Two hard drives in restored Mojave – HELP!

[rediffusion]

Yesterday I updated my MBP to Catalina and immediately disliked it. I decided to revert back to Mojave using Time Machine. After I had done this and restarted my computer I now appear to have two hard drives – see below.
The first time I did the Time Machine the restore file, so I did it again – which worked.

My question is... how do I fix this? Has Catalina caused this problem or was it the failed restore.

Many thanks in advance.

Bumping this one in hope of some advice. Many thanks!

Neither. As documented, Catalina splits your HD into a read/only partition, where it puts the system, and a read/write partition, where it puts your data. You didn't clean this up, so you still have two partitions.

Thanks for your reply. I worked it out last night and deleted the partition that Catalina had created. Everything is now good having reverted back to Mojave.

See my post here for my main problem with Catalina. There were many others too (see the rest of that thread)

I have not tried to revert myself, but here is a quick Google search that might help:

Nevermind :
It seems the OP worked it out and posted the outcome while I was getting the Google search.
