No, you are not the only one. Texture Packs for me work though.
Either you are installing them incorrectly, or they are incompatible with the version of minecraft or each other
Yes, the exact same way as with regular.
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 Or your computer is probably outdated.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it and put it in your mods folder if this does not work then read the installation instructions because this could be out of date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.
There are hundreds of mods made by hundreds of people. They go from a single simple mod to dozens of mods that will put your computer to hard work to run them. Just do a search on the internet for minecraft mods and pick from the ones you like. Be aware tho that not all mods will work with other mods made form other people. You HAVE to read the directions of the mod to keep from crashing the game. Also be aware that every time Mojang updates the game the modders have to redo each mod to be compatible. It could be hours to weeks for some mods to work again.
