Since I noticed that Mark Finkle’s download slot for XULExplorer 0.4 for Mac was still labeled as “coming soon”, I figured I would whip up a Mac distribution. So I grabbed the source from Subversion and did just that.

Some things I got errors on:
I didn’t see a “tasksOverlay.dtd” file, so I just disabled those entities in “inspector.xul”.
There wasn’t a “venkman-overlay.dtd”, but I found one via Google and slammed that in there.

So I guess this isn’t an “official” distribution, there prolly is some stuff not 100% right. The app bundle directory arrangement might be a little different too, since I slapped the source into my own build process, and created the distribution from that.

Oh, and I used XULRunner 1.8.0.4, what I had laying around. I guess it’s not a UB. If I do this again, the next one will be. (Should still work fine on Mac Intel, will double-check when I get on my Macbook Pro later today)
Update: Works fine on Mac Intel, forgot that 1.8.0.9 gives you a UB, will update this weekend sometime.
Update 2: Now a (fat) Universal Binary

Here it is:
XULExplorer 0.4 - Mac (Universal Binary - 19.2 MB)
