New iMac late 2012 judders when scrolling up and down

new iMac 27" i7 quad core late 2012 the web pages judders when scrolling up and down

Hi,
The judder was up and down when scrolling, I think that I have resolved the issue regarding the juddering, I looked at what software I had recently installed, first I removed the software that I think was causing the juddering problem! it was a bit better but did not remove it completely, AutoCAD 2013 was the software that seems to be the culprit which must have messed up the graphics diver someway.
In the end I erased the hard drive and set the OS back to it's factory settings, which has resolved this juddering issue.
NB: when restoring the OS I lost ilife.

My 2008 imac keeps freezing up when idle

My imac 10.5.8 hs started freezing up after being idel for a short time. What is causing this? I've done the routine checks of hardrive test, checking memory, etc.

Hi Blane756,
Thanks for using Apple Support Communities. This article has steps for a different issue, a gray screen at startup, that I think would still be worth trying for your freezing issues:

Yosemite has ruined performance of my 3-year-old iMac with freezes, application shutdowns and more. What can I do?

Since installing Yosemite my iMac frequently freezes, particularly when I have multiple windows open/apps running. I've never had this problem before. All my apps are installed on a solid-state drive and all documents, etc. on a separate drive, so I'm accustomed to fast performance. Most problems seem to occur with Microsoft Office (Word and Entourage) and Safari, but that's what I use most heavily, so no surprise. I have always been able to keep a lot of apps/windows open on desktop without performance problems, until now. Yosemite is leaving me stranded. (I upgraded to Yosemite because a couple of the newest apps I use on my two Macs and iPhone require Yosemite.) Any advice?

When you have the problem, note the exact time: hour, minute, second.

Since I upgraded to maverick, My iMac got sluggish specially when it wakes up ; anyone got a solution?

Since I upgraded to maverick, My iMac got sluggish specially when it wakes up and for instance, opening Iphoto. I suppose the new approach to more energy saving features could have something to do with this, but nevertheless, i wish I could choose to make it faster. Any clues?

Imac pointer freezes when installing OSX,

Imac intel 2010, mac freezes when Scrolling (Safari, Adobe PDFreader. called support, they suggested a hardwaretest, done that result OK.
Than they suggest to clean HD and to instal OSX.6 again.
Deleted HD. Try to do new installiation OSX6 from dvd, Imac freezes again during installation for several times at ca. 32 minutes to go.
What can i do?

You can attempt to reset the PRAM in the machine, but it looks as though there's a hardware problem. It's actually kind of difficult to determine if it's the graphics hardware or the mainboard, but neither are really servicable. You'll want to take it to get serviced.

Late-2009 iMac elusive freezing when uploading video

Hey All,
So I am currently experiencing a freezing problem when I try to upload youTube videos through firefox and/or safari after... a checkered past. Hopefully this isn't TMI, just being thurough to save your valuable effort.
iMac Details:
21.5-inch, Late 2009
3.06 GHz Intel Core 2 Duo
4 GB 1067 MHZ DDR3
ATI Radeon HD 4670 256 MB
OS X 10.8.5 (12F45)
I am using bootCamp with windows 7
     -fyi i did have w7 virtual RAM manually defined (properly or so I thought) and have since reverted to cpu defined vram.
Funny part is when I was exporting a video from iMovie while simultaniously mixing tracks on virtualDJ while playing a youtube video, everything was fine. Now the history...
1. Trouble started when I was getting the 'click of death' and the 'beach ball of death' seemingly at random while running various apps one at a time.
     -I reset my PRAM
     -I was and am still totally unable to run AHT (superdrive is dead and all key comands do nothing)
     -I verified disk permissions (there were a lot of errors so I repaired them)
     -I verified the disk (it passed), I repaired the disk even though it didn't need it.
     -I downloaded, installed and ran MemTest. (passed 100%)
     -I determined that I might have a kernal extension problem so I deleted Virtual Box and that seemed to calm things down... for awhile.
2. So there was peace in the galaxy for a couple months until after running in my windows partition I tried multiple times and could not boot into my OS X partition.
     -I again reset PRAM
     -I again verified and repaired disk permissions (all went fine, tho agian there were many permission errors)
     -I again verified and repaired the disk (even though it passed)
     -I safe booted, it worked
     -I booted into OS X, it worked.
3. Now, I can restart OS X whenever I want but hard freezing (finder is not responding and refuses to relaunch) still occures when uploading video to youTube having tried multiple browsers.
     -Before when it froze Activity Monitor showed no disk activity, and plenty of realMemory was available.
     -I haven't actaully gotten a read form Activity Monitor when trying to upload. I will tho.
     -I have been unable to find any 'memory leaks' tho I may not understand how to track this
     -My bootcamp partion is totally fine and I've since allowed the CPU to define vram
     -Memtest just now passed all tests.
     -I have had to do hard restart several times while trying different internet browsers.
     -My OS X partition has 344.22 GB free of 1.35 TB.
     -I have no external hardware plugged in, only a USB keyboard and mouse.
So, a few questions...
     1. Did my manual addition of Virtual RAM on my bootcamp partition mess up my ram? if so why does it still test okay?
     2. Do I have to run memtest as the root user to get a real read on my ram? I haven't done this, yet.
     3. Why do I still get freezes while uploading video even tho when I try to max out my memory usage everything runs fine, no freezing?
     4. Is my hardrive messed even tho it passes checks when I'm booted to an external recovery drive?
     5. Is Apple trying to tell me they want more of the money I don't have anymore because I bought this thing 5 years ago?
Ya'll are heros for even trying. You knew that. I'm just reminding you.

So, I've been attempting to solve the issue by using diskUtility to erase free space on my mac and bootcamp partitions to identify bad drive sectors. Unfortunately erasesing free space did not work after defrag on the bootcamp partition. It simply crashed.
Intitally on the OS X partition I did successfully erase free space and that improved all problems for about 3 days. Then freezes became random and increased in regularity. So I moved about 500GB of data to an external drive (the important stuff) and tried to erase free space again to make it identify bad sectors. So I've tried both booting into my external and recovery drive and having the utility erase free space. Both atempts failed when the utility simply gave up after 2hrs and would no longer recognize the drive. I'm booted into my mac partition right now and am gettimg more random freezing with 2/3 of the drive free.
I'm resigned to claiming warranty and replacing the drive after upgrading it about 2yrs ago but can't find any real info on what my model and serial number are. All info that I've found does not seem to direct me to the correct information as I've tried entering it into Seagate's website and it will not accept my input. Any advice on claiming on my Seagate warranty and possibly what the model and serial number should look like? I can't seem to find the right numbers.

I downloaded Mavericks and now when I google a topic and select I then cannot scroll back to the original google page?

I downloaded Mavericks and now when I google a topic and select one, I then cannot scroll back to the original google page if I wish to try a different answer?

Sorry, I'm not very good at describing the problem. If I had multiple browser pages open, prior to downloading Maverick I could swipe the mouse to go back or forward as required. Now if I google a subject and the page comes up with all the choices and I pick one, I now cannot swipe back to the first page , I have to re-open google each time, type in my seach and start from scratch.

When scrolling vertically there is an horizontal line which causes distorsion of the screen. I do not have noticed such concern on my iMac or on my macbook. What happen with the macpro ?

Magic Mouse sometimes choppy when scrolling on new iMac

I'm posting this here rather than the BT forum because my intuition tells me that this is iMac/Safari/Snow Leopard related as it sometimes happens sometimes not. When scrolling works optimally (75 %+ of the time) I love the mouses simple aesthetic and fluidity. I'm also intuiting that as the various iMac/MM complaints are resolved (10.6.2?) the 75% will turn into 99 %

HI Dennis,
Try deleting this file.
com.apple.driver.AppleHIDMouse.plist
~/Library/Preferences.
Move that file to the Trash... see if that makes a difference.
Also, sometimes deleting the mouse from the System Preferrences/Bluetooth devices window then re-"pairing" the mouse helps.
You can report issues here. http://www.apple.com/feedback/macosx.html

Screen ripple effect when scrolling after installing Mavericks?

Since downloading Mavericks some three weeks ago, my screen ripples (wave effect) when scrolling.
Dominic kindly responded a short time ago with the suggestion it could be Autocad update related.
All traces of Autocad wiped from my machine but still experiencing this ripple effect when scrolling.
Beginning to wish I had not updated to Mavericks.
Help!!!

Mine too have this on my new MBP ( September 2009).
It's more evident in Safari, but show also in finder while scrolling. It is not related to font antialiasing because enlarging page text in Safari (cmd +) the blurry effect is still there.
I'm very disappointed of lcd screen quality, too much fatigue to eyes.
Could be considered a screen hardware defect?

How do I get an iMac to automatically restart when screen freezes and computer has to be restarted at plug

Occasionally the screen on the Imac will freeze and the compute has to be restarted at the plug, but when the plug is switched back on the computer only switches back on fully with the screen coming on if you switch a button around the back of the computer, but I remember when using an iMac G4 it would come on automatically when th computer was switched on at the plug. Is there any setting or any software that will automatically restart the computer when the computer is off and I restart it at the plug?

You cannot, what you need to do is find out why your computer is freezing. Perhaps you can shed some light by posting an EtreCheck report and we can see how your system is configured and look for any obvious red flags. You can get EtreCheck by clicking http://www.etresoft.com/etrecheck

30EA3: Monitor sessions grid freezes when scrolling lo last session

Hi,
I've found an issue with the Monitor Sessions grid.
Steps to reproduce the problem (scenario I have tested an reproduced the issue)
1. Open monitor sessions window
2. Order the grid by "OS User" column (In this scenario, my "OS user" is the last one alphabetically)
3. Scroll down in the grid, until reach the last record (as mentioned above, the last session is the same session that is monitoring since my user is the last one alphabetically)
Then SQL Developer freezes, processor time and memory start to increase; and also, seems that SQL Developer window is trying to get the focus, so it doesnt let me navigate freely to other applications, is even difficult to open task manager to kill the process since SQL developer window in the background keeps getting the focus of mouse and keyboard.
Thanks and regards
Ramiro Teran

Hi Raghu,
1. As I mentioned, the scenario I tested was the "Monitor Sessions" grid, at first I only tested scrolling down to the last record, in the master grid using the mouse wheel, but now I have also tried crtl+end, and it also happens
2. 184 records in parent grid (Sessions)
3. The child grid is the "Active SQL" tab (first tab) of the detail of the session.
4. Yes, there was a cell in master selected, but when scrolling down and reaching the bottom (or doing ctrl+end), then the last cell is selected automatically, and SQLDeveloper freezes.
As mentioned in my first post, the SQLDeveloper not only freezes, but doesn't let you navigate to other windows (every couple of seconds SQLDeveloper gets focus on its window, even though is frozen)
I have took an screenshot showing the issue, even though, maybe you can't appreciate the issue on an image, since the image only shows the last record of the monitor sessions grid selected, (at that time SQL developer is hanged, and doens't respond to clics or keyboard comands). Also it shows the Task Manager showing increased memory and CPU ussage from the SQL Developer process. If you're interested in this screenshot, let me know where/how to upload it
Thanks and Regards
Ramiro
