Description
[EDITED by PropGit - Issue title renamed; it was first thought to be a problem with opening a file (and hanging) but later seemed to be a problem due to specifying a tty port instead of a cu port on the Mac]
I'm on a Mac, trying to load some code on to my Quickstart Board, and I'm having a very strange error. When I'm in the spin-standard-library repository that I cloned to test out the demos, I can compile (using OpenSpin) all the files fine and upload them over serial to my Prop. However, if I copy the files anywhere else on my computer, PropLoader will just say "Opening file 'temp.binary'" and hang forever.
The weird thing is that when I copy any other spin or binary files into the Spin Standard Library directory, they can upload fine. When the process hangs, it doesn't use any CPU, it just resets the prop and prints that message. I sampled the execution after it did this:
Sampling process 43491 for 3 seconds with 1 millisecond of run time between samples
Sampling completed, processing symbols...

Any ideas? The proploader binary is in /Users/dev/Documents/Programming/git/PropLoader/proploader and is symlinked to /usr/local/bin/. The only directory that seems to work when uploading is /Users/dev/Documents/Programming/git/spin-standard-library and its subfolders.
