My installation of Snow Leopard is reporting that I have 1.75GB of memory under the pie chart representation in Activity Monitor. It seems that Snow Leopard is using more wired memory than the Leopard, making it unavailable to the system. I do understand that the Snow Leopard build I'm using might not be the final one, but I've found other users experiencing this throughout the web without any resolution/explanation. So what do you think? Is anyone else here using Snow Leopard having less RAM being reported in Activity Monitor? Is this a bug, or is the RAM being used by the OS? PS. Yesterday I posted this thread here but a moderator merged it with the thread I'd posted in the MacBook Pro forum. If this is felt to be necessary in this thread, I'm sorry. However, I do believe that the place for this thread is in the Mac OS X forum. The thread in the MBP forum was posted when I thought that the problem was with my MBP but it now seems clear that the problem is with Snow Leopard, hence the different threads (And if the threads were to be merged, it'd make more sense to merge the other one into this, in my opinion).
