Switching to Mac

[Darician]

Moving the files is the easy part. Getting over the fact you've grossly overpaid for identical hardware that has been proven to run Windows 7 faster than OSX....that's the difficult part.

But the OS is not identical. OSX is optimised for some config. Windows must run hundreds of config.
For initial question I think the problem is can we transfer a song file with USB key format in ntfs or exfat ?

I believe Mac OS X can read NTFS volumes so there should be no problem with that.
