Today, iOS 5 was released. With that came some new apps and yesterday’s iTunes 10.5 update. There is also the Mac OS X Lion update, which is two separate updates today. The first is just a Lion update. The second is a recovery update.
Both of the updates are around 400MB each, totaling at 971.4MB of downloads, so it may take a while on some connections.
Added are the iCloud functions, Back to My Mac (remote access to your Mac from any Mac anywhere on the internet) and Find My Mac, which is like find my iPhone, but helps you find your computer should it go missing.
The other update is a Lion Recovery update which is described as “improvements to Lion Recovery.”
