Mac Performance Guide is quite negative on Mac performance, and it is the only place I have seen to show negative performance of Mac Studios, and he is certainly right on the Core Rote in Apple Systems. And this article on Spotlight Indexing is very interesting as I hate when does things that you have no control over. Spotlight is one of those things, especially when it indexes and you have no control over it. A simple pause indexing would be an amazing thing.
Personally I hate Spotlight as it doesn’t find everything for me, I use Find Any File for any major searches.
And for core rot I have to bring up my issue with Apple Music and moving iPhone sync to the finder. Also the fact that the damn sync has to sync twice to sync any files to my phone. Why? WTF!
