The short answer is no, MacBooks are not good for gaming. While MacBooks are recognized for numerous advantages, they're not commonly the first choice for avid gamers.
The 14-inch MacBook Pro with M3 Pro chip is a good option for gamers. We suggest that if your budget runs to it you should opt for the mid-range model that comes with 1TB SSD, 12-core CPU, and 18-core GPU (forR$2,399/2,499). That way you avoid the slower SSD of the entry-level model, and get the extra GPU cores.

If you have not had Steam Guard enabled for 15 days, you will be unable to trade or use the Community Market. Accounts that currently have Steam Guard disabled will be unable to trade and use the Community Market.
