I’m having a terrible time with Rack on my Mac Pro. It’s a 12-core Xeon system with 32 GB of RAM running Mac OS High Sierra 10.13.6. The Rack version is 1.1.4. It starts up just fine, but crashes immediately after the first few mouse clicks, no matter what they are (Library update, File Open, etc.). The Activity Monitor indicates that Rack is consuming almost all of CPU. The odd thing is that Voltage Modular works just fine on this system.
I also have Rack 1.1.4 on another Mac Pro running High Sierra 10.13.6 on a 6-core CPU, which is not crashing, as well as on a MacBook Pro running Mojave.
Any thoughts on why Rack is not happy on my most powerful hardware? Where would I start looking for the root cause(s)? Thanks!
