In short, the mod seems not to be working. Do you have any suggestions?

Thank you, guys! I was able to make a Creative Mode version of the save file, soon deleting the Ender Portal (I succeeded!)!

Many, many thanks,
A satisfied Minecraft playerThanks especially to GamRz for suggesting NBTedit.

Dear Minecraft Forum users,

Recently, using the script option in the inventory editor, InvGrid, I acquired an infinite end portal block, setting the quantity number to 255. I placed this block on top of a plain stone brick block, and when I tried to destroy it, I did not succeed. I tried TNT, water (in which case the water just went over/around it), the fist, and the pickaxe, and I did not succeed. Any suggestion of how to destroy the block would be helpful.

Many thanks in advance!

Sincerely,
Minecraft Player in Need of Help

P.S. My computer does not support mods, as far as I can tell (I use a MacBook Pro).

How to import survival mode map into creative mode game?
I tried to import the level.dat file from the survival mode game into the creative mode game, but it also changed the mode. I tried the mod, deleting the Meta-inf file, but it would either turn black or freeze at the "Updating Minecraft" page. I have a MacBook Pro. Help?

I did everything you said and deleted meta-inf. Nothing. Black screen. What to do?

Spawner GUI Beta 1.7.3: I put the mod .class files into the minecraft.jar FOLDER (folder is named minecraft.jar; original file is 1minecraft.jar), the gui .class files in the gui folder in the minecraft.jar FOLDER. Then I take the .class files from the ModLoader Beta 1.7.3 folder and put them into the minecraft.jar folder (which is in the bin folder). I replace all files with the same names. I have Minecraft Beta 1.7.3. I then open up Minecraft (not in browser), and the screen goes black after I log in! What have I done wrong?!

I have a MacBook Pro, and after I had a bit of problems with texture packs becoming default, I deleted all Minecraft files and reinstalled the game. Unfortunately, when I tried to open it, there would be a moment when it looked like it was about to open, the app bar sliding a bit. The very moment after, it closed in semi-opening. I hear it could be a Java problem, but I'm not sure. Does anybody know why this could be?

For some reason, after I installed the mod, I opened Minecraft and tried the recipe, and it didn't work.

Do you know why this may be?
