Hi,
I just get a fancy iMac7,1 (2007) and would like to switch my desktop to FreeBSD. I'm usually on Linux and have some experience using OpenBSD. Unfortunately, even installation already fails. I used FreeBSD-12.2-RELEASE-amd64-memstick.img (tried 11.4 also, with same behavior). I get the boot menu and right after the kernel has been loaded - I think, when the display switches to the framebuffer - the display gets unreadable (every display line is shifted somehow). I can do a reboot using Strg+Alt+Del, but installing the system is not possible, because the screen output is unreadable. The iMac has a AMD ATI RV630/M76 VGA card.
Can you give me any hints on this issue? E. g., how to switch off the framebuffer?
Thanks in advance,
Martin
