Pages from iWork09 on older Mac and using new Pages doc. on it
I have Pages [iWork09] on my MacPro [main machine] which is older and runs 10.7.5....I have Pages 5.1 on my MacBookPro which is running Mavericks - the problem arises because once I open a Pages doc. in my MBP it becomes a newer version and when I save it back to the MP, I can't open it = I tried to download and install the new Pages on the MP and it won't because it requires ver. 10.9 - but I can't get that on my MP == so what do I do to work with documents worked on the MBP and yet saved to the MP?
Mac Pro, Mac OS X (10.7.5), 17G RAM
