There was absolutely no compelling reason for me to update, but I did it anyway. Since then I am plagued with video problems, like can be seen on the small picture to the right.
The seems to be the rare maintenance update that introduces problems. The
-[NSWorkspace iconForFileType:] method now returns generic document icons for me in certain circumstances. Another
NSWorkspace bug leaks memory. Daniel Jalkut is seeing a new UI glitch. I’m seeing PDFView drawing glitches, which for Gus Mueller are accompanied by crashes. The video-related kernel panics that I started seeing with 10.7.3 are still occurring. I’ve also heard of problems with security-scoped bookmarks—introduced in 10.7.3 and essential for sandboxing—no longer working properly. It’s unfortunate that, as we near Mountain Lion’s release, Lion itself is not yet solid for everyone.
