Pages problems between iPad and iMac
My friend created a document on his iPad using Pages v2.5.3. He sent it to me as an email attachment. I could open it on my iPad however I could not open it on my iMac running Pages '09 v4.3.
I got the error message pictured below. Is the problem at his end or mine? And how do we correct it?
I am running Mac OS 10.8.5 and Pages '09 v4.3
He is using an iPad iOS 8 and Pages v2.5.3
iMac, OS X Mountain Lion (10.8.2)
