My new imac is barely 3 weeks old. I just installed the latest update to the OS - 10.8.3. Ever since when i use the magic mouse for scrolling up or down, the screen shakes and jaggers. Its really annoying. Apple telephone support was of no use and just asked me to take my computer to a service center. Any suggestions on how to fix this? Pls help.
iMac, OS X Mountain Lion (10.8.3)
Hello Mannish,
Can you describe it a bit more? Is it shaking side to side or what?
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
Hi,
It's basically the part of the screen that I scroll which shakes up and down in a vibrating motion, giving a kind of blur instead of the smooth scrolling motion that we are used to. It's also happening in apps like google earth. It feels as if the display driver is not able to handle the scrolling motion. The apple support guy did guide me through the repair procedure like you suggested but it did not help. He said it must be a hardware issue. But since it happened right after the last update I'm thinking it has to be software related. It's quite painful to lug such a big machine all the way to the service center.
hi,
i have the exact same problem when your scrolling,
and also if you use the notification bar on the right side of the screen when it comes out the hole screen shakes a lot same thing when it goes back, and it leaves a little white bar on the top bar in the upper right corner of the screen next to the notification symbols and the magnifying glass.
it is really annoying.
does anybody know how to solve it ?
I have the same problem, but only with Magic Trackpad or Magic Mouse. Scrolling normal with USB (wired or wirelss) mouse.
Help.....
Try changing the scrolling speed: System Preferences / Mouse.
Sorry, I don't have a setting for scrolling speed. Only for mouse pointer speed. Same in trackpad pref pane
I'm running 10.8.4, maybe that has changed in update from .3?
Anyway to acces scrollingspeed/smoothing outside trackpad or mouse pref pane (terminal)?
OS 10.8.4
That's only when no Magic Mouse is connected.
With Magic Mouse:
Found scrolling speed settings in Accessability (translation OK? I have Dutch version OS X...), but changing anything there doesn't help.
I've got the same problem as MartijnFromNLD described.
Also, I'm not able to find where to change scrolling speed.
The question is, if the changing of the scrolling speed will help with that problem.
Scrollspeed can be changed as follows:
But it doesn't help with our problem....
As you said.
I've tired to change the scroll speed but it didn't help with scrolling shakes...
Try a restart.
Do a backup, using either Time Machine or a cloning program, to ensure files/data can be recovered. Two backups are better than one.
Try setting up another admin user account to see if the same problem continues. If Back-to-My Mac is selected in System Preferences, the Guest account will not work. The intent is to see if it is specific to one account or a system wide problem. This account can be deleted later.
Restarts: no effect!
Other admin user account: no effect!
I've noticed that the problem with scrolling shakes only apears in Mail programm.
On my iMac it happens in Safari, Mail, when switching between 2 desktops. Any app when scrolling through screens with both pictures and text. Only text not so bad, only pictures also not so bad.
Have you tried with USB mouse? In my case that solves it, but that's no real sollution, because I want to use my Magic Trackpad with all the gestures!
I am planning to reinstall OS X. First clean install and testing with Magic Mouse, Magic Trackpad and USB mouse (if necessary). If problem still there: I will return iMac to shop and they can fix it (hopefully). If problem gone after reinstall: Then reinstall and restoring backup from TimeMachine. If problem back after restore, then I need to search wich app is the problem.
But for reinstall I need to plan time, because I need my iMac often!
