I have a mint condition Kanex adapter that will allow you to plug your 30" Apple Cinema display into any current Mac.
I had this when I owed a a Cinema Display myself and a Mac Mini. Since this setup is long gone, I would like someone else to have the benefit of this adapter without paying full price for one
It was $100 and I had to special order it.
If you want to make sure it works, I'm happy to come over so you can see for yourself.
The Apple dual-link adapter is $109 plus tax. I'm willing to let this one go for $60.
Please message me with any questions you have
