My Minecraft game always freezes after I play for about 10 minutes.

Please force a crash by pressing F3 + C for 10 seconds while ingame and attach the crash report here.

Please do not mark issues as private, unless your bug report is a security issue containing information that may compromise your server/client.

I have a Macbook so I am not able to press F3, what can I do instead on a Mac?

You should have an FN button on your mac that should permit you to press F3, but if that doesn't work, you can change your function keys to work as function keys by going to 'System Preferences'/'Keyboard' and changing the function key setting.

anyway to fix it thats my crash report above

This ticket is invalid as it relates to a modded or 3rd party client/server.

• Any non-standard client/server build needs to be taken up with the appropriate team, not Mojang.

• Any plugin issues need to be addressed to the plugin creator.

• This site is for addressing issues related to the base unmodded MineCraft.

(You have MCPatcher.) Also, the game probably crashed due to the large amount of paintings around and you should update your Java.

nono it happens in single player and on multiplayer and tails it got mcpatcher to try and stop this i got this i kept freezeing without these mods :L

As Anon Ymus already stated try updating your Java.
