OS X Leopard most welcome changes from a developer’s point of view

- Terminal (tabbed, colors can be changed - dunno if it was possible before)

- Spaces (ctrl + arrow keys very nice)

- php5 (I will still go with macports though)

- ruby and rails (macports needed though) if rmagick was built in i’d be blown away. however this is not the case - you need to compile it for yourself. see my previous entry about it.

- full 64 bit support (even for GUIs!) built in for powerpc and intel. the so called fat / universal binaries can now contain 4 different architectures’ binaries. intel 32, intel 64, ppc 32, ppc 64. Very cool. Just for you to know, the latest macs (the core 2 duos) are 64 bit processors. However in the latest leopard most of the apple apps are supplied in 32 bit version only. that’s not a prblem though - you will not recognize it (everything just works). The Xcode is compiled in 64 bit as well though. You can check it with the ‘file’ shell command or using the activity monitor (last column shows the architecture)

- apache2 built in using 64bits(!) having modules like fastcgi precompiled
