The solution was to disable 3D acceleration in VMWare by unchecking the "Accelerate 3D Graphics" under Settings... options for the virtual machine.
This solved the issue not only for the 2010 Mac Mini, but also for a 2011 27" iMac.
This solved the issue not only for Roller Coaster Tycoon (original), but also with Corkscrew Follies, and the Deluxe edition.
I think an in game day is an hour in real time. Pretty sure there's 3 bank deposits per in game day, and they're 20 real minutes apart. That'd be an hour.
Some missions seemed to skip me ahead in time, though I'm not sure about this, I've only played it through once. I know when I let a captain get away, I'd just go play some story missions until he came back. You do get a message when they return, as the fella above said.
To stop captains getting away, I think it's best to take over the entire roof area around them. Kill every guard with assassin's signals, knives or crossbow(without being seen). Then stay on the roof until you've found him with eagle vision, and can get a clear shot with the hidden gun. Most guards run away after you kill him, so it doesn't matter that they hear the shot. Don't forget to search the captains body too, they have a good haul.
If you're still having trouble, you might consider saving the game before atempting to kill a captain, then reloading if you fail. Though I think you should be alright if you kill every roof guard and just be patient.
Edit - I tried to edit this last week, but it seems it wasn't accepted by peer review or however it works...anyway, when you want to save the game, just check your assassin pigeons, or craft bombs, or buy something. The auto save goes off whenever you do anything, pretty much. So just take advantage of that.

According to the Steam page for this game, it is not compatible for Windows 10, and there's no telling if it will ever be. Ubisoft likely doesn't care that much.

Perhaps try running the application in compatibility mode for Windows 7. To do so, find the AC-Revelations folder in your Steamapps location, then:
And try it again. If this does not work, @pushasha's comments may work. Otherwise, there may simply be no hope, as compatibility to Windows 10 is tricky.
