https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=193524 Bug ID: 193524 Summary: Booting native FreeBSD EFI on MacBooks doesn't switch to text mode in loader Product: Base System Version: 11.0-CURRENT Hardware: amd64 OS: Any Status: Needs Triage Severity: Affects Some People Priority: --- Component: misc Assignee: freebsd-bugs@FreeBSD.org Reporter: mcdouga9@egr.msu.edu Now that FreeBSD has EFI support such as for booting from USB storage, you can partially boot a MacBook from it if you hold down Option while powering on or rebooting. 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 books in the background. A while ago Rafael Espíndola 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 serial login by modifying USB media to spawn a terminal on a USB serial adapter, so I could tell the system was actually running silently (also based on disk activity). -- You are receiving this mail because: You are the assignee for the bug.
