This reddit discussion contains detailed instructions for using the scripts in this repo. The details are somewhat more in depth than those provided in the README in this repo, for example describing the process of downloading and using psexec (to run regedit with admin privileges) on the Windows side.

Having those instructions integrated here would make this repo more useful, especially to new users and those unfamiliar with Windows, and provide a single authoritative reference.

I can't seem to get this to work in Catalina. I get the message below.

Hi, I notice that this code does not support multiple bluetooth devices yet. I have replaced my wifi adapter in the past for hackintosh purpose. So macOS remembers all the bluetooth device I have. To get the device I am using and also prevent this script from error, I have to select paragraphs of the linkKeys in the original script:
"set linkKeys to paragraphs 2 thru -1 of linkKeys"

I think it would helpful if you can add multi bt device support in the future. Thanks.

I successfully ran the script, but where is the reg file I requested to export? It's not documented anywhere and the script does not tell you after completing.

Like the title says, the registry path listed is empty for me, no entries under /keys

running app/script produced the following error -

Error: /bin/sh: /private/var/folders/75/3wbt116951dbb23vltd8cz180000gn/T/AppTranslocation/031339C1-17F1-424A-B5CD-04361653976F/d/output.txt: Read-only file system

please advise on how to resolve

I can't find /private/var/root/Library/Preferences/com.apple.bluetoothd.plist.

Hi.

Your script won't work on BigSur.
There are no "LinkKeys" in the plist.

Example plist:
{ MagicCloudPairingMasterHint = {length = 16, bytes = 0x4403d3b5169e5473c765485effb30529}; MagicCloudPairingMasterKey = {length = 16, bytes = 0x462d449501ea434587270f34e0070d5f}; SMPCloudLocalNonce = {length = 16, bytes = 0x220db209e97706dff1bf0d2ac397d4ba}; SMPCloudLocalPrivateKey = {length = 96, bytes = 0x6ce14d11 584a296b 9c2f3c56 635d06f9 ... 3225558f 98d3f754 }; SMPCloudLocalPublicKey = {length = 64, bytes = 0x6ce14d11 584a296b 9c2f3c56 635d06f9 ... 7e9e47fb c372f752 }; SMPDistributionKeys = { "48-d7-05-b3-b3-c6" = { "f7-fb-12-d0-e6-5e" = { Address = {length = 6, bytes = 0xf7fb12d0e65e}; AddressType = 1; EDIV = {length = 2, bytes = 0x293d}; IRK = {length = 16, bytes = 0xcb00f4dc3fdefea2ad3910f2af21f3ad}; LTK = {length = 16, bytes = 0x6a9202ccaa1f7221aab756de2eb797a2}; LTKLength = {length = 1, bytes = 0x10}; MITMProtection = 0; OriginalAddressType = 1; RAND = {length = 8, bytes = 0x91c77c4ed0cb027f}; }; }; }; }

There's also another plist on /Library/Preferences/

{ BluetoothStats = { ClassicConnectionTimeout = 0; CommandTimeouts = 0; CoreDump = 0; HardReset = 0; HardwareError = 0; LongRangeDisconnects = 0; LowEnergy3ETimeout = 4; LowEnergyConnectionTimeout = 1; MediumRangeDisconnects = 0; NearRangeDisconnects = 0; SlowEnqueueData = 0; SlowEnqueueDataTimeMicroseconds = 0; USBPipeStall = 0; kLowEnergyMICError = 0; }; ControllerPowerState = 1; CoreBluetoothCache = { "26136684-FEE7-4C2E-AAD2-E5CD800320D6" = { DeviceAddress = "f7-fb-12-d0-e6-5e"; DeviceAddressType = 1; ServiceChangedHandle = 65535; ServiceChangedSubscribed = 0; ServiceDiscoveryComplete = 1; Services = {length = 3925, bytes = 0x62706c69 73743030 d4000100 02000300 ... 00000000 00000b95 }; }; }; DeviceCache = { "8c-79-f5-aa-ab-9d" = { ClassOfDevice = 525372; EIRData = {length = 240, bytes = 0x09100100 e8048080 00000d09 5b54565d ... 00000000 00000000 }; LastNameUpdate = "2021-01-02 14:06:44 +0000"; Name = "[TV] TV Sala"; ProductID = 32896; VendorID = 1256; VendorIDSource = 1; }; "f7-fb-12-d0-e6-5e" = { HeySiriEnabled = 0; LMPSubversion = 99; LMPVersion = 7; LastNameUpdate = "2021-01-03 11:23:04 +0000"; LowEnergyPointer = 1; Manufacturer = 89; Name = BluetoothMouse3600; ProductID = 2326; VendorID = 1118; }; }; InsecureDevices = ( ); LEPairedDevices = ( "f7-fb-12-d0-e6-5e" ); PairedDevices = ( "f7-fb-12-d0-e6-5e" ); SystemLowEnergyDevices = ( "26136684-FEE7-4C2E-AAD2-E5CD800320D6" ); }

Thanks for this script! It’s exactly what I needed, but I did encounter a small issue:

In the past this OS install was restored from a time machine backup from another machine, which caused my bluetooth plist to contain multiple bluetooth adapters which completely broke the script.

The solution to this for me was to just delete the plist and reboot, then re-pair all of my devices. After this, only one bluetooth adapter was shown and the script worked fine. Hope this workaround helps someone!

The "Can't get item 2" bug from issue #1 has made a return in macOS Mojave. The symptoms are the exact same as in the previous issue. They persist even after changing the permissions of the relevant folders, which are by default set to only allow the system account access.

Issue #10 suggests using the file /Library/Preferences/com.apple.Bluetooth.plist. While this file exists it does not contain the expected content when converted to xml using plutil (some values partially redacted):

<plist version="1.0">
<dict>
	<key>BluetoothAutoSeekKeyboard</key>
	<true/>
	<key>BluetoothAutoSeekPointingDevice</key>
	<true/>
	<key>HID15msWithHeadsetEnabled</key>
	<false/>
	<key>PersistentPorts</key>
	<dict>
