As an OSX user I had problems with VS Code only on 2 occasions: 1. Syntax highlighting gives up on larger files. What can be considered "large" depends on your machine of course. In this situation I use Sublime Text. 2. I worked on a web frontend that used React MUI (Material UI). That particular version of MUI & VScode combo didn't work at all. Intellisense would slow the editor down to where it was barely usable. That was a couple of years ago, never seen this issue again.
