first, edit your web server’s httpd.conf (for example, /Applications/MAMP/conf/apache/httpd.conf) and add a VirtualHost with some name other than “localhost” (we do this because windows may reserve localhost for some of its services).
edit leopard’s “hosts” file:
sudo nano -w /etc/hosts
and append your new host name to the existing line for localhost:
127.0.0.1 localhost yourhostname
throw open Terminal. type two separate commands:
defaults write com.apple.dock tilesize -int 64
where you can set the desired icon size to whatever you want (rather than 64). Dock will relaunch with the icons shown in your exact desired size. (if you’re like me, being exact is just what you do.)
