Today, Apple has begun seeding new versions of OS X Mountain Lion, iTunes, Safari and Java to Apple employees. The new OS X build is version 10.8.5, and it is a supplemental update to the version that was publicly released last month. Last week, we noted that Apple was preparing this new version with bug fixes for MacBook Airs, USB, and HDMI, and today’s new seed is a higher build number (12F45 versus 12F42). This indicates that Apple is making progress on the release and that the launch is nearing for customers…

In addition to the new 10.8.5 release, Apple has provided its employees with Safari 6.1 build number 537A134. This Safari release for Mountain Lion brings feature parity to the version coming with OS X Mavericks later this month. The new Apple web browser will add Shared Links (a way to quickly manage links in your Twitter and LinkedIn timelines), a new sidebar, improved power savings, third-party data blocking, and increased search engine options for users in Russia. This Safari 6.1 release has been available to developers for the past several weeks. 


Also provided to Apple employees is iTunes 11.1.1. This upcoming update is a bug-fix release for the recently launched iTunes 11.1. iTunes 11.1 brought iTunes Radio to the Mac, and 11.1.1 will improve stability and fix bugs relating to Podcast management and iTunes Extras.

Besides the OS X and application updates, a new version of Java is also incoming with improved security, reliability, and compatibility.

With these updates now being in the hands of Apple employees, it is likely that they will hit the Mac App Store for customers in the coming days or weeks.

  1. Good. My camera does not work with Skype on my MacBook Air.


  2. will they improve tunes library to be on NAS or something. this so far i s awfull, especialy since it grows like crazy, with new movies etc…


  3. My iMac has both a factory SSD and an HDD built in and the hard drive has been spinning down with a clunk, then spinning up, down with a clunk, etc for a while now. It doesn’t do it when it’s being used, just when it’s sitting idle on my desk. Drives me nuts.

    I’ve seen people on The Internet™ talking about similar issues but they always mention external drives. Maybe because there just aren’t that many Macs with more than one internal drive these days?

    Sounds like they fixed this in 10.8.5 then?

    Lately, I am encountering some heat up issues on my mid-2013 MBA. I hope this update will fix the issue before OS X mavericks get released in public.


  5. sweet I was wondering why I can’t make video calls on skype anymore. The OS X team has always been great.
