As any Mac user knows, running Command and Conquer Generals (including Zero Hour) tends to crash on startup on a Mac running OS X. Here’s how to fix it.
Launch “Activity Monitor”, and from the “View” menu, choose “All Processes.”
Then, search for “gamed”. If it shows up here, it’s running and C&C Generals will crash immediately.
To get rid of the “gamed” process, you need to open Terminal and type the following command:
launchctl load -w /System/Library/LaunchAgents/com.apple.gamed.plist
Now, when you launch Generals, you will be prompted with several dialog boxes. It’s important that you do NOT select Game Center. You can play multiplayer on the same network WITHOUT Game Center!
On the first dialog, choose “Cancel”.
On the second dialog, choose “Single Player Only”.

Sadly, I had this experience lately. Even though I had the firewall explicitly set to allow connections using Screen Sharing, for some reason my Mavericks OS X 10.9 server hiccuped and I couldn’t access it via screen sharing.
Here’s how I resolved my dilemma:
Here’s a cool tip from The Distant Librarian on how to silence the audio feedback you get when using the keyboard to increase or decrease the volume in Mac OS X.
Hold down the shift key while depressing the volume keys will silence the auditory feedback while raising and lowering the volume, but still show the visual cue.
Other cool tricks:
Hold down option while clicking one of the sound keys to access the Sound system preferences.
Get more granular volume control by holding down shift-option while clicking one of the sound keys to increase/decrease volume in 1/4 the normal increments. Normal, the Mac provides 16 volume levels. Holding down shift-option gives you 64 increments.
