Hello,
My internal SDD failed last weekend and I've had a lot of issues getting my iMac 2015 up and running using an external SDD, coming across quite a few issues with this model that I didn't previously have.
The last remaining issue I have - Bluetooth takes around 10 minutes after login to turn on. It's off when I boot up, I turn it on and it spins for around 10 minutes then comes on and works without any issues. On every boot up.
Going into bluetooth in system report is empty, however the bluetooth adapter shows in USB as 'Bluetooth USB Host Controller' and reports back fine, identifying it correctly. Going into the bluetooth details using option and command on the bluetooth symbol it shows as blank and 'Address: Null'
Due to the SSD issue I had to revert to older MacOS versions and it works all the way up to Monterey when this problem starts, I've installed Ventura and Somona via Opencore and get the exact same problem. I never had this issue before I switched to using an external SSD, it isn't a hardware issue as it works fine after it turns on and is fine in older MacOS versions.
I haven't been able to find a solution or know where else to look, the logs in console don't show much or any errors that seem to replace to this. I've done the SMC/PV ram reset stuff. I've reinstalled about 12 different versions of MacOS and completely reformatted the drives and started off from scratch and always this issue from Monterey or above.
