Dear Mr. Jobs: I've come home. My new Mac (with Mountain Lion) is up and running. I'm ready to go where ever the Apple Road takes me... ...but I need advice from the QRZ.com wizards. The objective is an antenna modeling app. Which approach is preferred by those wizards: (1) EZNEC by W7EL operating in Windows via the VMware Fusion virtual desktop; or (2) CocoaNEC by W7AY for Mac? Note to QRZ.com wizards: no need to channel Mr. Jobs, you may post here.
