OSX - What I like

[ #6795 ]

The best thing I like so far about OSX - how you install a new application...

The applications I've seen so far all seem to come as (gzipped) .dmg files. This is a disk image, that OSX natively supports mounting (via loopback fs). So you mount this and you get a new disk icon on the desktop. Open that and you get a readme.rtf and the application icon. Double click the icon and you can run it - play with it a while and if you like it, to install it all you do is drag and drop it into the Applications folder. That's it. The actual application is a directory containing all the resources it needs, but to the OS it just looks like an icon that runs when you double click it. If you want to delete the whole application you don't need "Control Panel, Add Remove Programs, Find Program, Click the button, ok, close Control Panel". You just delete the icon and the whole thing goes away. Nice. Clean. Simple.

For GUI apps this is definitely the way to go. And if you really need to, you can get to the actual binary - it's just in the .app directory somewhere.

  • Twice in 24 hours, I'm mentioning Acorn RISC OS [riscos.com] on use.perl.

    Acorn had a similar format for their applications. Any directory that had a name starting with ! (e.g. !Draw, !TechWrite, !Ovation) was an application. Double-click and it runs !Draw/!Run (although in Acorn parlance, the dirsep is period, so !Draw.!Run).

    This is, of course, where ROX [sourceforge.net] got its layout from. ROX, of course, borrows many other RISC OS ideas, since it's "Risc Os for X", more or less.

    Similarly, image filing systems. RISC OS had a featur

    • It seems to me to be a combination of some of the best features of the Acorn and the Amiga (things like meta-data where the Amiga was very strong). It's nice to see those things making it into a very strong contender in the OS market.

      Now if I can just shut up my whining co-workers who repeat ad-infinitum "Well it's all very pretty, but what can you *do* with it?". Argh - they are so damned annoying. I ask what can't you do with it, and they run off a list of lies (the best one so far being that you can't p
