Apple today seeded OS X 10.8.1 to the public, the first update to Mountain Lion since its release in late July on the Mac App Store. The update can be downloaded from Apple’s website or through Software Update on Mac, which directs you to the Mac App Store for installation. The software update is build number 12B19 and includes the following features and fixes according to the official release notes ahead.
This update includes general operating system fixes that improve the stability and compatibility of your Mac, including fixes that:
- Resolve an issue that may cause Migration Assistant to unexpectedly quit
- Improve compatibility when connecting to a Microsoft Exchange server in Mail
- Address an issue playing audio through a Thunderbolt display
- Resolve an issue that could prevent iMessages from being sent
- Address an issue that could cause the system to become unresponsive when using Pinyin input
- Resolve an issue when connecting to SMB servers with long names
- Address a issue that may prevent Safari from launching when using a Proxy Automatic Configuration (PAC) file
- Improve 802.1X authentication with Active Directory credentials.
The update is relatively small and should take just a matter of minutes to download and install. It is unknown if the update addresses battery problems on OS X Mountain Lion, however, and a fix for that problem might come in OS X 10.8.2. It is recommended that all OS X Mountain Lion users make the upgrade to ensure the most secure and stable experience possible on Mac.
