Hi Greg.
This is certainly reassuring. I had originally tried to install 7.0 (final), but the installer flat out crashed, so I stepped back to 6.1.5 to see if I could get that to work first.I have successfully installed 7.0 (beta, over the summer) on a core duo (not core2) macbook (not pro), in i386 mode, and on acpu0 at mainbus0 apid 0: Intel(R) Core(TM)2 Duo CPU T7500 @ 2.20GHz, id 0x6fbin amd64 mode.
However, I am pretty sure I had GPT issues and ended up zeroing the diskI'm curious what your partition setup was -- did you have to have a standalone partition to hold rEFInd or rEFIt?and using an MBR label, perhaps due to what you are reporting. Running fdisk and gpt show on the amd64 system confirms that. I was just trying to use the machine to test building packages under 7, and I didn't want to dual-boot, so I didn't worry about the gpt issues.
Other than bootblocks, I think netbsd 6 probably and definitely 7 are okAfter much trial and error, I managed to get the above method to work: manually unpacking the sets I needed into the dkN wedge. The current challenge lies in the boot process. Realizing you did not go dual-boot, do you have any suggestions on how to install the boot code? When using installboot I've tried:with gpt labels. So you may be able to create a partition for NetBSD within OS X, and then boot off usb and manually newfs and unpack setes into the dkN wedge that is created from the netbsd gpt partition.Probably you can install the gpt bootblocks, but I'm somewhat unclear onthose.
installboot - /dev/dk3 bootxx_ffsv2Using rEFInd, a disk shows up in the selector, but when I select it it says that no boot volume can be found.
