Big Sur failed, trying to recover my data
So I've connected by computer in target mode to another Mac (which is running Catalina). I can see Macintosh HD - Data but when I click on it, there's no files. I can see on Info however that there's still 120GB or so of data. When I try to unhide files, I see .fseventsd, .Spotlight-V100, and .Trashes.
Any idea how I can access what looks to be my data still in this folder?
I have done disk utility on my computer after Big Sur failed and there didn't seem to be any repairs necessary.
My previous operating system was Mojave, if that makes a difference. Thanks !
