OS X :: Task Priority And Superfluous Applications?
Mar 20, 2010
I just tried to move some critical data from one drive to another and the operation froze. The folder showed up in the destination but then the copy wouldn't start. What was the problem? Apple apparently set its automatic reminder for the Software Update application to a higher priority than the user task. After a few seconds of being frozen, the folder disappeared from its destination and the Software Update window appeared.
Why is a background application more important than a file copy that was initiated by the user? What was so important that it had to interrupt my file copy? A Safari point update, something about Digital Camera RAW Compatibility for iPhoto and Aperture 3 (neither of which I use), and an iLife Support point update (which I also don't use). Is there a way to tell OS X that whatever I'm doing with copying or moving files should always have a higher priority than any background tasks?

Is there a way to set the priority of a certain process in OSX? Whenever i'm rendering something in Final Cut Pro or any other program, it slows down the whole system (duh), but whenever i'm doing something under windows (rendering 3D or whatever) I can turn down the the priority in the task manager (where would windows be without CTRL+ALT+DELETE) so the whole system doesent slow down to a crawl and I can contunue to do other things while the system is busy rendering. I know it will take a little longer to render depending on whatever else im doing, but i hate slowdowns so much (especially a slow dock).

There is this icon on my task bar that I can't seem to get rid of. I downloaded and installed an application to format an external drive, then when I wasn't happy with it, I deleted it. Unfortunately, when I deleted it, it didn't delete the icon it put in my task bar. I can click on it and get a menu and do a number of things. At the bottom of the menu I can choose "Disable DrivePulse". Nothing happens! I go to system preferences and look at my login items and it's not there! I find it in activity monitor, quit it from there, and it comes back a second later! I search my mac for Drive Pulse and Drive Genius 3 and I get no results! Can somebody help me disable this nuisance permanently? Is there a hidden file on my HD I have to delete?

Does anyone know of a task app that has the option to remain open and like pinned to the desktop? I've found some nice to-do apps that ive tried to use by my biggest problem is that if I dont see it all the time, I wont get it done- and I usually only open the app to add things to my "list" only to see things that I was supposed to have done!!
I realize that I could just leave the application open all the time, but that just doesn't seem to work for me, I like to see my background and I dont like having numerous windows open...

I have a downloaded folder with mixed types of files (.jpg and .ttf), I would like to separate them and put them in different folders, but there are hundreds of them and it's time consuming. Does anybody know how to do this?

I use iChat on my Mac and BeejiveIM on my iPhone - both with the same Jabber account. Also, I have Push Notifications turned on and I get all messages on my iPhone even if BeejiveIM is closed - you surely guessed it. What's so annoying? When I chat in iChat, all messages go to my iPhone as well and it "beeps" every second. How can I change the priority of iChat (or BeejiveIM - if possible) to make iPhone not getting messages when iChat's status is set to "Available"? Don't tell me to use Adium instead, 'cause I've used it and then switched to iChat.

I share my wireless internet with my 2 roommates free of charge. However, every now and then one of them will queue up a list of music to download (for example) and it bogs down my own connection considerably.
I'm looking for a way to prioritize my host computer so that the others don't overpower mine when I'm playing an online game or something that needs a steady connection. I tried looking in System Preferences>Network>Network Port Configurations, but that doesn't seem to be what I'm looking for.

i've been using programs that require some serious cpu power and i really need to know how to set any program to always run on high priority. I know theres a command you can run on terminal the "nice" and "renice" command but i only know how to set a program's priority once its already running so my question is how do you set a program so that it always runs on high priority from the start?

I have 2 Macs in the house, with a 3rd coming soon. I backup mine to an external hard drive using Time Machine, but neither of the others have a backup plan in place.
One user doesn't really need a robust backup solution, but the person getting a mac soon does.
I was thinking I could kill two birds with one stone if I got a Time Capsule. Now I've read all about how you can partition Time Capsule and stuff like that (and I'm technical enough that I could probably pull that off if I wanted to, but I don't think I do). What I haven't found out is what the Time Capsule does if two users have been syncing to it, and on the next backup it runs out of space.

I have a task called 'named' running and it's taking up 100% of a single core (swtiches cores periodically, but 100% when it does). Any idea what this is and whether I can kill it? It looks like it belongs to Internet Sharing.
Edit: I just turned IS off and it disappeared. Turned IS back on and it seems to have killed 'named'.

recently I've noticed that my task bar doesn't let me know what programs are running. For instance, normally when a program is open, there's a small white dot under the icon, meaning the program is open. Now that doesn't appear anymore. Can anyone explain how I can turn this option back on? I might have inadvertently shut it off somehow.

I have a new Mac Pro (standard 2.8 configuration with 3 X 250GB in software RAID0) at my cable station at college. I was expecting this thing to be a real screamer, but I find myself a bit disappointed. Don't get me wrong, it's still quite fast. But for CPU-intensive task in Final Cut Studio, I find it to be slower than it should be. For example, compressing a 6 GB DV file for an iPhone is taking 32 minutes. CPU usage is only around 30% per core. I've never been able to drive CPU usage above this level in any task (Handbrake, Final Cut rendering, etc.) I know that not all software is able to fully use all of the cores, but this doesn't make sense to me. Is this normal performance? Or could something wrong with the Mac Pro?

Every day NASA puts up an "Image of the Day" Sometimes it is a really cool nightscape, sometimes it is great hubble photography, etc... I've been opening up the page every day and right clicking on the new image and saving it to a folder. Is there a way to automate this?
I'd love for my computer to automatically go to the page with the new image on it and save it to a folder. Sometimes I jsut don't have the time to get over to the page, or I jsut simply forget. Is there a way to automate this process?

Is there any specific reason Kernel_Task seems to think he owns the place? What gives? It's like I turn my MacBook on and he's all like "oh hai! Ize just a system task! 50mb of memory? That's cool that's cool" Then only 2 hours later he's all like "Nah man, I just needed some more room see, it's like 120mb ain't dat much, k?"
I know that OS X handles ram real good and all, by freeing memory when it's required for higher-priority tasks, but I also know that it takes a bit more time to clear that memory AND re-allocate it...
So, is this a memory leak? And while I'm at it what about iChat Agent and Colloquy that are battling out to be RAM champ?
OH, and I haz 2gb installed at the moment.

Mac OSX 10.5.6When I have several applications running and one finishes a task it automatically changes to that space without asking. This is very annoying when I am in the middle of something in another application in another space. Is it possible to just get the icon to bounce instead of changing spaces like it did before using spaces.

I've been recently realizing that every time i use safari or socialite for a few mins I get a lot of 'beach ball' time. The application would show in red (not responding) in activity monitor and kernel_task would have over 1,900 threads, that will decrease slowly after I force quit the applications.

My computer keeps freezing and applications keep shutting down unexpectantly. So when I went into the activity monitor I saw that Kernal_task and inkjet1 seem to be taking up the most CPU, threads, and memory. What are they? How can I make my computer more efficient? Are these processess causing my computer to be so slow and freezy?

I have been experiencing the fan running at high rpm and the computer completely slowing down when there is slight pressure applied to the bottom of my macbook pro. I went on Activity Monitor and it shows kernel_task running at over 100% cpu usage. I have already tried resetting PRAM and SMC but those did not work.

I was working on my Mac but is coming very slow sometimes so I found the problem is the kernel task.
Lex I already use the Clean My Mac and since the first time I delete a lot of things I don't even remember how many. Should I format my drive?
About the iCleanMemory so the system will clear the RAM by it self or should I do something different or use another program?

I just bought my first 27 inch IMac a few weeks ago, I am a apple convert, today my mail will not close, the close mail tab is greyed out in to top task bar, and I tried to right click on the app and close that way but no go. Is there yet a third way to shut down mail that I am not aware of as I cannot turn off the IMac until mail is closed, miss the force shutdown tab in pcs.

The kernel task is taking up too much ram on my iMac is there a clear solution to resolving the issue or do i need to do a clean install?
Bootup is slow, applications open slowly and sometime hang.

I have a workflow that opens a list of webpages into tabs. It worked beautifully on Mavericks. After upgrading to Yosemite, I get the following error for most pages in the list, though some do seem to work: You can’t open the application “Safari” because it is not responding.
It seems that automator is submitting page calls faster than Safari can handle them, but I see no option to add a delay on the display of pages.
The same error occurs when "Google Chrome" or "Firefox" is set as the default browser, which leads me to believe it is an issue with automator or the display webpages task, not safari.

I have a late 2008 macbook unibody. The computer won't go into sleep mode with the lid closed or if I hit the power button. i have to manually do it with the apple icon in the top of the screen.
The ambient light that blinks while in sleep doesn't light up when I do this either. Its been like this ever since Lion, Mountain Lion and now Mavericks. I've done a clean install of Maverick on a brand new HDD. No change.
I have modified the computer since I've owned it. Upgraded from the OEM 2GB of memory to 4GB which is the max for my model. It didn't come with the illuminated keyboard so I bought the backlit one and installed. I also had to swap the motherboard to do this since my original did not have the backlight connector.
Note the old motherboard also had the same problem with the computer not going into sleep. So I don't believe its a hardware issue. (yes I plugged everything in and seated everything in a appropriate manner, I build custom PC's for friends all the time so what to do and what not to do).
I have checked my sharing preferences and they're all unchecked as this is a fresh install of mavericks. Everything else is all set to system defaults.
