How can I remove partitions in a 2017 Macbook Air?
My 2017 Macbook Air with 128 Gig storage froze when I tried to install Big Sur, so I tried to restore it the original Mojave version with my Time Machine Backup. I ended up with it having three partitions in the 121 Gig container that does not show up in Disk Utility. How can I get rid of those partitions so I can restore the Mojave disk from Time Machine?
MacBook Air 13″, macOS 10.14
