Allow A USB Roaster On macOS
Summary
On a Mac laptop with Apple silicon (macOS 13 Ventura or later), macOS asks you to approve a new USB accessory before any app can use it. Until it is allowed, the roaster can be plugged in and switched on while Rostoc still cannot talk to it. Approving it takes a moment: with the Mac unlocked, unplug the roaster's USB cable, plug it back in, and choose Allow when macOS asks. For an Aillio Bullet, Rostoc says this itself. From Rostoc 0.4.8 its waiting banner reads "Your Mac has not allowed your … yet. Unplug it, plug it back in, and choose Allow when your Mac asks.", and Rostoc connects by itself once it is allowed. A failed connection can also say "macOS can see the Aillio Bullet but has not allowed apps to use it."
Steps
- Unlock your Mac. macOS will not approve an accessory while the Mac is locked.
- Unplug the roaster's USB cable from the Mac, wait a few seconds, and plug it back in.
- If macOS asks whether to allow the accessory to connect, choose Allow.
- If nothing asks, open System Settings, then Privacy & Security, and find Allow accessories to connect (on newer macOS versions it sits under Accessories). Choose Ask for new accessories or Automatically allow when unlocked, then unplug and replug the cable again.
- Connect again in Rostoc. If the roaster is still not found, work through the USB cable and port checks.
