When Mathematica launches, it always creates a ~/Documents/Wolfram Mathematica directory.
I've already tried editing ~/Library/Mathematica/FrontEnd/init.m with:
NotebookBrowseDirectory->"/Users/myusername/Documents/Wolfram",
But the "Wolfram Mathematica" dir still gets created.
It's an issue that's quite a few years old with no apparent solution and it doesn't appear the Mathematica folks have an interest in addressing this ongoing annoyance unfortunately. I first attempted to fix this a few years ago and didn't make any progress.
Wondering if anyone out there has found any hack to deal with this.
Thanks!
