can I erase my only internal hard drive?
I have installed macOS Sonoma on an external drive and set it as the boot drive because my internal Macintosh HD hard drive ran out of room. Can I erase that drive now? If I make enough room on my internal hard drive, perhaps I can install macOS Sonoma to that drive again and do other things to keep it from filling up, like setting certain files on an external hard drive. Is there anything else I can do?
Mac Pro, macOS 14.7
