New operating systems always bring new problems, and Mavericks is no different. The Migration Assistant in Mountain Lion had a tendency to crash while copying over your files, while other Macs with the OS dropped Wi-Fi after waking from sleep. The Mavericks update seems to have gone smoothly for most, but it's far from trouble-free. Big issues like flickering USB-attached displays and QuickLook being anything but quick will have to be addressed by Apple. But there are also a number of problems that can be fixed -- or at least worked around while Apple cooks up an update. Here are some of the biggest annoyances Mavericks users are currently dealing with and how to fix them. We'll update the list as new issues arise.

Open up Launchpad to get the current status of the download. There you'll see the Mavericks download with a grayed-out icon and its current status. If it says Paused, just click on the icon to continue the download. If the download still isn't working, launch Launchpad again and locate the Mavericks update. Instead of clicking to resume the download, hold down Option and the app icons will begin jiggling like they do in iOS. Click on the tiny x that appears on the Mavericks update to delete the download. Head to the App Store and start the download over. This seems to work for most users. Photo: Ariel Zambelich/WIRED

Gmail's IMAP Wackiness Gmail's IMAP implementation has always been a bit odd. Now Apple has updated the way Mail works with Gmail's weird IMAP implementation for the better. But if you've tweaked your Gmail IMAP settings before you updated to Mavericks expect some odd message behavior. With All Mail tuned off for IMAP, when you move a file out of the inbox, it just reappears in the inbox later. Not exactly conducive to inbox zero. To get your correspondence back on track, you're going to need to turn IMAP back on for All Email. To make the change head to your Gmail account in your browser of choice and navigate to Settings > Labels > and turn on Show in IMAP for All Mail under System Labels. Now moved messages stay put. Note, however, that your emails will now be downloaded to your computer. So if you're short on space, you might consider using Gmail's web interface for the time being. Now if you haven't had any issues and you have never adjusted your Gmail settings. Just back slowly away from the settings and continue using Gmail as you always have.

Scrolling Broken in Chrome and Other Apps For some folks the ability to scroll up and down a site has been disabled in Chrome after upgrading to Mavericks. If Google's browser is your vehicle to navigate the Internet, this is going to put a stop to that immediately. There are currently two ways to fix the problem. The first is the scorched-Earth solution of deleting and reinstalling Chrome on the offending computer. The second, less drastic, method is to make the scroll bars visible at all times. In the Finder, navigate to System Preferences > General > Show Scroll Bars > and click Always. This will bring the scroll bars back and seems to fix the issue not just with Chrome but with other applications that have stopped scrolling.

Mail Won't Remember Your Password There's nothing more frustrating than putting in a password and having an app or service immediately forget that password. This is doubly irritating if you use a very long alpha-numeric string to thwart would-be hackers and snoops. If Mail keeps forgetting your password every time it starts up, head to the Menu Bar and select Mail > Preferences. Click on the Accounts tab. Select the iCloud email account you're having issues with. Select the Advanced tab. Under the Authentication drop down, select Apple Token.

Slow and Stalled Restarts and Shutdowns Shutting down the computer seems like the easiest feature to get right. But for some (including me), it's become a patience game as the computer gets stuck on the grey screen prior to a full shutdown. To get your Mac back on track without resorting to holding down the power button until it shuts off you'll need to hop into the Terminal and make a few changes. Copy and paste the commands below one at a time. After the first command, you'll be prompted to enter your password. sudo defaults write /System/Library/LaunchDaemons/com.apple.coreservices.appleevents ExitTimeOut -int 1 sudo defaults write /System/Library/LaunchDaemons/com.apple.securityd ExitTimeOut -int 1 sudo defaults write /System/Library/LaunchDaemons/com.apple.mDNSResponder ExitTimeOut -int 1 sudo defaults write /System/Library/LaunchDaemons/com.apple.diskarbitrationd ExitTimeOut -int 1 sudo defaults write /System/Library/LaunchAgents/com.apple.coreservices.appleid.authentication ExitTimeOut -int 1 After you've run all these commands in the Terminal, open up Disk Utility from /Applications/Utilities folder. Select the drive you've installed Mavericks on and select Repair Permissions. After Disk Utility is finished, you should be able to select shutdown and restart with no more lagging or stalling problems.

Quickly Update Shared Links in Safari Apple added a Twitter/LinkedIn client to Safari. Unfortunately, that client, known as Shared Links, doesn't auto refresh and there's no how-key combination to update your feed. That's a huge misstep for anything that pulls content down from the news heavy (and always updating) social networks. The good news is you can create your own shortcut using the Keyboard system preference. Open System Preferences and click on the Keyboard setting. Click on the Shortcuts tab. Select App Shortcuts then click on the + symbol. In the Application drop down select Safari. In the Menu Title text field you need to add Update Shared Links exactly as it appears in the View drop down menu in Safari. Now choose a keyboard shortcut combination. I chose Command+Shift+R. Command+R refreshes a webpage so adding shift to update the Shared Links seems natural. Click on Add and you're done. Head back to Safari and try your new shortcut out.

A while ago Apple updated its Airport Utility and removed some features that many networking power users found to be particularly helpful including multicast rate, the ability to set up an LDAP server, and IPv6 settings. Up until Mavericks, the powerful, but old, Airport Utility 5.6.1 worked great for these networking pros. But, the big-wave update washed away backwards compatibility to the older utility leaving many with the less powerful current version of the Airport Utility 6.3.2. Thankfully, Corey J. Mahler posted not only a fix to bring the old-school utility back into action, but also a downloadable launcher app so you don't have to mess with system files. Mahler notes that you might encounter with Apple's Gatekeeper security feature the first time you launch his app. The feature is meant to keep you from accidentally launching malicious apps. If OS X says it won't load the launcher app, head to System Preferences > Security & Privacy and click on the General tab. At the bottom of the window you'll see an Open Anyway button in relation to the Airport 5.6.1 Launcher.app. click that and you're good to go. Just remember to use Airport 5.6.1 Launcher when you need the power of the older Airport Utility. The best part is that you can have both Airport utilities on your computer so you can determine which one works best for your current problem. Choice is good.
