Erratic behavior.. mouse, keyboard or iMac?

Ok, connected mouse to right usb port on keyboard, mouse acts erratically when you hover over anything clickable, and acts like “hot corners” by zooming out to desktop. And numbers on number pad on keyboard not working.
When connected to the left side of keyboard, mouse works fine but number pad still not working.
When plugged usb port on back of iMac, mouse behaves erratically again.
It acted like this with OS X and I thought upgrading to Mavericks would fix it, but it hasn't.
What's up?

1 Mouse / Keyboard 2 iMacs

I have a 27" iMac for play, and a slightly older 24" iMac next to it for work. Can I use my wireless keyboard and mouse to control both computers?

Yes, but not at the same time. The keyboard and mouse can be paired with both machines but only connected to one at a time. Therefore it must be disconnected from one machine before connecting to the other. If the machines are sitting next to each other, the only practical way is to turn off or put to sleep one machine and then start the other.
If you want to use the machines at the same time, the answer is no.

Erratic behavior from keyboard or CPU?

When I booted up my G4 yesterday and tried to log in, it acted like it wasn't going to enter the password I was typing. Then, suddenly, it began typing in a string of keystrokes and everytime I tried to click on the password field to retype it kept repeating the string.
I shut down and rebooted, zapping the PRAM and it allowed me to login but while using my email program I pressed backspace and suddenly it was deleting everything I'd typed. I clicked off the message (and unfortunately in my mailbox) and it began deleting all my emails!
The keys on my keyboard felt a little 'sticky' or slow to move and someone else had recently used it so I thought maybe something had spilled on/in it (I can even see some drops of liquid under the clear plastic casing) so I brought the keyboard into work to test here. I have been able to type this entire post without incident so now I'm concerned that my CPU may be wigging out.
I haven't been able to eject the CD tray from the keyboard, but may try the old paperclip trick so I can run DiskUtility.
Any other suggestions? BIG THANKS in advance!

Erratic magic mouse behavior

Will anybody ever be able to decipher what the specific causes are for the erratic behavior of Apple's Magic Mouse? Personally I think it boils down to the Bluetooth Signal itself that can cause a lot of this erratic behavior, like in sudden sluggishness of movement. I see this behavior comes and goes as if some invisible force has suddenly intervened. My best guard against erratic behavior is to have the computer as close to the mouse as possible, even a foot or two. The further out the computer gets the more erratic behavior is likely, but like I said, even then it "comes and goes." Do you think it is the Bluetooth signal itself, because sometimes when it's become erratic I move the computer around, even which way it faces in relation to the mouse and I can suddenly "lock on" and the mouse returns to normal, only to have it start acting up again in a few hours or later on in the day or week or whatever. That's why I say the signal itself is suspect because I can effect the behavior by moving the computer around. Maybe the signal is effected by other components in the room like my TV or Audio Equipment or WIFI signals or remote controls.
I love my Magic Mouse and that is why I have put up with this erratic behavior struggle I'm constantly/periodically having, but I do wish this problem could be eradicated altogether and i could just use the mouse like it was intended. Incidentally, this is a brand new mouse I'm currently using that is at issue. All my other Magic Mouse have also done this exact same behavior.

Hi, thanks for the reply. Yes I'm running Yosemite 10.10.3. I'm certain much of what you posted is definitely a likelihood for some of the issues. I have a lot of electronic equipment in this house, and yes, smart tv's connected to WIFI as well as other computers throughout the house. Apple of course does not mention any of this as possible issues as far as I know, the public, like myself, just assumes all will be wonderful. I know there are more like me out there if I'm having these consistent problems with all the Magic Mouses' I've owned. It really is attacking it from the SIGNAL side of things because I think that is the only issue that's going on. If it were addressed more, maybe even scientifically, maybe we could say, "well don't put it here, this can cause problems, and that TV, keep such and such a distance." Those are the types of guidelines that would be so helpful. But from what I'm seeing none of that is addressed at all (or for the most part). Anyway, I really want the wireless mouse world (specifically the Magic Mouse) to thrive. Every time I hook up a wired mouse I really feel the step back I'm taking and it's too painful! I've even went to the point, and I'll do it again if need be, of having my computer (Mac Mini) 2 inches from the Magic Mouse, that's when it operated at its very best. My only problem with that is it's somewhat impracticable, and I really don't think I should have to do that to have it work consistently. Anywho, my two cents worth.

HT201343 Controlling the iMac desktop from a different room using mirroring (mouse/keyboard)?

How are you meant to control the imac desktop from a different room using mirroring (mouse/keyboard)? Is there an app for that? Or a solution?

Tried the trackpad out in the lounge and it worked, it's a little less responsive, but a far cry better than using McTivia with usb bluetooth mouse and/or keyboard. I guess the airplay mirroring is at the stage of an add on gimmick. Perhaps in the future AppleTV versions will come with bluetooth support to allow for serious use of the mirroring, especially with gaming. Thanks people!

Wireless mouse and keyboard for iMac G4?

Got an old iMac G4 (OS X 10.4.11) but would like a new keyboard and mouse and wondered if anyone knew of any that were compatible with my Mac? If you do I'd appreciate info on where I could buy, thanks.
*Just to add I've just bought a 'Newertech 802.11g/b Wireless USB 2.0 Stick Airport' so I can now connect to my new Sky Hub and have wireless internet on my Mac. Not sure if this helps regarding my above query?

i use the original apple wireless keyboard and mouse with my imac g4. no longer being sold new but you can pick them up on e-bay. unlike the new ones it has a number pad.

Mouse & keyboard acting erratic

My new G5 2.5GHz's mouse and keyboard are acting up (running 10.4.11.) The mouse is slow and erratic and the keyboard misses some strokes as you type along. I tried changing mouse and keyboard, USB ports, zapping PRAM, trashing universalaccess preference and still this keeps on happening. It stops for about a minute after I zap the PRAM and then starts again. Any idea?

Hello Rosalind3000,
Thank you for contacting Apple Support Communities. You can use the following article to troubleshoot your trackpad issues:

Wireless mouse/keyboard intermittent dis-connects

In the last three days, I have looked at over 20 different posts regarding wireless mouse/keyboard disconnect problems. Thew fixes ranged all over the board and NONE fixed it. And, none of these problems matched mine exactly, except for one other. I too, have two iMacs and this problem has over the last few days gotten increasingly worse and irritating. Regardless of what you're doing, whether it is actual productive work, or playing a stupid game on your computer, when your mouse quits responding, and the graphic flashed on the screen "MOUSE DISCONNECTED", it irritates.
I think a senior apple tech finally pin-pointed the problem, at least for my two systems. It has nothing at all to do with Bluetooth or Wireless networking. I tried ALL of those fixes including resetting the SMC. None fixed it.
Here is what the tech had me do. Under System Preferences > Users & Groups > My Login, I then clicked on "Login items. I was astounded to see a list that exceeded the size of the window of "startup" programs that have been installed from iTunes Helper, to Dropbox to blah, blah, blah. You name it. He had me remove ALL of them except iTunes Helper. one item "Connect service (all users) could not be removed. However, as we later discussed, the specific item the I believe to be the culprit was "Bittorrent". I've forgotten what I downloaded that used that as the download agent, but in the future, I shall NEVER AGAIN use it for ANY reason. I also removed from the applications area, some non-used programs (that probably weren't the problem, but...), emptied the trash, re-booted and have not had the problem since. I want to stress here, that if your problem is actually Bluetooth or Wireless network related, this will not fix it. However, my mouse had gotten really molassesy in that when I would try to quickly move from one spot to another on the screen, it took some time to catch up, as if something else had control. That's what I think Bittorrent or someone trying to share one of my files was causing. I don't share my files. Period. I didn't realize that it could be subverted to that use of I wouldn't have ever used it in the first place.
Anyway, neither one of my iMacs has exhibited ANY of the former symptoms since clearing that list on each system. Turns out, my second iMac also had Bittorrent in the list. That's about the only thing the two have in common besides Yosemite 10.10.3. Maybe this will help, maybe it won't. I sure hope it does. Forums like this one are extremely helpful to me.

I had the same problem... didn't find anything useful in the forums. Just on a whim, I went to the
Control Panel | Device Manager | Universal Serial Bus Controllers
For each "Hub", right click and select "properties"
On each properties page, select "Power Management" tab
On each power management tab "uncheck" the "Allow the computer to turn off..."
I did this for the Generic USB Hubs, the USB Root Hubs, and the Reneasas...Hub. After that was completed, all USB ports started working immediately. So far, they are staying working but it has only been an hour or so. Will report back if this doesn't stick. Also, there may be a more elegant solution... but this works for now.

Connect wireless keyboard to imac

How do I get my wireless keyboard to connect to my iMac? Both keyboard and mouse work fine with my MacBook Pro, but only the mouse is working with the IMAC?

Is the iMac a model built before the year 2006?
...Does your iMac run vintage Mac OS 9.2, pre-OS X?
{If not, you posted a question in a vintage PPC non-intel
discussion area that covers older architecture Macintosh
which cannot run an OS X later than Leopard 10.5.8.}
•Bluetooth - Apple Support:
http://www.apple.com/support/bluetooth/
You'd have to pair the BT keyboard with iMac; they
can only be paired to one device/computer at a time.
Hopefully any additional answers will be found
in the Bluetooth Support site linked above.
Good luck

Extremely slow navigation in full screen mode and other erratic behavior

Hi,
Is it me or every new release of PSE feels heavier and more bloated than the previous?
I have PSE9 running on a dual core, one year old dell PC with W7 with 4GB of RAM. I have the maximum amount of recommended memory alloted to the program (set in preferences).
Ever since I upgraded, moving forward (or backward) to the next pic (via pagedown, or up) through the filmstrip in fullscreen mode has become very, very sluggish. Sometimes it just will not move to the next image even when thi image is in the same directory as the previous one.
Is this sluggish navigation normal? Or is there something that I can do to improve performance??
I look at images in fullscreen mode to decide which ones to edit and which ones to delete so I use this feature a lot. Another example of sluggish-- or in this case erratic-- behavior happens when looking at an image in full screen and then I decide to edit the image. I load the image to the edito by clicking the editor icon on the left options pane. Even if the editor is already open, sometimes it brings the editor to the ferground with the image ready to be edited and sometimes it does not; I have to cycle with alt-tab to make the editor active. Why this erratic behavior? Then, after saving an image and selecting the close button, you are supposed to be returned to the organizer... well this happens sometimes, other times I have to manually swithc using alt-tab.
Please help, this is very annoying.

I don't understand whether you have a Referenced-Masters Library or a Managed-Masters Library. Drives slow as they fill and with a Managed-Masters Library sooner or later the internal drive will become overfilled. I recommend a Referenced-Masters Library with Masters on an external drive and the Aperture Library on the internal drive.
iMacs, laptops and Minis are by definition limiting to heavy Aperture usage, so work carefully to optimize setup and workflow.
First is to max the RAM and make sure the hard drive stays less than 70% full. Restart the iMac prior to a major Aperture session and only have Aperture open. You should also investigate to see if a substantially more powerful video card is available at reasonable price.
Set Preview size to be exactly screen size and build Previews manually when the box is otherwise not being aggressively used.

USB Mouse, Keyboard not recognized in Windows

Hello,
I have just installed Windows 7 Home Premium on my late 2012 iMac, the installation seems to have gone well except that after running the Bootcamp setup program Windows restarted and now does not recognize any mouse/keyboard - USB mouse and keyboeard as well as Magic Trackpad/Bluetooth keyboard are unresponsive. They worked before the restart, and also work in Safe mode.
Has anyone had/fixed this issue, or can direct me to instructions to help? I've looked over the forum and not found same issue. I'm assuming any fix would have to work in Safe mode as I can't do anything in Normal mode!
USB port issue?
I'm also assuming I will have to separately fix the Trackpad/Apple Keyboard issue, but first just want to get basic USB devices working.
Thanks!

Good News: I got it working OK. Not sure exactly what fixed it, but will list what was done differently in case it helps someone else.
1. Did a clean install from the Windows 7 Pro x64 disk I had purchased. The first time I had used an ISO image downloaded from the Internet (not MS site) to create the thumb drive installer, per Bootcamp 4 instructions.
2. Updated the Windows install using MS Update. I had to install some drivers I found on the Bootcamp disk I made the previous time. Those drivers were anything relative to Network and WiFi, so I was able to access the Internet. Before that I couldn't connect.
3. After the above, I repeated the download process that downloades the Windows support software for Bootcamp and made a new CD.
It worked.
I still find the service from Microsoft and even Apple to be an exercise polite but useless finger pointing. Neither organization wanted to help me. As with most tech support groups, the object is to get rid of the problem if possible by blaming someone else. Imagine what might have happened if the Apple tech would have actually conferenced me on a call to Microsoft! Tech support is non-existent for Bootcamp.
Drop a line to [email protected] if you need anything explained about the above. Cheers. -John

Third party mouse/keyboard combos

first post here.
i am going to buy a bluetooth mouse plus keyboard combo.
i am quite interested in logitech mx5000 (http://www.logitech.com/index.cfm/products/details/US/EN,CRID=2158,CONTENTID=107 76&ad=hpb_mx5000)
would this thing work with the integrated imac bluetooth adapter? would all of the F-keys work?
any advice?
marco.

Hi, I'm also interested in that mouse keyboard combo
It says in the specs that the mouse is actually MX1000 for bluetooth.
http://www.logitech.com/index.cfm/products/details/AU/EN,CRID=2135,CONTENTID=904 3
now, that mouse only, in the specs says that it supports mac.
so im guessing just the softwares for the keyboard that might not work, e.g. the features for IM status, etc.

lists the compatible logitech keyboards for mac os
this is another quote from logitech support
"Although it’s possible for you to use a Logitech Bluetooth product on your system, Logitech does not support these devices in any other operating system besides Windows XP and Windows 2000. However, since our devices strictly adhere to the Bluetooth standard, the hardware should operate in other operating systems. Even though the hardware may work, you will not be able to install the software and therefore will not be able to use some features such as secure data transmission and extra function keys or mouse buttons."
so.. its a gamble to buy the set.
or maybe we can buy the apple bluetooth keyboard from apple store and buy MX1000 bluetooth from logitech

NF 980 PS2 Mouse & Keyboard PS2 IC just stopped working.

Hello, My PS2 Mouse & Keyboard intergrated circuit connections just stopped working. My Rig is only 6weeks old & was using Win 7 Ultimate 64bit. Everything was fine untill yesterday. all of a sudden the connections don't work. I tried doing a system restore. rebooted several times, unplugged & reconnected both mouse & Keyboard plugs to the PS2 connections & still not being recognized at boot up. I plugged in a USB Mouse & Keyboard adaptor & is working fine. I'm thinking something happend to the IC chip. Are these Mobo's known for this problem? I don't think I'm going to RMA the Mobo unless something else happens.
Please let me know what you think. Thanks.

Hey Fredrik,
Thank you very much. All I did was shut down & remove the power plug like you suggested & removed the USB Mouse/Keyboard adaptor, & plugged back into the PS2 IC Connections, & it's working great.
Could you explain what happen?
Hi,
Keyboards and mice have electronic circuitry. When you just reboot or reset the machine, voltage still goes to the peripherals like the keyboard and mouse.
It sounds like, for some reason, the keyboard and mouse got into a non-working state, but when you rebooted or reset your machine, since power was still going to the keyboard and mouse, they didn't get reset.
When you unplugged the power, that removed power from everything (well, almost), including the peripherals, so that would've reset the keyboard and mouse.
If you have an external/USB hard drive, you can see this behavior by watching the drive light. When you shutdown your machine, the drive light will stay on, unless you unplug from the wall, or flip the switch on the back of the power supply.

Reconnect Magic Mouse/keyboard after reinstalling Mac OSX

After about a week I finally managed to reinstall Mac OSX Snow Leopard...I took a RAM stick out at random and it worked...good thing there weren't any Genius bar appointments which suited me.
Anyway, now I need to connect a keyboard
I've already got my USB keyboard in it (The same size one as the wireless one...but this one's wired)
I've unplugged it, plugged it back in. I've dug out my wireless keyboard and nothing's happened (Yes, the green light blinks...)
I put my iMac to sleep, I turned it off, it still isn't working...
I could try and find a wired mouse/keyboard somewhere...but I can't believe my wired Apple keyboard isn't working with it ^_^
I'm surprised Apple think this wireless stuff is a good thing...I'm more surprised my wired keyboard won't connect...
It's an iMac 11,2 (I think - Whatever the late 2010 one was) and I'm running Snow Leopard.
Also - When's it safe to put the RAM back in? Or is it actually faulty and I need to get a replacement? How can I check?

Just to clarify, this is what I want/hope to do:
Backup my iMac using Time Machine (Complete)
Format the iMac to factory settings (Complete)
Reinstall Snow Leopard (Incomplete)
Restore some files and folders (Incomplete)
Maybe upgrade to Lion...if I'm in a good mood.
I'm mainly doing this because my hard drive stopped last week, and the hard drive fan sped up. I had to restart, went into safe mode and...I don't actually know what you're supposed to do in safe mode so I restart normally. The next day, I turned my iMac on and it had that bar below the logo as if it was booting in safe mode, the bar appeared to have stopped, so I turned the iMac off, and upon turning it back on, the bar was back, so I decided to leave it and it started fine. The next day, once again, the bar was there so I left it, but once it got to the desktop, Finder wouldn't load, I tried relaunching Finder a few times, then restarted the computer, if I remember correctly, it restarted and Finder wouldn't load again. I tried again, this time it wouldn't boot at all, I Googled it a bit and tried resetting the PRAM, SMC etc., then found that you can read what's happening when it's booting to safe mode, and many errors came up saying that some numbers were incorrect, after a few minutes, it said "Halting CPU" or something, and that's when it turned off. I then booted from the disc, and restored using the Time Machine backup. I wasn't pleased with the backup; some applications failed to load properly. I thought I might as well restore it and just copy a few files across, to save space and speed up the computer.
The many times I tried reinstalling Snow Leopard, it didn't work. I tried many things, and last night I decided to make a disc image or something to a USB stick. I don't think it was an image, because the tutorial I followed which worked didn't require that you create an image. After trying to install from the USB stick, it failed, I then removed a RAM stick, it finally worked! But my keyboard wouldn't connect...that's when I came to creatin this post, and I tried reinstalling again, it failed to reinstall, I tried removing the other RAM stick, still failed.
Last week wasn't the first time my hard drive suddenly stopped, it's happened a few times before, but the hard drive fan hasn't sped up upon the hard drive stopping, and it's also managed to start again and the computer to continue working a few seconds later. Maybe it is about time I take it to Apple...but my warranty's ran out so I'm not sure if they'll help me.

Imprecise, Jumpy, Erratic Bluetooth Mouse with Video

I have been suffering with an erratic Bluetooth mouse problem for almost a year now on my 3.06ghz Imac. Recently, I have noticed others mentioning the same issue with the new Magic Mouse. (See Imac Forum). Therefore, in an attempt to raise the status of this issue I am posting a video in order that Apple Care and other Mac users can see the issue in action.
The jumpiness gets worse when downloading a large file or when copying or moving a large file. I have posted more details in Upper right corner of Youtube page.
http://www.youtube.com/watch?v=OBzisliiVpg

A quick update to the jumpy mouse saga:
After a year of problems with a jumpy mouse (see videos below) *I purchased a Magic Mouse to see if the Magic Mouse would solve the jumpiness issue. It did but the tracking speed was very slow. Therefore, I installed MouseZoom to increase the tracking speed. After installing MouseZoom I started noticing the jumpy mouse problems again.*
_*This finding is very interesting!*_
_*It implies that the faster the mouse movement the more likely one is to see an erratic mouse with the pointer making unrequested jumps around the screen.*_
My hypothesis is that the operating system or processor is not allocating enough resources to the mouse if the tracking speed is set to a high level.
_*The "jumpy mouse" problem seems to be far worse when the hard disk is running - either copying or downloading a large file*_. Some users are reporting that watching a high resolution flash video will also cause the mouse to skip and jump.
I am certain the problem is software related because the same exact mouse works perfectly in Bootcamp 2.1 and Bootcamp 3.0 in Windows XP SP3.
_*Youtube now has two videos showing the problem*._ You can view the videos here:
http://www.youtube.com/watch?v=NxLY3-pH-rs
http://www.youtube.com/watch?v=OBzisliiVpg
If you are suffering from similar problems may I suggest three actions:
* Use the Quicktime X screen recording function to record a video of the problem.
* Post the video to YouTube.
* Contact Apple Care and share your video problem description with them.
* Send a note referencing the video and description to www.apple.com/feedback
Category: Mac OSX Feedback
Feedback Type: Bug Report
Feedback Area: Peripheral/Device Support
I will update this video to let you know if the problem has been solved. I am hopeful that Apple will be able to find the source of the problem and solve it quickly. I really like my Mac and I can hardly wait for the problem to be resolved.
Here is hoping that 10.63 will resolve this issue once and for all!

Erratic behavior.. mouse, keyboard or iMac?
