@CaseySJ Some more Intel Bluetooth notes...
I reported the version issue to the dev and he said it is just the firmware and not a bug in the kext, and that functionality is not impacted.
On closer look, those with a 9560 who did not have the issue were using version 1.0.2 and not 1.0.3 of the kext.
I downgraded to confirm and it fixed the version. 1.0.2 did this:
1. Bluetooth Core Spec is 5.0 (0x9) instead of Unknown (0xA). Same for LMP Version.
2. Older firmware version. 9.256 and not 10.256.
3. 1.0.2 correctly identifies device types. Example being my magic mouse and keyboard on 1.0.3 are Miscellaneous/Unknown.
Code:
---1.0.3---
Magic Keyboard 2:
Major Type: Miscellaneous
Minor Type: Unknown
Magic Mouse 2:
Major Type: Miscellaneous
Minor Type: Unknown
---1.0.2---
Magic Keyboard 2:
Major Type: Peripheral
Minor Type: Keyboard
Magic Mouse 2:
Major Type: Peripheral
Minor Type: Mouse
In addition, on 1.0.3 the AFH Map for the devices is different, looks more generic. Also, the Class of Device is all zeroes, which is probably why the major and minor types are off in 1.0.3.
The firmware from 1.0.2 feels more proper, though who knows if there are bugfixes and performances improvements in the newer firmware that outweigh what appear to just be cosmetic issues.
Worth noting the dev is getting these firmwares from Linux (I do not know which Linux builds he is sourcing from. Some of the files were an exact MD5 match with an Ubuntu Server install I have, others were different). We may find a firmware that better matches our card than what the developer has included. I might try to compile 1.0.3 with the older firmware from 1.0.2 (I will probably gut the firmwares that 9560 doesn't need, because I am running out of room in EFI partition).
I noticed one issue today that I don't know if it was in 1.0.3 or 1.0.2 so I am going back to 1.0.3 to see if it goes away. My AirPlay menu bar item always shows. Yes, you can hide it in all cases, but it's supposed to only show when there are available devices, and there are none in my case.
