The problem is the FreeBSD boot loader does not switch the Mac's screen from graphical to text mode so you can see anything. It silently bo= oks in the background. A while ago Rafael Esp=C3=ADndola emailed patches in this thread: http://www.mail-archive.com/freebsd-current@freebsd.org/msg155044.html I tried it and was successful at getting the boot loader to switch to text = mode so I could see what was going on. The kernel stopped printing to the screen shortly after it started booting, only printing EFI framebuffer information then stopping. That is probably a different issue. I was able to get a se= rial login by modifying USB media to spawn a terminal on a USB serial adapter, s= o I could tell the system was actually running silently (also based on disk activity). --=20 You are receiving this mail because: You are the assignee for the bug.=
