Hi,
I noticed this myself yesterday once or twice and was stumped as to what was causing it, I’m running Sierra 10.12. A student of mine experienced it too today in class, he’s running Mojave 10.14.6.
Both of us saw the same problems described by @boonier_due in his first post.
I thought it might be the white-spaces thing after reading this, and I could recreate the bug by adding white-spaces too, but then I realised none of the names of the csds I was running previously had any white-spaces (I try and avoid them like plague when naming files) and neither did my student’s.
This was the case for me too but it doesn’t seems to trigger the process that’s hogging the CPU though. Something else must be causing that, I can’t recreate it though.
I ran activity monitor when this had happened previously (and today in class on the student’s laptop) and I saw a process using +90% of the CPU called CsoundTest which I had to force quit.
This process continues to run even after quitting Cabbage.
Weird.
