Can't open numbers docs
Getting "to open this spreadsheet you need latest version of numbers" on my iMac (10.10.5 Yosemite)
Checking compatability I need 10.13 or better. Can't upgrade to mojave my machine is mid 2011.
I'm thinking that because the files were changed on my iPad they've been altered to latest version.
Is there any way to now open them on my mac?
iMac, OS X Yosemite (10.10.5)
