My Dell Mini 9 arrived today (last of the lot?) and I fairly easily installed Mac OS X this afternoon, using the DellEFI 1.1 (I had prepared my USB Sticks in advance and had not realised that EFI 1.2 had come out).
Without thinking I installed the 10.5.7 update, and am now experiencing the same video glitch that many many other people are reporting in the Mac OS X > 10.5.7 is here... thread.
I know that the answer to my problem is posted in there - everyone says "boot into safe mode using -x at the boot" (if using EFI 1.1) - but I can't find anyone who has actually described exactly how you do that - what do you type, where, when? I don't get a prompt at which I can do that at any point. It sounds like EFI 1.2 is easier, and you just press shift during boot.
If I can't fix this, I will probably do a reinstall with 1.2, but would prefer the easy option if that's possible - any help greatly appreciated! Thanks.
