My older iMac can not view iPhoto albums from my newer macbook pro
I have a great IMac 20" medio 2007 with osx 10.7.5
I tried to upgrade to Mavericks but it doesnt seem to download...It does say machine should be from mid 2007. Not sure when in 2007 this one is from, but the problem is my wife uses it and I use a newer Macbook Pro which has a slightly newer version of IPhoto because it is running mavericks. I want to share our iphoto libraryies via IPLM, but since this has a slightly older version of Iphoto, it wont accept any photos from my macbook pro. If my only option exporting photos from the newer version and losing all metadata, and then importing into the older version? Is there anyway to downgrade my new version back to the same as this (9.4.3)
MacBook Pro (13-inch Early 2011), OS X Mavericks (10.9.1)
