In the last episode of ATP (at time of printing, as they say) our faithful heroes discuss Catalina being slower than earlier releases.
Allan Odegaard of Textmate fame has written a little analysis of the situation here with numbers and some very detailed and interesting explanations.
I don’t really know how to feel about this. I do know I agree - macos is slower now, and yes it is design choices that have made it this way. But is it worth it? It’s possible I’m not the best person to decide, as I’m lucky enough that my work pays for a really kick-ass Macbook Pro for me.
However, I tried to format that machine just a couple of weeks ago to get rid of what I assumed to be cruft in the system, and it had no effect other than wasting a weekend and forcing me to make some choices about which software to reinstall. The OS is clearly slower than it was!
