Print Manager App consumes over 99% of CPU and fans are constantly on.

Hi!
In Activity Monitor there is a Print Manager App taking over 99% of CPU resources and as a result, fans are on at full speed constantly, even if NOTHING is open. The user of this App is "_lp".
I understand that "root" and "myname" should be the only users.
The machine is a laptop that I use by myself (or so I though).
Are the above signs that somebody/something got inside my machine? I have also discovered MacFUSE in my System Preferences and I know for sure that I did not installed that one.
Any ideas or suggestions?
Thanks.

Force-Quit it. If it comes back on, post back and we'll see if we can figure out why.

Those are the most common, but OSX has any number of internal users for various processes.

Doubful, but anything's possible. A Google search says it's a developer tool. Could be associated with some other 3rd-party app you've installed.
Is your firewall on? With the most restrictive settings?
Has your Mac been left unattended?
Do you need a password to sign on?

Dock consumes 100% of CPU and fan runs. What to do?

I have a 2010 MBP with SSD and VMWare (not Parallels). Every so often, the dock cranks up to consume 100% of the CPU, and the fan runs. The problem goes away when I reboot. I've tried quiting various applications, but it doesn't seem to make a difference (i.e. I cannot identify a rogue app that's causing this). There are a lot of discussion threads on this problem with OS 10.6.8 and Parallels, but I'm running Lion 10.7.1 and VMWare (which I've shut down).
Any others have this issue? Ideas for solution?

Small update: Despite my intelligence, good looks and vast experience I use Google sometimes. To my surprise this file turns out to be a Windows one. Here is someone who is much happier, and since it is some way in my line of thinking I'll quote it, but you might take my previous advice as well:

Firefox does not open when clicking on the icon, the firefox.exe process consumes 99 % of the CPU and my computer runs slowly.

I have been a happy user of Firefox for many years. Around last April first I opened Firefox and was offered an update to v 4.42.0.0 which I accepted. Installation seemingly went well. I forget now exactly what happened but the result has been that ever since April 1 I haven’t been able to open the Firefox browser when clicking on the Firefox icon. My computer now was running very slowly. I tried to uninstall Firefox, but a popup told me I couldn’t because Firefox was in use. This confused me because I couldn’t see it being used. Only now I have found that on Task Manager processes that “firefox.exe” was consuming 99 % of the CPU. After removing firefox.exe by clicking End Process my computer ran better. I uninstalled Firefox I had on my computer and installed Firefox 5.0. Unfortunately I have the same problems: Firefox does not open when clicking on the icon, the firefox.exe process consumes 99 % of the CPU and my computer runs slowly.

Born2die! Brilliant. I am a desktop clicker and never knew Firefox had a safe mode.
Thank You!
I was unable to start in safe mode initially. The second time I disabled all of the Add-Ons and she started up just fine. I enabled them one by one hoping to track down the culprit but the problem seems to have gone away.
BTW I am running ver. 3.6.8 (in response to cor-el's earlier post) and
Firefox is in the process of downloading 3.6.10 (which I am starting to think may have been what caused this whole problem to begin with)
Incidentally, whats up with all of the Java Console Add Ons?
I have:
Java Console 6.0.11, Java Console 6.0.13, Java Console 6.0.15
Java Console 6.0.17, Java Console 6.0.20, and Java Console 6.0.21
What are they? Do I need them? Can I uninstall them? Is this due to using Open Office?
Also, .NET Framework 0.0.0 Should I uninstall it?

The kernel is using excessive processor cycles. Below are some possible causes for the condition.
Throttling
When it gets high temperature readings from the hardware, or low voltage readings from the battery of a MacBook, the kernel may try to compensate by interrupting the processor(s) to slow them down and reduce power consumption. This condition can be due to:
☞ a buildup of dust on the logic board
☞ high ambient temperature
☞ a worn-out or faulty battery in a portable
☞ the malfunction of a cooling fan, a temperature sensor, a voltage sensor, or some other internal component
Note that if the problem is caused by a sensor, there may be no actual overheating or undervoltage.
If the computer is portable, test with and without the AC adapter connected. If kernel_task hogs the processor only on AC power, charging is causing the machine to heat up. That behavior may be normal for some models. CPU usage should drop when charging is complete.
Apple Diagnostics or the Apple Hardware Test, though not very reliable, is sometimes able to detect a fault. For more thorough hardware testing, make a "Genius" appointment at an Apple Store, or go to another authorized service provider.
If nothing is wrong with the hardware, then whatever you can do to improve cooling may help.
Installed software
User-installed software that includes a device driver or other kernel code may thrash the kernel. That category includes virtualization software, such as Parallels and VMware, as well as most commercial "anti-virus" products. Some system-monitoring applications, such as "iStat," can also contribute to the problem. You can test for this possibility by completely disabling or removing the software according to the developer's instructions, or starting in safe mode. Note, however, that disabling a system modification without removing it or testing in safe mode may not be as easy as you think.
Corrupt NVRAM or SMC data
Sometimes the problem is cleared up by resetting the NVRAM or the SMC.
External display
Connecting an external LCD display to some MacBook Pro models while the lid is open may cause this issue. If applicable, test by closing the lid or disconnecting the display. You might get better results with a newer LED display.

Mds and mdworker are constantly using 10%-40% of my CPU since partitioning.

2 days ago I partitioned approximately 80GB of my 500GB 7200rpm macbook pro drive to be used for Windows 7. There was 430GB of free space on my HDD at the time so I know that there was no overwrite issue. It has successfully been installed and runs very well. However, since I did this the mds and mdsworker processes on the Mac side are constantly using large amounts of my CPU and are bogging down my computer. I understand that these services help create the Spotlight database. Is anyone aware of this issue?

After two days I'd say it's time to start over. Go to the System Preferences application- you can get to it by clicking on the Apple in the upper right corner, System Preferences is about a third of the way down the menu. When it's open, select Spotlight from the list of preferences. Under "Search Results" in Spotlight you will see the order in which results will be displayed. If you want to change the order, now would be a good time.
Uncheck all the boxes, this will remove them from the consideration of Spotlight. Then re-check the ones you wish to be available in Spotlight, this will force them to be re-indexed. My arithmetic says your files should occupy not much more than 50 GB, this should not take long to index.
You could try just Applications, or just System Preferences first to see if it is able to complete the task. If it takes longer than a few minutes, there's likely something else going on, perhaps related to your partitioning.
Good luck! Joel.

I can print from my iPad but not my iPhone and they are synched to each other

I can print from my iPad3 (to an Epsom printer that is AirPrint enabled), but not from my iPhone4 (get message saying that the iPhone cannot frin an AirPrint printer). My iPad and iPhone are synched to each other. Any ideas?

make sure your iphone is connected to the same wifi where the printer is connected.

Very high CPU and fans running fast in idle state on 2008 non-unibody Macbo

Hi everyone,
I recently purchased a 2008 MacBook with 2.4 GHz, 2GB RAM, and 160 GB hard drive off of craigslist. Now when I turn it on and leave it idle or even run any activity, the CPU skyrockets to around 66% and the fans are running very hot and fast. I checked activity monitor and nothing is running that indicates this high CPU. This MacBook does have AppleCare on it until August 2011 and I will probably bring it in to have it checked out but would like to know what you think.
Thanks!

ok the abttery charges to 100% now so its alright but sometimes the charger turns to a dim green for some reason and doesnt stay bright only until I unplug and plug it back in again.
in regards to the random CPU spike, here is a screenshot of activity monitor, hopefully you guys can tell me what mds is..

Is there any way that I can share an in-app purchase over multiple devices even if they are under the same iTunes account?

So there are several iOS devices in my family and on one of our iPads we have purchased an in-app purchase. I also have the same app on another iPad and would like to also have access to that in-app purchase. Both of these devices are under the same iTunes account so is there a way to share this in-app purchase across multiple devices?

You can check here > iTunes Store: About In-App Purchases
But I don't think this is possible.

Software to Monitor CPU and Fans

I have an MSI 785G-E53 with a Phenom II x2 (with all 4 cores unlocked).
What program can I use to monitor the CPU core temps, fans, maybe even the hard drives too?
I tried both speedfan and coretemp and neither looked like they pulled the CPU core temps, but maybe I was doing something wrong.
Should those work? Is there a better utility to use?

Quote from: lexluthor on 11-December-10, 21:18:02
Is that because I have the cores enabled? Are you saying that if I didn't do the core unlock, those apps would work? There's something about unlocking the cores that's "breaking" those apps?
Yep, exactly that. I had the same thing when I unlocked my Athlon II X3 440. I don't know what it is exactly but unlocking the cores stops the sensor from picking up the core temps.

While attempting to run a game in bootcamp on a rMBP, the CPU gets hotter until it throttles and the game stops working. Is this normal? A machine like this shouldn't have this problem. I haven't touched it and fans are maxed with CPU still at 90 degrees.

All right, here's what's going on. I have been trying ot run a very graphics intense game on my Macbook Pro with Retina Display through bootcamp on windows 7. When I start the game up, it runs beautifully.... for about ten minutes. Five minutes in, the fans start to whirl loudly. By ten minutes in, performance begins to degrade noticibly and the game starts to stutter. I live with the stuttering until it becomes completely unreasonable and I shut down the game. When I come back to my computer several hours later, the process repeats.
Here is what I believe is happening. When I start the game, the CPU immediately begins to heat up, as CPUs do. Ten minutes in, the CPU has heated up past the safety limit and begins throttling itself back so as to protect itself. Over the course of the next little while, it continues to throttle itself until it finally doesn't have enough power to properly run the game at any reasonable speed, at which point, I get frustrated and quit. My concern is this. I understand that mobile rigs aren't necessarilly the most game friendly, however, this computer should be more than capable enough to handle some light gaming. (Mind you, I'm only playing ten minutes in when the game starts to lag.) Is this something I need to bring into Apple? Is this normal?
Thanks for your help!
Malaxtom

Did you download and install the Apple drivers onto the Win7 system when setting up BootCamp? Without them, Windows will have no way of getting the fans to do their stuff when things get hot.

HT3576 I only receive notifications for apps when i go on them and they are enabled in the notification centre. What do I do?

Right. My friend gave me her iPhone 4 running the latest iOS 6.1.3 and I have all apps turned on in the notification centre however I only get new notifications when I go on the app e.g. Kik, WhatsApp etc. what do I do? Also my FaceTime and iMessage don't appear to work and this might be related to the problem possibly

Do you have an active data connection?

Cpu and fans running at 100%

I've been working on this 20" iMac G5 for a couple weeks now and I'm stumped.
I've reset the smu, the nvram, wiped and put on a fresh install of 10.5, updated to 10.5.8 and still the computer is LOUD.
The fans run at a constant 100%, so I check the processor temp and it was 85c the instant the screen came on. So I proceeded to check the ventilation, took it all apart and all the air ways are clear, I checked, cleaned, and applied brand new thermal paste, put it all back together and still the instant the screen comes on the fans go to 100% and temp jumps to 85c
Then a student said "is it working hard?" Just to humor him I launched the activity monitor and to my surprise it was. The processor was running at 100% and the process that was doing it all is "top" running from the user 'root'.
I proceeded to type kill 321 (the pid) and the processor dropped to 10% and after about half an hour the temp was a normal 60c and the fans went quiet, but the instant I log out or reboot that 'top' process kicks back on and the machine starts over heating.
I've tried 10.4 and 10.5, wiped the HD about 5times and 'top' keeps running the processor off the deep end with every install.
I've tried permission repairs and hardware checks, even ran the full techtools deluxe scan.
I've tried finding others with this problem but it is understandably difficult to search for problems with 'top'.
It is no longer under warranty and no one is going to miss it if I just throw it out, but I don't want to give up on a 2.1Ghz machine for student use if that can be avoided.
I'm willing to try any ideas to get that process fixed, the only idea I have left is to replace the cmos battery, and prey to the computer gods, but I doubt that will do anything.

Hey there - same problm here w/ white flatscreen G5 (PPC).
Did you have any luck in solving your problem?

HT5188 Free VPP app - Cannot load VPP Codes into Configurator because app is Free. Sister company developed the app for us at no cost and we are installing on our devices. Will the app expire after a year without VPP codes? Devices will not have connec

This is strange Case!
We have been authorized to download 40 copies of a VPP app. The price tier is free. We download the app through itunes and load it into configurator. Because the App is free we are not given the option to load the codes which we rightfully own.
The devices we wish to configure will not have internet connectivity in the future and I need to know that the app on them will not expire!
If I load the app with configurator (unsupervised!) will the app expire in a year and be disabled? I cannot have that happen!
Please advise!
Best,
Nelson

I sent my ipad to a company for repair (over 6 weeks ago) and they are not returning my calls or emails. What should i do?

Hi,
I sent my ipad to a company for repair.
They posted it back and had not repaired it, they asked me to send it back so they could repair...again.
I have had a couple of emails saying it cant be fixed and they would return it to me, this has not happened.
Everytime i phone the company they take my number and never call me back.
The pad can no longer be tracked on find my ipad.
They have emailed me saying they dont have any information for me.
What can i do?

That would be a matter for local authorities - small claims court, a lawyer, whatever. You have to follow up and stay on them and get whoever you need to get involved in the matter that can provide help. Depending upon where you live (if in the U.S.) maybe even the Better Business Bureau - or any local watchdog group that helps in cases like this.
I don't know where you live, but in my town, I would contact the district court or magistrate and ask for his advice. There is nothing that anyone here can do foryou and Apple would be of no help either. This is not their responsibility.
