PLEASE MAKE IT COMPATIBLE!!!

I just bought portal 1 and 2 through a bundle on steam on my macbook air and as it turns out, its not compatible because modern macOS doesn't run 32-bit games, I don't wanna spend more money to make this work but otherwise I don't know how to play the two games I just paid for, whoever is responsible for stuff like this please make the portal games work on modern macOS PLEASE i'd really appreciate it
