I’ve a 2011, 15″ MacBook Professional (working 10.6.8) with the defunct, AMD(?) graphics chip. I am attempting to hook up with a 23″ Apple Cinema Show utilizing a brand-new Mini DisplayPort to DVI adapter (LogiLink CV0037), however it would not work. I’m conscious that my laptop computer has a Thunderbolt port, not a Mini DisplayPort. Nevertheless, every little thing I’ve learn appears to point {that a} Mini DisplayPort to DVI adapter ought to work completely positive for what I am attempting to do, given Thunderbolt’s ‘backward compatibility’.
The almost certainly wrongdoer in my thoughts is that I’ve completely disabled the defective graphics chip by following these video directions, which could be interacting with how my machine connects with the show. Is that this probably right? Is the AMD(?) chip required to run exterior shows? Are there some other apparent prospects?
Additionally, it is value noting: Each the show and adapter do in actual fact work. I plugged the show into an older 17″ MBP with a mini-DisplayPort with no issues. Additionally once I pull the adapter out of both the 15″ or 17″, the laptop computer display goes blue for a couple of seconds, suggesting that the 15″ MacBook Professional can be detecting one thing, simply not integrating the show connection absolutely(?).
