After almost 3 months of seeding, and numerous builds, Apple finally released the Mac OS X 10.7.2 update on October 12th.

This is the first major update to Lion (the 10.7.1 update was relatively minor). Mac OS X 10.7.2 includes the new iCloud service, Apple’s replacement/upgrade to MobileMe, allowing users to store up to 5GB of data online for free and wirelessly push it to all of their devices (want more data?… pay a yearly fee).

Although the Mac OS X 10.7.2 update addresses several outstanding issues, including a major LDAP password security problem, after spending a good part of the day reading through the Apple Discussion forums I can safely say there are still plenty of Lion bugs and glitches that need Apple’s attention.

Mac OS X 10.7.2 does offers a lot of interface tweaks with the Finder, LaunchPad, Mission Control, desktop spaces, and full screen apps. It also fixes Mail attachment problems, improves Active Directory integration, comes with a reportedly more stable version of Safari, and the TextEdit app no longer insists on adding .txt to the end of all documents saved. 10.7.2 also introduces the ability to boot into Lion Recovery from a Time Machine disk.

Some of the most active unresolved Mac OS X 10.7.2 discussion threads currently include: Versioning issues with files stored on servers, dual display bugs, Finder file placement and selection bugs, repeatedly dropped Airport connections, Finder sidebar bugs, poor battery performance, problems with Mail connecting to Exchange servers (unreliable connections), and HDMI video issues.

So do I believe Lion is ready for prime time yet?… No, but it’s getting better. Given Apple’s prior track record, and all the third-party app updates that are emerging, I’d guess Lion will be fairly stable at about the 10.7.4 mark… which would mirror when previous OS X releases had moved past the early adopter phase. I do however strongly recommend that you setup Lion on a test Mac within your environment, and begin identifying what does and doesn’t work. You’ll likely find that ALL of your third-party software needs to be a recent release and patched to the latest version, and it’s quite likely you’ll identify quirks or incompatibilities with your network/hardware/apps/printers/workflow.
