iphoto library on external hard drive greyed out & unaccessible from iphoto app
Hi
I have a 2007 iMac, with a 2 gb ext hard drive that holds my iphoto library and 3gb airport for Time Machine backups. I upgraded to Yosemite, after upgrading when trying to open the iphoto app, it said that it had to be upgraded and the only options were quit or upgrade. I shut down/restarted a number of times but this kept coming up with my only options. So I clicked upgrade, this took a long time to run and left it overnight its currentlyversion iPhoto 9.6, when it finished the app opens fine but it won't open my iphoto library. I've tried each of the first aid options for repair they run, the app opens but no pics are found, except those from icloud or Facebook. When I look in finder I can see my library on the external hard drive and in backups but when in iPhoto and I 'switch to library' nothing happens or 'import library' it won't open the file its greyed out. If you have any advice or links to guides i should follow to get the pics back through the app that would be great.
Thanks C
