I have seen on Magic Lantern's website that it is possible to put ML on a 6D, but it requires a few more steps than usual. Has anyone successfully installed ML on their 6D? I really need some help on this. Thanks.

Here's a link to a guide I found while looking for the same answer, I think it's okay to post but moderator please tell me if not:
6D - Install guide and raw shooting. (http://www.magiclantern.fm/forum/index.php?topic=5530.0)

It appears that the 6D is working with ML though I haven't tried these directions yet.

I followed the steps in that forum and it works just fine. Quite laborious but it's been fun. Here's a few shots I did at different resolutions:

I have tried a nightly build, it works; but still isn't as developed as other camera versions yet... My biggest need was headphone monitoring, it appears they have it now listed in features list. I am using it to aid filming, not shooting raw video (yet)
