The Mail application that accompanies Mavericks version 10.9 of Apple's OS X has reportedly had issues. On Friday, the technology giant issued an update for the app, capping off several updates that have been released this week.

The Mail update fixes several issues, including one that prevents users with custom Gmail settings from deleting, moving and archiving messages. There is also a correction for a bug that has caused counts of unread mail to be inaccurate, as well as unspecified, additional fixes that the company said "improve the compatibility and stability of Mail."

To install the 32 MB update, Apple recommends backing up the computer first, such as with Time Machine, and then updating through Software Update under the Apple menu. A manual update installer is available if one wants to update multiple computers with only one download.

MacBook Pro, iBooks

Shortly after Mavericks was released last month, complaints began to appear on the Apple Support forum about the Mail issue.

Recently, there have also been reports that Mail does not appear to remember a password for an iCloud account, and repeatedly asks the user to enter it. Checking the authentication method used by Mail is recommended by some Mac users, in order to make sure it is the same as Apple's default. The authentication method can be found in Mail's Preferences-accounts.

On Thursday, Apple also issued an update for the new MacBook Pro, dealing with an issue where the built-in keyboard and multi-touch trackpad may become unresponsive.

Also on Thursday, Apple released an update of iBooks for Mac, version 1.0.1, which, the company said, provides unspecified bug fixes and performance improvement for the app. iBooks for the Mac was first released with this new OS version, and it allows users to purchase and read books from iBookstore and sync them with other Macs or iOS devices through iCloud.

GarageBand Update

On Wednesday, GarageBand for Mac version 10.0.1 was also issued, to fix what Apple said was "a number of minor issues" with that app and to improve stability.

None of the reported issues with the new Mac OS have been major, and it has had the strongest start of any OS X version. Last week, Web analytics company Net Applications reported that 10.9 percent of all versions of Mac OS X used in October employed the new version, according to its tracking. If accurate, this adoption rate would be triple that of the previous OS X version, Mountain Lion. One factor in the fast pace of adoption, of course, could be that Mavericks is available free of charge.

Mavericks can run on any Mac computer that can run Version 10.8 Mountain Lion, although the machine needs to have at least OS X 10.6.8 Snow Leopard before updating. The new OS features an updated Maps and iBooks app, a new power management scheme that Apple says can reduce CPU usage by as much as 72 percent, enhanced security for apps and browser plug-ins, and a new Tags feature for organizing files in a way that is consistent across Macs and iOS devices.
