Any suggestions on a Windows Notepad like APP for Mac ? I thought the built in Notes app in the MAC OS X is still not as clean as the MS Windows Notepad.
I would agree that TextEdit with Rich Text Format disabled is a good analog to the Windows Notepad.
At the same time, TextWrangler that myflynn recommended is a good tool. It much more powerful and more like the freeware NotePad++ that is available for Windows, but it might not be simple enough for some applications. I have NotePad, WordPad, and NotePad++ withing easy reach on my Windows machines and both TextEdit and TextWrangler on my Mac's Dock. I find I use TextEdit much more than TextWrangler. It's a case of which took best fits the job at hand. Extra features can sometimes get in the way.
