Calling up Dashboard causes iTunes and mouse stutter

That pretty much says it... I use F12 with Dashboard coming up as the overlay, not in it's own Space. With iTunes playing, any song or Podcast immediately stutters, as well as a lag in mouse responsiveness. I haven't gone into a real indepth investigation, except to say that it happens with either Safari or Mail being the currently active app when Dashboard is called up, but also when iTunes is the active app.
Thanks in advance for any thoughts.

No, it's fine with one DVI connected display. Disconnecting either the DisplayPort to DVI adapter from the computer or unplugging the second monitor (Samsung) from the electrical outlet eliminates the problem. As long as the second monitor is powered on everything is ok, it's turning off the second monitor that causes the mouse skipping.
There is more on it here if you're interested...

(This one is not a "new" problem or necessarily related to Lion, as you can see since the first post was from 2009, which coincidentally was the year DisplayPort appeard on Macs if I'm not mistaken).
The problem exists even if iTunes is not open, I recently realized as my mouse has become way more accurate on the desktop! Having iTunes open does make the mouse skipping 10X worse though!

Mac OSX 10.6.7 update causes iTunes and entire system to be unresponsive?

Hey all,
I updated to the latest OS X patch today and I've been having problems with iTunes crashing the system ever since.
iTunes would open and the entire system cease to be responsive: the mouse cursor does not respond to movements on the touchpad and the functions keys no longer do anything.
Is this a problem that anyone else is experiencing?

Sam problem here, all use of the latest iTunes freezes my whole computer, this has never happened to me with OS X before.
But I have friends who are not having this problem, so it is not affecting everybody. Could it be some other installed app that causes this?
Is there any simple way to downgrade to 10.6.6?

Faulty Synaptics Touchpad Driver on Split x2 13-m121sa Causing Freezing and Mouse Unresponsiveness

Edit: I found a solution, scroll further down. I have been having problems with my new Split x2 similar to those already explained in the forums by other users. The symptoms are as follows:
1. Unusual hanging or freezing of the mouse pointer on the screen and temperamental use of gestures (two finger scrolling, zooming, etc.)
2. Slowing down of computer generally; acting sluggish and freezing during only light use and/or after screen being closed.
The symptoms seems to change depending on the length of time the computer has been switched on, and are affected by disconnecting/reconnecting the screen from the dock.
Being quite good with these things I decided to investigate and have uncovered the following:
The root cause of both of these problems is the Synaptics Touchpad driver. While the newest version (17.0.10.9) available from the HP website seems to solve any unusual freezing of the pointer it has a significant memory leak. In other words, as you move the pointer around the touchpad uses up the computer's memory. This is normal, but the problem is that the driver for the touchpad does not give the memory back; it cannot be reallocated. This means after a couple of hours of using the computer (or having the screen closed) the memory reaches saturation point and the computer grinds to a halt. If you are having the same problem have a look for yourself: Open task manager and look at the performance tab. Under the Memory heading you will see a value for 'Non-paged pool'. With the computer idle this number shouldn't increase, but move the mouse around and you will see it gradually go up without returning. I have confirmed this to be the Synaptics driver by using the Windows tool poolmon.exe - the culprits are Irp and SynT. Regarding solutions, I have tried many - but there is no absolute fix.
You can uninstall the Synaptics Touchpad driver and the problem will go away - no more freezing or high memory usage. But without the driver the computer reverts to using the standard Windows driver - therefore there is no multitouch gestures like scrolling or zooming.
I have tried installing the generic Synaptics driver available from their website, and the computer won't allow it. Regardless of this, I forced the driver install but the generic driver does not work with this Touchpad anyway (Error code 10). I have tried the latest version (17.0.19) and an older one (16.2.21) with no success. Even earlier versions (e.g. 15.x.x) refuse to run on the grounds of incompatibility. HP Support suggest a system 'refresh' back to factory setting, but apart from the huge inconvenience of time and losing files - I know this won't work either. Apparently a clean install has worked for one user - but for this you need a Windows install disc or USB which I do not have - and I'm sceptical that it would work anyway.
So now I'm using the standard Windows touchpad driver without being able to scroll, zoom or use the swipe-in gestures of Windows 8.1.
If a HP representative is reading this, I would strongly suggest that this problem be escalated. A simple update from Synaptics could solve this problem which is causing people's computers to freeze up and wasting your support staff's time.
TL;DR: HP's Touchpad driver is faulty and causes a memory leak. Synaptics own generic drivers do not work. And Windows standard drivers are unsatisfactory.

SOLVED!
Through my own research I have found a solution. While the official newest driver listed under this model is 17.0.10.9 there is in fact a newer version which does not have this problem: version 17.0.10.16!
I am still disappointed that HP didn't suggest this solution themselves, considering this driver was published back in November 2013! HP if you're reading this: please allocate this driver to this model in your support pages. Anyway, the solution is as follows:
1. Open the Device Manager (Control Panel -> Hardware and Sound -> Device Manager)2. Under 'Mice and other pointing devices' open 'Synaptics HID TouchPad'3. In the 'Driver' tab click on 'Uninstall'4. The pointer will disappear - reboot the computer5. Download the new driver from here: http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?cc=uk&lc=en&softwareitem=ob-127354-1(if this link goes down try searching online for 'synaptics driver 17.0.10.16')6. Open and install the driver I hope this helps. HP, please send my consulation fee via PayPal(!)

Why is the iTunes Match setup process causing iTunes (and my machine) to freeze?

I purchased iTunes Match several days ago, and it continues to freeze iTunes, subsequently locking up my machine. It keeps getting stuck on step 1 of the setup process (analyzing my library); I have left it overnight several times with no luck.
At this point, I really just want my $25 back, but has anyone else encountered this problem? Is there a workaround?

it's been confirmed elsewhere that: once again, itunes IS in fact the problem.
many kudos to Apple, my hat tips to their engineers for being such brilliant programmers. and i'd also like to take this opportunity to thank them for the numerous other times i've had problems with Apple-written software on my windows-based pc's....
Go Apple, yeah !!

Ipod causing iTunes and Finder to be unresponsive

When I plug my 15gig 3rd generation ipod into my iMac (OS10.3.9) it shows up on my desktop but I cannot update my iPod. The spinning beachball appears. iTunes does not operate properly, the ipod does not appear in the playlist column or in the Preference window and when I try a Force Quit, sometimes iTunes shows as "not responding" (I thought only Microsoft products did that) and sometimes I have to Force Quit iTunes 4 and 5 times before it quits. iTunes only seems to misbehave when I try to sync it with my iPod. What is going on???
Paul

used a USB cord. reset to factory. reinstalled latest OS. Now the iPod works with the firewire.

Fix for iTunes and Stuttering Audio Upon Opening Other Programs

This was answered for me in another mega thread, so I thought I would create it's own topic in hopes of helping as many people as possible.
This is a fix for those that have the problem of iTunes 7 working fine alone, but when opening another program such as a game, etc., iTunes 7 begins to stutter and crackle. This fix assumes that otherwise, the program works correctly (gapless, and other issues are not a problem, no blue screens of death, etc.)
First off my machine:
Dell XPS 3.4 ghz Pentium Dual Core
2 Gig RAM
Creative SB X-Fi audio card, latest drivers installed
Observed problem:
Running iTunes 7, audio sounded fine, but opening another program such as UT2004 (first person shooter game) caused iTunes 7 to stutter and crackle.
This was not an issue in iTunes 6.05. I had to upgrade as I just purchased the new Nano.
As an aside, I have another sound card on my computer, an older Layla Echo 24 professional soundcard, drivers are about 3 years old. When selecting this card, this problem does not occur.
The Fix:
Close iTunes 7
Upgrade your sound card drivers (just to eliminate that as an issue)
Upgrade to latest Microsoft direct X version:
http://www.microsoft.com/downloads/details.aspx?FamilyId=2DA43D38-DB71-4C1B-BC6A -9B6652CD92A3&displaylang=en
Start
Run
Type: dxdiag
Click "sound 1" or similarly named tab
Slide bar to "basic acceleration" (mine was at full, and basic is two clicks to the left)
Exit
Restart iTunes 7, and startup music
Open game, or other program
Your music in iTunes 7 should now be stutter/crackle free
This may not work for everybody, but it worked for me so I thought I would pass this along.
Good luck!
(resisting urge to type some snarky remark to Apple that somehow their programmers are indeed as human as Microsoft programmers)...oops...sorry about that.
Dell XPS Windows XP Creative SB X-FI Audio Card
Dell XPS Windows XP

i was hopeful, but it didn't work. well teh one thing that i had to do diff was the dx updating, WGA doesn't like to work on my system for some unkown reason (yes it was bought at a store) so i found a way around their WGA check for it (i think) the one i got was labeled as dxwebupdate for august 2006. it updated just fine and it looks like it should be the same one as the newest update release microsoft sent out
my system is a home built one and haven't had probs with itunes with any other version, until this one. i'm tempted to just go back to the newest version 6 i have, cause this is rediculous. i can't do anything without it sputtering away at me. i tryed uninstalling it and removing every trace of its exsistance off of the system (including registry) and that didn't work i made sure all numbers were set to the correct values for my sound blaster audigy gamer, i was using some non oem drivers, but switched over just to make sure witht eh newest ones creative had, and it made zero diff.
i'm wondering if it is an issue it is having with sound blaster cards...
well anyways if anyone else has any ideas i would like to hear them

Very Confused about iTunes-purchsed Music Videos in iTunes and on iPod

I've searched and searched but can't seem to find previous discussions that address my questions about iTunes-purchased music videos.
I would call myself an experienced iTunes and iPod user. I have no problems working with music, movies, TV shows...
Here are my music video comments and questions:
Why don't I have a Music Video playlist on iTunes but there is one on my iPod.
How can I create a music video playlist?
Why does my iPod Classic show multiple copies of the same music video in the music video playlist and in the general music list?
That seems like a good start. Any and all comments, suggestions, etc...GREATLY appreciated.

*How can I create a music video playlist?*
In iTunes go to File>New Smart Playlist. Match the rule "Video Kind">"Is">"Music Video"
Check the box "Live Updating"

Converting to MP3 causes iTunes to Not Respond while using 50% CPU usage and makes my computer stutter

Anytime I attempt to "Createa an MP3 Version" of a track, it will take a REALLY long time to work.
Right now I am attempting to convert an audio book I have which has 88 tracks. Once I start to convert anything more than 1 track at a time, iTunes immediatly becomes "Not Responding" and takes up about 50% of my CPU the entire time. It seems like it's doing something in the background but it won't even update the screen anymore, creating weird effects on my screen (Ghost menu bars show up at the top of my screen, etc.). In addition, once iTunes becomes non-responsive, my entire computer starts to "stutter" meaning that every other second everything momentarily hiccips and stop for a split-second. This means that while iTunes is converting any multiple MP3 files, if I drag the mouse across the screen, it stops every other second. Any videos that I try to play pause every other second briefly. Basically, my computer becomes almost unusable. Plus, while iTunes is working in the background, different programs randomly jump to the front of the screen. I will try to be using my web browser while iTunes is working in the background. Then, suddenly, iTunes pops back up to the foreground in front of my browser (put still won't be responsive to clicks). My notes program will also flash windows in front of my web browser while surfing, again, only when iTunes is running in the background.
I really don't understand:
1. Why it takes so much time to convert any file to an MP3 file. Even converting a single track takes a few minutes. I'll let my Macbook Pro (with Windows) sit for HOURS upon hours trying to convert the 88 track audio book and it always freezes up and never comes back.
2. Why iTunes becomes non-responsive so quickly and won't allow the screen to update once it starts "thinking." It caps out around 50% of my CPU power so it's not like it doesn't have the headroom to refresh the screen while it works.
3. Why does iTunes' working in the background affect every other program I am running? I don't mind if it uses up CPU cycles in the background, but if it makes my computer unusable while doing so, it's really not worth it.
I should state that I love Apple products (even though I use Windows on my MBP for school purposes). However, I absolutely DREAD having to do anything with iTunes anymore because it has become such a hog on my computer. Someone please tell me that there is something wrong with my iTunes and/or a setting I should change. I have already re-installed iTunes from scratch before and that didn't help.

Not a solution, but if the Podcast feed is dormant, why not unsubscribe?
As to the file structure for media on the device it is deliberately obscured as a countermeasure to casual piracy. See Recover your iTunes library from your iPod or iOS device. Content put on the iPod by a non-iPod aware product is going to treat it like any external drive. The iPod firmware won't read that media.

IOS5.0.1 constant error "iPhone can not make or receive calls. Restore from iTunes": I get this message and the phone will no longer work (happend once while on airplain mode and now once while in wifi only area, out of cell range). help!

All- I get this message ("iPhone can not make or receive calls. Restore from iTunes" (happend once while on airplain mode and now once while in wifi only area, out of cell range)). iPhone 4. Newest OS. Never happened with old OS! Cycling phone on/off does not help. Ignoring message causes phone to cycle off then on. After first time this happened, I restored. Six days later...same problem! Clearly a new fix is necessary. Suggestions?

I have not tried that...I will look up the process so that I can do it correctly (and still transfer all of my files, contacts, etc). Any suggestions? What is the advantage of restoring as a new device..is this more akin to a complete wipe of a hard drive?

ITunes causing computer and everything running to freeze

When I open iTunes, and start selecting music it freezes my computer, my mouse placement, I mean everything for a couple of seconds
When I change songs, search songs, or do whatever with iTunes it causes this
I've made about 4 threads about this before in the past, and it was never helped
It's extremely annyoying, and I would really want some help

Third-party, meaning not from Apple. For example, I have a plug in installed that allows me to control iTunes playback from my menu bar, without having to go to the application or the mini player. Sometimes if you have a plug-in installed, and you update iTunes but not the plug-in, you can run into some weird issues.
Regarding the speed of your USB, if the computer is relatively new, you should have USB 2.0. I have a 6 year old eMachines computer that has 2.0 on it. When you connect an iPod/hard drive to the computer, do you receive a message stating "this device can perform faster"? If so, you have USB 1.1. You can also check this in your Device Manager (right-click on My Computer and click Manage, select Device Manager in the left, scroll to Universal Serial Bus controllers on the right, click the + to expand it, and look underneath). Usually, you'll see something that says "enhanced" or "2.0" to indicate that this is what you have.
You may also want to look into any documentation or support information for your hard drive to determine its speed. If it's a slower RPM, it might be causing some lag.

Mouse and Audio stutter/freezes with Intel ICH9R AHCI drivers

edit: Initially (in original post) I suspected the random mouse and audio stutter/freezes were from a driver update. However between a reboot during these updates I had disconnected an eSATA cable from a drive that was not powered. It turns out the ICH9R when running in AHCI or RAID mode with appropriate drivers installed has problems with some HDDs when the drive isn't powered but the SATA data cable is connected. This is quite normal in SATA enclosures which I have plenty.
What makes this more puzzling is that the stutter/freezes are very tiny and hard to notice IF you don't have any PCI cards connected. With a Intel 100 Mbit PCI NIC connected these stutters became real blocking issue that would have prompted me to return this Gigabyte G33 motherboard (Also affects P35) to the shop had I noticed this issue sooner. I'm not yet sure whether this stutter w/ AHCI/RAID issue affects only the Gigabyte boards but what is certain is that it does affect these in quantity based on how there's others reporting the exact same issue if googling around.

This issue has been confirmed not to be limited to just my system.

Same problem here, it's not limited to Vista, also happens on XP/2003 both 32/64 bit. I'm 99% sure it's to do with the Intel AHCI/Matrix storage driver. It'd be interesting to know what your motherboard brand/model is. Mine is Gigabyte DS2R and I've seen reports of this issue on other forums as well. I'm using the integrated Intel graphics and every component is Intel except Audio Realtek and Network Broadcom. The issue goes away by disabling AHCI/RAID but you lose hot-swap of SATA drives and NCQ.
The primary indicator for this issue is that if any of the SATA ports has a drive that is plugged in but not powered up (and not powered down by the AHCI driver programmatically) then you get this global stutter/studder/hickups/choppy. In audio it sounds like tiny repeats. How bad it is seems to depend on what drive brand is plugged in etc so on some combinations it's very tiny and doesn't happen that often, on other drives it's more constant and easy to detect.
I'd suggest you report at:

btw. My AHCI BIOS/OROM version that is shown on boot with AHCI/RAID enabled is iSRC 1.07 08042006, what's yours?

Though most posts in this thread involve laptops and many of them attempt to isolate the problem in wireless network adapters, let me assure you the same problem can show up in a desktop with wired-ethernet-only. (Admittedly, it's a Realtek onboard gigabit LAN, and Realtek has been fingered by a number of you for its drivers, at least its audio drivers.)
On a brand new core2-quad P35 chipset machine with 4GB ddrII, with a completely clean install of Vista 32 business, I have been suffering intermittent global stuttering. It affects not only audio (of any sort, through any player, whether or not dsp-enhanced) but also video (you can see it in screen saver motion, for instance) and even cursor or mouse movement (hit and hold the spacebar in a text editor and watch the stuttering fun begin!). It's intermittent but not random; that is, it can disappear for a while after I apply one of my stab-in-the-dark fixes (read on) but can come back and then generally remains until I re-apply a fix. It's been like this since about day 1. Well, maybe day 2 or 3.
I've seen so many variants of this problem posted in so many forums, with so many theories, that I could spend the next three months doing nothing but troubleshooting it, assuming I had the budget and time to try endless substitute components or re-builds from scratch, but there's no assurance any or all of that would actually fix it. I do have the Intel Storage Matrix AHCI drivers pre-installed, and Intel itself vaguely alludes to possible 'degraded performance in Vista' with regard to those drivers--is this what they're talking about? They don't say. I do have an Nvidia 8800gts, and Nvidia forums are full of complaints about unacceptable issues with their video drivers, but again it's vague, no smoking gun for global stuttering. I have tried THREE different audio configurations--the onboard realtek hi-def; an x-fi elite; and a c-media based Omega Claro card. I have the problem with all of them. Discovering how musical the c-media card is was a happy accidental side effect of this miserable odyssey, but it really just makes it more frustrating, since I now want to listen to music more than ever but can't find a permanent solution to this vexing problem.
One of the weirdest symptoms is that the stuttering can re-appear (if it has been gone for a few days) just by connecting an external SATA drive, even if the drive is not turned on! Equally weird: simply going into the BIOS and just looking, changing nothing, exiting without saving, can cause it to reappear upon re-boot!
And to ice this cake of weirdness, here are some things that can make it go away (sometimes, at least for a while): removing the external SATA drive and rebooting; removing and re-seating the cards on the motherboard; and clearing the BIOS (jumper or pull out the battery) and then re-entering all the same settings as were there already.
The symptoms are driving me nuts, as audio is one of my main uses for a computer, but it's the HUH? quality of these various actions that can seem to make the problem disappear or re-appear that are really threatening my sanity. If anybody can sift a better clue out of these ashes of frustration than I can, I wish you would post it.

With Windows Vista, the most recent Itunes update 1/30/2014 has caused Itunes not to work, with a Mscvr80.dll not found error. Uninstalled all Apple programs, and installed fresh Itunes. Same problem. Tried to reinstall using an older install exe nogo

Recent ITunes update has caused ITunes not to work. Tried uninstalling all Apple products and reinstalling fresh. Still doesn't work. Tried reinstalling from an old install.exe. Install went nicely but program won't start as it says it can't open the library file.

Now that I have no way of accessing any of the products I have purchased from ITunes, I will most certainly never use ITunes again for any reason. Why throw good money after bad? I will use another MP3 player that is not as cumbersome or proprietary.
Lesson learned.

I tried to sync my iPod touch to a new laptop and it deleted all of my music and videos. I called tech support and they told me to email iTunes and they would give it back to me. How do I do this??

I tried to sync my iPod touch to a new MacPro laptop and it deleted all of my music and videos. I called tech support and they told me to email iTunes and they would give it back to me. How do I do this??

Correct. When you update via iTunes all synced media that is not in your iTunes library will be lost.
As IO said before:
You can redownload most iTunes pruchases by:
Downloading past purchases from the App Store, iBookstore, and iTunes Store
I do not think it included audio books.

I started downloading a song from iTunes and then stopped it in the middle of the download cause it froze, but when I tried to redownload it, iTunes said the song was already downloaded. But it does not show up in my music library on my phone. Help?

I bought a song on iTunes and it started downloading but then about half way through it seemed to stop downloading so I pressed the square stop button in he middle of the downloading circle so that I could try and restart the download. But when I went back to iTunes, instead of having the cloud and the arrow to let me download the song from the cloud next to it, it said "Play" as if I had already downloaded the song. So I went back to my music library to try and find the song but it's not there and iTunes isn't letting me download it cause it says I already have it. Please help.

Safari, iMail, iTunes, and Dashboard won't open

A week ago, Safari, iMail, iTunes, and Dashboard won't open but other applications will, like Mozilla, iPhoto, Word, Excel, etc. Does anyone have any ideas of how I can get Safari and the other programs to open? Thanks for any help you can offer.

Hi, I'm replying to myself to add more information on my case. I wasted half my day yesterday trying to fix this, looking into forums and trying to talk to people about it and there it absolutely no answer. Yesterday I installed the programs necessary to sync my phone in my wife's macbook and nothing bad happened. So I'm guessing it isn't about the phone plugins I installed. I've tried to download combo updates but they crash as soon as I try to install them - I even tried to install a 10.4.10 update.
This is the error message I get:

I did it just in case and, of course, it didn't work. I repaired permissions a million times already, I rebooted in safe mode, I scaned the computer with apple jack, I verified the disk with diskutility - which showed nothing. I tried downloading an anti-virus (ClamXav), but I couldn't open it also, I trashed my prefs, I deleted all internet plugins, but still.... nothing. I'm about to quit and take it to the very expensive - yet reliable - authorized tech support apple has in Rio. Any ideas, anyone?
