Reinstall Java and mc if that fails make a new account on your computer, and you're definitely not hacked though I have a hatred for apple products I'll admit those things are about as secure as fort Knox, regardless I do see that your client is modded care to tell which one it is? Optifine has had a few issues with macs in the past

[Jao]

I tried using an alt and that didnt work I tried reinstalling Minecraft so I'll try Java maybe

EDIT: Java didnt work ;(

[Jao]

I do not have any clients installed not even Optifine i dont think. What do you mean hacked clients or Like mods

[CollisionCourse]

In the java report at the very bottom it says "Is modded" meaning a mod of any type is installed

[Jao]

I'm not using any apart from a few modded clients (only using becaause a server says you can to help build).

In the java report at the very bottom it says "Is modded" meaning a mod of any type is installed

"Is Modded: Probably not." If he's reinstalled Minecraft, that should have cleared all his mods anyway.
It says your Java version is 1.6.0_65. The recommended version is 7 Update 67, download it here: https://java.com/en/download/manual.jsp

I apologize, I was incorrect, must've skimmed over that

[Jao]

I have succesully downloaded java 7 but when I open up MC and then when it Crashes this is what the java version looks like

Java Version: 1.6.0_65, Apple Inc.
   Java VM Version: Java HotSpot(TM) 64-Bit Server VM (mixed mode), Apple Inc.
But I d have java 7 installed anyone have any ideas?

[CollisionCourse]

Try to get an older java log from when it worked for comparison

[Jao]

But you can't get crash reports from when it worked?

[CollisionCourse]

Did you use an alt account for mc or an alt account on your computer

[Jao]

alt for MC. I have asked my family and we believe we have a virus we will try and clean it and then I will ask if needed.
Please could a Mod temperarily lock this then if I want it back open can they unlock it please

[DeeKay]

No need to do that

[Jao]

Why?
