thus far the only shred of OSX compatibility info I've seen is these device IDs, but it hardly a sure thing, and really requires someone with one of the cards to test
"x0a2010de&0xffa0ffff: Code: 0a20 GT200 [GeForce GT 220] [...] 0a2f ? 0a30 ? [...] 0a3f ? 0a60 GT200 [GeForce G210] 0a61 ? 0a62 ? 0a63 ? 0a64 ? 0a65 GT200 [GeForce 210] [...] 0a6f ? 0a70 ? [...] 0a7f ?From:
the GTS 240 appears to be a rebrand based upon the same G92 core as the 8800GT/9800GT, but from what I can gather the G 210, GT 220 and GT 240 are all new 40nm chips using new cores: (GT 215, 216, 218 GPU cores)
My biggest concern is that the reference design for these cards is now a HDMI/DVI/VGA combo, so less chance of proper dual monitor support in OSX, if the cores are even supported at all.
