How do I download a Minecraft mod on my macbook air?

You would be best asking this question on a minecraft community(such as planetminecraft.com, and there are plenty of videos for that, but the main thing is getting to the library directory. to do this, click finder, then on the top of the screen you will find GO. Click on GO and hold down "option". When you do that, "library" will pop up, so click on that. then once you are in library, go to application support ----> minecraft -------> bin ------> then you will find your minecraft.jar. click on it once and hit enter, so you can rename it. rename the file to minecraft.zip (say yes when it asks you if you want to change the extension). then double click minecraft.zip and you will get a folder called minecraft. rename that (hit enter on the document) to minecraft.jar. then enter the file and drag and drop the files of the mod. Search for META-INF in the file, and DELETE IT. then start minecraft, and you should be done!

Hello,

I was trying to help my son figure out how to download Mods for Minecraft and we followed your instructions. Not sure where I went wrong, but Minecraft wont work after.

We keep getting a message “Minecraft Downloaded” and the status bar shows fully downloaded…. But is frozen.

Is there any way we can undo what we have done?

Do you think you can help us resolve this issue?

We need help!!!!!

Thanks....
