[Mac] SC2 1.5.1 Error Troubleshooting (Updated 8/13)

Mac Technical Support
1. The launcher attempts to patch to 1.5, but automatically quits.

    This error indicates that the game is attempting on Mac OS X 10.5. As of StarCraft II patch 1.5, Leopard users (10.5) are unable to launch, patch or play StarCraft II.

    Upgrading to Mac OS X 10.6 and above will resolve this issue. Currently the only way to purchase 10.6 disk is to contact Apple (1-800-MY-APPLE) and purchase the 10.6 DVD from them for $29.99.
2. The file "/Applications/Starcraft ll/Updates/XXXX.MPQ" appears to be corrupt.

3. An unexpected decryption error occurred. Please contact Customer Support.

    This error indicates that the Installer Tome 1.mpq file is not completely downloaded.

    Check the /Applications/StarCraft II/Temp folder and see if you see a Installer Tome 1.mpq.part file. The .part file indicates the file is not complete.

    Use the following steps to attempt to resolve this issue:
      1. Force quit any Blizzard Downloader, Blizzard Updater SC2, Agent and Blizzard Launcher processes in Activity Monitor.
      2. Navigate to the /Applications/StarCraft II directory.
      3. Delete the Temp folder.
      4. Relaunch the launcher and attempt to patch.
4. An internal error occurred, please restart. If the problems persists, contact customer support.

5. You need an authorized language pack from Blizzard Entertainment to use this language.

    This indicates that some of the variables.txt files settings were changed in the client during patching. See this support article to help resolve this issue.
6. Crashing at startup (On Jim Raynor's face loading screen)

    If experiencing issues crashing upon startup at the Jim Raynor face loading screen, this may be due to a compatibility issue with the program called Hear

    Check your sound plug-in files and remove this plug-in to resolve these crash issues:

      1. Navigate to /Library/Audio/Plug-Ins/HAL/Hear.plugin
      2. Drag the hear.plugin to the trash

    We've escalated this to ProSoft for assistance in resolving this issue.
7. Low performance after updating to 1.5.x

    We have seen several reports regarding stuttering and other performance issues, for both Mac and PC users.

    Mac users, please follow the performance troubleshooting steps listed in our SC2 Performance Troubleshooting support article.

    If the issue persists, please go to THIS THREAD and post the information requested. We are currently collecting system information and variable information from users who have encountered performance degradation after 1.5.
8. It is possible to enter games late when starting matches

    When starting a match, sometimes users are entering in a few seconds late. This is something we are looking into.

    Some users have had success in lowering graphics settings to start matches on time. Please try lowering graphic settings to see if this helps. You can see steps for lowering graphical settings in our Overheating Prevention article and post in the Bug Report forums, so that the team there can investigate these reports: http://us.battle.net/sc2/en/forum/13440/
9. Using command+left click to select a group of the same unit is not working when "Use command instead of control for hotkeys" is enabled.

    This is a known issue, which we're working to resolve. Some users have suggested various workarounds that may help with gameplay in the 1.5.1 Command-click issue thread: http://us.battle.net/sc2/en/forum/topic/6293819652

    We apologize for any inconvenience this may have caused.
