It's very easy to network the two systems together, provided you know or able to do a little network troubleshooting and assigning IP addresses as necessary. (Most of the time, IP addresses are assigned dynamically, but some things I want a fixed addresses -- network drives, printers, etc.)
I work on Windows, my wife -- a graphic designer, has used Macs for years (though has no issues on a PC). I have a desktop (Ethernet) a laptop (wifi) and my wife has a desktop (Ethernet), and we both have iPhones. Throughout the house we have multiple other devices. We have four network printers in the office -- two via Ethernet, two via wifi.
For data networking, we have two NAS drives (from Synology) on which we keep both work and personal files we want to share. (For us, things like Dropbox, etc. are kludgy for ordinary day to day work. I do use OneDrive for files that I need both in the office and when I'm out on a shoot.) All this work pretty seamlessly, partially because our router is easy to manage. Almost two years ago I replaced our old router and two repeaters with Netgear's Orbi mesh router. Best thing I did. Not only is it easy to manage (on a computer, with my phone etc.) should I need to do anything, but speed of downloads and upload improved dramatically throughout the house, especially streaming movies.
Hope this helps, though you've had a lot of good advice.
