I backed up everything with Time Machine, had a new system installed on my computer, and now I cannot find my photos on iPhoto. It says I cannot install iPhoto on my computer because it is too old, but I cannot even find my photos.

Hello I wanted to get a new operating system on my old Mac.

I bought an external hard drive and backed everything up on Time Machine,

A new operating system was installed but I cannot find my photos.

They told me to drag and drop and not just take everything because otherwise my computer would be full again.

However now I cannot find any of my photos from iPhoto.

They say my new Mac is too new for iPhoto.

But where are all my photos?

Does anyone know?

Thanks
