I would like to uninstall Ubuntu from my mac because I have some audio issues and I couldn't solve them so I never use Ubuntu.
My question is a very simple one: Can I use Mac's Disk Utility to delete the partitions? Or do I have to use a Ubuntu Bootable USB to delete the partitions using GParted?
I ask this because a long time ago I deleted the USB stick and now I can't manage to create a new one. The computer simply doesn't detect it...
Thank you in advance
