Can I upgrade Core i5-2400S to Core i7-2600?
it is possible upgrade Core i5-2400S to Core i7-2600?
You can upgrade the 21,5" with the i7 2600S
As long as both are the same mount...
*After some googling*
They are both LGA 1155, so yes, it can be upgraded.
OS 10.6.7 has to be able to support the intel core i 7 2600... google that first
