[Release] macOS Sequoia 15.0

Please get the latest BluetoolFixup.kext from here or add boot-arg -btlfxbeta and test again. Also, while this isn't your problem, you should add bluetoothExternalDongleFailed and bluetoothInternalControllerInfo to NVRAM > Delete > 7C436110-AB2A-4BBB-A880-FE41995C9F82 in your config.plist. It appears to me as though you retrieved your BluetoolFixup.kext 2.6.9 as a Beta version prior to the Sequoia update. This can be resolved by getting the release version of Bluetoolfixup.kext or adding the Beta boot-arg.
