Hi, I'm sorry it's been asked a lot on here about Thunderbolt and Mini-Displayports, but I can't find the EXACT information I'm after Re: the differences. I have an older MacBook Pro 15" with a Mini DP (NOT Thunderbolt), wanting to connect it to an older Mac (Also NOT Thunderbolt) for an Extended Desktop solution for audio production. I can only find Thunderbolt cables (listed as MDP) for sale, or it's not referenced, or the store clerk knows nothing about what I'm asking! I can't find anything listing the older Mini-DP Male-Male cables... Question is; Does it matter? If they are BOTH older Macs, does is matter if it's not an older MDP cable? Can it be a Thunderbolt cable instead? Help appreciated, Thanks!
