Apple has just released a whopping 730.6MB update for Mac OS X Lion – v10.7.3. As you can see from my measly broadband connection, which is by the way supposed to be a 30Mbps fibre service, the update is going to take another 3 hours to complete. The update which includes Safari 5.1.3 fixes a plethora of issues including using smart cards to log into OS X, compatibility issues with Microsoft Windows file sharing, resolves Wi-Fi connection issue when waking from sleep and includes RAW image compatibility for additional digital cameras. The update also fixes/enhances Directory Services.
