Lately, I had Ubuntu in dual boot on an 82 GB partition and macOS on a 162 GB partition. After removing Ubuntu, I attempted to merge these partitions using Disk Utility, but I keep encountering persistent errors like "Operation failed..." "An internal state error occurred."
Okay, I got it I can still the 82 GB volume as partition like people use in windows but I don't wanna do that I want a single volume with all 245 GB storage.
Currently there's nothing in my 82 GB volume and macOS is installed in 162 GB volume.
I've already reached out to Apple Support and reinstalled macOS twice, but the problem persists. Any advice on how to resolve this?
