Q: Can't access photos on backup copy of Snow Leopard version iPhoto on my Mavericks equipped new MBPr; "no permissions" How to gain access?

I appreciate that response; however, in my case, I have transfered two sets of photos. Each one from a different iMac that runs Snow Leopard.

Using my Mavericks MBPr, I cannot see the contents of these two different folders that now are in an external hard drive.

I haven't imported them using iPhoto, because I wanted to avoid importing lots of duplicates.

Using the MBPr, when I tried to view the contents of the folders, the two folders have a red minus sign on them. When I try to open them, a message says I have no access, because I do not have permissions.

What's interesting is that using one of the iMacs, it has access to the content of the folders!

I tried repairing permissions on the MBP, but nothing changed.

Yes, this worked fine!

Get info---click lock to unlock-----click + sign------add Administrators

Then I had access.

Thanks
