Apple has just released the latest batch of stability, compatibility, and security updates for OS X Leopard, all wrapped up in the 10.5.3 update. On my Mac Pro, the update is clocking in at 420 MB, so it’s a hefty one. That is understandable though, because there are quite a few fixes in this one. Some that stand out to us include things like improved Time Capsule reliability, screen sharing fixes, and a few Spaces improvements. We’ve got the full list for you after the break, if you are interested. Otherwise, fire up Software Update to get the latest and greatest.
