Can my Mac run UE4?

Mac OS catalina
MacBook Pro (15-inch, 2016)
Processor: 2.6 GHz Quad-Core Intel Core i7
Memory: 16 GB 2133 MHz LPDDR3
Graphics: Radeon Pro 450 2 GB and Intel HD Graphics 530 1536 MB

I’ve run UE4 on a similar machine - even lower spec machines. It should work fine, but your laptop may get hot and throttle. Just be patient as UE4 is high demand software. The only way to know for sure is to install and run. Have fun!
