Screen distortion after upgrading to mavericks os

I own a late 2011 MBP 13". Last week I upgraded to Mavericks and regret it ever since. Firstly, it's become unbelievably slow. Secondly, and most importantly my screen resolution is now distorted and completely messed up. Immediately I suspected if Mavericks had screwed some setting. So I looked up Google for screen distortion after upgrading to Mavericks. The results were surprising! There are many apple discussions going on about the same thing. After reading most of them, as suggested in almost all threads, I took my laptop to the service station. The initial response given to me was that they suspected a hardware issue. All threads had indicated what to expect so I was not surprised. I explained to them clearly that there are discussions revolving around this topic and many users have been affected because of this. I even showed / shared the links of the various discussions on this topic. The service station in India asked for more time to investigate further. In the mean time I contacted the Indian call centre to report this problem. The service station reverted after their investigation that my logic board was corrupted and needed replacement. Phew!!! The cost of replacement is as good as buying a new MBP. It's really amusing because my MBP is less that 2 years old and unfortunately I do not have extended warranty.
Has anyone facing the same issue been able to convince apple that this is a mavericks issue? Does even apple recognize this as an issue in the first place? Does apple expect people to blindly invest in hardware just because they have released a new OS?
These and many more questions....
Expecting answers!!!
Not a good start to 2014

The startup disk may need repairing ...
Restart your Mac while holding down the Command + R keys.
From there you should be able to access the built in utilities in OS X Recovery

MBA screen randomly freezes, locks up after upgrade to Mavericks

Sometimes my MacBookAir5,2 freezes, not allowing any input from the keyboard and trackpad (I don't use/have a mouse) except for the power key to force quit it. It happens AFAICT randomly, maybe while I'm browsing. In this case there're no crash reports or related messages in Console.app by the time it locks up.
Other times it freezes and WindowServer crashes and I'm logged out. For that you can check the reports below.
I don't know if both problems are related. This all started when I moved to effing Mavericks from Mountain Lion (which was pretty solid and I'd probably return to).
I reset the SMC a couple of times to no avail. Any hints as to what could be causing it or how can I further troubleshoot this problem?

I agree with Bob, run EtreCheck and post the results here.
A couple of questions. You mentioned resetting the SMC, have you tried zapping the PRAM? If not, you can do this by:
Shutting your Mac all the way down.
Restarting your Mac and immediately pressing the Command-Option-P-R keys simultaneously. Make sure you press the keys before the gray screen comes up.
Hold those keys down until your Mac reboots again and you here the startup sound.
Let go of the keys so your Mac reboots as per usual.
Also, how long after upgrading to Mavericks did this problem start?

Can't log in after upgrading to mavericks

After upgrading to Mavericks, I at first seemed to lose the 2nd HD (all data), then list the ability to log in
Help!

If the user account is associated with an Apple ID, and you know the Apple ID password, then maybe the Apple ID can be used to reset your user account password.
Otherwise*, boot into Recovery mode. When the OS X Utilities screen appears, select
Utilities ▹ Terminal
from the menu bar. In the window that opens, type this:
res
Press the tab key. The partial command you typed will automatically be completed to this:
resetpassword
Press return. A Reset Password window opens. Close the Terminal window to get it out of the way.
Select your boot volume ("Macintosh HD," unless you gave it a different name) if not already selected.
Select your username from the menu labeled Select the user account if not already selected.
Follow the prompts to reset the password. It's safest to choose a password that includes only the characters a-z, A-Z, and 0-9.
Select
 ▹ Restart
from the menu bar.
You should now be able to log in with the new password, but your Keychain will be reset (empty.) If you've forgotten the Keychain password (which is ordinarily the same as your login password), there's no way to recover it.
*Note: If you've activated FileVault, this procedure doesn't apply. Follow instead these instructions.

Why did my mouse stop scrolling after upgrading to mavericks?

I have completely lost all ability to scroll with my Apple Magic Mouse after upgrading to Mavericks.   Why did this happen?   How can it be fixed?    It worked fine with Snow Leopard and Mountain Lion.

Everyone:
I was able to solve my own problem, after scouring the Internet looking for solutions. Sadly, the Apple Support Community was of no help.
Here's the full story:
I originally had purchased my iMac with Snow Leopard installed.   I loved it just the way it was, and really did not ever want to upgrade. However, I've been around computers long enough to know that I would HAVE to do it someday, only because of the age old problem of wanting to run some new application in the future, but not being able to, becasue the app would only run on the latest version of OS X. I reluctantly upgraded to Mountain Lion less than a year ago, without too many problems -- nothing I wasn't able to fix fairly easily anyway. When Mavericks came out, with the "offer I could not refuse" price of FREE, I knew I would eventually have to install it.
So the day comes when I'm finally ready to install Mavericks. To get ready for that day, I did the following:
I ran CCleaner on Mountain Lion to clear out any old files accumulated. (No longer works in Mavericks)
Made sure my Time Machine backup was up to date
Cleared out gigbytes of old files off my hard drive, and archived them on an external USB drive
Made sure every single app on my iMac was fully upgraded.
Made sure Mountain Lion itself was fully upgraded!
I then set aside a full day for the upgrade, knowing full well how long it could take, even with a very fast internet connection. Eventually I worked up the courage to go to the App Store, and proceded to download Mavericks.
The update seemed to go smoothly enough, no problems that I noticed. So I finally get to the point where I can sign on to my iMac again, opened up the Chrome browser, and found out that my mouse was was unable to scroll. I then opened up Firefox and Safari, and found that I could not scroll pages on those browsers either. As a matter of fact, I couldn't scroll using my mouse no matter what app I tried. That feature was completely lost.
I went to ' System Preferences --> Mouse ' to look at the settings, and only the most basic settings were available: click and speed, nothing at all for scrolling or swiping.   That's not good....
Looking to see if anything else was missing in System Preferences, I saw that there was no option for Blue Tooth at all. As a matter of fact, Blue Tooth was completely inoperative, and there was literally nothing I could do to make it work. The Mavericks upgrade had completely trashed Blue Tooth on my iMac. I have no idea how my wireless keyboard and Magic Mouse were even operational, Apple must have some sort of "back door" that keeps those two connected even when the entire Blue Tooth subsystem is off-line.
Since there was absolutely no way to fix this, given the damage done by the Mavericks upgrade, my only choice was to do a complete re-install of Mavericks. I did this by turning off my iMac, and then after turning it back on, I held down the command + R keys to initiate the "recovery" of my iMac, and re-installed Mavericks. There are screens the are displayed that walk you through the process, which is fairly easy and strait-forward.
This above process is a feature called OS X Recovery, and it has been present since Lion. Here's a link to an article that explains it more fully:
OS X: About OS X Recovery
http://support.apple.com/kb/ht4718
I did not know about this feature, but found out about it after doing various web searches in an effort to find a solution to my problem.
So, I basically ended up installing Mavericks a second time. This took hours to accomplish, but it worked.   After the second installation, I signed on, and sure enough, Blue Tooth was back in operation, and my Magic Mouse worked without any problems what so ever. I had full scrolling ability in all my apps.
So OS X Recovery saved the day, at least for me.
I should note that before doing the Mavericks upgrade on my iMac, I had already performed the upgrade on a family member's MacBook, without any problems encountered at all.   They were still running Snow Leopard, the orignal OS that came with their MacBook! Like me they were reluctant to upgrade, but eventually it becomes a necessary evil.
Here's hoping that this information may be of use to someone in the future.

After upgrading to mavericks, i cannot open mac app store, preview, calendar, etc

Why i cannot open mac app store, preview, calendar, software update, etc after upgrading to mavericks? How can i fix this? please help me

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, or by corruption of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

Mac Pro never sleeps after upgrading to Mavericks

Hi Folks
Just realised that after upgrading to Mavericks from Mountain Lion, my Mac Pro never goes into sleep mode after the time set for it in System Preferences > Energy Saver.
This never happened with Mountain Lion.
Any body here having the same issue?
FYI - This is a 2012 Mac Pro having duo 6-cores, 64 GB RAM, 1 x SSD and 3 x HDD.
Thanks you for your comments.
B

Test after each of the following steps that you haven’t already tried:
Step 1
Take all the steps suggested in this support article. That's the starting point for any further effort to solve the problem. Skipping any of those steps may mean that the problem won't be solved. Note that, as stated in the article, the computerwill not sleep if Internet Sharing is enabled.
Step 2
From the menu bar, select
 ▹ System Preferences ▹ Accessibility ▹ Speakable Items: Off
Step 3
Select
 ▹ System Preferences ▹ Bluetooth ▹ Advanced...
and uncheck both boxes marked
Open Bluetooth Setup Assistant at startup if...
Step 4
Reset the SMC.
Step 5
Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Safe mode is much slower to boot and run than normal. Don’t launch any applications at first. If sleep still doesn’t work properly, back up all data and reinstall the OS. After that, if you still have the issue, make a “Genius” appointment at an Apple Store to have the machine tested.
If sleep now works as expected, go on to the next step.
Step 6
Still in safe mode, launch the usual set of applications that are running when you have the problem, including your login items, one at a time, testing after each one. Some applications may not work; skip them. You might be able to identify the cause of the problem this way.
Step 7
If sleep is still working after you’ve launched all the usual applications, reboot as usual (not in safe mode) and test again. If sleep still works, you’re done, at least for the moment.
If you still have the sleep issue after booting out of safe mode, post again.

After upgrading to Mavericks, my computer no longer recognizes my ipod.

After upgrading to Mavericks, my computer no longer recognizes my ipod. Screen lights up when it's plugged in, but it doesn't get to the "connected" state and it doesn't show up on my computer, in the /Volumes folder or in iTunes. This has only started happening after I upgraded to Mavericks.

I should also note, that I have restarted my computer and ipod multiple times and have attempted restarting the SMC on my mac, as per
http://support.apple.com/kb/HT3964
all with no luck.
Also, I have updated to the most recent version of iTunes and have checked that the USB ports are being read correctly through the System Profiler. I have also plugged the ipod into the same ports that worked with my keyboard and mouse, with no different results.

After upgrading to Mavericks, F14/F15 brightness adjustments don't work

After upgrading to Mavericks, F14/F15 brightness adjustments don't work. The screen appears to be "locked" at the dimmest brightness level. How do I adjust the brightness?

I am home now and I just confirmed that I have a brightness control slide in my Sys Pre---> Display. However, this for my Apple Cinema display. When I was using another name brand, this wasn't available to me. Nor could I use F1 and F2.
I also went to Sys Pre---> Keyboard---> Shortcuts---> Display---> Changed those values to F5 and F6, since they were free for me. And they were able to change the brightness for me. Went to test them, and I was just given that error chim and nothing on the display changed.
So I went on down the list... Accessibility---> checked Contrast and changed those to F5 and F6. Ahhh, now I can change that. Now I know that I can use the F5 and F6 for something.
I know that you are talking about brightness, but double check the Contrast settings to see if you were mistaking the two. After years of setting my TV with Video Essentials, I still get the two mixed up from time to time.

Mac Mini lagging after upgrading to Mavericks

Upgraded Mac mini to Mavericks. System before was running great with no lag time and fast with the internet along with different applications, email, uploading photos, no problem. After upgrading to Mavericks noticed lag times in logging into different applications, browsers, email and definitely uploading photos. Did a speed check on four different sites and all were over the 15mps up and 1 down with my internet provider. Before I had 4 up and 1 down with my internet provider before provider upgraded everyone to the 15 up and 1 down, it was fast so no problems before. Any suggestions before I drive to Des Moines for a Genius bar appointment? Thanks much appreciated.

Internet browsing ludicrously slow after upgrading to Mavericks

Hi All,
I wonder if someone could possibly offer some suggestions please.
Everything was fine and running sweetly on ML.
After upgrading to Mavericks, Internet browsing has become ridiculously slow.
Safari, Chrome and Firefox all exhibit the same problems.
Spotlight isn't indexing, and nothing else is 'hogging' any resources.
There are no issues with my routher or modem ad my WindozePC works just fine.
I have seen posts by people recommending clearing the Cache and Preferences files.
Within these folders though, are settings I don't want to lose. (reg info for software etc.)
Due to geographical restrictions, a trip to the Genuis Bar isn't an option.
Could someone please offer some advice?
Many thanks in advance.

Hold down the Option key while emptying the Trash.
As for your Mac running slower... make sure there's enough free disk space.
Click your Apple menu icon top left in your screen. From the drop down menu click About This Mac > More Info > Storage
Make sure there's at least 15% free disk space.

My macbook pro is running really slow after upgrade to Mavericks

my macbook pro is running really slow after upgrading to Mavericks....any ideas?

OS X Mavericks: If your Mac runs slowly
The above link is not very useful, so if it doesn't help read on.
There are many potential reasons that a Mac may be running slower than expected, but more information is required to begin troubleshooting, much more.
Back up your documents and everything else important to you before proceeding. It is premature to conclude your hard disk is failing, but the symptoms you describe may presage an impending disk failure, and you should have backups anyway.
To help determine the possible causes of this behaviour read the following. None of what follows is intended to fix anything, but it will provide the additional information required to advance troubleshooting:
Boot OS X Recovery by holding ⌘ and r (two fingers) while you start your Mac. At the Mac OS X Utilities screen, select Disk Utility. Select your startup volume (usually named "Macintosh HD") and click the Repair Disk button. Describe any errors it reports in red.
When it finishes restart your Mac and test again for operation. If it's still not behaving as you expect it should, please post the results of EtreCheck in accordance with the following instructions:
Apple Support Communities contributor etresoft wrote a very useful app to quickly gather certain system information that may help point to a cause of this problem. Go to his website, download and run EtreCheck:
http://www.etresoft.com/etrecheck
Etrecheck will be in your Downloads folder. Open it from there. You may see the following dialog box:
Click Open - etresoft contributes to this forum frequently and can be considered a trustworthy developer.
It will take a moment to run as it collects its data.
Copy and paste its output in a reply.
Do not be concerned about anything that says "Problem" or “failed” or anything else that may appear in red.
EtreCheck was designed to remove any personal information (such as your computer's name and serial numbers) but if you see anything that looks like an email address or any other personal information that should not be divulged to others, please delete or obscure that information when you post the reply.
When you are finished with EtreCheck, quit the program. It occupies very little space, and you can keep it or drag it to the Trash as you wish.
After completing the above please determine if the problems also occur in "Safe Mode":
Safe Mode or "Safe Boot" is a troubleshooting mode that bypasses all third party system extensions and loads only required system components. Read about it: Starting up in Safe Mode
You must disable FileVault before you can start your Mac in Safe Mode.
Starting your Mac in Safe Mode will take longer than usual, graphics will not render smoothly, audio is disabled on some Macs, and some programs (iTunes for example) may not work at all.
Merely starting your Mac in Safe Mode is not intended to resolve the problem, it's to observe its performance without certain additional components.
To end Safe Mode restart your Mac normally. Shutdown will take longer as well.
System performance problems for reasons that cannot be isolated to any other cause justify an SMC reset. Be sure to read the procedure carefully and follow all the steps exactly as written, even if they seem inapplicable or trivial.

Hold down the option key and select Go ▹ Library from the Finder menu bar. From the Library folder, delete the following items, if they exist:
          Containers/com.apple.Preview
          Preferences/com.apple.Preview.LSSharedFileList.plist
          Preferences/com.apple.Preview.SandboxedPersistentURLs.LSSharedFileList.plist

After upgrading to Maverick, I can no longer access iTunes Store.

Hi,
After upgrading to Maverick, I can no longer access to iTunes stores. The layout for Mac AppStore also doesn't display properly. Perhaps the most annoying part is when I need to access secure website (even google.com), where I need to authorize the certificate. My current connection is behind proxy, but have no issues on all this issues before upgrading to Maverick. Please assist.

Hello segordon21,
Thanks for using Apple Support Communities.
To move voice memos to your computer please follow the steps from the iOS 8 Help below.
Move recordings to your computer
You can sync voice memos with the iTunes library on your computer, then listen to them on your computer or sync them with another iPhone or iPod touch.
When you delete a synced voice memo from iTunes, it stays on the device where it was recorded, but is deleted from any other iPhone or iPod touch you synced. If you delete a synced voice memo on iPhone, it’s copied back to iPhone the next time you sync with iTunes, but you can’t sync that copy back to iTunes a second time.
Sync voice memos with iTunes. Connect iPhone to your computer, then in iTunes select iPhone. Select Music at the top of the screen (between Apps and Movies), select Sync Music, select “Include voice memos,” and click Apply.
Voice memos synced from iPhone to your computer appear in the Music list and in the Voice Memos playlist in iTunes. Voice memos synced from your computer appear in the Voice Memos app on iPhone, but not in the Music app.
Move recordings to your computer
Take care,
Alex H.

Windows Fails to Load After Upgrade to Mavericks

Related topic:

I'm a little late to this party, but hoping to find some help. I can see my WindowsXP Pro partition on the desktop, but after upgrading to Mavericks it won't fully start up. I'll get the usual screens, then the XP loading screen with the blue loading animation. After about 5 passes of the blue thing, it will hesitate and flash a blue screen so fast, that it took me several attempts to snap a photo so I could read it. "Unmountable_Boot_Volume" is the error. It then says to follow these steps... but cuts off and reboots.
One thing of note is that Parallels 10 uses the same XP virtual machine and boots just fine, so I figure XP can't be all that messed up. Maybe a driver issue, not sure. Does Mavericks not support XP? I'm open to Windows 7, but I'd like to backup some stuff first if possible. Maybe I can do that through Parallels?
Below are some details about my setup:

Upgraded from 10.6.8, but I tried unsuccessfully to upgrade to Lion first. That went all screwy but was able to go all the way to Mavericks instead. Proobably where things got messed up. I don't remember exactly how I fixed it. I didn't think I could go that current with this hardware.
