Why can't they figure this thing out, seriously? Or is it just me? I switched to a Mac a little over a year ago. I have a Time Capsule that I use for TM backups. Plugged into the TC via USB is an external HD where I keep my iPhoto library. The library used to be in the shared folder on our MB so me and my wife could access it from either of our user accounts. Every once and a while, one of us would open iPhoto but we couldn't enlarge or edit any of the pics. You could see the thumbnails no problem, just couldn't do anything with them. Permissions problem apparently After contacting Apple support, they said we would be better off putting the library on an external HD. Make a disk image and set it to "ignore ownership". I beleive this is the document for it. http://support.apple.com/kb/HT1198 I followed that document to the letter. It worked for a little while and then the all of the sudden the disk image would mount on my or my wife's desktop with the little red line through it, indicating we don't have suffeicient permissions...WTF? Now I don't know why, but the "ignore ownwership" had to continually be re-checked. How did it get un-checked is something i'd like to find out. Now I'm having problems even finding that option at all. I've done a "repair permissions" already in disk utility. Just seems like the whole permissions thing isn't quite there yet in terms of reliability. Anyone having similar issues? Anyone have a solution? Thank you in advance.
