Apple issued its first update for OS X Mountain Lion on Thursday, promising to fix a number of bugs it and some users have found with the new operating system.

"This update includes general operating system fixes that improve the stability and compatibility of your Mac," says Apple on a support page.

Besides improving the stability of your Mac, the update also promises to resolve an issue that may cause Migration Assistant to quit unexpectedly, improve compatibility when connecting to a Microsoft Exchange server in Mail, and address an issue playing audio through a Thunderbolt display.

Other specific fixes include resolving an issue that could prevent iMessages from being sent, addressing an issue that could cause the system to become unresponsive when using Pinyin input, resolving an issue when connecting to SMB servers with long names, and addressing a issue that may prevent Safari from launching when using a Proxy Automatic Configuration (PAC) file.

The OS also gets improved 802.1X authentication with Active Directory credentials.

You can download it via the new Apple Software update tool (App Store basically) on your Mac now if you haven't already received a notification in the notification center.
