Hi Guys, I'm a first time mac user. My system is as follows: iMac 2.4GHz Intel Core 2 Duo + 3GB DDR2 SDRAM. I am running OS X Version 10.5.2. Recently my iMac decided not to spit out a client's CD, I've tried everything to get it out but in the end I sent it for repair and this happened just after my warranty expired. Applecare wants to bill me $300 for a new DVD drive but I'm skeptical about getting my client's CDs stuck in this type of slot drive again. They billed me $90 for the CD removal, and I went out to get an external DVD writer, one that would at least have a tray and an emergency eject button. My choice was the Buffalo Portable DVD (DVSM-PN58U2VW) also known as the Buffalo MediaStation 8x Ultra-Slim Portable DVD Writer I've checked online prior to purchase and was assured that this is a MAC/PC compatible drive. When I plug it in to my iMac, the drive (USB powered only) cannot be detected but the drive lights are on and the tray can be ejected, I'm sure there is nothing wrong with the drive as I've plugged it into my windows xp laptop and have already burned a few DVDs. There were no drivers needed to be installed and there were no drivers in the accompanying CD. Please help I'm in quite a fix. Thanks!
