Hey guys, I'm not sure whether this is the correct sub-forum to post my question so sorry if it's not. I have been working on my own (well tweaked uefi firmware) which works in qemu/virtualbox but right now I was planning to test it on some real hardware and I have decided apple mac machines can be a good place to start. There is no much sense in the project itself it is just a hobby of mine. In order to debug my firmware I believe I need to find JTAG/XDP connectors on the apple mac logic board. So before I will start ordering more hardware I would like to ask whether you people can confirm that your apple mac (mac mini > 2010, mac book > 2010 etc. all with intel x64 cpu) have such connectors on the logic board. Thank you for all the answers, if you have some other ideas how to debug the firmware or anything that can help me it would be greatly appreciated.
