I was able to get Yosemite running well using winch's most recent modification of clover. I run an old Apple Studio display with ADC connector as a second monitor through an ATI Radeon HD 5770 1024. This requires a ADC to Dvi adapter, then a DVI to thunderbolt adapter, and it works great. The one thing that does not work with this are the USB ports on the back of that monitor.
The startup message regarding this error is in the system log:
Code:
The IOUSBFamily is having trouble enumerating a USB device that has been plugged in. It will keep retrying. (Port 1 of Hub at 0x3d000000)
It is not a big deal, but as it is an error I thought I share it with this group of experts.
Appreciate all of your help, this thread is really great!
