Hey, just ALL sites have a page full of links, some of them are very boring, but that's the Web !

• Ibrium HB home page, authors of MacDim.
• Lloyd's screensavers, a must-see.
• Metrowerks, makers of CodeWarrior, my favorite C/C++ compiler.
• Apple (obviously).
• Macity, an italian Mac news page, very good.
• Cocoa Dev Central, serving Cocoa Newbies.
• Versiontracker, for the "I always need to be up-to-date"-man
