Can't Open Wireshark After OS X 10.10 Yosemite Upgrade

Reading online produced the conclusion that X11 Quartz (a dependency of Wireshark) had been moved from /usr/X11 to /opt/X11 as a part of the upgrade to OS X 10.10 (Yosemite). To restore the ability to open Wireshark, create symlink from the old location, /usr/X11 to the new location, /opt/X11.
sudo ln -s /opt/X11 /usr/X11
Now try launching Wireshark. The first time I launched it took ~60 seconds to load. All subsequent launches took considerably less time.

OS X 10.10 Yosemite MySQL Wont Start At Startup

After upgrading to Yosemite, I noticed MySQL would no longer start on startup even though "Automatically Start MysQL Server on Startup" was enabled in the MySQL system preferences.

I'm not certain what caused this to break, but I suspect the LaunchDaemon file that MySQL 5.6 uses is no longer being recognized. Maybe the location it is placing the .plist file has been changed in OS X 10.10.

To resolve I created /Library/LaunchDaemons/com.mysql.mysql.plist with the following contents:




  
    KeepAlive
    
    Label
    com.mysql.mysqld
    ProgramArguments
    
    /usr/local/mysql/bin/mysqld_safe
    --user=mysql
    
  



Then load the newly created plist file
sudo launchctl load -w /Library/LaunchDaemons/com.mysql.mysql.plist
