The Mac is going to duplicate functionality you already have. I assume the lens will give you functionality you don't currently have, so I vote lens.
If you find that you're light in the processing department, I'd sell the MP and the mini and maybe buy an iMac. Or, (I'm ducking as I type this) if you need to do a lot of RAW batch processing, buy a Windows machine and run Lightroom exclusively on it. You can get more cores for less money, and if it's a singular task, it doesn't really matter that it's a Windows machine. JMO.
