I currently own SONAR 8 Studio and just purchased a new iMAC - quad core i7, 2 TB hard disk, 16G memory.   I want to know if anyone has had success running SONAR 8 on this type of platform.  Reason is I need to figure out if I buy a copy of Windows 7 and run Sonar via Bootcamp, or go direct to Logic 9.  I would like to leverage what I have learned about SONAR if possible.

need to dual boot windows

But I heard that is not supported by Cakewalk anymore.

I don't know why it wouldn't. It is a normal windows install on your own Mac box. You're not using parallels to appear to be running on windows- you actually are running windows. It should work fine. I'm running Windows on my Macbook Pro with Bootcamp and it works fine with all my windows software.

I'm not sure Cakewalk ever officially supported Sonar on Bootcamp. It works, and many users run it, but it's not officially supported.

I read somewhere that Cakewalk wouldn't work with OSX Mountain Lion.  Just hate buying Windows 7 strictly for Sonar for $219.00 when I can alternative buy Logic Pro 9 for $199.

again you have to dual boot if you want to run cakewalk..
what you should be doing is buying building a windows system and dump that awful apple system and OS.

Depending on what you want to do, and how you intend to use Sonar, the computer choice does matter.  If you are strictly going to be doing live recording, and really want to use Logic, then Mac is the choice.  As has already been pointed out, Sonar will not run under the Mac o/s.  You will need the Windows o/s.

However, if you are intending to use lots of VI's, working primarily with sampled sounds, then, the issues change.  Both VSL and EW have been very straight forward stating that their libraries run better on the Windows o/s than on the Mac o/s.  The Mac simply no longer has the advantages that it used to have.  That can be hard to take for long time Mac users (used to use Mac myself), but for music production, the advantages are very much on the PC side, unless you use Logic, or Final Cut Pro, both of which, obviously, require a Mac.
