OS X user other than installing user can't open app

[NilsEnevoldsen]

Replication:

1. Install app as user Alice
2. Try to run app as user Bob
3. Receive error about PowerPC applications not being supported

The issue appears to be permissions on the executable files:

• /Applications/Livestreamer Twitch GUI.app/Contents/MacOS/nwjs
• /Applications/Livestreamer Twitch GUI.app/Contents/Frameworks/nwjs Framework.framework/nwjs Framework
• /Applications/Livestreamer Twitch GUI.app/Contents/Frameworks/nwjs Helper.app/Contents/MacOS/nwjs Helper
• /Applications/Livestreamer Twitch GUI.app/Contents/Frameworks/nwjs Helper EH.app/Contents/MacOS/nwjs Helper EH
• /Applications/Livestreamer Twitch GUI.app/Contents/Frameworks/nwjs Helper NP.app/Contents/MacOS/nwjs Helper NP

Running sudo chmod [file] a+rx on these files fixes the issue.

700 are the default file permissions of all executables in the .app folder.

These are set by the NW.js archive which is being downloaded by nw-builder. The builder doesn't change any file permissions. That was the reason why the first OSX builds of the current release were corrupted (#200)...

I don't want to manipulate the OSX build procedure here...
Please report this issue over there at the nw-builder repo or maybe even the NW.js repo.

Thanks!

I decided to include a fix for this issue here, since the nw-builder maintainers seem to be inactive again and are not interested in a fix.

The new NW.js builds on Linux also have invalid file permissions set (only user permissions). The solution for this mess is simply running chmod -R g=u,o=u,g-w,o-w /path/to/app, which copies user permissions to group and other and removes write flags on those.
