. Not at first.

My MacBook Pro Retina Mid 2012 is running MOJAVE 10.14.6.

System prefs. indicated an update is ready but when i run software update it keeps telling me that my software is up to date.

I know that catalina is available so why is it not possible for me to update to catalina.

Thanks

I own a MBP (2017) with Mojave 10.14.6 that I upgraded to Catalina (10.15)

But it took 3 tries. be patient and open software updates and click advanced setting and make sure all boxes are checked.
