Not really old ones, but maybe like a year prior, yes.
No, but Minecraft does work on Macs.
Minecraft is made to work with ANY computer that uses java.
24 times then is work
It doesn't work on all computers. Try changing the key.
Refurbished computers are different from used computers since they are tested before they are resold. The company that made them will test and inspect the computers to be sure they work to their professional standards. These tests may include the checking of motherboards and memory. But dents or scratches on the outside of the computer will not be repaired.
Maybe you're having technical difficulties. Call a technician. Edit by Ozaicanyousee. There are some computer in witch minecraft will never work. The maximum percent of minecraft success are Mac or ALIENWARE I have ALIENWARE, one of the fastest computers :)

Most digital cameras are made to work on both PC and Mac platforms. To be sure, check the compatibility on the product details before purchasing.
I'm not sure if you can if your lucky you might be able to change the settings and stuff or just find a computer that works with it.
Minecraft should work none the less in May of 2013, try hitting "Options" on the launcher before logging in. Then hit "force update" and it should fix some to most of your issues.
Minecraft 1.4.6 mods will work with 1.4.7 sense they are both a 1.4.
Are you sure they are compatible with Minecraft 1.6.4? You'll find that resource packs will only work with the update they are made for, so a 1.3.2 resource pack won't work with a 1.6.4 pack, for example. Another solution would be to see if you are running Optifine or MCPatcher, these allow minecraft to properly run HD resource packs
