Use the Apple USB Ethernet adaptor. Search for "USB Ethernet" at the Apple store http://store.apple.com Early startup debugging is either with a prototype with extra hardware inserted, or with an In-Target Probe (ITP), most likely the latter. _______________________________________________ Do not post admin requests to the list.

Knowing that it's sparse isn't enough though; you'd then have to look at the image itself (not sure of O_EXCL is being used), and look at the header on it, and see if the "encrypted" bit is being set or not. This doesn't reliably determine whether the image is used to host a FileVault user's home folder. In fact, I use encrypted sparse images all the time when handling sensitive source code: the encryption is a requirement, and the "sparse" option is for convenience (when working with fixed-sized images, I usually run out of disc space sooner or later). The OP will have to look for a different way to find out what he is looking for... This email sent to site_archiver(a)lists.apple.com
