Summary: From my experience, when i first used this drive the tray would not coming out when you press the button. Tried this when plugged into the computer about 20 times. .. It makes a spinning noise and then doesn't do anything. i had to put a small pin like a paper clip into the small ejection hole that you see in all CD drives. It allowed the tray to come out. I then tested the ejection of the drive multiple times there after and it seemed to have fixed the stuck tray.
Summary: I had to get a new optical disc drive. My old 1st generation Mac mini bit ths dust and my new Mac mini doesn't come with one. I did some online comparasion shopping and found this one. It had a lot of favorable reviews on several different websites including here (thanks, "Farscape 1"!). I reserved it from MicroCenter.com and picked it up at one of their local Chicago area stores (that's cool being able to do that BTW).
Summary: I bought this external drive to use with my MacBook Air (mid-2011). Plug it in to your USB port, and it just works, no installation necessary. Speed is good, everything works as advertised. As for negatives, the build construction is not the best, as much of the shell is thin plastic, but it's good enough for my purposes. Kind of a weird shape, which makes it slightly less portable. Considering the money you save over buying Apple's external drive, I highly recommend it.
Summary: I bought this burner as a replacement for my apple superdrive. Nothing wrong with the superdrive but I expect that it will quit working soon since I use it A LOT. Anyway, I was looking for a cheaper alternative and this was definitely less costly. The device is bulkier than the superdrive but is capable of all the same things in terms of reading discs and writing to discs.
Excerpt: depuis que mon graveur interne de MacBook à rendu l'âme, j'était inquiet comme c'était mon premier graveur externe, je peut dire que j'ai était surpris et ravi de voir qu'il fonction très bien sur mac, essentiel surtout pour installer leopard, ne vous posez plus de question foncé
