To those Mac users who updated too early, patch (still nobody knows when it will be released). In the meantime the user KJK555 from a forum suggested to replace ATS.framework and submited an unofficial patch: https://discussions.apple.com/thread/2792142?start=300&tstart=0 http://azlist.info/kj/downloads/ I didn't test extensively (you need to apply it at your own risk), but some of my documents that were causing me problems now print fine***. Mojca PS: ***Before I discovered the patch I had to reinstall all of my printers an hour ago, (and one of them is still causing me problems and just prints out "error courred = -50", but that might be driver's fault). While I was trying to print a slightly bigger image Mac has consumed approximately 6 GB of disk space while I was away and of course it didn't print anything (it didn't finish). But it did more fun than that. It *removed* all the printers from my settings and God knows what other harm did it do to OS and file system in addition to it. It may not be very healthy to run out of disk space, but removing all the printers from the list is not the nicest and most efficient resolution that OS is supposed to do either.
