FYI: LegbaCore's Apple Thunderbolt-to-Ethernet Option ROM checker was released 5 days ago (I just found out today). If you have a modern Apple, you need this tool. http://firmwaresecurity.com/2015/08/12/interview-with-legbacore-and-their-op... https://github.com/legbacore/t2e_integrity_check Also boot a Linux liveCD (like LUV-live) with CHIPSEC to grab your Mac's ROMs, so you can examine them with (CHIPSEC, UEFITool, UEFI Firmware Parser, etc.). Save the snapshots of the images over time, so you can diff them for changes (with BIOS Diff, etc.). Thanks, Lee RSS: http://firmwaresecurity.com/feed
