Some long overdue follow-up, but I can finally verify that the clover patches to enable Hand-off do indeed work with the Maximus 6 Impact default BCM4352 combo card.
Next stop… swapping the default wifi/bt card for a genuine Apple BCM4360CD to ditch the kext patches and the need for BTFirmWareUploader entirely.
In case anyone missed it, Toleda just pushed a new set of patches (credit to skvo for figuring everything out) to the airport/wireless half mini repo, and it includes new kext patches for the BCM4352 on Yosemite to enable Handoff, as well as fix the ‘third party’ string in system information.
Here’s some quick screenshots showing handoff enabled on my hackintosh using the Asus built-in BCM4352 half-mini wifi card.
Of course, I can’t actually test that handoff is working since I don’t own a modern/recent enough iOS device, but given that bluetooth has worked fine for me pretty much from day one, I’m going to assume that it will work.
I’ll be updating the config.plist downloads on my 10.10 page shortly, but for anyone that can’t wait, just delete any older 5Ghz patch you may have in your config.plist, and here’s three new patches you need to add:
