java.lang.OutOfMemoryError: PermGen space

Increase your permgen.

How do I do that on mac

Im new to mac I used to have a windows

I believe you need to allow Java more RAM. To do this (I'm assuming you are using the 1.6+ launcher), in the launcher:

1. Choose "Edit Profile" in the bottom left-hand corner
2. Turn on "JVM Arguments"
3. Now enter "-Xmx2G -Xms2G" inside the JVM Arguments without the quotes
4. Click "Save Profile" and launch Minecraft

Thank you I will try that

It didn't work

Here is what the code is in the launcher:

-Xmx2G -Xms2G -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode -XX:-UseAdaptiveSizePolicy -Xmn128M

Hmm, I'd recommend to give Minecraft 1GB less of ram then what your Mac has,

to check how much RAM your Mac has, go to

1. The apple menu in the top left-hand corner
2. click on "About this Mac"
3. Click "More Info"
4. Then select "Memory"

It should say in there

So say your Mac has 4GB of ram, you would add

-Xmx3G -Xms3G to the JVM arguments

If you have 6GB of ram you would add

-Xmx5G -Xms5G

and so on.

It's not a memory issue you are having it's the permgen size issue.

-XX:PermSize=256m -XX:MaxPermSize=512m

I also suggest upgrading to java 7 at least since it looks like you are using 1.6.0.

Problem is getting a mac to use java 7 or 8. You can use a text file or change the java directory in the launcher.

Ok thanks all it is now solved
