OSX errors: frustrating I might not be able to claim 10.9 support yet. I think I have to limit it (and bug bounties) to 10.8.
The print issue predates Mavericks, I can replicate it on 10.8 in both the latest stable and the latest beta.
I completely understand your reluctance to support 10.9, it's foreign territory especially as you're not a native developer.
