Hi. Dave from Avatron here. We've been testing on a new MBP and haven't been able to replicate the problem. However we do have a working theory about the cause.
Our theory is that Migration Assistant simply fails to invalidate the kernel extension cache when it should. The result is that when you migrate to a new machine with a different built-in display driver configuration, it can't wake from sleep. Or more precisely, it can't wake to Intel graphics if the last graphics adapter used was the Radeon one.
If we're right, then one of these steps should fix the problem:
1. Install a kext (for example, simply reinstall Air Display), OR
2. Uninstall a kext (this is why the problem went away when you uninstalled Air Display), OR
3. "Touch" the kernel extensions directory in Terminal, OR
4. Boot in Safe Mode.
Then reboot.
If you can't wake from sleep, please try one of these possible solutions, and let us all know how it goes.
Thanks!
