How come my VM can figure out what CPU I have...

[InsanelyOne]

As you can see from this screenshot, my Windows VM (running under Fusion) detects the CPU correctly, but ATM doesn't. I also recall running a command (which I have forgotten) in Terminal that listed my system info in OS X and it also displayed the correct CPU info.

 

I was hoping someone might be able to enlighten me why ATM / System Profiler requires hacks/patches to get things right. (I understand there are a zillion threads with people complaining that ATM shows incorrect info. I was hoping to get some help on understanding why and maybe learn how to hack ATM/System Profiler myself.)

 

 

EDIT: The command I was thinking of is "sysctl -a". When I run this command, I do see the correct CPU info (as well as some incorrect info):

Also, I ran Colonel's System Profiler Patch 1.3.5 and I still get "There was an error while gathering this information." in the Hardware section of System Profiler.

This is because the ATM window/System Profiler doesn't know what a Pentium D is. They don't COME with Pentium D's. Naturally Apple wouldn't waste their time adding lines of code in their software referring to Pentium 4's, Pentium D's, etc.
