MacBook Pro 210 Degrees Fahrenheit

Actually... that is too hot. Your machine is just below it's thermal threshold which is about 212 F. Extended use at that temp is not a good thing. Is this a sustained temp you're seeing... or is that a high before the fan kicks in to cool it off?

My kid carelessly left Minecraft running overnight on an old iMac several times, and each time I would find it in the morning sounding like a jet plane about to take off. I've never seen a machine get that hot in my life! Even that iMac never did that, even when he left other games running overnight... just for Minecraft. After the last such incident, the iMac died completely. One data point is not exactly scientific, but considering that it's the only Mac I've ever had die of hardware failure in 28 years (except the one I dropped on the floor), I have banned Minecraft permanently from all Macs I own.

Based on Thomas A Reed's comment, I did a quick Google search on the problem. It seems like Minecraft toasts most notebook computers... Mac or PC. It would appear that there is nothing wrong with your machine. It looks like Minecraft simply should not be run on notebooks. Have you tried turning down all the graphics settings to see if things cool down a bit?

It's really quite silly that a game with graphics that probably couldn't even rival Castle Wolfenstein ages ago will use more power and generate more heat than something like BioShock or Half-Life 2. That tells me something about the quality of the code.

Well... unfortunately, I guess that's a result of the massive amounts of cheap storage, inexpensive RAM, and powerful processors we have today. Back in the day (eh-hem), somehow they managed to create addictive games with just a few KB. They had to be super efficient and use just about every trick to be as efficient as possible. Since I grew up using systems with minimal resources, even today... with super high-end components, I still always try to have as few processes running as possible (even though I doubt most of them even make a dent in my performance).

Fortunately, there are still good coders out there, but most don't really have any significant limits on the amount of resources they have available.

If it's behaving normally, probably not. I wouldn't worry about it at this point, although I would definitely be cautious about playing Minecraft. If the machine starts acting weird, a hardware test may be a good idea.

If your Mac computer overheats, it's either defective, or it's Apple's software's fault. The hardware driver should never allow the computer to execute program instructions that allow it to overheat. You should be reporting this to Apple's tech support ANY time your machine overheats and provide details about how to reproduce the problem, so Apple hardware and software engineers can patch the OS and drivers to where it can't happen anymore.
