HOW TO CONNECT A IMAC 2010 WITH A THUNDERBOLT SCREEN

2010 iMacs being Mini Display Port outputs are not compatible with

Thunderbolt displays. Thunderbolt Displays can only be used with

Thunderbolt equipped Macs.

There was a big fuss over this when the TB display was first released

that it wasn't compatible with Display Port Macs.

is there an adapter to link miniport with a thunderbolt connection ?

As I said, Thunderbolt Displays can only be used with Thunderbolt Macs, period.

There are no adapters, no workarounds, or magic wands or incantations to change that

fact.

Use a Thunderbolt cable and follow Apple's instructions in Use external monitors with your Mac

I'd like to correct myself, you cannot connect a Thunderbolt Display with a non Thunderbolt Mac. My apologies for misleading you.
