I've had a couple of reports that I've not been able to replicate of OS X users having plugins not loading properly. A few people have had trouble with the Alignment plugin, and had to open the Alignment.py file and re-save it to get it to work.
I've also experienced this with the SFTP plugin, however I do not distribute the raw source in order to preserve the ability to license it, so only the .pyc files are included. I'm working on the exact same version of OS X and Sublime and for some reason I currently have two users who see all menu entries, just disabled. I've seen this before if the python contains an error that prevents loading the relevant command classes.
There are no errors in the console, the __init__.py script it being listed as loaded, yet the python command classes appear not to be loading. Completely removing and reinstalling the package has no effect. I even refactored the whole plugin from a single .py file into a directory of around 20 .py files. The .pyc files are all present on both machines, and of the same size.
Anyone have ideas about what could be going on, or ideas to try? I've tried installing all of the other packages the users had to see if it was some sort of conflict, but I was unable to find anything.
