OSX Mountain Lion Question...

Does anybody know if the new OS can make use of Hyper-Threading?
The current 10.7.4 can't; it only shows 2 cores instead of 4 (2+2 = 2 cores with HT).

Just asking because one thing that caught my eye was that the MacBook Pro I have gets really warm at the bottom when streaming video over wifi.

Thanks

Are you sure your CPU support HT? All 2011 models support it. My 2011 MacMini has 4 virtual cores.

What are you talking about? Mac OS X does understand and makes use of hyper-threading.

If I bring up System Information on my MacBook Pro, it will tell me I've got an Intel Core i7 CPU, that there's 1 2.3GHz processor, and total number of cores is 4. This is all quite correct. There are 4 physical cores in the CPU.

If I go to Activity Monitor and bring up the CPU Usage window, I see 8 graphs, since my CPU has hyper-threading.
