Apple Preparing Employees for OS X 10.8.5 Launch with New Prerelease Build 12F35

by

mountain_lion_iconApple appears to be nearing a public launch for OS X 10.8.5, with MacRumors receiving word that the company has seeded a new prerelease version to employees. The prerelease version arrives as build 12F35, and increment of two builds since the most recent developer seed just over two weeks ago.

According to a source, the build includes final release notes for the update, highlighting fixes for Mail, AFP file transfer performance, screen savers, and Xsan.

-Fixes an issue that may prevent Mail from displaying messages
-Improves AFP file transfer performance over 802.11ac Wi-Fi
-Resolves an issue that may prevent a screen saver from starting automatically
-Improves Xsan reliability

While a prerelease build for Apple employees is frequently indicative of an imminent public launch, it is not always the case. As was seen with OS X 10.8.3 back in early March, Apple issued a prerelease build to employees but then elected to distribute a new developer build roughly a week later with a public release following two days later.

This isn't really a big deal, especially since 10.9 is coming.

Some people might not want to pay to update 10.9.
