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?

Mouse cursor acting erratically when install LV6.1 in Win98

Whenever I install LV6.1 in Win98, the mouse cursor acting weird, i.e. it has a busy sign flashing next to it and slow down everything. If I uninstall LV6.1 then it works fine.

Is the cursor acting this way in the LabVIEW environment or just in the Windows environment?
Make sure you are an administrator on the computer and then try reinstalling. Also, if you have another Windows 98 computer around, I would install LabVIEW on there first and see if the same thing happens.

Keyboard acting erratic

My keyboard's gone haywire. If I press Page Up, Expose goes into effect and some random letters get typed. Same thing happens with Caps Lock, except it's the Volume that goes down.

My problem is that erratic keyboard is intermittant. I'll be typing and then next thing I know, the cursor just jumped to another line, text has been highlighted and over-written, background pages jump to the front, etc... Needless to say, just a bit frustrating. Problem seems to exist regardless of application. The only time the keyboard works correctly is when I take it into the Apple Store.... This has been an on-going problem since I bought the computer a little over two years ago.....

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?

Hi PrintTech-
Since your problem is with a G4 computer and this is the Power mac G5 forum, why not try posting in the correct G4 forum. You are sure to receive excellent help there.

My crazy keyboard is acting erratically.

The keyboard, which comes with my new Mac Pro only two months ego, is acting erratically. When I pressing (Left Command + Z) for undo or (Shift + Q) it is not working. If press (Left Command + q) for quit from any applications, it mirrored two monitor (I’m using two display). Interesting thing is “left command” key is working with another combination like (Command + V), (Command + C) etc. I’m sure the problem is in keyboard, because I’ve tried by another keyboard and everything is working fine. Now my question is, how can I fix this keyboard? In Bangladesh there is no warranty for keyboard and mouse (My supplier said).

Reset the SMC and PRAM at least 3x each. For instructions please navigate to:

What OS X are you running and do you have USB or Wireless input devices...?
For wireless devices, take a look at > Troubleshooting wireless mouse and keyboard issues
USB keyboards and mice generally don't have connection issues, but they and there cords do occasionally go bad.

New mac mini intermittent mouse keyboard and track pad

Just got this computer up and running last night. Now the mouse is moving erratically, sometimes it works great and sometimes it stops or moves in another direction. It also effects my trackpad but to a lesser extent. I was using this same keyboard, trackpad and mouse on my old Mini 2011 yesterday and it has worked perfectly at this location for a couple of years. Stumped, looking for ideas.

Try resetting the PRAM and SMC...might help, cannot hurt.

I think it mights be the virus but reading these forums im not so sure.
Laptop with do random zoom in fuctions while in safari.
Its at the point where im ready to take it in to Apple or Geek squad but i know it will cost me an arm and a leg if they solve the issue.
The only time i can normaly use my laptop is if i keep it shut down and keep it off for extended perioud of time
If any one have any sudjestions plz help

First few times I used the Magic Mouse it worked fine. Now I have the same problem I did with old wireless mouse -- pointer goes to middle of screen and then drops to bottom. Keyboard recognizes mouse, and MM will open icons along bottom of screen, but will not function above about 1/2" of bottom of screen. Can't scroll up to close open programs, can't scroll to the left to Finder, etc. Have replaced batteries a couple of times, have rebooted (including powering completly off). No luck. Have an iMac, working in Snow Leopard.

Bluetooth Mouse & Keyboard

Hi,
I new to the world of macs but so far i'm loving it. There only one problem though, my keyboard and mouse are very jittery almost like its short of signal
To my knowledge the apple mouse and keyboard have a 10 meter range no obsticles but mine are only half a meter away from my computer. i have to almost put my mouse on top of my g5 to make it smooth out.
there isn't much around to interfere with it, i have a wireless network but i think WiFi uses a different frequency range than bluetooth
Please help as this is really annoying when typing and a long row of the same letter appears(keyboard acts like its stuck)

I believe that I know how to fix this problem. I had the same thing with the Toshiba Encore.
Found a guy on youtube that explained it, but I must have forgot to save the link.
Go to "Control Panel" --> "System and Security" --> "System"
Then select "Device Manager," That will open a new window with all your stuff.
Now expand "Network adapters"
You should see "Broadcom 802.11abgn Wireless SDIO Adapter." Click that and select the "Advanced" tab.
Now look for "Bluetooth Collaboration"
It will probably be set to "Auto." Select "Disable"
Now your bluetooth hardware will work!

Trackpad/Touchpad acting erratically

I recently purchased a MBP in the end of July. Recently the trackpad/touchpad (whatever you want to call it) has been acting erratically. The mouse will move all over the screen, click on what it wants, right-click on what it wants, zoom in/out on what it wants, and has even been making tons of new folders on my desktop because of it's ability to left and right click randomly. When I try and move the mouse by using the trackpad, it simply freaks out and will not move the direction that I want it to. Any insight onto what the deal is? This started happening a few days after a software update.

This describes my current situation perfectly. I have tried:
rebooted with no luck.
Closed all apps and opened them again one at a time to see if that helps.
turned off wifi and back on.
plugged in wireless usb mouse to not use trackpad, still does it.
I had to turn off all the functions of the trackpad (gestures, etc.) to keep it from switching screens but it's still jumping around. it removed things from my app bar, it sent emails before I was finished and created new folders on my desktop.
Is there something within the macbook that is pushing up against it internally? Haven't been able to find any solutions for this yet.

Can you use the browser and search the web by utilizing a speach recognition program instead of the mouse & keyboard ?

''locking as a duplicate of https://support.mozilla.org/en-US/questions/972710''
I would like to know if Mozilla's ( Firefox Browser) can integrate with and utilize a speech recognition program, I would like to have control of and be able to use all of the browsers functions while navigating the web using voice commands (only) ,instead of having to use a mouse & keyboard. If the browser does have that capability, are there any issues I need to be aware of and are there any tutorials or web pages Mozilla can suggest that will help with this.
Thanks in advance for answering my questions and for the information forthcoming!

What is this speech recoginaziom program called? I need to know if I am to help you. Thanks Nathan.

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.

Mac Acting Erratically: Please help Safari iTunes Messing Up

Okay I have an Apple PowerBook G4 running Mac OS 10.3.9 Panther (purchased late Nov 2003 was originally running 10.2.8 Jaguar) and up till a few days ago everything was running smoothly. That is until after I upgraded to QuickTime 7.1.2 and installed iTunes 6.0.5 when the problem started. Somehow my login.keychain for Safari got corrupted and I tried deleting original and making a new one.
Here's what has happened since then:
Any free media I have downloaded like videos or music off free sites (without Digital Rights Management) already still work. However, if I try downloading new stuff the new files don't work.
Since day before yesterday 4 times when I open iTunes it tells me my Library has been damaged. All my music files are still on my hard drive and are still playable but my iTunes Library file is corrupted -- how and why I don't know.
No music appears in my Library nor do any of my videos in .m4v format (iPod format) show up in my Library since then. I trash damaged file and re-import or select add to library and re-add all the media to my Library seems to work fine. I play them and most of them are playable. Even when Library works a few that played earlier have a skipping problem.
In Safari all my bookmarks got deleted -- I had to back, find the websites and re-add them -- fortunately when I closed Safari and re-launched the browser they remained saved the next time I closed and re-started the browser. However, third time (normally when something doesn't work twice they say third time's the charm) well the third time I opened Safari everything got deleted again.
My iTunes Library is acting erratically -- files I download don't work although files I already have are still playable usually except when my programs run across errors that didn't exist earlier.
I have Microsoft Office X 10.1.6 with the PowerPoint X and Excel X Security Updates, the Apple Security Updates 2006-002, 2006-003 and QuickTime 7.1.2 and iTunes 6.0.5.
When I originally downloaded and installed Security Update 2006-001 my Safari completely broke and would stop running and my Dock Menu dissappeared until restart but even then Safari stopped working. Could find no other solution than reinstalling OS X to return my Mac to pre Security Update 2006-001 levels. Not even Disk Utility solved the problem.
iTunes 6.0.2 also caused problems for me (I heard it caused problems on Windows also) the problem on my Mac was Disk Utility stopped working altogether. Fortunately, by deleting the game Chess from my Mac it fixed the problem. Today, I have Chess back on my computer because since my last OS reinstall I just updated my iTunes to 6.0.3 (I think) I now have iTunes 6.0.5 and have had no problems with Chess and iTunes or iTunes and another application like Chess preventing Disk Utility from working -- but now this problem I am describing where my Library erases itself regularly -- sometimes I restart iTunes and the new user wizard shows up and asks if I want iTunes to find my media and automatically add it to my Library when it does I say yes and it re-adds everything but somehow I have 2 files for every song on my computer and it re-imports (or imports) all my music, videos and podcasts back into my Library once and then re-imporitng it again
This time Safari is working but bookmarks are being erased and re-erased, iTunes is acting all screwy, files I download don't work when they should, I tried deleting and re-downloading a video I had saved on my hard drive (that I downloaded earlier) and the exact same file (no changes had been made to the file when it was re-uploaded) had errors playing when the download completed.
Fortunately, I had burned the video to a CD so I can re-copy it to my Mac and when I play it off the CD on my Mac or copy directly to Mac and play it works just fine.
Since downloading these updates cannot download anything anymore without errors when playing them.
If I downloaded same files earlier though they would have worked.
Only as a last resort would I do a clean reinstall of OS X -- thing is it would take a lot of work just to reinstall OS X, copy all my files I have backed up back to my hard drive, re-importing my music and artwork, re-installing Microsoft Office X and its updates, reinstalling some (but not all the latest ones if neccessary) of Apple's Security Updates, reupdating to Mac OS 10.3.9 to reinstall QuickTime 7.
I had like 283 files in my iTunes Library, including all my music, videos, podcasts etc.
Imagine how long it would take to get them all back in there; and I re-did it last night until it got erased again. Don't want to re-do it unless next time it stays permanently.
Just a note I also have Virex 7 on my Mac -- and it used to be a startup item but somehow it got disabled from starting up.
Also, I do have VLC Media Player but even that has been having problems with playing newly downloaded media files since I updated my QuickTime.
So the problem now is with my iTunes Library erasing itself continuously and even when its working sometimes refusing to play an entire track (it starts playing a song and then skips to the next one) I've checked my preferences and cross shading or whatever its called is unselected but sound checker is on.
Also the problem involves my Safari erasing bookmarks on its own as described above. Please help anyway you can!
As a last resort will do a clean reinstall, re-copy all my files back to my hard drive, reinstall my programs, re-update my Mac carefully etc.

Thanks for the help. I will take your advice and try running Disk Utility again. I have noticed sometimes when running Safari after quitting the application my defaults get changed -- that is my preferences go away. I have popup blocking and tabbed browing normally enabled by default it used to be if I enabled them as long as I didn't manually disable them that they would stay the same even after I quit and relaunch the browser, but now they get disabled when I quit and have to manually re-enable them again.
Also as noted bookmarks get deleted. Since the time I posted this thread I had at one time done a clean reinstall of OS X -- did it about 1-2 weeks ago. Not sure if videos I download on my Mac still have same problem but noticed if I download same videos on a PC that I used to download and play directly on my Mac that I could burn them to a CD or put them on a flash drive and transfer the file to Mac without any problems but downloading directly on Mac and then playing causes difficulty.
However, the same issue with Safari and iTunes has still been lingering for a while. I already have Mac OS 10.3.9 Combined Update installed should I try re-installing again? That would require me to reinstall OS X again and then update to 10.3.9. Or simply re-download and re-install 10.3.9 if possible over existing configuration so installing 10.3.9 over 10.3.9?
3 times out of 5 iTunes Music Library becomes damaged -- a few times I have tried since then deleting files in iTunes cache -- shouldn't become too big anyways -- otherwise it could become slow or something (good reason for cleaning Safari cache sometimes also) of course I wouldn't clean out the entire cache unless I had to or I thought that would fix the problem etc -- unless maybe it would even do a lot of good for resolving the problem.
I even tried trashing the damaged iTunes Library and the iTunes Music Library.xml file when the Library wasn't working.
If the problem re-occurs should I trash the iTunes preferences file(s) like iTunes.plist etc would help?

Mighty Mouse - Mouse/keyboard system preferences gone

I have a bluetooth mighty mouse instaled in my computer but now I cannot access the mouse/keyboard preferences in the System preferences. They do not appear. The mouse is working just fine but I cannot change anything in the preferences. And I cannot watch the state of charge of the batteries either. I cannot see nothing. That tab is all grey now.
I tried also to do so via the bluetooth preferences but when I ask to open the Bluetooth preference of the mouse a window appears and says that the mouse preferences are not shown because I haven't any mouse connected to my computer.
I remember that when I had access I changed the name of the mouse.
I already deleted the connection and tried to re-install it again. But the mouse appears with the same name, and the problem persists.
Please... Any bright soul?

I have a slightly different problem: My bluetooth Mighty Mouse works in a basic mode (primary & secondary button, scroll wheel) but the side buttons and scroll buttons do not work. In the Keyboard & Mouse preferences, I have Dashboard set up for the scroll button and Expose set up for the side buttons. They do not work. If I set up the primary or secondary buttons for Dashboard or Expose, it works. In the Bluetooth tab, the Bluetooth Mouse Name is blank and Battery Level is grayed out. In the Bluetooth Preferences, it shows Mighty Mouse connected. Any ideas? I am running OS X 10.5.4 (but it didn't work in 10.5.3 either)
