Even the same with me. I am using MacBook Pro M1 Pro 16" 2021 with 512 GB of storage and 16 GB of Memory. 9 GB of Memory used just with 2 Safari tabs and Activity Monitor. More than 4 GB of Memory with a specific lightweight application, which most people use for messaging worldwide. While using Xcode with the simulator running and Safari with two tabs, it uses more than 3 GB of SWAP. They are telling me to take the backup of my MacBook and reinstall the OS but all of my external drives are full. I just switched from Windows to Mac, such a horrible experience and it just got in this month.
