A look at the Mac through linux eyes...
Linux Box Admin takes a look
and finds a few interesting things.
What I only recently learned personally, is that many, many Windows and linux users have problems when they first meet disk image files that are so common in the Macintosh world. A short explanation for outsiders: Disk images (.dmg, .img, .smi) are similar to ISOs and are supported by the system, so that you double-click them and they're mounted in the filesystem. Most applications for Mac OS X come as .dmg-files. You double-click them, copy the contents to the Applications folder and unmount the disk image again. Afterwards you can archive or delete the disk image file, since the application has been installed already through the copying process. On first run, an application will create its preference file(s) etc. (Wow, now I can point those forum users with problems with disk images here. Great!)
