Please slow down and why all the hostility? I never said that you live on this forum. That was merely my way of asking for patience in waiting for a reply instead of demanding a response. Thank you.
The
basic troubleshooting guide is meant to rule out anything that might have become corrupted and/or user installation setup. It is meant to establish a baseline to ensure that nothing covered in the guide is the cause. You'd be surprised how many things that guide fixes even things that seem rare.
Since you are new to minecraft, as you pointed out, then you probably do not know this. Yes if you left click on the crafting table with the items in your hand your character will place all the blocks in your hand in the crafting table. Instead with the blocks in hand right click and this will place one item at a time. If this is not your problem for crafting and since it is all the packs you might want to check if it is a mouse problem. Try another mouse and check your Mac mouse settings.
For the biomes mods not showing up. Depending on which mod pack you are on, some of them have the mod either disabled by default or you must select which biomes mod you wish to use when you create a world. To do this ensure the mod is in the Enabled portion of the screen when you click on Edit Mod pack. Then when creating a world click on 'More World Options...' button. Now click on the button that says 'World Type: Default' until you see the biome mod you wish to use. Then click 'Create New World.'
