Q: "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)

what format is the EHD (It must be Mac OS extended (journaled) to use for the Photos library) ?

How is it connected to the Mac?

What version of pHotos do you have on each system (Photos 1.0.1 is the latest - it is installed with OS X 10.10.4)

Have you checked, if both your machines are having the same version of Yosemite? Perhaps your MAcBook has already been updated to MacOS X 10.10.4 while your MacBook Air is still on MacOS X 10.10.3? Run software update on both machines.

Thanks, LarryHN.

EHD is formatted correctly. It turns out that my Air did not have the latest update to Yosemite. Updating it fixed the problem.

In your opinion, is it safe to delete my iPhotos library now from my MacBook? I have a duplicate on my EHD, and I have the Photos on my EHD.

Thanks!
John.

John. before you delete the original, test the copy on your MaccBook Air. Try to edit a few photos to check if the originals in the library can be accessed, compare the numbers of photos and the size of the copied package.

Sure but it will not save much space and you might want or need it later - generally it is best to keep it for a while

see Photos saves disk space by sharing images with your iPhoto or Aperture libraries - Apple Support
