Editing or managing?
Mainly managing but with a bit of editing occasionally !
Anything in paticular you do not like about iPhoto?
Is iPhoto not enough? The library can be stored on a network drive.
I personally am very fond of Lightroom, but there is alsp Aperture.
And the best is depending on your needs and how you think.
There have also been dozens of threads about the "best photo management software", maybe you can find some.
Working with iphoto '09 on my desktop and iPhoto '11 on my mac book pro. Tried to change libraries on my macbook pro to my network drive where I had copied all my iPhoto library (ex desktop) but it would not work. '09 and '11 have a different folder set up. I have read changing to '11 from '09 is a nightmare !😱
Do not want any hassles.
I upgraded from '09 to '11 without issue, but of course there is always the potential for problems. It would be easy enough to copy all your picture masters to your network drive, not your library the masters, upgrade and if the library became corrupted just import the masters into a new library. If the upgrade went well, just delete the master copies.
