Fails to flash board - Githubissues

For the PrintrBot firmware uploader, on OSX, I can not get it to flash new firmware, the app gives me this “error”

Error!

Unable to flash new firmware. Please check your Printrbot Plus connections and then restart this app to try again.

/bin/sh -c export DYLD_LIBRARY_PATH=/Users/USERNAME/Applications/pbFU.app/Contents/Resources/app/resources/dfu-programmer/lib; /Users/USERNAME/Applications/pbFU.app/Contents/Resources/app/resources/dfu-programmer/bin/dfu-programmer at90usb1286 erase

When I try to run the commands directly in terminal:

I’m not 100% certain, but it appears that the dfu-programmer may be hard-linked to the developer’s computer? I didn’t want to dive too deep in to the app to figure out if something else was going on, but thought I’d mention this as a potential bug.
