Proc not available on macOS – consider psutil

[jrmedd]

I arrived at this repo via Stack Overflow. While I'm aware it's a good few years old, I figure I'm not the only one who'll land here.

Currently, process-watcher gets its list of pids from /proc. Given that /proc is unavailable on macOS, I'd suggest psutil as as good cross-platform alternative.

Example of its usefulness: psutil.pid_exists(12345)

I've been looking to extend process-watcher with support for Pushover so I may do this myself and submit a pull request, if I find time.

Thanks for sharing.

@jrmedd Thanks, I haven't worked on this project in a long time, if you're interested in maintaining it I could transfer it to you.
