Typing and Mouse lag

just in the last two days there has been a typing lag on my computer. it is almost unbearable. i have the same problem with scrolling with the mouse, and occasionally switching between windows.
im really new to macs, and this is driving me nuts! can anyone help me?

I'm afraid that it didn't work for me. My problem started in the past few days, I believe. My hard disk was very full after an upgrade to Leopard, which at least exacerbated the problem because the system became so slow. I cleared stuff off of the disk, which helped the speed problem, but the typing lag is still there.
But it isn't just a lag. Several times a minute there is a delay in which one or two letters get inserted out of sequence. For example, if I type "The quick brown fox jumps over the lazy dog," it might come out like this: "Theq uick brown fox jmups over th elazy dog." These are actual errors. I typed the sentence several times and combined some of the errors into a single sentence: the space after "The," the u in "jumps," and the e in "the" were all delayed. I typed slowly to be sure I didn't type letters out of order. When I type faster, the results can get more bizarre.
Does anyone have any idea what is going on?

Flash Player performance slowness and mouse lag

I've been having this problem for a while. I already did the usual google searching and didn't find anything useful. Specifically its games I play on kongregate and other sites. When they are using flash player I tend to get poor performance. If it uses a mouse cursor the mouse lags/skips across the flash player window, when it leaves the flash player area the lag doesn't occur. I dont have problems when I'm in games or general responsiveness of the system, I've plenty of space, low processor utilization, low memory utilization, etc etc.
I have windows 8.1, IE11, the latest flash player, video and system drivers are all the latest and greatest. I've found articles suggesting to turn on/off hardware/software gpu acceleration in IE, it also occurs in Firefox.
ideas?

Thanks for the suggestion. I'll try this. Which browser (and version) are you using? My question was as much about the performance of Flash player in a 64 bit environment as it was about the video playback hardware performance. I'm sceptical of the shared video memory and throughput performance of the Intel-based 4500HD graphics package in my laptop. I'm worried that it might not be sufficient for full-screen flash video playback, or for large external displays, so I'm trying to explain the poor platback performance that I'm seeing, and hopefully show that it's not the fault of the video HW.
Which video HW do you have in your dell?
Thanks

Trackpad, Keyboard, and Mouse lag after wake up.

Sometimes, I run my MacBook Pro's battery until my computer goes to sleep.
When I plug my computer back in, and it wakes back up to its previous state, the trackpad and keyboard become unresponsive for sometime (Maybe 1.5 mins at most). It's not a huge issue as my computer is still 100% operable when things start to respond again, but it's kinda annoying.
Can anyone describe what is happening?

It could be due to the fact that as the computer charges and comes "back from the dead", it takes a minute to charge it to the point where it has enough power to power your trackpad, keyboard, and mouse. It needs to devote a lot of the newfound power to the screen, which I'm sure you know takes up a lot of battery. Does putting down the screen brightness when you start to charge from 0% batter help?

Typing and Scrolling lags sooooooo much on U310

For some reason, when I'm typing in microsoft word (I'm using 2010 version) or facebook, the typing lags sooooo much. The letters wouldn't appear on the screen until a 2 or 3 seconds after I typed them. It's really annoying since I have to write 10 page papers for school. Also, when scrolling through documents in microsoft word, adobe, or in a web browser, the scrolling is really slow too. I'd keep dragging the scroll bar, but it would pause every 2 seconds. That's super annoying as well. I don't know what's wrong since I don't download apps or programs from the internet, and I haven't instailled a lot of programs on my U310 ideapad. I do search quite a bit on the internet though, but I use McAfee secure search to make sure I'm not clicking on sketchy links. My laptop also boots up really fast, and opening/closing windows is fast too. just got this laptop back in Nov. 2013, and mostly used it for school .... So what's wrong with my laptop?

Hi SakuraL,
Thanks for posting. Was reading through your post and sorry to hear about the issue you faced with your machine. Its really unusual for it to happen the way you described it as I must admit I haven't come across such an issue like this.
However in order for me to Diagnose this further, I was wondering which model do you specifically have? Is it the U310 or the U310 touch version? What about the operating system you;re running, is it the Win8 or Win7? Could you also let me know of the BIOS version you have?
Hope to hear back.
Regards

Mouse (and keyboard) lag! help?

I did a clean install of ML a week ago. After a few days mouse lag began to become a serious issue. The cursor jitters instead of moving smoothly; it freezes until a large side-to-side movement wakes it up; it disappears entirely. A truly irritating situation and VERY bad for productivity.
At first I blamed the wireless mouse (the latest model Apple mouse) and/or its battery charge. A fresh charge did no good. I'm now using a wired USB mouse and the problem remains. It's apparent in all software (at the moment nothing but Safari is running and the cursor just froze for more than a second). Oddly the scroll wheel on the USB mouse seems to work when everything else is dead.
And.. while typing this, the keyboard went dead. The spacebar alone was ignored, then other keys. Then it woke up. Sheesh. What's going on?
It's a 2010 Mini with 2GB ram. I have an 8GB upgrade on order. Will that make a difference to the mouse?

Update: the mouse is actually losing connection to the mini from time to time. It's les than 2 feet from the computer and the battery charge is 100%. Prior to installing ML I never had any issues with bluetooth reception.
(I shut off the bluetooth in my iPhone and iPad to prevent interference, but it doesn't seem to have made any difference).
Am I the only person with this problem?

Mouse Lag and poor performance. Video Card or Power?

Not specifically a FCP question but related. I recently purchased a new rig. Here are the specs.
2 X 2.93Ghz 6 Core/16GB RAM/ ATI Radeon 5870 video card.
I am having very odd mouse lag problems that are quite annoying. I am also having issues with playing sequences in unlimited RT. A guy in our office can play back better with an quad core. In regards to the mouse problem I have tried several different mouse and keyboard issues including a Wacom tablet and I get the same poor results.
Some people say it could be my video card and some say it could be a dirty power issue. I took the rig back to the store and the tech geek in the back said it worked fine for him but when I showed up with the keyboard and mouse to test it he had boxed up the computer and gone home.
Here is a clip of the screen and the weird jumpy jittery problem I am having.
http://pdvpro.com/stupid_mac/
You can see the mouse and the window I am dragging freeze for a second even though I am mousing smoothly and continuously. The mouse and keyboard and Wacom tablet work perfectly on my old Dual Core.
Any ideas?

According to your video, it's happening in Finder, not just FCP,
so it must be something systemwide.
Is there something running in the background, like Spotlight indexing?
System Preferences > Spotlight > Privacy add your disks to be excluded.
Anything else running in the background?
Anything weird connected to your USB?
Also turn off your Airport or any network connection and repeat the test.

I have a major lag between typing and the letters appearing on my screen? Any suggestions?

When the key board appears on the screen I start typing, but there appears to be a major pause between the typing and the letters appearing on the screen. It started after updating my system some time ago. I have an ipad1.

Try reset all settings

Problem with keyboard and mouse pm8m-v

I have gotten this pm8m-v from a freind who knew nothing about computers. He had problems with the keyboard and mouse not responding at start up or just freeze on him. So I check it out, called MSI and even sent it to them, they claimed that there was nothing wrong with the board. So here are the specs of the computer now:
pm8m-v motherboard
2-256MB memory PC-2700 DDR 333Mhz
intel P4 2.6GHz
codegen power supply 300W
gateway CDW
western digital 40 harddrive
the rest is on board stuff
the problem is still there and it is driving me crazy, can you please help?

I had the same problem with the PM8M-V, today as a matter of fact, and I kept getting locked up at the point where I had to hit enter to load the WinXP CD to setup the system. After finding this topic I tried a different keyboard. The one that was being used was a Kennsiington PS2 cheapo, I swapped it for a Microsoft (one of those ergonomic styles and I've had it for a long time) Keyboard PS2, and the problem went away. I'm typing on the Kennsington right now, so it's fine just wasn't liked by the PM8M-V for some reason.

When I disable my left windows key for gameing using Microsoft keyboard and mouse software, I can no longer type in firefox. How can i fix this?

Microsoft Keyboard and Mouse Software that you install with Microsoft keyboard and mice, (latest version) allows you to disable your windows key so that you don't accidentally hit it when gaming. When I take advantage of this feature, I can no longer type in Firefox. Typing in Firefox is completely disabled. Other browsers, windows, applications work, but not Firefox. What is it about the windows key that firefox needs for typing. Strange problem, but annoying because I have to use a different browser while game. Certainly not a deal breaker, but kinda strange.

Brand new Macbook Pro not pairing with Apple Keyboard and mouse!

Hi all, I have a brand new Macbook Pro and an older wireless Apple Keyboard and Mouse (that were being previously used with my imac G5).
Now I want to use these for this macbook. I am finding that they are being recognised but not pairing up?
Do you need to stop the previous pairing with the imac before they will pair with the Macbook?
Or do I need to update specific software? (I would have thought it has all the necessary updates already installed).
I am running Snow leopard.
I have brand new batteries in the keyboard and mouse.
I really appreciate any helpful advice. Sorry if the answer is obvious!
Thanks

Hi there, i had a problem pairing an Apple wireless keyboard with my MacBook pro but managed to solve it.
The default passkey option in Bluetooth setup assistant is 'automatic' which will (if the MacBook can 'see' the keyboard in the first instance) then say something like 'your device may prompt you to enter the following passcode 1234 5678'
Obviously the keyboard doesn't provide any feedback - I went ahead and typed the number and hit the return key a number of times - the MacBook then displayed a 'pairing failed - you may have entered the incorrect passkey' message.
What i was doing wrong was keying only numbers - when i keyed 1234[SPACE]5678 + RETURN pairing worked.
I had thought the 'gap' in the passcode was to make it easier to read, not that it implied a space in the passcode.
Hope that helps.

Keyboard and mouse freeze randomly

My keyboard and mouse freeze up for 2-4 seconds at seemingly random intervals. I could go for a couple hours without it happening, or like now, it has happened twice while writing this. If I'm typing something when it freezes, nothing I type while it's frozen ends up showing up, but if I had hit a key right when it froze, it will repeat itself until I press something else after it unfreezes. They keyboard and mouse both freeze at the same time, it's not one or the other. It has nothing to do with standby like the topic below...it can happen right after I boot up or anytime thereafter.
My hardware is an eMachines M6805 laptop (upgraded to 2GB of RAM) and just a basic Dell USB mouse and keyboard.
I tried searching the forums, but the search box on here searches the entire web for some reason even if I tell it to search TechNet, so I apologize if this has already been answered.

I just had my Desktop freeze whilst I was using Media Player minimised to the taskbar.
I came back to my PC and couldn't use the keyboard or mouse. I plugged in a wired USB mouse and this did not work either. I then used the mouse and keyboard buttons on my MCE remote and still nothing happened, actually something happened as my hard drive
became very busy, but there was nothing happening on screen. I had to reboot to get back to normal operation.
I use a Logitech Bluetooth MX500 keyboard and mouse and have been having problems since I had Windows 7, but thought it was the keyboard and mouse at fault. This is the first time that I have encountered this problem, but I have had problems with the keys
sticking, very annoying when you're in Visual Studio and it goes and deletes a load of code for you because the backspace key was the one that stuck. The cursor also randomly jumps lines occasionally and inserts text where I don't want it. This wouldn't be
such an issue if I was a touch typist and could look at the screen whilst typing, but I am not and only realise the errors when I have finished typing.
Anyway, Mine is a custom built PC(all drivers and windows fully up to date) which ran XP with zero problems:
Gigabyte mboard and graphics card (Nvidia) with I5 processor and 4GB ram.
If this was a USB hub Powersave issue, then I would still expect the hub to wake up when a new device was pugged in, so I'm going to count that fix out.
I'm not sure that the freezing was a mouse/keyboard fault, I suspect that this is more a video driver fault as the computer did become very busy doing something when I used the MCE remote, it's just the screen didn't update to show what it was doing.
I should have looked at the taskbar clock to see if the time had updated, I'll do that next time if it happens again.
I've disabled the Power Save options for the hub that controls the mouse and keyboard, perhaps this will stop the keys sticking and jumping around when I'm typing in Visual Studio.

New Mac Pro (6 core, D700, 32GB), Mavericks 10.9.4, dragging and scrolling lag, overall system bugginess

Since upgrading to 10.9.4 i've been beset with numerous bugs and general odd system behavior.
Previous to this update I had experience lag when using my Wacom Intuos 4 tablet. For example when doing a preview render in Maya the tablet would become unresponsive and laggy. This never occurred on my old Mac Pro 2008.
I noticed there was an update to the Wacom Drivers (6.3.8-2) so I did the update. After updating I've been experiencing dramatically slow screen redraw. So whenever I drag a window or scroll, the image stutters, flickers and lags as it tries to redraw to keep up with mouse position. This makes it impossible to use the computer.
I uninstalled the Wacom drivers and the lag and redraw errors persist. I looked at Activity Monitor to if it was some other system resource like Spotlight that was momentarily hogging resources. The only thing I notice is that the dreaded "kernel_task" seems to be using a lot of ram (1.46 GB) and cpu time (usually at the top of the list). Also, "com.apple.IconServicesAgent" seems to be using a lot of CPU time (usually #2 in the list).
I'm at a loss as to what to do about this other than re-install everything from scratch. I've read through numerous forum threads about the kernel_task issue but nothing seems to apply to the New Mac Pro.
Hopefully someone has some experience with these issues and some good advice for fixes.

Keyboard and mouse not working correctly after installing Windows 8.1

I was forced to upgrade my computer to Windows 8.1. My keyboard worked fine until the sytem did a reboot. Numbers on keypad stopped typing and letters were being capitalized when the caps lock was off and the numbers across the top will only type the symbol above the numbers.
I looked up this problem and it seems I need to enter UEFI settings and disable Intel XHCI mode. When I get into the UEFI settings I cannot make any selection from the startup menu. Both my keyboard and mouse stop working.
Any suggestions?

Thank you for posting a response. Fortunately, I didn't have to try your solution because the computer resolved itself.

Bluetooth mouse lag

So here is the situation: I have a Macbook Pro (early 2009 model) with an Apple wireless keyboard and a Logitech V270 bluetooth mouse. Recently, I've been experiencing mouse lag (to the point where I can hardly even use the mouse anymore). The lag is intermittent, but is there more often than not. I've been pounding my head searching for a solution to this problem, and after scouring forums and trying different solutions, I gave up completely on finding a remedy. But before I threw in the towel, I tried one more thing: I disabled the bluetooth on the Apple keyboard and tested the mouse. To my amazement, it worked perfectly! I re-enabled the keyboard, and sure enough the lag returned. Now that I have isolated the cause of the problem, I was wondering if anyone had a solution that would allow me to continue using both my keyboard and mouse? (I have my MacBook on a stand, so it would be impractical to not have one or the other).
Any help here would be greatly appreciated!

Update:
Upgraded to 10.6.5 - No difference..
Changed/tried all wifi channels - No change to problem.
Tried a Mac Mouse - slightly less effect but still unusable.
Tried a USB BT dongle type mouse (no using internal BT AP) - Same issue
Tried on a friends Wireless Network - Problem only slightly evident - to be expected as this was a slow network at about 1.9MB/s, a transfer speed that does not show the problem.
Tried using a Netgear wireless intBT mouse router - Problem is only slightly evident on Mac Mighty Mouse, worse on Logitech, evident slightly on ext BT mouse.
With the Wireless nw running a transfer at 3MB/s, this Network speed drops down to a very slow speed when the "Set up Bluetooth Device" utility is initiated.
So given that this issue is also experienced by MacBook owners when using BT mouse while doing a File transfer via USB external HDD, or Time Machine. My conclutions are either:
1.
The USB ports, BT chipsset and Airport Chipset are all using the same data bus in the Macbook.
This data bus is not capable of running a high speed, contiguous data transfer in a single direction AND transfer BT wireless data at the same time. Apple Architects may be able to work around this issue by appling higher priority to BT data transfer tasks (Mouse), as it does when the "Set up Bluetooth Device" utility is running.
or
2. The BT wireless hardare is eisily susseptable to RF interference. This dont explain USB drive influences however.
My best bet is to log a Hardware repair request with Apple, as this is indeed a Hardware issue.

Does anyone get the mouse lag with an external display connected via the display port?

You don't describe the problem in great detail. Is this the issue you are describing?
https://discussions.apple.com/thread/4398076?start=0&tstart=0
If so, then, "Yes." I have the same problem. Note that this isn't a tracking speed problem for me, it's a lag between my hand moving and the pointer moving on the external display.
