I have macbook air with M1 chip, I wish I could change to linux but unfortunately I cant so I try to stick as much as possible to using open source on macos. But i cant understand why FOSS apps take up so much space in memory. I'm even getting messages that says that I dont have space left in memory and i must close apps, and I thought that chip M1 was enough with 8gb of ram. I send a pic of my memory usage.
My guess is not optimized or not optimized for your OS. Plus there may be an extra layer to make it compatible that may be resource hungry. That being said, I’ve seen my fair share of resource hungry paid and closed apps too.
