OS X :: What's Chewing Up Processor?
Apr 14, 2009
About once a week, my computers gets bogged down hard. When I look in Activity Monitor, the CPU Usage graph is hitting the ceiling, but a quick glance at the CPU column in the process table above shows it should only be using about 30%. My guess would be iAntiVirus is scanning in the background, but according to Activity Monitor, it's using less that 1% of the CPU. Does the process table in Activity Monitor not really show all the processes? How can I figure out what is chewing up the CPU?

I wanted to do some research on this processor, do you guys know what is the processor model code for the iMac's processor?
Is it a mobile processor or a desktop processor?
What is the difference between this one and this one?

I noticed recenly that everything on my mini has been running slower than usual. I opened up the activity monitor to find that cpu usage is very high, junping between about 50 and 100%. The culprit seams to be a process called "System Events". I wondered why this process was chewing so much cpu and slowing my system down, and what exacly it was doing. The only thing ive changed recently is added a few "actions" to folders using automator so that when i add files to the folders they are automatically added to itunes and put in a playlist. Could this be the problem?

I'm running Tiger (with the latest software updates) on my old 12" iBook and in the last week it has started a LOVELY behavior of chewing through the 1.5-2GB free on the hard drive after it has been up and running for 5-20 minutes. The only recourse I've found is a reboot. I think it's tied more to the browser than the OS, but I've tried using Firefox, Safari, and Opera with the same result.

Firefox is just chewing up memory on my new i7...only with 4 tabs open (forums and gmail). Then there is the launchd tearing up about 375 constantly. Window server is hovering around 175-200 as well.

I have a question as I am about to buy a MAC PRO. If I choose to go with single 2.8 quad will I be able to add another processor or the MB with MP will need to be updated aswell? I just don't have enough $$ for it all as the 8800GT is a must for me at this point.

I currently use a G5 PowerPC 2.5 Quad with 8Gb RAM. With the ever increasing size of digital images (my camera now takes 24Mp images), I find the initial browsing of my images increasingly slow. Also, non-Intel processors are becoming less supported by the latest software and I figured it's time to invest in a new setup. Just today, I sent back my iMac i7 (as a result of the well publicised screen issues) that was potentially to replace my G5. I have taken the decision to invest in a new Mac Pro and utilise my existing 30" cinema screen. The likelihood is that I will wait to see what the 2010 Pro shapes up like, but in preparation, can someone please tell me what is better for photoshop (I will be upgrading to CS5 once released), one big or two smaller processors?? For example, looking at the current offerings, which would give faster/better performance, a 2.93 quad core, or 2 x 2.26 quad cores, each with 8Gb RAM?

I'm definitely no computer expert, but with all these Mac Pros with all these cores, I'm not sure how to read their configurations. The single quad core is 2.8 GHz. But if you get an 8 core, you get 2.4GHz. And then there's the six core which is 3.33 GHz!! Which of those is faster and why? I don't want to spend $1000 more for more cores if it's actually a slower processor

I am getting an imac but am stuck as to which one. I would like to know from users experience if the 3.06 i3 processor is powerful enough and can easily run software such as photoshop and flash. Also i would like to know whether they run games ok and software such as steam, which is quite laggy on pc.

I have an early '08 Mac Pro that came with one E5462 2.8GHz Xeon processor. I would like to upgrade the processors as much as possible. As far as I can tell from my own research as well as the information on other threads in the forum, the best processors I can put in the machine are the Xeon X5482 3.2GHz chips. I found a pair of them on eBay, but the seller says the steppings are "E 0 steppings". The seller describes the chips as "Intel Xeon Quad Core X5482 E S"... which sounds like they were Engineering Samples... I'm okay with that, but what about the "E 0" steppings? Will they work in the Mac Pro?

These question my sound kind of silly, because I have not used a digital scanner in 20 years. Can I scan and edit a typed piece of paper onto a word processor?

Why do you think Apple did not use the I3 processor in the new Air? Cost? I think it uses less power and is faster the much older Core 2 duo. I have not been able to find any information on it.

I have a process on my iMac (core i7 quad, 16 GB Ram) thats called KRB5KDC. It uses 100 % of my processor, and 2,8GB Ram, All the time - Even just after i booted up. This makes the computer pretty useless as you can imagine.
After googling and mRoogling around i found out that the process belongs to Kerberos - some sort of network authentication protocol - i dont know anything about that, but it shouldnt use 100 % processor power.
Any help would be greatly appreciated, since applecare couldnt do anything but offer a hardware repair - strange solution for a software problem...

I'm in the market for a new MBP and, looking through the models, it's between the: 13" 2.4 GHz Core 2 Duo with 8gb of RAM 13" 2.66 GHz Core 2 Duo with 4gb of RAM I'll be using it for: Adobe apps (Flash, Photoshop, Dreamweaver, InDesign; often 2 of these at a time), videos (esp. streamed online), word processing, and general web browsing. I often have at least 1 of the mentioned Adobe applications, as well as a streaming video and 5-10 browser tabs open at once. So, which is better for my purposes, the 4gb more RAM but slower processor, or the faster processor with 4gb less RAM?

Anyone know if there exists a utility for 10.4 which replicates the "System Prefs.. Energy Saver.. Options.. Processor Performance" option but in a more accessible way? I tend to switch modes fairly often, so ideally I'd like a little menubar icon which I could click to toggle performance modes, or maybe a dock icon. No widgets please

I wish Apple would develop (buy or steal) a good word processor. How about just reengineering Pages to LOOK like MS Word? The familiarity would be a big selling point. I bought iwork... and Pages just baffles me how strange it is.

when doing high processor use tasks like copying 5 gb files or playing hl2 on steam the processor use always stays below 50% (istatpro)
1) why is this the case ?
2) if i could use more processor time would it improve performance of high use tasks?
3) if this is not normal behavior what could cause this ?

Can it be done? Is there a second socket on the uni-processor Mac Pro model which will allow for the addition of a second processor to the board, to give a dual-processor machine? For instance, with the 3.33GHz Mac Pro -- could you add another identical 3.33GHz quad-core processor to a second socket?

I see a great deal of debate between the quad i5 and i7 but nothing between the two i5's. I'm not super techy so I really can't tell what the benefits or disadvantages there are between the two. In fact, I didn't even notice that there are two different ones until I was poking around on apples site.
Specs:
3.6 i5 with 4mb lvl 3 cache and HT and TB
-or-
2.8 quad core i5 with 8mb of lvl 3 cache with TB but NO HT
*you can build identical iMacs both with the 5750 (5850m) and the 3.6 is only 50 bucs more.

I am thinking of buying a mac mini with these specs
1.66 GHz Intel Core Duo Processor
2GB 667 MHz DDR2 RAM
Intel GMA 950 Graphics
250GB Hard Disk Drive
4 USB Ports
DVI Connector
I am wondering if I could upgrade the processor to i5 and the HD to a 1TB because I plan to use it for basic movie editing and I am on a $600-$800 budget (the computer cost $250)
