MY journey so far....
- first 16" MBP M1 Pro had faulty SD Card Reader > returned
- second 16" MBP M1 Pro resolved the SD Card Reader, however the speakers were noticeable less powerful and missed the bass of the first machine > returned
- third 16" I decided to try an open box M1 Max from Best Buy > both SD card works and Speakers sound phenomenal again. Battery life is worse however I can sleep at night knowing I will be able to game when more games get optimized over the coming years.
