So it should look like this under Bluetooth Devices? Does CAT activate Bluetooth for me?
EDIT: So I disabled SIP so I could try to run CAT. When I started the tool, it informed me that Continuity is already activated on my device. Lo and behold, it handoff is available in settings. I'm going to sign in and out of iCloud accounts and see if I can confirm it's working or not.
