Another option is Disk Copy 4.2 if the images are still in the older format. For some reason Disk Copy 6.3 is really flaky with making 800k disks.

Since you have a Mac, the sea.bin files on Apple's site shouldn't be a problem. They are self extracting images that are in Disk Copy 4.2 format if I recall.

Also ADTPro with 2IMG format images works really well. No need to mess with Apple's Mac specific image format (or resource forks!) and 2IMG copies of GS/OS installer disks is easy to find.

You only need Disks 1 to 6. The Apple II Setup disk is for Appleshare servers.
