unable to find any devices connected to your computer - Mac

Hi. This topic has been raised in some previous incarnations but all seem to date back to 2013 at the latest and don't correspond to the most current operating system, so if anyone has any tips on how to resolve this, I would appreciate it. 

I have a KNK Maxx Air, model ACS-24HF that I purchased used. The machine itself seems to be in fine working condition as much as I can tell so far. I am using an iMac running OSX Sierra 10.12.1. I am connected to the cutter via a usb cable. I downloaded the MTC disk image and followed the instructions in order. However, when I open MTC Bridge I am given this error message: "Error... Unable to find any devices connected to your computer. In order to bridge devices to Make The Cut, you must have the devices connected to you computer and they should be powered on".

Once I choose to "continue anyway", the usb connection is not listed in the drop down menu, leaving me at a dead end for now. I tinkered with downloading Wine to see if I could run the .exe version but Wine repeatedly crashed while trying to save the .app version. I don't really want to go that route anyway because I'm sure it's buggy. Surely, I can't be the only one out there running MTC on the latest software. Does anyone have any other pieces of advice for getting the computer to recognize the cutter?

     I have a zing and Sierra, and the directions are basically the same with the Max on Mac. MTC is fine and will work but - You  have to make sure the gate keeper is set to all users. With Sierra you have to go into the terminal app to allow this since Apple in their arrogance has made changes to prevent nonapple developers a piece of the pie, See to see how: http://osxdaily.com/2016/09/27/allow-apps-from-anywhere-macos-gatekeeper/.
    Also did you download the most current version of MTC for Mac and follow the instructions in the video? You have to make sure you also drag over the drivers. I would start again after restarting your computer.

    Hi Leslie. Thank you. This worked for me this time. I may have done something wrong modifying the gate keeper security settings before. I also restarted before reinstalling everything. MTC is now running, but does still seem ~unstable. It has "encountered a serious problem" twice and had to be shut down before I ever got to the cutting. Do you ever have this same problem?

    Do you recall what you were doing at the time it shut down?  Were you working with something very basic or doing something like importing an image to trace?

    I do not cut with my mac, only design so I do not have an issue with MTC. . It only crashes when my files are too large. Did you try the built in mac disc first aid to fix your disc?
