Eh, can't really fault Apple for pushing out 32-bit support. It had to be done sometime, and they've already gone 64-bit only with iOS and iPadOS so it made sense for the ecosystem as a whole. It will be a pain for a bit though if you need software to work but also want the new features.
Always bamboozles me, the devs knew this was coming too, right? Weird how a lot of companies that make important software reeeeeeally hate to actually update it. My dad does a lot of financial stuff, he has to work with plugins that still require Internet Explorer ?. Thankfully I mostly work with Excel and other very common stuff that's updated regularly.
This is true, 'tis a nice update. I don't use it much differently than I did Mojave though, but I am pleased with the overhaul to System Preferences. Bit of a learning curve because stuff is in different places, but it's much more consistent with iOS now.
so we now both have eachothers apple id emails in our contacts, yet still he's not receiving?
update: we figured it out. needed some secondary apple id thing on his end. works fine now.
