I ran a mac completely off an external for awhile and didn't like it. At the same time, it's nice to have a computer that's completely dedicated to the os. With Mac, you're paying for software, and I do love the OS. After all, inside, it's all the same hardware. I run a lot of games off my imac and it runs them well. That said, imo your BEST option is to get a PC for gaming. That could be a plus for running the OS and the game off the external.

Usb3 will give you up to around 5gigbits/second, thunderbolt 2 will give you 20, thunderbolt 3 will give 40. Earlier mbps would have a Thunderbolt 2, which is still twice as fast as usb3, but not as fast as T3. Rather than trying to run from a usb3 hd, I'd advise getting a thunderbolt 3 enabled hd rather than usb3, but ONLY if your mbp is 2015 or later. So, I kinda like to think I know a little about this. I've also opened and replaced parts on both PC and Mac, so I'm familiar with what's inside. I also have experience with the 2015 MacBookPro because I bought one for my son. I've used windows 7,8 and 10 through bootcamp on both iMacs. I've used Macs since 2006, and have used every version since 10.5. Lack of 32-bit support is now a normal part of owning a Mac, but it can still be a bad surprise whe you stumble upon a 32-bit game your Mac cannot run.Okay: I've used computers since 1983. But most never publicly communicated any plans.ģ2-bit games for Mac: Stay away from these ‼️ Some developers, such as Aspyr and Feral Interactive, were open about which of their back-catalog games wouldn’t be updated to 64-bit. PS: New games (from 2019 onwards) are always 64-bit, therefore you won’t see us update this list with every new game released in 2021. To help you navigate these uncertain times, this page tracks all the Mac games we know that are still 32-bit (or that were 32-bit but were recently updated to 64-bit).

With that, upgrading to the latest macOS version meant giving up on hundreds of apps and games, including some you already owned. It was with MacOS Catalina, released in October 2019, that Apple actually pulled the trigger and completely removed support for 32-bit applications.
