The previous method of enabling Front Row in Lion & Mountain Lion, namely, copying system files from a working Snow Leopard installation (see
http://www.mac-hatter.com/blog/frontrowenablerforlion)
also works in Mavericks.
Mostly. The following caveats apply:
1. Using the screensaver function in FR will cause it to quit after ~30 s, regardless of whether you are staring at the main menu, playing a video or starting a slide show. To prevent this quitting, disable the screensaver in FR: FR->Settings->Screen Saver->Off.
If FR is quitting before you have time to change this setting, you can temporarily disable your screensaver in System Preferences->Desktop & Screensaver; this will give you as much time as you need to change the setting in FR.
2. Just like on Lion & ML, iTunes playback (music, TV shows etc.) doesn't work in FR on Mavericks, unless you downgrade iTunes to v. 10.3 or below - see
http://www.emacconsulting.com/apple/itunes/downgrade-itunes-11-to-itunes-10-7/ for details. (I have no idea if this will work on Mavericks.)
3. Starting FR can be a bit of a pain, as the native 'esc' shortcut and long press of the menu button on the IR remote no longer work. I fixed this with BetterTouchTool (
