Problem updating macOS from Mojave 10.14.6 to Catalina 10.15.x

Hey! Unfortunately, you're probably going to spend your day updating your mac. Make sure you have enough storage for all of the updates, you're going to have to begin updating from Sierra and make your way up to Catalina! It turns out it's just too high of a jump to go from Capitan to Catalina! https://support.apple.com/en-us/HT208969 here is the link to Apple's sight to get you started on High Sierra ! Hope this helps! If for some reason you can't go straight to High Sierra try getting Sierra first!

HI, new to mac here! So I have a 2017 MacBook Air running 10.11.16. I've tried updating my mac via app store but when I click the "Download" button it stays grey but doesn't begin the download. So I attempted to have my system preferences look for the update but it says my mac is up to date. I downloaded 10.15.1 to try and install but it did not work, I got the same error message as you. I typed in the command and ran system preferences and nothing again. Any help? I attached images for context.

Run this command in the Terminal then reopen System Preferences > Software Update.

sudo softwareupdate --reset-ignored

You're welcome.

I have the exact same problem. Unfortunately, in my case, I ran this command in a Terminal window, restarted the Catalina installer, and I still encounter the same error. Argh.

Sorry, I forgot to mention! You don't have to do anything with the terminal. It's just basic updates! Have fun!
