iMac Mid 2011 Stopped Working
Hackmodford opened this issue · comments
Handoff working in Yosemite without any patches. I just replaced the wifi/bluetooth card inside.
In El Capitan, system report still says Handoff is supported but I cannot get it to work.
I ran the OS X Continuity Activation Tool 2.1.2 and did the diagnostics run and got this:

Did something change in El Capitan? Any suggestions?
Well. The main change in El Cap the CAT is sensitive for is SIP (System Integrity Protection). Which is STILL enabled in your system. IMHO please learn basic for CAT before installing.
But should disabling SIP and this tool even be necessary? It was working in Yosemite without making any software changes whatsoever, the only thing I changed was replacing the wifi/bluetooth card.
The chart says that I only need to replace my hardware, no software changes necessary.
@Hackmodford 10.11 added SystemParameters.plist - you need to edit that file and set your Board ID to allow Continuity. You can do it booted from Recovery HD or any other boot disk (the file is in /System/Library/Frameworks/IOBluetooth.framework/Versions/A/....)
At least for my Mac, I did not have to disable/re-enable SIP; and I did the edit using vi. YMMV.
From what I've seen, contitool should be able to make that edit for you (but, obviously, not when you're booted from the system you're trying to edit when SIP is on)
The newest version of CAT (2.1.4) should fix this.
You need to have SIP disabled before running CAT, you can enable it later after verifying that Continuity works as expected.
Confirmed, this fixed the issue.
