The author of the text has upgraded to a Mac with an M1 Max system-on-chip, which provides improved performance and capabilities compared to their previous M1 MacBook Pro. The main benefits include faster builds, smoother user experience, and better support for multiple external monitors. However, some issues like Docker for Mac performance, VPNKit stopping working, and lack of native Discord app support are still being encountered. Despite these challenges, the author finds that the M1 Max is a joy to use daily, with features like mobile usage, satisfying keyboard typing, instant website rendering, and smooth terminal scrolling. The investment in an M1 Max machine seems worthwhile for engineering teams, especially considering the significant productivity gains from faster builds and tighter feedback loops.
