No, running spore on a mac will not make it slow, but not meeting the system requirements will make it do close to nothing correctly.
If it is the Mac version of Spore and the Mac has an Intel processor (1.7GHz Core 2 Duo or higher) then the disc will work. If it is a Windows disc then it will not work unless the Mac is running Windows.
spore is out for both mac and pc. (go macintosh!)
For Mac, or PC?
not yet
you cant
The full game of spore is only available on PC and mac, sorry.
yes

Yes. When i buy it say in the information that the game works for mac and pc. So the same game works on both computers. I DONT KNOW IF SPORE GALACTIC ADVENTURES AND SPORE CREEPY AND CUTE WILL WORK TOO FOR MAC.
Creature creature is only on PC/MAC. Spore Creature Creator is now on the Nintendo DS
