Q: iwork don't update for ver. 7.0 on second Mac

You mean pages version 6?

Pages 6 requires new os. Very bad.

If you don't have update, it will be because your computer is old to have new os.

What we need to know is what version of OSX are you running on your Mac, and what version of Pages you are trying to DL.

The current version is Pages 6 and requires MacOS Sierra (10.12).

Did you ever have iWork '09 installed on your Mac?

Try switching your System language to English, then trying the App Store.

Change it back afterwards if it works.
