OS X Mavericks: VirtualBox will not start with Bridged Adapter

Update 16 Oct 2013: VirtualBox 4.3 provides a fix. I’ve tried it out, and it does work although we get some warnings about unknown kernel extensions. See this comment: https://www.virtualbox.org/ticket/8940#comment:10

I’ve left the trail of progress here in case you can’t upgrade, or just don’t want to …

Update 8 Oct 2013:  Upgrading to OS X Mavericks GM, ran into some more problems, so I’v been issuing:sudo /Library/StartupItems/VirtualBox/VirtualBox  restartto fix it, see also this VirtualBox ticket : https://www.virtualbox.org/ticket/8940.

Original Post 2 Oct 2013: Just a quick note on OS X Mavericks, I’m using Developer Preview 8, and the fix provided by theengguy worked for me: http://theengguy.blogspot.com/2013/08/virtualbox-and-bridged-network-on-os-x.html

The symptom is that, upon startup, bridged network guest (in my case, both Ubuntu 12.04 and 13.04) throw an error (which I forgot exactly what now, but something to do with the network adapter). It’ll run just fine in NAT mode.

Any way, thanks thengguy, solution worked perfectly!

Git missing in OSX Mountain Lion

Quick one today to remind others and perhaps my future self. After my upgrade to Mountain Lion, git was missing. Surprise!

Easy fix for me, obtained via https://answers.atlassian.com/questions/72981/error-after-upgrading-to-mountain-lion-os-git-svn …  (Thanks!)

In Xcode, we just go to Preferences > Downloads and click install next to “Command Line
Tools”:

Re-installing command line tools, git included!
Hope this helps! It certainly easier to git push when you actually have git 😉

X11 for OS X Mountain Lion

I love trying new stuff, so I went ahead and installed OS X Mountain Lion Developer Preview 4. Of note, X11 isn’t included any more. But that’s actually a good thing – you’ll be using the latest and greatest XQuartz by the time you’re finished. If you’re like me, you’re in a rush to fix some program (like Gimp, for example, which is why I wanted to get this fixed right away), here’s the short story.

X11 Doesn’t Live Here Any More

This is the message you’ll get when you try to run an X11 program, but don’t have X11 because you’re on OS X Mountain Lion. It says you can Continue on to an Apple Knowledge Base Article to get yourself sorted, but all I got was a 404 (and an apology).

You’re sorry? Me, too.

The long and short of it is that you now need XQuartz, which was actually the X11 that we in use in OS X to begin with, but now you’ll have to get directly from the XQuartz site. Download and install and *poof* off you go.
