What's Wrong?

each instance of claude code is using anywhere from 2.5-3GB to 8GB of RAM, on a MacBook Pro M4 Pro with built-in GPU. nothing has changed on my macbook other than claude code auto-update, whenever that happened. See this:

What Should Happen?

if 1 claude code terminal takes up on an average 4-5 GB of Memory, MacBooks are not just running out of battery but there's not much we can do with claude code in 1 terminal !
