Thanks for this great app
I would need to chance my EDID but ran into some problems. Actually I did get it working yesterday, but after I reinstalled Maverics today I can't get it working anymore. I only have one display, internal laptop LCD.
What I did was:
Dumped my EDID with DarwinDumper.
Opened EDID.hex on HexEdit and changed one number, then saved it.
On FixEDID 1.9, loaded edited EDID.hex, changed display type to MacBook Pro display, then make.
Checked info.plist from DisplayMergeNub.kext and it had this EDID
0FFFFFF FFFFFF00 061014A0 00000000 0A160104 A51D1278 026FB1A7 554C9E25 0C505400 00000101 01010101 01010101 01010101 01016432 40B86284 24304060 354059C2 10000019 982140B8 62842430 40603540 59C21000 00190000 00FC0043 6F6C6F72 204C4344 0A202020 00000002 000C49FF 0A3C6429 2D416400 00000026
I changed it to my edited EDID and installed kext with Kext Wizard, rebooted but I still had my original EDID when checked with ioreg -l, also Kext Wizard didn't show DisplayMergeNub in loaded kexts.
I wonder what i'm doing wrong here?
