OMG IT FINALY WORKS!!!!!!!!!!!! ok at first it did not work BUT what i did is that it showed me what to put in "and by default it has /system/ on the minecraft launcher "all you need to do is remove that and it should work!!!!
OMG. You guys have no idea. I have been trying to Get CLay soldiers to work on my mac for the past week. And If It hadn't been for this post I would've never found out how to get it. But after studying this post for a few hours, I just ran it and it Works. It finally works. This feeling is sooooo great! Thanks so much!
The method is the same, just choose a path for Java 8 rather than 7. I cannot provide you with a default path that will work on your computer, you will have to go through either of the tutorials on the OP.
Of all the bizarre and marvelous coincidences, I found a solution in a thread dedicated to a mod that had nothing to do with my trouble. On page 103 of the "Enchanting Plus" thread on these forums, user JustAStupidName [yes, that's the username he chose; I'd give him a much more flattering one] outlines these steps for Mac users wishing to use Java7:
-Go to System Preferences … -> Java -> tab: Java -> View -> Path
-Copy the path value found in the above step.
-Start Minecraft; chose the profile Forge (or create a new profile) and click Edit Profile
-Under Java Settings (Advanced), check the box next to Executable and paste the copied value
-Click Save Profile
And that did the trick for me. I'm posting this solution here, as an appendix to the kind work Ivorius has done.
