Hi,
From 1.6.6 on OS X El Capitan the function open with doesn't work anymore (arduino apps open but without the file to load only the default sketch).
I have 1.6.5 installed to and it's working with this version.

I saw the same thing, I opened an open issue for it if you want to add any details:
Update: It's already been fixed in the 1.6.7 Hourly builds.
