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.....

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?

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:

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?

My ipad has started jumping from app to app. Games act erratically. Not all the time. Any ideas?

My ipad has started jumping from App to App. Games acting erratically. Doesn't happen ALL the time. ANY ideas?

Close all apps in the recents tray completely and reboot iPad. Go to the home screen first by tapping the home button. Double tap the home button and the task bar will appear with all of your recent/open apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner of the app that you want to close ..close them all! Tap the home button or anywhere above the task bar.
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.

IPad keyboard behaving erratically.

I am using a new 10w USB charger for my iPad and when I try to use the touch keyboard it starts behaving erratically. I touch a letter and other letters appear and when I touch the delete button more letters appear? When i unplug it the keyboard is fine, is this a problem with the charger?

I would try another charger now. Borrow one if you can or take your iPad and your charger to an Apple Store.
If the iPad keyboard behaves erratically with another charger, it could be an issue with the iPad. If you switch chargers and the problem goes away, then I would assume that the charger is the culprit.
Does this make sense to you?
You can also try this and see if it makes any difference. Do this while the iPad is not plugged in and charging. Reset the iPad.

Mac book pro keyboard acting as Option + Shift are constantly pressed

Hi guys,
My MBP keyboard is acting as if Option Shift are constantly being pressed. For example, pressing on letters brings up special characters (pressing k will bring up ). I have tried disabling all the modifier keys in "System Preferences", but the result is still the same. I have also tried installing all updates on my OS (Mavericks). The onscreen keyboard acts in the same manner as the physical keyboard, but an external USB keyboard was working as expected.
Thanks in advance for your help.

I have similar issue: both left and right shift keys time to time being pressed, it disappears after a while...but once I couldn't log in as the shift option puts caps lock on....really annoying.
The only reason in my case is the keyboard cleaning that I have done recently...
There is no quick fix for this I am afraid.
Options:
1.Apple replaces the keyboard you pay around £200 I think....
2. Buy new keyboard on Ebay and replace it yourself £40....

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.

Cursor and the track pad are acting erratically.

I have a 13" MacBook Pro (mid 2012). Currently have Mac OS X Lion 10.7.5 (11G63) install. My cursor and the track pad are acting erratically. Any suggestions. Google wasn't a great help.

Replace your MacBook's battery ASAP.

Palm Pre acting erratically after 1.4.5 Update

After I updated to 1.4.5 a few weeks ago, I lost my bookmarks first. Resetting the phone solved the problem however a few days later all of a sudden it started acting erratically as if someone else was using my phone remotely. (there would be signs on the screens as if someone was tapping on the screen and the browser would open along with other apps or e-mail and when I tried to throw the open screens throw away, they would hesitate and get stuck in the middle of the screen) Another reset seemed to have resolved the problem but yesterday the same problem came back while I was driving and when the navigation was on. The navigation froze and started pointing the sky!
Any suggestions how to fix this problem?
Thanks,
Burak
Post relates to: Pre p100eww (Sprint)

When you say "reset", do you mean you rebooted the phone? or did you use WebOS Doctor to reload the OS entirely?
If you haven't already done so, try shutting the phone down entirely and removing the battery. If that doesn't work for you, then try running WebOS Doctor. It's going to wipe everything. You should be able to get all your apps and contacts back when the phone asks you to log into your Palm Profile. I'm not 100% about whether you'll get your data back or not (pics, music, docs, ect.) so be sure to get your important files off the phone first.
Make sure that you have your Pre's backup feature enabled (it should be by default, but check anyway), otherwise your Palm profile will have nothing to restore.

[SOLVED]Mouse and keyboard acting crazy. I have to restart gdm via ssh

Here's the output from dmesg after boot.
http://pastebay.com/14045
Basically, I'm getting errors from my USB mouse and keyboard. If I wait long enough udev will find them and they'll start working. GDM starts too fast so Xorg is stuck without keyboard and mouse. I had to ssh and restart GDM then mouse and keyboard worked. For the meantime I've disabled gdm in rc.conf.
I usually see these messages from devices that are drawing too much power from the USB power bus.
These devices work fine in the Win32 and OSX installs on the same hardware.
thanks ya'll

Well, my media card reader, an internally mounted one, decided to act crazy. Unplugging it from the mobo seemed to fix it. wonder what happened, it's only 3 months old and has no moving parts

IBook acting erratically - help!

My iBook has recently started to act really strangely. Usually, I am typing a Word document or using Safari when this happens: the screen dims until black, the windows go away (like pressing f11), and "1qaz1qa" is typed repeatedly into any sort of text area I am using. This happens in what I would call "fits," during which I can barely use it. Also, when I am using Safari, it's like I pressed the back button, so I have to re-navigate to the page I was viewing.
This problem is really annoying and I can't really use my iBook when it happens (very often). I recently got rid of the w97 virus using VirusScan. Does anyone know the cause of the erratic behavior? thank you!

Wireless keyboard acting goofy

My iMac is only 6 weeks old, but this yesterday my wireless keyboard started acting up: the delete key now deletes forward rather than backward, the arrow keys skip to the end of the line, even without CMD-arrow, option-arrow does nothing, etc. Any cure for this?

I figured it out--a little piece of something was stuck in my keyboard, jamming the Fn key down, which shifted the function of the various keys.

My laptop keyboard acting really weird

I just bought my computer a few days ago and starting last night, every time I pressed "p", shows "*' and the 0 shows "/", unless I press the fn key and p key at the same time.
Here are some of the other keys that are acting weird:
; shows -
/ shows +
? shows +
Was there some combination key I pressed to change these? If there was, can you *lease let me know because it's getting very annoying.
Thank you.

It sounds like you have one of those standard laptop keyboards that numlock
changes things.
Try pressing numlock again. You might have to press the Fn key too...
