I bought one of the new-gen iMacs last month--my first Mac! My computer will often start making a low-droning noise, and it sounds like a fan. I have iStat, and usually during this time it will say that my Optical Drive and CPU Fan are both running at around 4000rpm. This happens when there is very little CPU usage too. It's happening right now, and I only have firefox running.

I only started noticing my fan running a bit on the fast side this evening after installing the new Safari 4.0.5 update. I looked at iStat Menus for temp and CPU. And I was seeing about 190 degrees F for CPU temp with lid closed running ext display. Also there was a constant usage of the cpu (about 30% User and 20% System). There's not one particular process I can see in Activity Monitor that acting out of the ordinary and using a lot of CPU. Just stuff like coreservicesd, WindowServer, launchd that are shuffling around and using about 1-4% of CPU.I ran repair disk permissions and verify disk. Verify Disk found errors and said I need to repair my Macintosh HD, which I have now done successfully.

I checked system profiler but quite frankly wasn't sure of the designations.. does anyone have any experience with this camera, by the way? is USB 2.0 by definition "High Speed"?

View 2 Replies View RelatedI have a PowerBook G4 15" 1.33GHz that up until now ran flawlessly. Today I was watching a movie on it with some friends when it randomly shutdown. Since then, it no longer turns on. The battery is fully charged and there is no problem with my AC adapter. With just the battery, nothing happens when I press the power button. When the AC adapter is plugged in and I press the power button, the optical drive spins at full speed for a few minutes and then the PowerBook shuts itself down again. I have attempted reseting pram and pmu with no success. I think it could be a dead logic board but I'm not sure. Would it be worth the money to buy a new logic board or should I just part it out?
View 2 Replies View RelatedAt times my iMac (27" July 2011) starts making loud fan noise with mouse showing turning rainbow. The only way to stop is forced shutdown by pushing back button for a while. Yesterday I switched to widget screen and saw hard drive fan speed > 4000 rpm without CPU and temps by on the high side.

I found this article below when searching on iMac i7 info.We took delivery of the brand spankin' new 27" i7 iMac last week and connected it immediately to our Final Share SAN in about 5 minutes for video editing. Quick tests showed the SAN was connected and working fine.Then today I started really editing on it and I'm dropping frames every 10 to 30 seconds. Now it appears the ethernet controller that is in the new Mac cannot support the speeds necessary to edit video via the SAN. Our 2 year old iMacs can, but the brand spanking new, most powerful iMac cannot.I'm at a loss as to how Apple can improve every aspect of this machine, including the absolutely stunning 27" LED backlit display, but then cut back on something as simple as an Ethernet Controller that should be designed to work with today's equipment running high speed internet instead of stepping backwards to the speed of older model PowerMac machines.

My computer has been running incredibly slow lately. I think it has to do with the disk usage as every time it has to access the disk, it slows to a crawl. I've had a huge amount of beach balling, especially when loading a new App or a new page in Safari.
Here is a picture of the disk usage. Does this look normal? Does anyone know what the problem could be?
I was wondering if anyone had successfully installed and 2nd hard drive in their iMac?I have a 2 year old 2.8 24'' iMac and the performance just isn't cutting the mustard, it's all hard drive related and I already have a decent 1TB drive in there.I was thinking of perhaps swapping the optical drive with a second hard drive for RAID0, but not too sure if there will be space and was wondering if the optical drive is a standard SATA connector, or if there is some way I could run a SATA+power cables externally?
View 7 Replies View RelatedJust wondering if this is normal? Almost 30gb of VM in use? I'm encoding one of my DVDs and Handbrake is only using about 90mb of real memory while a bunch of background apps are using about 600-800mb of VM memory. Yesterday I encoded a DVD in like 20 minutes. I did a restart to refresh my memory but it's taken like over 2 hours of encoding and it's not done yet.
Attached is a picture of my Activity Monitor.
I've searched all over the internet but have yet to come across an answer. I love my Mac, but why is it that when I play a video in a web browser on my MacBook, (be it Flash, QuickTime, etc.) my CPU usage is anywhere from 60-80%, yet when I play the same video on a laptop running Windows, the CPU usage is always in the single digits?
I realize that video takes a toll on the CPU with integrated video cards, but it doesn't seem to have the same effect on Windows based laptops with integrated video cards. Is the CPU usage possibly just calculated differently, or is the Mac architecture somehow just really inefficient at this?
Whenever I start iChat on my new mini, it instantly spikes up the CPU usage and just sits there high. Activity Monitor says it's around 97%. I'm not doing anything in it; just starting the app gets it up there, and the only way to get it to go down again is to close the app. It doesn't seem to make a difference whether I'm online or off.
View 6 Replies View RelatedA few days ago I found that launchd was constantly using around 14% of my CPU (via iStat), which drastically lowered my battery life and caused my CPU to reach 75 degrees Celsius and higher. Initially I thought that SL just needed to do something, so I ignored it. But it has persisted for a few days now, so I decided to do something about it.
I checked the Console and nothing appeared to be repeating itself, so what I did was use MainMenu to perform a batch of system maintenance tasks, and then left my Mac on overnight to see what Console would report. Besides hourly instances of "kernel" running "iCalHelper" and "SubmitDiagInfo", there was nothing else.
However, launchd lowered its CPU usage to about 3%, but it is still constant and my CPU is still at a constant 40-50%. Activity Monitor says the following processes are (constantly) taking only 1-4% of the CPU:
coreservicesd
launchd
mds
WindowServer
disnoted
activitymonitord
...and others
The CPU is reported as 35% User and 20% System. But I am not running anything besides Activity Monitor.
My MBA (Ver A 1.6) just started getting the "sluggish" symptoms. Started noticing that my CPU gets stuck at 90~100% after about 30 min of use, since about a week ago. I keep restarting the computer and after about 30 min, my MBA becomes very sluggish and iStat shows both CPU bars all the way to about 100%.
When this happens, the activity monitor shows the kernel_task at 125~130. This is too high, right? If it is, what's causing this? I can't imagine that any of the programs that I regularly use will cause this.
Here's the screen shot of the activity monitor.
I've had my unibody Macbook since October. Recently I installed a few game apps including Sims 3. The problem is that when I try to play a game, it shows that my CPU usage is around the 100 range, the temperature is around 150 degrees, and the fan is around an average of 4000 rpm. It gets annoying cause you can hear the fan making a loud noise, I'm not sure if its my laptop or some other problem.
View 4 Replies View RelatedI've noticed that my macbook pro has been using a lot of RAM. I haven't really witnessed a slowdown on my computer b/c of any sort of shortage of RAM but I was just curious if this was typical (since this is my first mac). I have 4 GB of RAM and I often find myself with around 1-1.5 GB of free + inactive RAM. I had a linux system with 3 GB RAM before and it used between 1-1.8 GB of RAM and it seems like this system is using around 2.5-3 GB (active + wired). However, various OS X laptops in the past have functioned really well in the past with 2 GB and even 1 GB of RAM right? Is OS X just putting more processes in my RAM to speed up my system because more RAM is available OR does snow leopard just have high memory consumption?

CPU usage on one core runs to 100% only by scrolling fast in a window (finder, firefox, activity window). It happend without any system adjustment nor on any update or new software. Had the same issue months ago. Helped to went back to 10.7.2 and upraded again to 7.3 via combo update. System is after standby not usable, have to start system new as work around. Found same issue with other users on the web, but no solution.

I believe there might be something wrong with my MacBook Pro-It's a late 2008 one, mid configuration. Intel C2D 2.4 Ghz, 2 graphics card, 2GB RAM, ... (Using SL)
I usually find myself using up most of the RAM, with 96MB of RAM left right now, and sometimes when using Photoshop, up to 15MB. My CPU usage is quite high, with Chrome using 17% + other Chrome processes.
I'm only opening up 13 active tabs with 12 pinned and disabled tabs; Is the CPU usage too high?
I have white macbook c2duo 2GHz.After last iTunes update it still consumes about 60% of CPU whe running. If I say running i mean that it's not playing any music. Library Sharing is off. I was trying to find out something but i had no luck. Only I can say is that the same thing is occuring on my friend "Old" Macbook Pro (intel c2duo) but not on any iMac or Unibody Macbook i have seen.
View 2 Replies View RelatedThe HD crashed about 2 years ago, and since the replacement (TOSHIBA MK6034GSX 60GB) the CPU will go very hot 80+C and the fan going to 6200rpm if visiting some internet pages. Normally a problem if (when) the kids are playing free online games or visiting youtube or similar. Made a screenshot, notice CPU usage around 112%, smartfan showing 70C and 6200rpm. I have taken the mac physically apart and cleaned the cooling duct and applyed new thermal paste. Didn't help. It drives me crazy, I hate noisy computers.
View 10 Replies View RelatedI will be running MS Excel, preview, firefox, and activity monitor. All of a sudden my Activity monitor says that there is about % User of 50% and the fan will start running. I cannot find what program is making it run this high. I quit every program and it gets stuck on this until I restart the computer. I have done this about 3 times and it always comes back. None of the programs are registering high CPU usage. My last computer had an overheating problem where the fan was always on and that was part of the reason I switched to Macs - really hoping that issues doesn't follow me from Windows to Mac.
View 4 Replies View RelatedI bought one of these: [URL] and decided to do an experiment, now on standby (Laptop cover closed) it consumes 1.432 per night (8 hours). Laptop on standby, Cover Open but Display in Sleep mode for 8 hours costs 4.731 per day. So that means per month on standby at night, my Macbook costs 44.392. This can't be right? Because if it is, I might have to turn it off at night from now on.

At this moment, all I have is Firefox, Activity Monitor open and that's it, obviously there's system stuff going on as well. I took a pic and attached it.
Though is USED 1.25GB high, as it sounds real high to me. Is it too high, if so how can I lower it?
The Mac works fine.
I've been thinking to increase the RAM recently, and purchasing an extra 4 or 8 GBs

I just bought my first mac (2010 13 inch base model) and i was looking in Activity Monitor when i noticed that my free system memory is around 15-20mb. Is this normal?
