macOS Catalina for Development Use?


I'm currently still on macOS Mojave, wanting to upgrade for better memory allocation. Is Catalina stable enough to use day to day for development?

EDIT: On memory allocation: somehow in an update Mojave just wrecks the RAM usage and aggressively swaps stuff. I'm down to two/three windows of Chrome (with ~10 tabs each) and a VSCode window. Memory usage is under 4GB Wired + Active, but the OS still prefers to swap (I have 8GB of RAM). Especially after > 1 day of uptime. I'm not sure what's happening.

This screenshot[0] is at what I now consider "worst" scenario, 5 Chrome windows, multiple slack instances in tabs, Miro boards with a lot of objects, 2 VScode windows, 2 node servers. It's clear that the ram is still enough the the OS still swaps. Really bums me.

I would stay on 10.14 for now, it is far more stable than 10.15, especially the latest update which seems to cause kernel panics for many people.
