Note that the original Apple Broadcom bluetooth devices are not RAMUSB devices, and thus do not have the same firmware mechanism. The firmware applied is extracted from the Windows drivers and the functionality should be equal to Windows. It will apply the firmware update to your Broadcom Bluetooth device on every startup / wakeup, identical to the Windows drivers.

The Broadcom Windows driver will upload firmware into the Broadcom Bluetooth device on every startup, however for OS X this functionality is not supported out of the box.īrcmPatchRAM kext is an OS X driver which applies PatchRAM updates for Broadcom RAMUSB based devices. RAMUSB allows the firmware for the device to be updated on-the-fly, however any updates previously applied are lost when shutting down the machine. Most Broadcom USB Bluetooth devices make use of a system called RAMUSB. Note if you have an Apple MacBook/iMac/Mac Pro etc, follow the Mac instructions Although these kexts do not install any firmware (these devices have firmware built-in), they still depend on BrcmPatchRAM/BrcmPatchRAM2.kext.īrcmNonPatchRAM.kext: for 10.10 or earlierīrcmNonPatchRAM2.kext: for 10.11 or later. In testing, best result was obtained if you replace the IOKitPersonalities entry in BrcmFirmwareRepo.kext ist with that of the injector kext (no need for the injector at that point).Īlso, if you have a non-PatchRAM device (or you're not sure), install one of BrcmNonPatchRAM.kext or BrcmNonPatchRAM2.kext, depending on OS X version, never both. as that is the way Clover kext injection is (it does not simulate kext installation perfectly). If you're using the injector from Clover/kexts, the IOProviderClass in the ist for BrcmFirmwareRepo.kext must be changed from 'disabled_IOResources' to 'IOResources'. Optionally, you may remove all the firmwares from BrcmFirmwareRepo.kext/Contents/Resources. This works from either /S/L/E or EFI/Clover/kexts. BrcmFirmwareRepo.kext, while much more memory efficient, cannot be injected as can BrcmFirmwareData.kextĪdvanced users: For custom firmware injectors, install the injector plus BrcmFirmwareRepo.kext. This kext is much more memory efficient than BrcmFirmwareData.kext and is the preferred configuration.īrcmFirmwareData.kext: Most appropriate for EFI/Clover/kexts. Install one of BrcmPatchRAM.kext or BrcmPatchRAM2.kext depending on OS X version, never both.Īlso, install one firmware kext BrcmFirmwareData.kext or BrcmFirmwareRepo.kext, depending on installation location, never both.īrcmFirmwareRepo.kext: Install to /System/Library/Extensions (/Library/Extensions on 10.11 and later).
