Let me do some further research, I know I have the mac App store version on the laptop as well, and that one is where I had it not work, even after disabling SIP and deleting and re-downloading. Don't know what is going on with this yet. The Mac Pro is pretty old, it's a 4,1 from 2009 modded to a 5,1 and had dual Xeon 2.93 GHz quad core chips added in, started life with my stable on MacOS 10.9? and it's been upgraded and updated since then, might have something to do with it. I'll probably be able to find out more this week, but it's not JUST the mac app store thing that is at work here if at all.
What version of Mac are you using?
