OS X: Can't use an actual CD directly #19

Closed rakslice closed 4 years ago

rakslice commented 4 years ago

In OS X, B2/SS can't use a disc directly in the optical drive. I tried explicitly adding its /dev/disk* device to the volumes list but this did not make any difference.

To verify there wasn't an issue with the disk contents, I used OS X's Disk Utility to take an image of the CD (i.e. in DMG format), then opened the image in OS X and unmounted (but not ejected) it in Disk Utility, and then added the /dev/disk* device for the mounted disk image to the volumes list in the emulator. This read from the image without issue, and even booted from a bootable one.

Because the owner/group is different.

an actual CD: br--r----- root operator /dev/disk?s1

an image CD: br--r----- you staff /dev/disk?s1

You can mount an actual CD by doing:

$ dscl . append /Groups/operator GroupMembership you

Okay.

What I had done is that I temporarily gave my user access to /dev/disk? by changing its permissions but not the corresponding /dev/disk?s1.
