I had upgraded to Mojave awhile back and my computer was sooooooo slow so i decided to do a clean install. It took a long time but i backed up everything and was ready to make the USB boot install (which i thought was the best and possibly only way to do it.) When i went to format the USB drive however, the only option was APFS, not MacOS Extended (Journaled). is it ok to us APFS for the USB drive? If not, how can i format it with MacOS Extended (Journaled)? (my computer is running Mojave right now.)
