I cannot find my photos in iPhoto, since the app is not support in this OS version, anyone can help?

You need to transition to Photos which replaced iPhoto 6 years ago.

Launch Photos with the option key held down. From the dialog, choose your iPhoto Library. Photos will create a new library from your iPhoto media, you iPhoto library will not be changed, though it will be renamed.

That's the Application. It contains no photographs. They're in the iPhoto Library which you would expect to find in the Pictures Folder.

Hi there.

I've just found an old hard drive with the following - iPhoto is 'there' but not accessible. In info it says it has 1.2GB - I would kill to get access to the photos in this! Any hints? If I follow your advice above, it just shows the icon as greyed out, as per below, so there isn't a library to access. I checked 'Show package contents' and can't see a library.

Any help would be appreciated!
