It would be nice for OCRA to support building one click applications on OSX as well. I, the author (larsch) do not have any experience with OSX development (nor do I have to an OSX installation), so if anyone is up to the task, feel free to contact me.
The primary task is to write the stub executable for OSX, or rewrite the existing one in a portable manner (it's currently highly Windows-specific). The main Ocra script may also need minor tweaks to handle platform differences.
Given that recent versions of OSX (>Tiger) have ruby installed by default is there really a demand for this? I tend to package up my ruby apps using Platypus.
I am going to start looking this. I have both a linux and osx machine.
As far as I'm aware, OS X still lives at Ruby 1.8.7 and thus you're still stuffed if you rely on 1.9.2.
Even in the case of 1.8.7-compatible applications, it would save the user having to manually gem installing bundler and run bundle install (yeah, not much effort, but you know users).
I currently use a .app package provided by the author of Gosu in order to distribute my games on OS X (it might be a place to peer at). https://github.com/jlnr/gosu/wiki/Ruby-Packaging-on-OS-X
OS X version 10.9 and 10.10 are on much newer versions of Ruby. This is with the Yosemite beta (i.e. 10.10):
