It's here, dude.

What's that? you want to install an app you didn't get from the app store? Try running it, then get shut down, then open system preferences, then security, then click the button, then enter your password, then close out, then open the app. This is Apple's 5-year-old "fuck you for stepping outside our ecosystem" nuisanceware, and that's on OS X, which is Unix.

I ran a jailbroken Android phone. It was awesome. Except for updating. It wasn't. Download a gig worth of developer kit on the laptop. plug in via USB. Scour the Internet for scripts. bash into the kernel and sudo a frickin' bluetooth update. Have half your apps not work right.

I lost $500 worth of .tifs because Apple decided that Preview was written poorly enough that you could backdoor into the kernel through a malformed image header. So what did Apple do? It rewrote my .tifs so they contained no information. Not "we think this is a problem" not "this sure looks like a 5mb monochrome TIF, is it?" not "we've quarantined these files because they make us nervous" but "yeah, we're gonna replace these with black because fuck you."

If you are seriously thinking that you're having any sort of adventuresome experience on the desktop if you aren't running an alternative operating system you're high. That shit been dead.
