So one day, I want to get onto Minecraft, and once I choose 1.7.2 and hit play, it crashes. I try Mc Forge, crashes. Downloaded a Hacked Client, it crashes. But it used to come up as Minecraft. It now comes up as net.minecraft.client.main.Main. Here's the thing, I updated my computer, and when it happened, I checked the forums and it says that I had to upgrade my graphics card, and I want to avoid it. COMPLETLY. Is this a glitch? Is it that the new update dosen't work with my OS X? Plz can you respond quickly? I was psyched to start my channel! Thx!
