Hi, I have recently factory reset my Mac and I have two Macintosh HD-Datas: one is called Macintosh HD - Data and another is called Macintosh HD-Data-Data. What should I do, as I know this is incorrect?
MacBook Pro 13″, macOS 11.0
The Big Sur installer creates a second volume in the APFS container at the start of a new installation, so when you erase and reformat a disk, you need to delete extra volumes using the +/- icons. If you don't, you get the situation you describe.
First, I would make sure to have made a Time Machine backup and a Bootable USB installer, before either starting again by a complete erase/reformat/install, or maybe first try just deleting the redundant volume, which I am guessing is the Data - Data one.
An additional complication I found, is that Disk Utility sometimes does not refresh its display as one might have wanted. Quitting and re-opening it finally showed the actual disk state.
I am guessing the HD - Data one, with the OS "update" snapshot on it, should be just Macintosh HD and the Data - Data one just Data. The present Macintosh HD seems to be the odd one out. But I could be wrong.
Two Macintosh HD-Datas: URGENT
