They are close, not as good as Notepad++ but think they’ll never port it over Mac OS X. I got Parallels to run windows on my macs in a virtual machine and forced to use Notepad++ that way. A pain and expensive and enjoy it but more and more using, teeth bashing and grinding, Coda since I like to stay Mac native. The download is a 14 day free trial so see if it fits you. If only everyone would come to love macs and OS X, but I digress…
