No, you are not the only one. Texture Packs for me work though.
no mods dont work
Have you tried to download mods? If so, some mods aren't really mods, they're scams and they hack your computer so minecraft and other programs on your computer won't work. If you usually don't shut off your computer every day, then shut it off and try playing Minecraft in-browser again.
Minecraft 1.4.6 mods will work with 1.4.7 sense they are both a 1.4.
All mods that dont add items/blocks to the game, or spawn items (cheat in anyway) will work
Have you checked the version? (bottom left of minecraft application) It might not work because something may be required on the other computer. Or your computer is probably outdated.
The Server has to install the mods Not You.
No
No your have to wait for the mods to update which may take some time.
you go download it then run it and put it in your mods folder if this does not work then read the installation instructions because this could be out of date
This is a question to ask on the My Minecraft Mods forum topic. It may not be compatible with a Mac yet.
They don't.
The Vanilla version of Minecraft refers to the game with no mods or texture packs installed.
