Air Drop Failure between 2023 MacPro and iMac
Air Drop not working between 2023 MacPro OS 26.6.2 and iMac OS Sequoia
iMac (2017 – 2020)
Hi,AirDrop compatibility issues between macOS Tahoe 26.6.2 and macOS Sequoia 15 are frequently caused by Bluetooth daemon synchronization glitches or mismatched discovery states. Because Apple adjusted its version numbering system to jump from version 15 directly to version 26 to align its ecosystem, cross-generation file transfers often experience communication handshake drops.
Try to Clear the Bluetooth Stack with Terminal.app.
1) Open the Terminal app (found via Spotlight or Utilities) on your Mac Pro.
2) Paste the following command and hit Enter: sudo pkill bluetoothd.
3) Type in your Mac's password and restart the computer.
