I just updated to 10.12.5 and it seems I can't connect to any of my bluetooth devices, sometimes it hangs saying it's connecting other times it says it's connected but isn't, I tried deleting the Bluetooth preferences file with no success, this only just started happening after updating to 10.12.5
Edit: I solved the issue by unplugging and plugging the usb bluetooth and rebooting a few times, I'd still advise caution if you depend on one of these and want to update
