Mavericks, a new operating system recently released by Apple, is a free software download for Mac users.
Some basic details about Mavericks are:
- Mavericks will run on Apple computers from 2009 and later, although it been known to work on Macs from as far back as 2007.
- Mavericks requires at least two GBs of RAM.
- The installation of Mavericks on a MacBook Air, MacBook Pro or iMac may take 2-3 hours.
You may not feel the effects of Mavericks power saver features without a brand-new MacBook Pro with Intel’s Haswell chip, Using Mavericks on a Mac with a processor built before the current Haswell chip may only increase the battery life incrementally. The combination of a new MacBook Pro and Mavericks will give results more in line with Apple’s statement on expected battery life, of 7 + hours.
Some Mac users have run into issues of Mavericks taking a very long time to install, sometimes even over 2 hours. However, if the OS X Mavericks installation progress bar stays constant for an hour or two and it does not finish, you can try doing quitting the Mavericks installer. Then restart your Mac and try the installer one more time once you reboot.
If you restart your Mac and you do not boot to the desktop but you find that your Mac has stalled Mavericks installer with no operating system to use behind it, you can try performing a force-reboot of your Mac. You can do this by pressing and holding down your computer’s power button, then power it on again.
Warning: This could result in you having to reinstall OS X entirely. If you need to reinstall OS X from your Mac’s recovery partition, you will need to restart your machine while pressing and holding the Command and R keys after your hear the boot-up chime. Once you have OS X up and running again, you can try the Mavericks install another shot.
Time Machine Issue
Some Mac OS X Mavericks users have reported problems involving Time Machine. Some users have said that installing Mavericks has resulted in this error message: “This disk is used for Time Machine backups.”
To resolve this issue, all you have to do is open System Preferences in Mac OS X, open Time Machine and switch Time Machine from On to Off. At this point you can try installing Mac OS Mavericks again and the Time Machine error should not appear again.
As with every newly released OS some Mac users are reporting that Mavericks has a few bugs. Here is a list of what to watch out for after upgrading to Mavericks:
Some Mac users experienced Desktop Mail client and Gmail not loading properly through the Mail app.
Apple has recently released an update for Mail in Mavericks.
Apple’s recent Update for the Mail app in Mavericks includes improvements to the overall stability and compatibility of your email with Gmail as well as:
- Fixed problems with deleting, moving, and archiving messages for Mac users with custom Gmail settings
- Addressed inaccurate unread email counts
Mail does not remember iCloud password
First noted by TUAW this issue occurs after updating to Mavericks, Mail no longer remembers your iCloud password. To fix this problem, go to the Accounts tab of Mail’s Preferences and click the Advanced tab. From here, check the Authentication menu. Change the active selection to Apple Token. Apple uses secure Tokens as a way to access iCloud without having to use your password, by providing your username and password to the app over an encrypted SSL connection.
External Drive data loss
First noted on MacFixIt, some third-party external drives may not be compatible with Mavericks. The software included with these third-party external drives does not work properly with the new Mac OS. Mac users, who have used the WD Drive Manager and similar third party external drive utilities to configure the drive for Mountain Lion and previous versions of OS X, may experience the external drive reporting that it is empty, with no data after upgrading to Mavericks.
Steps to Resolve External Drive Data Loss:
- First, be sure to back up your data up to at least one additional location.
- Check to see if the drive manufacturer has released a software or firmware updates to be compatible with Mavericks’.
- If there is a new update for this, back up everything on your drive just to be safe, then install it, this should resolve the issue and result in no data loss.
- If this does not fix the issue or your drive does not have a compatible update yet then, you will have to find another drive that is compatible or reformat your external drive using Disk Utility, and restore the old OS from a Time Machine backup.
Movies Do Not Preview
After upgrading to Mavericks some Mac users find that .mov movie files no longer show up in QuickLook. Chris Breen at Macworld explains that the problem is a result of Mavericks being “very particular about the kinds of movie codecs it allows,” in order to remain compatible and run properly with Mavericks. Unfortunately there is currently no fix that allows you to view the unaltered movie file via QuickLook, you can still view the movie in QuickTime X, although only after you convert it to a compatible format. To open and view a movie without converting it, you can still use the older QuickTime 7 Pro.
These problems could possibly be worked out as application developers update their software to use Mavericks’ new APIs. Or Apple could fix these issues via OS X updates (version 10.9.1 is being tested by developers now).
