Over 100% Maximum Fequency on CPU, but only 10% usage.
After a VERY short while of using my PC, the CPU frequncy can reach 116%, but only 7-10% usage. This causes my PC to stutter and become very laggy for anywhere between 3 seconds and 10 seconds. This can happen twice in one minute or twice in one hour - it is completely random.
I don't even have to be doing anything strenuous.. I might be listening to music with nothing else going and it will happen, or I could be dual screening two games and it's fine.
At first I though it was my HDD, I replaced this and was fine for a few days, then it just went back to stuttering again, I have had this PC for about 18 months, and it started happening just after the warranty ran out. Any ideads?

I understand the CS2 is probably not helping, but there is really a problem on other apps too - not only CS2 and those are universal.
Page ins/outs are currently 142257/71109 and i have not been using or even opening CS2 - just safari, itunes, What size , MSEntourage, VLC and moving some files.
I have taken some earlier advice on your posts regarding using multiple internal disks - so i moved itunes and iphoto libraries to a separate disk and also use that for scratch in CS2. The drives are 250GB WD and 250GB Seagate, and i am looking at replacing them with one or two 750GB WD RE2, although probably not in RAID ( dont want to complicate my life too much in one go !)
Overall i think the page ins/outs look high from my searching in other posts, but can't see why it would be overloaded when i normally dont use the CS2 that much ( only a hobby)
Also the private/var/vm directory has 3 swap files - two of 64 MB and one (Swapfile2) is 128MB, if that tells something else ?
looks like i will have to invest in 4GB more memory as well as the HDD's. i was confused with the apparent further lack of support in CS3 for 64 bit programming (?) although i dont know when that would be launched so soon after CS3
I have a case of a little knowledge ( which can be a dangerous thing!)

ESXI Guest VM is using 100% Guest CPU, but only 7% Host CPU
You're running a very old version of 5.5 so one of the first things I'd do is to install the latest patches.
We have a Dell T420 server running ESXi 5.5. The host has a single E5-2407 CPU (4 Core 2.2 GHz no Hyperthreading), 16 GB of RAM, and local RAID storage. The host runs a single Windows Server 2008 VM, which was a P2V conversion. The VM is currently assigned 1 Socket and 4 Cores, matching the host CPU. Since setting up this server about a year ago, it has had a recurring problem pop up every few months. When the problem happens, the Server 2008 VM suddenly has max CPU usage and terrible performance, but CPU is being maxed not by a single program, but from several normal processes. For example, WMI, explorer.exe, and task manager may all show 30% CPU usage. Meanwhile, though the Guest VM has 100% CPU usage, the Host will show it only using 300-500 MHz of CPU, or about 7% of available. This is despite the fact it's the sole VM and has full...

Why does mail app show over 2,000 messages (not new) but only 10-12 in my inbox?
So I recenly got a new rMBP and have begun using the Mail app. I've had a bunch of problems with Gmail and the app but my my biggest gripe is that it seems to have downloaded over 2,000 messages from the server (of which I have no idea where its getting them because I've deleted pretty much everything in trying to solve this to the extent of completely wiping out my email folders). I wouldn't have such a problem with it except that it seems like its actually downloaded the 2,000+ messages onto my computer, no dobt taking up space (and its mildly annoying to me to always see 2,514 to the right of the "Gmail" folder in the left window)
I have tried emptying my mail completely including emptying the trash+deleting mail account from all apple devices and then restarting them before adding the mail account back.
Looking in random folders to make sure I haven't lost my marbles and theres a stash of emails lurking somewhere...
Again, deleting the accounts, powercycling the apple devices and then setting up mail again (just incase the first three times didn't work) and I'll mention that EVERY time I set up the account it imediately starts downloading the 2,000+ emails all over again (little windw shows up in bottom left counting down how many it has and how many there are left to go).
Any advise would be appreciated- I know its not huge but its driving me crazy!!
Just FYI I'm using the mail app simultaneously on a rMBP, iPad 4, and iPhone 5...Go to Gmail (on the web) look in the folder named All Mail, they will be there, delete what you want.

I bought LR 5 Oct 16 this year. Why doesn't my watermark work when I export photos? I followed tutorials and still it does not work. Once, a few photos out of about 100 exported with the watermark, but only once. Is this a bug? how to fix? Also, how to I get rid of unwanted presents?
Are you exporting as JPG or TIFF or PSD?
Any other format (including "Original") will not show a watermark. -

My Finder keeps grabbing over 100% of the CPU which seems to stop me from opening any folders.
Only quitting the Finder from Activity monitor resets it to normal.
Any ideas?Nope, I don't have a "/Users/charon/Library/Mobile Documents" directory, let alone anything underneath it. Is that like an iCloud thing or something? I tend to avoid the Apple-supplied services when I can (I don't use iTunes either unless I can help it).
As an update, as of about two days later this problem seems to have solved itself. Possibly sleeping and waking did something to it (though that seems unlikely given how many times I rebooted), or else there was just some long-*** kernel process that finally worked itself out. But my system CPU is back down to normal and the cursor freezes are gone.

HT203167 My iTunes had over 100 albums, but now only 5 after an update. How can I get them back?
Like I said, I had well over 100 albums on my computer. These were all imports from physical albums, some of which I don't have anymore. I updated iTunes this morning and now I have 5 albums. I've tried rolling iTunes back to a saved point, but it didn't put anything back in and now that restore point is gone. I thouht I could just search for the albums on my computer and re-import them, but they seem to be wiped from the entire computer. What the heck? Is there any way to get them back?
See this older post from another forum member Zevoneer covering the different methods and software available to assist you with the task of copying content from your iPod back to your PC and into iTunes.

Mac goes over 100 percent cpu usage
As seen in the picture, the game called 'runescape' which i was playing reached 171 percent cpu usage on my computer. My computer never crashed from playing this game but crashes alot while playing Dota 2, once when I crashed from dota 2, the computer lagged showing my activity monitor which showed that dota had 100.1 percent cpu usage. Is this a problem of the game or the computer? Multiple friends of mine have played this game and never once crashed on it.
It is a problem with games in general: they use a lot of CPU power (and heat the CPU up correspondingly). Over 100% is not very spectacular, because modern CPUs have 2, 4 or 8 cores, and each has a maximum of 100%. If you have a 4 cores cpu the run escape is taking almost 45% which is a lot.

I have a Sonos system in my house and suddenly discovered that many songs I bought off of iTunes years ago are 'grayed out' when I try to play them from my iPhone or do not appear as options at all when I try to play them on Sonos from my overall music library. It's well over 100 songs I bought back before mid-2009 when Apple dropped this DRM thing. From what I think I am reading, if I want to play those songs on Sonos, the ONLY way to do so is pay Apple another $25/year for iTunes Match (which I don't have any interest in) and then re-download them all in iTunes Plus format??
Matt,
I agree it was not all communicated real well, but in your case it will work out. You missed the program where you could have upgraded 100 tracks for 30 cents each (=$30) but now you can do it via Match (=$25). It works pretty simply, per this document:
Can I upgrade my previously purchased music to iTunes Plus?
Yes. If you subscribe to iTunes Match, you can download your previously purchased music again in the iTunes Plus format. To do so:
You need to delete the original DRM song from your library first. Doing this enables you to download the song again in the iTunes Plus format from iTunes in the Cloud.
Click the Purchased tab in the iTunes Store.
Click Music.
Locate the artist of the song you want to upgrade.
Click the iCloud Download icon next to the song you want to upgrade.
Just don't forget to put the Plus files on your hard drive -- properly backed up of course -- and to cancel the Match subscription before the second year rolls around! -
Waveform IRE Level Over 100 on Sony A77 but not for Canon T2i
Why does the Sony A77 have a white IRE level over 100 while the Canon T2i max out at 100? You can view this larger if you like so you can see the graph better, http://www.flickr.com/photos/davedugdale/6326846722/.
On my Canon I have highlight tone priority turned off and Auto lighting optimizer turned off as well. Also on both camera I have them set to a neutral picture style and the lowest contrast setting.
I am trying to do a test on which camera can hold the highlights better.
As you can see I matched the skin tone levels on the left by changing the camera settings to match each other so I could see what would happen on the right side where I drew a tree that is heavily back lite.
But it is hard to draw any conclusions when the Sony is "cheating" with higher IRE levels.
I wonder if it has to do with the color space? I don't think so because both are using the sRGB color space.
No transcoding was done to any of the clips dragged on to the timeline. Just "raw" files from the cameras.
The Sony A77 creates AVCHD Video (.MTS) files while the Canon T2i creates MOV video (.MOV) files.
What is interesting is if I use the same clips in Sony Vegas Pro 9, the Waveforms match at 110 IRE. Something wrong with Premiere?
Sony A77 on the left and Canon T2i on the right.

Ichat consumes over 100% CPU in video chat mode.
Hi,
I just updated my MBP (mid 2009) with new Snow Leopard. Ever since then, some of applications hangs, especially ichat, Mail, iphoto, safari.
Is it normal that iChat consumes over 100% CPU in video chat mode? Does everyone have the same problem?Hello all. Ralph, I really appreciate all of your help on these iChat threads. I too am having the same issues with CPU overload on both of my Macbook Pro 2.16 GHz machines. I believe I may have traced the problem to older, non-Core 2 Duo chip computers such as mine. I have an iChat crazy family - lots of us spread across the country. The ones who have newer machines with a Core 2 Duo do not have this problem. They have super crisp, normal CPU usage (never exceeding 80%) chats. Sadly, this is not the case when I try with either of my Macbook Pro's running the older chips.
To clarify, I have also taken all of the steps mentioned here and in other threads to try to address the problem. I have reinstalled Snow Leopard, adjusted the maximum bandwith to as low as 200 kbps, tested my download, upload speeds, etc. Nothing seems to work. Ichat it essentially useless. I wish I had an answer for this issue. I assume Apple will address this in the next OS update. -
CPU running over 100% using Roxio Toast
Hello,
I am using Roxio Toast and noticed that songs are skipping, I checked my CPU and it is going over 100%, when this happens.
My activity monitor show no other programs are running.
Any idea why my computer is running over 100% on one single program?
Thank you,
Bmacsingle threaded and can't be broken up. Most likely written before hyper-threading and not optimized. Don't feel too bad, Apple had trouble also in 2009 and hadn't caught on and had audio code in that would spike processor core and overhead the system and wasn't rectified in 10.5.7+ but took 10.6.2+ to work around.
So what version are you using and is this the latest? And what about any other processes or something? A system can't run w/o lots of other processes, even if you aren't running a main foreground program, plug-ins, background, they all do matter.
My guess is like every thread almost, more input is needed about your system.
By itself it is just being inefficient. -
I have 528 contacts on my phone, but only 290 on my Icloud how can i move the rest over from my phone to my Icloud nothing is working
Go to Settings>iCloud, turn Contacts to Off, choose Delete from My iPhone when prompted (they will still be in iCloud).
Download the app My Contacts Backup to your phone. Use this app to backup the remaining contacts on your phone (from your exchange account) as a vCard attachment to an email that you send to yourself. Confirm that you have received the email on your phone.
Go to Settings>iCloud and turn Contacts back to On.
Go to Settings>Mail,Contacts,Calendars>Default Account (in the Contacts section), set this to iCloud. (This will cause new contacts added to your phone to be added to the iCloud account.)
Go to Settings>Mail,Contacts,Calendars...tap your exchange account and turn off contacts syncing (otherwise you will end up with duplicates on your phone).
Open the My Contacts Backup email and tap the attachment to import the contacts from your exchange account back to your phone. They will be added to iCloud and appear on icloud.com and any other devices syncing contacts with your account. -

I have been purchasing songs from itunes for the past year. I have over 100 songs. I recently got a new computer and I synched the iphone to it. I can't find 90% of my music. Where is it and how can I get it back? I checked itunes under purchased and it only shows 13 songs. Please help.
You can only sync with one computer. When you synced to the new computer it would have erased it and synced what was on the new computer.
You always need to have a backup, an iPhone is not a storage device.
When you get a new computer you need to transfer your library before syncing
If you don't have a backup you may be out of luck
The only thing would be if you're in the US and have access to the iCloud beta to reload purchases
