Apple family sharing from iOS to Mac
Sure you can.

You can set your preferred account as Organiser, with Share my purchases switched on, then invite &amp; add your other account as an Adult (you could set yourself up as a child, but then you'd have to ask yourself permission ;)

From System prefs > iCloud > Manage Family...
First &amp; last are 'me'



One caveat - you need to make sure that the two addresses aren't already associated. I had great difficulty figuring out why adding my second account wouldn't work. It turned out to be [iirc] that each was using the other as the rescue or secondary email address.

As you're setting it up initially you need two devices [or accounts on a Mac] each to be signed into its own account. It took some juggling for me to set this up on a single Mac, but between iPhone &amp; Mac ought to be simpler.

I'm not sure whether doing this will enable the right to the Mac version of an iOS app. It usually wouldn't, but the iWork suite &amp; Apple's own software in general seems a bit of a special case.
