Hello there!

Today I update my Macbook Pro to Catalina, but after realising that I can't get files from my Samsung SSD and can't to few other features, I try to downgrade to Mojave again.

The downgrade method I read was through a Time Machine, but after an hour of recovering my stuff, there was an error window that says "An Error Occurred Restoring from Backup".

After that I try to reinstall my mac os, but I can't do it anymore, because I have no space left on my macintosh hd (only 300mb free space, before all of this there were a 50gb of free space).

What should I do? What is the best way to get back to my files? To delete everything on macintosh hd via disk utility and then try to get back all of the stuff from Migration Assistant, or is there any better ways to do this?

Thanks!

Have you reformatted the internal disk of the MacBook? “Macintosh HD” is no longer a singular partition, but an APFS volume group (alongside Macintosh HD – Data). You have to format either the entire APFS container or the whole partitioning scheme to reclaim the space. Afterwards you can restore Time Machine.
