persistent usb disk for MacBook Air (2010)
I was able to create a Ubuntu 12.10 installation disk on a usb stick that will boot my 2010 MacBook Air. At the time I created it (with unetbootin), I made it persistent and included 5 gb storage. The persistence works on a PC - if I boot it up and change the interface, and even add software, the changes show up on the PC. But they don't on the Mac; even the added software doesn't show up as being installed. This is true whether I boot up the usb on my MacBook Air or my iMac.
I suspect that the problem has something to do with the EFI folder that the Mac needs to be able to boot up, but I'm not sophisticated enough to know where to look or what configuration file or grub entry has to be modified to be seen when the Mac boots. Speaking of grub entry, I did create one on the PC to allow persistence by copying the "try Ubuntu" grub entry and modifying it by adding the word "persistence" in the appropriate place. I titled the entry "Ubuntu 12.10 Persistence", and the entry shows up when booting from a PC, but not from the Mac. This is why I think that something in the EFI folder is pointing me to a different grub boot file. Can anyone help me with this?
Main distros: Ubuntu 20.04 and Linux Mint 19.3
