I know a lot of reviews say Enhanced Edition is awful, but I'm wanting to play NWN on my MacBook Pro. I have the original version of NWN Diamond, but it's PC only. Is it worth purchasing Enhanced Edition over trying to get the original running via a method such as Wine or VMWare (running via those methods makes my MacBook very hot and the fans kick into overdrive)?

The Enhanced Edition is not awful, it's just not very enhanced yet. And some minor bugs need fixing, or may already be fixed, but the downside to the GOG version is that you only have access to the official patches (last one was November 2018, next one might come out in December this year), while on Steam you get access to current development builds, too (which is something like beta patches). Still, the EE works fine and is more or less the same as Diamond. If you think the price is acceptable in exchange for Mac compatibility, I'd say go ahead (especially with the current discount). If you get Darkness over Daggerford or Tyrants of the Moonsea along with it, it's worth it at least for those two EE-exclusive DLCs. I don't have a Mac myself though, so I can't tell you anything about how well it runs on that OS.

Be sure to avoid the upgrade to OSX 10.15 (Catalina), as that will disable 32bit app support.

This update is not yet on GOG (because it's still in the dev branch), but the next stable version will make NWN 64-bit.

If you already own NWN Diamond for Windows and don't want access to anything EE-specfic, it is pretty easy to get up and running using Wineskin. I ran it that way on a 2013 MacBook with no heat problems and little if any fan activity.

I don't know what the status of Wineskin wrappers will be after 32-bit support is dropped, though--all of mine are giving the warning that they need to be updated and I haven't seen new acitivity on the Wineskin home page for quite a while.

Great news
