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?

Apple TV, monitor use and lag time with mouse and keyboard

I purchased an Apple TV so that I could use one monitor to switch between my Mac Mini and my MacbookPro. The monitor is hardwired to the Mini, but the MacbookPro uses airplay. My wireless mouse and keyboard lag with this setup. Is there a way to fix this?

My contacts in Pyongyang and Interlaken tell me you have fallen in the abyss that "The Great Successor,” Kim Jong-un refers to when he goes to DisneyWorld. One is either ‘right’ or ‘wrong,’ never ‘helpful.’ However due to your Stalinist screen name, you’ve been awarded some slack.
I didn’t see a reference to even a clue on the Apple TV site regarding my traumatic technological problem. I’ll be contacting the Grack Granny Smythe force at Apple’s underground facility at La Junta, CO.
There will be a one way, non-stop, sleeper class Lockheed SR-71 waiting for you at Nantucket International if Tech Support for Apple TV denies that Apple TV exists any longer.

Bluetooth Mouse and keyboard STILL Not working can someone help me?

i have an apple Bluetooth Keyboard and wireles mighty mouse. Since i have installed leopard months ago it was working fine but then my mouse and keyboard stopped pairing with my Powerbook it recognises the devices but the refuse to pair i changed the batteries and installed the software that cam ith the keyboard and mouse and still nothing works.
Can someone help me please

After updating to 10.5.2 I am still experiencing problems with my Apple wireless mouse and keyboard. This is a Leopard issue ( here is just one blog on the topic
http://aralbalkan.com/1086 ) in 2005 I purchased a Mac Mini which I love and never experienced a Bluetooth problem till I installed Leopard several months ago, now at least once a week, on average 2-3 times a week, I loose connection with the keyboard or the mouse and it takes awhile to re-establish the connection. I was hoping the last upgrade would address this issue but no such luck.

It sounds like it is time to restore from the backups you made just before making the disk changes.
You can re-partition and restore your backups. If you didn't make backups first (you were warned that it might damage things and to make sure you had a good backup) then you will need to repartition everything and reinstall from scratch...

Should I check the memory cards themselves? Reseat them?
Yes.
Memtest X or Rember to test the RAM.
Reseat is also good.
The iPhone 4 doesn't like USB 1.1 much.
after the update the computer was working well, except for this freeze when ever I connect iPhone.
I'd try USB 2.0 PCI. That's how I connect my iPhone 4s, and have connected all iPhones and iPods, to my G4.
Never an issue.
Can't say the same for USB 1.1.......
The above (previous post) linked PCI card is cheap enough.
Want cheaper, try this:

P45-C51 mobo. Mouse and Keyboard freezes frequently. Please Help !!!

Hi everyone. I just bought P45-C51 mobo a week ago. It was working fine then since yesterday and then frequently today I'm facing a real problem. I'm using Windows 7 Ultimate 64bit. Whenever I start my computer and it reaches the desktop, after a couple of minutes the mouse and keyboard stops responding but the windows is not hanged as I can simply press the power button and it normally shuts down within 5 to 10 seconds. I checked it both with USB and PS2 version of the keyboard but both seems to freeze. I first thought it was something in windows but i think its something from the bios because when i turned my pc ON and went to the bios then there after 5 minutes the keyboard was frozen but the bios was normal as i could see the seconds change on the system information screen. Can anyone please point me in the right direction what could be the cause of this problem. All the specs are as follows.
Mobo: MSI P45-C51 (MS-7519)
Processor: Core 2 Quad Q8400
RAM: Corsair Vengeance 8gb kit 1600Mhz (4x2)
GPU: EVGA GeForce GT 240 DDR3 1GB
PSU: Cooler Master Extreme Power 460 Watt
Casing: Cooler Master Elite 334 Nvidia Edition
HD Primary: WD2500AAKX 250GB
HD Storage: WD10EARS 1TB
Bios Version: 5.7
Cooler: So far none. I'm on air cooling. One CPU fan and two chassis fans.
Temps for CPU are under 40 degrees.
Please help anyone...

Inspect all your USB ports carefully for any visible damage inside the ports itself. Test if a USB device can be inserted smoothly into each one.
As a last resort, remove the MB and test on a non-conducting surface, and remember an anti static bag is not a non-conducting surface.
Have you started your system in safe mode to test the ports ?
Hi Bernhard, Sorry for the late response. This problem was something related to that board physically as I searched and dig inside the motherboard basics in deep I found out that the ICH10 Usb Host Controller was giving me problems or their might actually be some problem with the South Bridge because thats what controls the low power accessories like usb, IDE sata etc... and thats why the keyboard and mouse was hanging. There were some more issue too with that board like Slow boot and resuming from hibernate took about 3 minutes and when I press the power button for the cold power on it usually power on after 3 seconds and some times it happened if i properly shutdown and then again power on it won't turn on (LEDs and fans start but no power on to the system) So i would have to switch off the power supply, disconnect the power cord and then wait 5 minutes and then reconnect and it turn on then.
What i did was go to the shop from where I bought the mobo and told him all the problems and replaced my board with a new one because it was in warranty and bought only eleven days before.
Thanks alot Bernhard for so much your time you spent on helping me on this issue. The new board seems to work great and I can see very significant different in performance and speed.
Two last queries I have if you can help me out. Can you tell me If i can use Cooler Master Hyper n520 Cooler on this board. I have CM Elite 334 Nvidia Edition Casing. And second thing is that the bios of this board 5.1 and the latest is 5.7. Should I care updating the bios version? If yes then do you suggest any hints on how to do this ?
I really appreciate your help you have done so far.

USB mouse and keyboard don't work on HP Pavilion g7 2203sd, Windows 8.1.

It is not possible to use a USB mouse or keyboard on the HP Pavilion g7 2203sd notebook running Windows 8.1.
A wireless mouse used to work (already some time ago), but now wired or wireless mouse and keyboard don't work any more.
I have tried removing USB devices in the Windows Device Manager and let Windows detect them again, but it does not work.
I read somewhere that it might have to do with the xHCI USB controller that is installed.
I tried removing that and connecting the USB mouse but no succes.
I also looked for driver updates or something to disbale in the BIOS (like xHCI), but nothing found for that.
Can anybody help me with this problem.
Thanks!

External mouse and keyboard no longer work after 10.8.5 upgrade

Today I upgraded from OSX 10.8.4 to 10.8.5 on my macbook pro 17". This upgrade caused by external mouse and keyboard to completely stop working. I tried installing the 10.8.5 "combo" install (http://support.apple.com/kb/DL1676) and also tried resetting the PRAM, but neither action had any effect.
I also tried restoring to an older time machine backup with 10.8.4, but could only figure out how to restore files, not the entire system.
I've lost a day of work at this point, I need help... How can I get back to 10.8.4 or get the mouse/keyboard working again on 10.8.5??

Try booting into the Safe Mode. Disconnect all peripherals except those needed for the test. Shut down the computer and then power it back up. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. When you reboot normally, the initial reboot may be slower than normal. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application uninstaller. For each disable/delete, you will need to restart if you don't do them all at once.

Wireless Mouse and Keyboard Install Problem

I am trying to install my wireless keyboard and mouse onto my Mac OS X 10.3.9. My dad had this computer before me and had the mouse and keyboard paired and working. After it was shipped to me, I attempted to pair these again with no luck. THe bluetooth won't recognize either and if i try and run the KeyboardandMouse.pkg as instructed, the icon simply isn't there when I insert the disk. I've attempted to pair using the system preferences, but it cannot locate either the keyboard and mouse. Yes, I do have new batteries installed and the lights do blink when switched on. Any help is appreciated. Thanks.

Hello again:
Try trashing the BT preference file (com.apple.bluetooth.plist) and restarting.
If that does not work (although it will take you a bit of time), I think I would try an archive and install:

Wireless mouse and keyboard won't connect.

I have a windows 7 computer and a wireless keyboard and mouse which connect to one usb receiver.
I was on the computer and suddenly both my mouse and keyboard stopped working.
The mouse lights up a red light but doesn't work. The computer says it can't recognize the receiver.
The usb receiver doesn't have a connect button. Perhaps the button is a sensor type, but it doesn't seem to make a light turn on.
Perhaps it doesn't work because i touched it with my foot. Please help

It would help me greatly if you identified your TouchSmart PC.

Wireless mouse and keyboard not recognized

I know that I have had this issue before, but can't remember what the solution is (old age?) My iMac G5 PPC has a wireless mouse and keyboard (the old apple white one). The iMac came with these as an option but WITHOUT the bluetooth card inside. (I still don't know how this works, but it does). Anyway, the mouse and keyboard were not recognized when I tried to get on today. The batteries are good. If I go to system prefs (using an even older wired mouse) there is no bluetooth option (since no card is present). I don't know how to get the computer to try to recognize both. Any help is definitely appreciated.

HI David,
If the iMac didn't come with Bluetooth software/hardware, then are you using a USB Bluetooth dongle?
And open System Profile (Applications/Utilities)
Select Bluetooth on the left under Hardware. You may need to click the gray disclosure triangle so it faces down. What does it say on the right?
If the Bluetooth icon is in your Status Menu Bar (top right in your screen). Click the icon and make sure Bluetooth is turned on. Then click: Open Bluetooth Preferences and try re-pairing the mouse and keyboard.

Wireless Mouse and Keyboard don't work under bootcamp. Any suggestions?

I installed Windows 7 through Boot Camp. Everything works, but my wireless mouse and keyboard. If I add a wired mouse and keyboard, they work. Have reinstalled Bootcamp a few times, but when I try and add the devices. they are seen, but then can't pair.
Any help would be appreciated.

Well, the 'unplugged' reference was noted earlier and I wasn't sure if you'd get a
better response than a standard suggestion to try the other ideas in this link first
•Intel-based Macs: Resetting the System Management Controller (SMC) - Apple Support
before actually performing the SMC, that is a dragnet kind of catch-all, sometimes.
All of my keyboard & mouse units are USB and I've gone as far as supplying the
mouse and other peripherals with a powered USB hub; so power from the Mac
isn't spread too thin. The keyboard is one of the only items that should be attached
to the USB port; as it has to work on startup pre-boot keyboard shortcuts... Such
as SafeBoot, PRAM reset, and others where you need a live keyboard and BT
may not be up to the task of being ready. Three going on four of my Macs have
bluetooth capabilities for those items; but I can't justify the continual upkeep cost.
Spare USB keyboards and a few extra mouse are handy as troubleshooting tools, too.
There are some USB keyboard references among search results in this linked page:
https://www.google.com/?gws_rd=ssl#q=Apple+USB+keyboard+troubleshooting
Perhaps the SMC pre-reset suggestions may help resolve the issue, if not, try reset.
Good luck & happy computing!

Mac mini loses mouse and keyboard after sleep.

Hi Everyone:
I recently bought my Mom one of the new Mac mini (I'm a PowerBook user myself), and she's running into some puzzling problems which, while minor, are sufficiently annoying as to confuse poor old Mom.
The system egnrally runs fine after you turn it on, until it goes to sleep. After some undefined period in sleep mode, the Mac mini appears to "lose" the USB keyboard and mouse which is plugged into it. If you press a mouse button or a keyboard key a few minutes within the system going to sleep, the system will wake up and both will work. If you wait a longer period of time (say, 20 minutes or longer, although I haven't sat and timed it at all), pressing any key or mouse button does nothing, and you have to wake it from sleep by using the power button. Once awake, the keyboard and mouse do nothing. The only way to get them back is to unplug both of them (the mouse is chained through the keyboard as the other Mac mini USB slot is used by Mom's UPS), and plug them back in so the Mac mini can re-detect them on the bus, after which everything is happy again until the system has been asleep for too long.
Has anyone experienced this? Both the mouse and keyboard are genuine IBM (as in: made by International Business Machines), although are several years old (I bought them when I worked for IBM, and IIRC they were amongst the first models of USB keyboards and mice that IBM offered, if not the first).
In the interm, I've lent Mom my Apple Bluetooth mouse and keyboard, which has (as you would expect) worked flawlessly. This problem may "solve" itself -- I'm hoping to take Mom out later this week to buy her own Apple Bluetooth mouse and keyboard at the Apple Store.
The other problem, however, isn't as easy (or necessarily as cheap) to fix. Again after the system has been asleep for some time, it often (but not always) changing the resolution of the monitor when it wakes up. I have the mini set to use a reasonable 1024*768, but sometimes when it awakes it will suddenly be set to 800*600 or 832*624. Sure, you can change it back, but that's major surgury for Mom (and I'm moving cross-country next week, and won't be able to just "drop by" to fix system problems). The monitor is an Ambra SVGA model (Ambra was a brand-name of inexpensive PCs that IBM sold some years ago), and never had any such problems on her last (Intel-based) system the mini is replacing.
The whole purpose of the Mac mini is to "bring your own" Keyboard, Mouse, and Monitor -- but in our case the keyboard and mouse don't work at all after sleep, and the monitors resolution gets dynamically changed after sleep. Has anyone else encountered this situations, or any solutions? TIA!
Brad BARCLAY

Hey Jan:
I've seen quite a few posts in this regard with non-Apple mice and keyboard.
Well, the mouse and keyboard are quite old -- it could be that they're having a problem dealing with identifying themselves on the USB bus during sleep, or aren't identifying themselves fast enough at wake time. I'll just have to replace them I guess.
I've never seen a sleep resolution switching problem except on a VGA adapter to DVI connection to an old tube monitor.
Well, this is a pretty vanilla CRT monitor circa about 1999, so yeah -- it could once again be an age issue, and the fact that there is a DVI -> VGA adapter involved in the middle.
For worrying about fixing Mom's Mac, setup her remote VNC software (Apple Remote Desktop Client) and use the free Chicken of the VNC admin program.
I am quite familiar with VNC. As much admin as possible will be done by SSH, but I will have VNC in place before I leave. The big problem is going to be the fact that I'm going to be several timezones (and over 4000 km) away, so I won't necessarily be available at a moments notice to help her with this sort of thing.
The CRT issue we might just have to deal with by having her always run it at 800*600 (I don't think she'd really notice the difference, and as her eyes aren't what they once used to be, the slight size increase may be more confortable for her in the long run) until such time they she can afford to buy a nicer display (I did my duty as a son buying her the Mac mini and an iSight camera -- she has to take care of the rest ).

TS3048 I am usng a bluetooth keyboard with my Mac and some of the keys are not working. They are the numbers 1 through 9. I have gone through the troubleshooting for mouse and keyboard and everything looks good. How can I get them to work again?

Hi, I am using a Mac computer that my husband set up. I have worked on it recently with no problems. Today, I am having problems with the bluetooth keyboard not working properly. The numbers 1 through 9 do not work. I have gone through troubleshooting wireless mouse and keyboard issues and everything looks good. Except, when I check the keys on the keyboard viewer, these keys still do not work. The webpage guides me through and at this point I do not know what to do next, because the keyboard is still not working properly. I sure hope there are some experienced people in the community to help me. What should I do?

Hi:
I wish my suggestion had gotten you further.
I do suggest you try to connect the keyboard again. The request for a number is a step in it trying to pair. If it gets by the number, it sometimes takes a little while to get connected. If you are unable to get it connected and want a new one, I have been using Apple Bluetooth keyboards for years - and I like them. The one I have (the newest model) only uses two batteries and is very thin.
Speaking of batteries, if you are not already doing so, you might consider rechargeables. I have a drawer full of them and use a 15 minute charger. I go tired of buying batteries and rechargeables are environmentally friendly to boot. At the moment, I use 2450 mAh Energizers and a 15 minute Energizer charger (all purchased new on eBay at a very reasonable price).
I am far from an iPad "expert," although I have one. If my suggestion below does not help, post your question in a separate thread in the iPad forum.
I had a terrible time syncing my iCal on my Mac with my iPad iCal (confusing - hopefully it makes sense). I quit using iCloud as that added to the confusion. There is a facility to one-time sync items. When you connect your computer to your iPad, iTunes opens. The system begins a process (automatic backup and so on). After it finishes, you can click on "info." At the bottom of the screen, there is an advanced section. You can select any of the items and then force it to sync. The iCal information from your computer would be deposited on the iPad.
After all that, I do not use a Google calendar so the information may be worthless to you.
If you want to reset the iPad to factory settings, you can do that when it is connected to iTunes (one of the options). Me being me, I try never to erase anything.
