I blame EU expansion… they seen expansion slots and took them all. This is the real reason for a lack of expansion capability in the latest Mac Pro.You don't care who's right, but you want Apple to simply make it work while the EU is specifically trying to make it not work?
Let's see...this will work in countries that aren't in the EU. So, Apple can make it work. Just not in the EU. The common denominator is: The EU.
The fault lies squarely on the EU.
There is a negative correlation between EU expansion and Mac Pro Expansion options. The biggest blow was RAM expandability. Now they have issues with DMA. EU keep your hands off our direct memory access! Was it not enough that you took away our right to install more RAM? Now you want to take away all our access!
