Downgrade Catalina to Mojave

Hello everyone 🙂

A few days ago, I upgraded my macOS to 10.15 Beta. To go back, I tried to restore my Mac trought recovery mode, but when I erased the disk, I can't install macOS Mojave, but only macOS 10.15.


Is there a way to downgrade to macOS Mojave without using a Time machine backup?

Thanks for reading 🙂

Beta software is not an upgrade - you didn't make a backup (Time Machine or otherwise) before installing?

No, i didn't

Thank you! I solved! 🙂

User-centric queries/comments such as this are perhaps best put to AppleCare's public community support forums, Apple's twitter support account and/or Apple’s YouTube Support Channel vs. risking off-topic here in DevForums, thanks and good luck.

I have the same problem. If I do Shift-Option-⌘-R will i need to reinstall the old microsoft office products or will it keep them? We inherited the computer and no longer have the "key" if I have to reinstall. Thank you for any help.
