When connecting my Thunderbolt Display to my MacBookPro

 

  Model Identifier:          MacBookPro6,1

 

  Boot ROM Version:          MBP61.0057.B0C

  SMC Version (system):          1.57f17

 

I do not get a display on the Thunderbolt.

 

I have checked the Diplay Settings and the only 2 tabs are DISPLAY and COLOR

I do not have an ARRANGEMENTS TAB

 

When I look for the ARRANGEMENTS TAB I get the message

"The Arrangement tab of Displays preferences is hidden because you only have a single display attached to this computer."

 

I have the Thunderbolt connected to the MagSafe port and to the Thunderbolt port and the Thunderbolt is plugged in to a power source.

 

I have tried the MacBook Pro EFI Firmware Update 1.9 and get this message:

"This software is not supported on your system."

 

Can someone help me or direct me to another discussion

 

Thank You!!


MacBook Pro, Mac OS X (10.6.8)
