Apple’s eagerly awaited operating system, MacOS X 10.5, also known as “Leopard”, is now in our hands, and there are quite a few features in it that will be interesting to developers. Amazon is still offering Leopard for $20 off list and Leopard Family Pack (5-user license) for $10 off list.

I do limited development on MacOS X. I don’t write Macintosh applications, but I do write web-based applications that I deploy to non-Macintosh servers. The Mac is a great environment for doing this; I get a real UNIX environment under the hood with Apache, MySQL and Perl, and a nice layer of Macintosh over the surface. After years of struggling with Windows and Cygwin, or living with Windows and Linux, it’s been wonderful moving to a single, reasonable environment for working.

Given that, my emphasis on development under Leopard will be on the kinds of tools a web developer might use, rather than XCode, although I’ll touch on XCode at the end.
