Not sure if this is the right thread, but I just wanted to give a tip in case anyone wants to try going from Mojave to Catalina. Which I finally decided to do because aside from a few older 32-bit apps (rip Akaizer
), it seems like compatibility is pretty good. But of course, Apple’s made it near impossible to find the Catalina installer now that Big Sur is out.
After a bunch of looking around, I finally found this and can confirm I’ve gotten the installer (TBD if it actually works, I’m going to restart my computer which is supposed to start the installer after I send this). https://github.com/munki/macadmin-scripts
I just ran the install script with no options, picked the latest catalina item in the choices it prompts, and it did a bunch of downloading and packaging to create a disk image you can click on to start the install process.
Hope this saves anyone who wants to try this time.
EDIT: just use the apple supported ones as mentioned by @robotboot
