Buying a maxed out MacBook Pro seems like the most expensive way to go about getting the necessary compute. Apple is notorious for overcharging for hardware, especially on ram. I bet you could build a stationary tower for half the price with comparable hardware specs. And unless I'm missing something you should be able to run these things on Linux.

Also, if you think Apple’s RAM prices are crazy… you might be surprised at what current DDR5 pricing is today. The $800 that Apple charges to upgrade a MBP from 64-128GB is the current price of 64GB desktop DDR5-6000. Which is actually slower memory than the 8533 MT/s memory you’re getting in the MacBook.
