In tandem with the Mountain Lion GM release, Apple this week rolled out OS X Lion 10.7.5 build 11G22, a new incremental update to the current Mac operating system. Full documentation and other tidbits can be found below.
Having no official release date set, OS X 10.7.5 may well arrive after Mountain Lion is launched to the public this month. However, if history is any indication, Apple will offer 10.7.5 as an upgrade path to all users.
For now, developers are asked to focus their testing efforts on: Graphics performance and quality; Image & Media importing, editing or viewing; and networking reliability & performance.
There are no known issues with this build, which is always reassuring if we are to asses a potential release date.
“This build is being provided to you for testing and development purposes,” Apple tells developers. “Should you encounter any problems, please submit a bug report using the online Bug Reporter at <http://bugreporter.apple.com/>.”
The Cupertino giant asks testers to make sure they include ‘10.7.5 (11G22)’ in the bug title and description, noting that “this information will ensure that your bug is processed quickly.”
“When submitting a bug report, please make sure to include a Summary, Steps to Reproduce, Actual Results, Expected Results, the System Profile Report, and any other relevant information that is necessary to process the report,” Apple adds.
Developers need to be aware that they will not be able to revert back to their previous system after updating, which is why Apple urges them to “install this update on a system you are prepared to erase if necessary.”
The change log also includes some legal notices, including the fact that such documentation shouldn’t really end up in the wild.
Unlike Mountain Lion GM, which can be obtained from the Mac App Store, developers looking to download and test OS X Lion 10.7.5 will have to do so on the Mac Dev Center by logging in with their credentials.
