There an interesting debate which is going on since many years about how Mac apps should be distributed an installed. Back in September John Gruber wrote this interesting piece, outlining the pros and cons of three popular formats of delivering Mac apps: .zip, .dmg and installer. He was inspired by this post where Alexander Limi (founder of Plone, working at Mozilla now) discussed the problems of the installation process of Firefox on the Mac platform.
In this post I’ll discuss all the possible scenarios, referring to other articles found on the web to give you my idea of how Mac applications should be distributed.
