Not enough space for system upgrade / Delete "Other Volumes" in macOS Big Sur

Hi,


I am trying to reinstall the latest version of macOS but couldn't because I only have 13GB of space left.


We can see that "Other Volumes" is taking a huge space, 104GB. I tried to delete/erase, none of these functions are working.


I did not use this computer for 2 years, bought in 2019. Since I am trying to sell it, I erased everything and reinstalled Big Sur. I prefer installing the latest version before giving to someone else.


I did erase and reinstall MacBook few times in the past but never encountered such issue.


Your help would be much appreciated if someone can tell me what to do. "Erase and Volume -" are both not functioning, appears to be grey. I did reinstall Big Sur twice already, erased everything before doing so. Still having the same issue.


Thank you!

MacBook Pro (2017 – 2020)

There issue appears to that the User has 3 Macintosh HD - Data Volumes


The First Macintosh HD - Data Volume is showing /System/Volumes/Data. This is the One to Keep


Suggestion to Click the Second Macintosh HD - Data volume and check for the Mount Point appearing on the right side of Disk Utilities


It will probably show /Volume/Macintosh HD-Data


Do the same for the Third Macintosh HD - Data


If correct and the 2nd and 3rd Macintosh HD-Data do show as /Volume/Macintosh HD-Data they need to be removed


Very careful now and make user to choose the Second Macintosh HD -Data Volume and use he Minus - sign to remove that volume


Repeat for the Third Macintosh HD -Data Volume
