I’ve never been in tech professionally, I’m a truck driver (now working in the office of company but still drive sometimes) but I have always been into tech. I selfhost as much as possible. Bitwarden, jellyfin, seafile, etc. and also run a Lemmy instance. I like tech projects and control.
Fedora has always had good Mac support in my experience. Should just be able to hold option key at boot and select the USB.
If you want to continue dual booting I’d use the Mac’s recovery mode to shrink the partition so it leaves space first. Other than that it should be just like normal. Hold option to get the boot menu.
