How to revert back to an older version of iPhoto
I have an older Mac containing a Snow Leopard partition with a number of iPhoto Libraries, version 5. I installed iPhoto 6 on this partition and it did a terrible job of upgrading the first iPhoto Library that I opened.
Unfortunately, iPhoto 5 will no longer run even though it still exists on this partition.( I find that to be strange because on a different Mac I have 2 different, later versions of iPhoto co-existing nicely.)
Question: How do I uninstall iPhoto 6 so that I can continue to run iPhoto 5 when booted into the Snow Leopard partiton?
