New IMac mouse not working properly

Bought a new IMac. How do you solve the problem of the mouse pointer jumping all around the screen? It seems like the cable is causing the pointer to be uncontrollable at times.

Go to your System Preferences and then select the Mouse and when it opens it will give you some choices.
Here is how mine is set up and I have never ever had an issue.
Hopefullythis can help you sort out your problem
Cheers
Don

new tab is not working properly.ie.,i can not open new tabs in firefox.

Uninstall the Ask toolbar and it should work again. There is a compatibility issue with the Ask toolbar and Firefox that prevents new tabs from being opened.

My mail on iMac is not working properly. Click on email, it hangs, showing previous email. Takes forever to load. "No message selected" showing in a blank screen

My mail is not working properly: when I click on an email it hangs, frequently showing the previous email, often for up to a minute. Or it shows "loading" and just sits there showing nothing. OR there is a blank screen saying "no message selected". It's slow to load, and I'm not happy. Recently switched from Windows PC, not impressed so far. Very frustrating.
Any suggestions would be gratefully received. (I upgraded to Mountain LIon, and don't think I had problems before I did so, though I hadn't had the computer for long.)

Hi Sarah,
Open Console in Utilities & see if there are any clues or repeating messages when this happens.

20" iMac, display not working properly, otherwise OK

I have a 20" imac with 10.4.11 loaded, Have had it for about 2 years, no problems at all except occasional wake-from-sleep issue. All of a sudden, the display has quit working properly. The computer sounds like it boots fine, but the display only shows a very deep blue (not black)and the light ind the lower right corner is "on".
I tried holding a flashlight up to the front as some have suggested, and I do not see see anything at all. This would seem to rule out backlighting or screen brightness issues. I have also reset the PSU and the P-ram, also to no effect. Tried booting from the 10.4 disk, also to no effect.
My teenagers won't admit having any problems, but one of them did admit to turning off the system several times using the power button in an attempt to reset AirPort. Any thoughts? the only other easy thing I can think of is the battery, could that be causing this much trouble? do the display cables ever detatch from the MB or anything like that? any ideas greatly appreciated.
Thanks, Eric

Hey Eric,
This is from the Service Source:
"Screen is dark, fan is running and the hard drive is spinning. You may hear the startup
chime as well.
1. Reset parameter RAM. Press Command-Option-P-R during startup before “Welcome to Macintosh”
appears.
2. The system software could be damaged. Start up from the system CD that came with the computer.
3. Remove the user access panel on the bottom of the computer. With the unit powered on, check if a red
LED is visible in the access door. If the red LED is on, power is on. If you don’t see the LED glowing
red, follow the steps under the symptom “No Power”.
4. Disconnect the A/C power cord. Place the unit in the service stand and remove the user access plate.
Press the PMU reset button on the logic board. Refer to “Resetting the PMU on the Logic Board”
mentioned earlier in this chapter.
5. Check for external video. Connect an external monitor to the mini-VGA port. If you don’t have external
video, replace the main logic board. If you do have external video, go on to the next step.
6. Open the bottom housing and verify that all the cables are securely attached. Pay special attention to
the video cable (located near the modem). If the cables are securely attached, go on to the next step.
Warning: Whenever the bottom housing is opened for service, you must do two things:
• You must clean the original thermal film from the surfaces joining the thermal interface layer and
reapply thermal paste to the thermal pipe.
• The bottom housing has four torx screws that must be tightened to at least 17 in.-lbs. If you do not
have a torque driver, you will have to make sure these screws are tightened by hand FIRMLY, BUT
NOT FORCIBLY. Or, purchase the service tool (076-0899) in order to ensure the thermal pipe is
firmly mated with the top base. If the bottom housing is not securely attached to the base in this
fashion, the CPU may overheat and become damaged.
7. Check the connection of the video cable to the LCD flat panel display (under black tape).
8. Replace the inverter board.
9. Replace the LCD display. Important: If you are replacing the display, be sure to install the new display
shield and EMI gaskets that come with the new LCD panel. Installation instructions are included with
the new display panel. Additional display shields/gasket kits are also available separately as a kit, part
#076-0958.
10. Replace the neck assembly
11. Replace the logic board.
12. Replace the power supply board."
In my experience the connectors both on the logic board and on the back of the LCD panel have been known to come loose. I also have a neck assembly here that went bad.
If you need more info email me.

Brand new iMac does not work wirelessly

This is a very strange situation and I don't know how much to be concerned about it.
6 weeks ago I bought the first of two brand new iMacs. We have two old G4s both wired into a Netgear wireless router, plus the printer. The first new iMac when switched on, immediately found the Netgear and has worked perfectly, wirelessly, ever since. As it should.
Less than a week ago I bought the second new iMac, which is identical to the first. I put it on the _same desk_ as the Netgear, therefore a distance of only one foot. Straight out of the box, it worked wirelessly to register itself with Apple.
Since then, it has only worked wirelessly very intermittently, and then very slowly indeed. I was wasting far too much time trying to figure out why the wireless did not work, and eventually wired it into the router too.
I was attempting to set up a network with 2 old G4s wired in, and 2 new iMacs wireless. Now I have 3 wired in and one wireless.
Is there something wrong with the second brand new iMac? Or is there some line I should be pursuing with Netgear?
I have written all the IP addresses down in case anyone responding - and I sure hope SOMEONE responds! - thinks that this may be a clue.
Many thanks in advance to all and any replies.

Update: I'm posting this in case it helps others......
I phoned the software support which comes free for 90 days with a brand new iMac.
The bright young man there instantly knew what the problem was, because he'd seen it all before. There's nothing wrong with the iMac and it has nothing to do with IP addresses.
I have to go into the Netgear configuration screen and Enable MAC filtering. This means I'll give the router the hardware addresses of the two iMacs and it will then allow both of them to communicate wirelessly - but no other devices which might be lurking in the vicinity.
Sounds good to me.

New iphone 5 not working properly

Why my iphone not showing the plug icon on battery even it is 100% charge ,lightning icon is not changing .and also the rotation of the screen is not working ..what should i do?its is new just used it for one day.

If it is that new, I'd suggest you take it to your Apple Store so they can assess it and/or show you how to put it thru its paces.

New movies files not working properly

Hello,
I have a new all in one HP pc with Windows 8. I have completed all pc updates and including latest Java. I have downloaded Itunes 12 and imported my old Itunes library from my network drive. My itunes library was created on an XP system and I still have it mapped to my Network Drive as it is 2TB in size.
The library contents are all fine and everything works. My problem is now any new movies m4v, mp4 which I import does not work. Itunes will upload the files, which then appear in the Home Video section. When I try to add artwork, or move file into 'movies' or even play the film Itunes goes into 'Not Responding' and I have to shut it down from from task menu. This issues only occurs with new movies. New music is fine.
I have tried to use alternative compatibility option none of these work.
Does anybody know how I can get my new movie content to work? btw the files are good as I have tried them on another system and they work just fine.
Thanks

anybody have any ideas?

Power button on brand new iMac doesn't work properly?

Hello,
I am having problems with the power button on my brand new iMac which was purchased 2 weeks ago. Some days I press the power button and everything works fine. And then some days, I get no response from the power button. I then just unplug and replug the power cord from the surge protector back in and then the power button works!
I also shut down every night - I don't put the computer to sleep.
Can someone tell me what is going on? I've searched these message boards and see old post from others out there have also dealt with problem.
Any advice or insight would be most helpful! Thanking you in advance.

A couple of things first your machine has a 1 year warranty and is covered by 90 days of complimentary AppleCare. You should contact AppleCare to get the machine fixed.
Next please carefully read your owners manual, below is what Apple specifys,
"If you'll be away from your iMac for less than a few days, put it to sleep. When your iMac is in sleep, its screen is dark. You can quickly wake your iMac and bypass the startup process."
Personally I only let the monitor sleep, my system has been running like this for 4 years and is the most reliable computer I've ever owned.

New 'resume' feature not working properly

Hi All!
As there does not seem to be a manual for Lion, I am hoping someone can answer the following questions for me:
I have assigned various applications to different desktops (spaces). Unfortunately, after a system restart, these are not restored to their assigned desktops, but all open in desktop 1. I think the 'resume' idea is great, but this kind of spoils it for me. Am I just doing something wrong?
Also, Lion does not remember whether an application was closed or open. It will just open any 'active' application to a full window, which is also kind of annoying. So, yes, resume is an interesting feature, but unless Lion remembers the exact state the app was in before restart, it is completely useless.
I am hoping that I am just missing something like a setting or such, and that one of you has already found out how to change it.
Thanks,
Sib.

Great New User works!
I don't have one, so I'm not certain what to look for, but MOST of the User stuff is kept in...
/Users/nnnn/Library/Preferences/
One interesting one that I find is..
Users/nnnn/Library/Preferences/ByHost/com.apple.keyboardtype.0003930b0244.plist
Likely the numbers before .plist will be different on yours, try dragging that, (those), file(s) to the desktop, (we can drag them back later if need be).
Then log out and back in, might have to you Keyboard setup or the Control Panel to setup the KB again.

Bluetooth Mouse not working properly

I have a MAC bluetooth mouse and recently the scroll wheel only works to scroll up, left and right, but not down. I have tried turning off/on the computer, force quitting the Finder, turning off and on again the mouse. Nada...
Any thoughts how to fix this?

This is a common fault with the MM. There are many threads on this. Certainly googling will gives you plenty of results!
The best solution I found from a tip was to remove the batteries or turn it off and then rub the mouse upside down on a clean piece of white paper. Move it in all directions - 360 degrees.
Carefully though so as not to put too much pressure on the buttons.
After a while look at all the dirt on the paper which has been transferred from the ball.
Turn it back on and voila! A fully functioning MM.
Try it! You'll be surprised.

New Macbook charger not working properly on one side

Hello,
I've recently sent my macbook in to get the exterior fixed. Upon its first charge I noticed the light on the Apple 60w Magsafe power Adapter never turned on, (indicating me that it is in fact charging)
This problem only occurs if its charging with the wire facing away from you, not towards you (because you can attach the charger two ways) It works if its charging with the wire facing towards me, but this usually is a very awkward and uncomfortable way to charge my macbook. I have two identical chargers and it does the same for both.
Is there anyway to help this problem? Or does my charger need replacing?
