So, I purchased a MacBook Air and Mac Mini. Fully switching from the wonderful world Linux, to the adult world of paying for stuff that works without hours of tinkering.. I instantly fell in LOVE with OS X. After using my Mac Mini, I've noticed (from watching activity monitor) that hyperthreading is not used as much with OS X as Linux. I chose the i7 2.3Ghz Mini. Even with CPU use in the 90% range, I rarely see the four virtual cores in use. Every now and then I'll see it chart like 10%, showing OS X is hyper threading something. It seems Linux always distributes load evenly on my i7 2600K. Was it a waste to get an i7 w/ OS X???? Or does OS X just dedicate the hyperhtreading for hypertheaded applications (which I have not used yet)??? I know even in Windows HT was used by the O/S as well as its applications. Just a question of curiosity. P.S. Tried both Mavericks and Yosemite Developer's beta.
