Query: NOT FOR MAC

I work on 3D design and need my MAC 100% powered upThis is USELESS for MAC LAPTOPS the ventilation from bellow is just not enough. The Fans are too weak, maybe if your laptop has vents from bellow, but you can buy the $15 acrylic ones and get more vents even. The base support blocks any disks from the front so only the side ones work well on this. the ON/OFF button is useless because if you want to turn it off you can just unplug it (and an unused base is even more useless!!)If your MAC heats up just download SpeedFanI havent found any windows driver that can control my MAC Laptop's fans so in Bootcamp it ALWAYS heats up to 80 deg Celc.You get a black painted metal base instead an aluminium colored onethe metal scratches your laptops base unless you place extra rubber piecesIn the end... NOT WORTH IT....
