Apple has released it’s first OS update for Mavericks, bringing it to version OS X 10.9.1. The update is available in three separate installers: One for late 2013 Mac Pros, one for late 2013 Retina MacBook Pros, and a generic version for all other Macs running OS X 10.9. The first two model specific installers include undisclosed “system-specific enhancements and fixes”.
The majority of the issues addressed by the OS X 10.9.1 update are with Apple Mail, including: better handling of POP accounts, improved support for Gmail accounts, fixes for users with custom Gmail settings, improved reliability of Smart Malboxes, improved searching capabilities in Mail, and a fix that prevented contract groups for working in Mail.
OS X 10.9.1 also includes Safari 7.0.1, which is reported to fix an issue where Safari hangs when filling out some online forms, and provides improved VoiceOver and credit card autofill capabilities.
In my opinion OS X 10.9.1 is a relatively minor update, and is safe to apply if you are already running OS X 10.9. I have begun pushing out to the Mac workstations in the Chicago market under All Covered Contract.
