"Unsupported Library" error message

I have a Macbook and a Macbook Air. I have Photos on both machines--recently upgraded to Yosemite on both within the last week.


I keep my photos on an external portable hard drive. I created a Photos library of photos from iPhoto on Macbook. Then I took that same external hard drive, with the new Photos library, and tried to open it on my MacBook Air and I received this notice:

Unsupported Library

The Library "Photos Library on hard drive" is from a newer version of Photos. Please upgrade to open this library.


I don't see anyplace to upgrade my version of photos.


Any thoughts or advice would be appreciated.


Thanks!

John.

MacBook Air, OS X Mavericks (10.9.4)
