Can’t but repost it! (original is here: http://www.mactricksandtips.com/2009/07/hide-the-menubar-or-dock-in-specific-apps.html)
It turned to be an old feature, that actually required a .plist file editing, but it’s been existing for a long time! It’s not an innovation of MacOS X Lion! You can set any of your application to be fullscreen, always. Just put it in presentation mode by going to Applications -> ANYAPP -> right-click -> Show package contents -> Resources -> Info.plist and add the following lines after <dict> tag:
Substitute “4” with any of the following:
- 0 = Default, nothing will happen.
- 1 = Hides only dock, shows it back when hover the cursor in the lower part of the screen. Requires reboot.
- 2 = Hides only dock with no hover over function. Requires reboot.
- 3 = Will hide the menu bar and dock and wont show them when the mouse hovers over.
- 4 = Hides the menu bar and dock, and will appear when you hover over them.
I made it for Logic Pro:
