I’m not gonna stand up and declare that 8gb is absolutely fine, because in very short order it won’t be. But yeah, currently for an average use case, it is.
My work Mac mini has 8gb. It’s a 2014 so can’t be upgraded, but for the tasks I ask of it it’s ok. Sure, it gets sluggish if I’m using the Win11 VM I sometimes need, but generally I don’t really have any issues doing regular office tasks.
That said, I sometimes gets a bee in my bonnet about it, so open Activity Monitor to see what’s it’s doing, and am shocked by how much RAM some websites consume in open tabs in Safari.
8gb is generally ok on low end gear, but devs are working very hard to ensure that it’s not.
