MacBook Air :: Getting Core Shutdown - Any Way To Confirm?
Jun 21, 2008
I think I am getting the well publicized core shutdown with my MBA but I can't be sure. I will be doing a task and things like expose will be as smooth as can be but then all of a sudden it slows to a complete halt, everything lags, expose is jerky, cmd+tab takes ages to switch application and keystrokes such as typing take seconds to appear. For a good 5+ mins the computer becomes totally useless. Is this what a core shutdown does to the computer? Is there an application I can use to monitor how many cores are running? I looked in the activity monitor but couldn't find information about how many cores are running. I have used smc control to monitor my cpu temp and I sometimes turn the exhaust up to max rpm before I watch a video or do something that has been causing the core shutdown (if thats what it is) in an attempt to try and keep the cpu cooler.
I have read about coolbook but I don't fancy paying for an application to stop a fault that shouldn't be happening. Are Apple fixing these faults? Is this a problem with ALL MacBook Airs? I ask this because there seem to be two groups of people. People that don't experience this (or say they don't, maybe don't want to admit a fault with there new shiny toy?) and people who have had 3-4 machines all with the same problem. I would love to know if this is indeed a core shutdown fault and if Apple replace it for me as it is becoming increasingly frustrating and not acceptable for a $1200 computer. Would also like to hear from people that have had the core shutdown fault fixed or replaced from Apple and if it has fixed the problem, or if it still exists.
When "Confirming Names" in the "XXXXX may also be in the photos below" section of Faces, is it possible to change or choose a name other than the Face you are within? Is there an option to do this - I cannot find it?
For example, I have a Face named "Christine" with numerous photos of Christine already confirmed. I also have numerous photos shown in the section "Christine may also be in the photos below".
I have a MBA, and I do notice, more often than I had expected, that I'm experiencing core shutdown. I do agree with a previous post that it could, at least partially, be related to the video card/driver. If I decide to run a YouTube video while having Outlook open in VMWare Fusion, I'll usually shutdown a core. Other combinations of applications can do it too, but this combo is almost guaranteed.
My question is: Is there a time where core shutdown is good, for example, to preserve the integrity of the hardware? I don't want to go into the Genius bar complaining if all they're going to say is "Well look what you're running! Of course it'll shutdown!"
I was thinking of getting a refurbed MacBook Air and as I had one before and had to return it because the logic board was fried, I was wondering if Apple has fixed these issues? Also, being a refurb would they definitely make sure its not having those heat/core shutdown issues?
It's the last question before I buy the MBA. I have a program that can run under Win or MAC. That's a Picture convert and compile program work with my project. This program needs 100% CPU to and last 15 minutes to work under my old Pemtium M 1.6Ghz notebook. Usually I do my job use my notebook in home or my desktop PC in office. But occasionally I need to do some compile outside the office.
So I really need to know whether the MBA will definitely shutdown one core when the CPU usage is 100% and last 15 minutes? Or maybe you can tell me if the MBA will shutdown when rendering a project in Mayar or 3D Max last 15 minutes. It's important to me before I buy the MBA. I just need a light notebook and I can do some hard job occasionally, but reliable. I like a Fujisu S6510 too, but it is too expensive and heaver than MBA.
I'm trying to confirm that the MacBook 3,1 takes up to 6mb of ram. Which means to max out, I can use a 4gb module, and a 2bg module. Its a little confusing, because I found this info into on 2 memory sites, but the apple site does not seem to indicate this usage. I always thought it needed to be in equal pairs.
I bought AppleCare for my macbook from ebay (in an original and sealed box). I entered my code on Thursday and my status is still "in progress". Isn't this crap automated by Apple? What is the processing computer waiting for?
I see the numbers of everything from Core 2 Duo, to the slightly faster and cooler Core i3, to the supposedly faster core i5s and i7s. The benchmarks go up accordingly, but I found this does not always equate in a faster experience on most tasks.
Here's my experience so far on processor upgrade:
In one computer trade school re-certification class I am in, we are working with Windows Server 2003 on a Quad Xeon platform and it's incredibly slow.
But in a previous class we had the previous generation server edition on older Xeons, and while not fast, it was much better. On paper the newer multi-core Xeons should have made a difference, but could 2003 server software be that much more bloated than the previous Windows server edition that it would stall like that and make us wish we had the older setup?
I am going to try out the Adobe CS lab and put the new high end Dells to the test there and see if they work better than when we had an older CS version on older Xeon equipped Dells.
I don't know if this is something to do with Dell, or if Apple's increasing processor bumps/generations are going to similarly not make a difference in the speed things appear to go at, whether it's Adobe stuff, server stuff, or anything else that needs power.
I know somebody who plans on a Core 2 Duo, i5 or i7 MBP and I was wondering if the higher end processor is worth it in that case (iMovie being the main program of use).
There's a lot of people wondering if the 13" MBPs would have been a lot better with a Core i3 processor, but everything has been just hangups over perceived old vs. new technology, and really the only thing the Core i3 adds is Hyper-Threading, but it doesn't have Turbo Boost, which helps the Core i5/i7s tremendously. Let's compare using Geekbench since it is cross-platform and one of the few available sources of info...
Core 2 Duo P8600 2.4GHz (~3362)

vs.
Core i3 330m 2.13GHz (~3472)
[URL]
Core 2 Duo P8800 2.66GHz (~3700)
[URL]
vs.
Core i3 350m 2.26GHz (~3680)
[URL]
As you can see in both cases, the difference is pretty minimal indeed, and in single threaded applications, the C2D will easily outdo the Core i3 which lacks Turbo Boost and runs at lower clock rates.
And you get a 320M instead of Intel HD graphics with the new 13".
The Geekbench results from the old 15/17" to the new 15/17" are quite an order of magnitude better.
So unless people are expecting Core i5 processors in the 13", sticking to the C2D was actually a good decision, and given the differences between 2.4 and 2.53 isn't so large, one is far better buying the base 13" and then putting the money saved towards a good 7.2k HDD or SSD.
Note - I took averages of the 32-bit numbers and added them.
Note 2 - The C2D Pxxxx are 25W TDP processors, which are more efficient than the Core i3 which are 35W TDP processors. Less heat, better battery life from C2Ds.
I've been debating whether or not to upgrade my 3 year old 15" Macbook Pro that has a 2.2Ghz Core 2 Duo (Santa Rosa) to the new 13" 2.4Ghz Macbook Pro. FYI... My current system also has 4GB of RAM. Since both systems are Core 2 Duo, what kind of speed bump am I going to see? Would this be a substantial upgrade?
I'm buying a new MacBookPro but can't decide, due to lack of knowledge, wich one to choose and if there's a noticeble difference between,  15.4" MacBook Pro Notebook Computer 2.2GHz Intel Core i7 Quad-Core4GB of DDR3 RAM500GB 5400rpm Hard DriveAMD Radeon HD 6750M 512MB Graphics15.4" LED-Backlit Glossy Display1400 x 900 Native ResolutionSlot-Loading SuperDrive802.11a/b/g/n Wi-Fi, Bluetooth 2.1+EDRFaceTime HD Camera, Built-in MicrophoneMac OS X 10.7 Lion (64-bit)Â

Besides the screen size, one would be considerable faster?

The ivy bridge processors are coming out soon (or may already be out). I have heard that macbook pro 13" models might be able to use the new processers due to their lower energy useage. I presume that I will be able to take my mac to an apple store and have it installed. Is this information true?

Although i'm hardly impressed by the prices and specs of these 'new' machines I need one so I'm buying!
Just need to know before I make the plunge. Is the i7 variant with the extra GPU ram really worth it? I would use the extra power in my work but I honestly need to know if I'd notice any difference as for a few seconds less waiting it would hardly justify the price.
Since a few weeks ago, I have not been able to purchase anymore apps because of a somewhat PATHETIC bug. Â
When the system wants to confirm my info it get stuck with a very stupid problem, it tells me to fix the STATE I live in by choosing a 2 word option from the list or using numbers, well, It is absolutely correct from the start, and the system keeps telling me to fix the info of the state I live in, what the heck is going on? It's 100% correct! What can i do? BTW, I have a brazilian account, the bug refers to the brazilian address..Â
My iMac 27 late 2010 does not shut down when shut down in the normal way. I have to shut down with the push button. I have tried disconnecting all the usb connected hardware still no use. Can any body help.I have OS Lion 10.7.3?
Literally just got shiny new miniMac Server with the dual 70GB internakky hard drives/disks with OS X 10.7.$ LION pre-installed. What a nice machine in a super cool box Seemed to bootup and run fine!Now my issue (there will be more for this MAC newbie):How to setup AND more importantly (item B below) CONFIRM that a RAID MIRROR is working? Want nothing fancier than 2-nd drive is exact duplicate of 1-st drive at all times. That is, an 'active and full up-to -the second" backup of the main 1-st drive.I have done nothing to 1-st drive as it came from APPLE.When I try to setup RAID set using DISK Utility, I get message about system(1-st drive) can't be used in a RAID or such.
yet I can add 2-nd drive to what I tink is a RAID set and then 'Enable' it.It seems to add another entry to thr left-side of drves list panel but not sure that 1-st and 2-nd drives are BOTH in the new "RAID SET' or that the set just consists of the "single" 2-nd disk? B. I don't think that 1-st drive data is actually being duplicated to 2-nd drive.For instance, how do I know that it was 'caught up' to match 1-st drive AND then is [code]

My system has randomly shut down twice now in the last two days. Dual G5 2.3. I checked the console log, which I know very little about, and it said this:
localhost kernel[0]: ApplePMU::PMU forced shutdown, cause = -122
Two questions-
what's the -122 code mean?
Do you think resetting the PMU would be the solution to this?
I wanted to know if I can replace the upper case of a Core Duo white macbook with that of a Core 2 Duo black macbook? The white one has the distinctive yellowing of the rev A macbooks, so i'd like to make it better whilst making a black/white frankenMac.
I recently got a new MacBook Pro, and I successfully transferred all of my information onto my new computer from my old MacBook. I also bought a new external hard drive. I used Time Machine to back it all up. It says that it transferred everything, but all I can see are the Applications. I want to be sure that I have it backed up in two places before I erase my old hard drive and sell my old computer.
i add links cmd+N than i past links cmd+V and than i want to confirm/add this link to my download queue with shortcut so i dont need to take my hands away from keyboard, grab a mouse and than click it. the add button seems to be highlighted but when i press enter/return it does not add links. the only way i have found so far is to click it with mouse.
Just curious as to how much of an improvement in performance I would see upgrading my system as it states above, since my 2006 machine is 3 years old and getting close to the end of my apple care, figured I would trade it in and upgrade.
I am looking to purchase my first Macbook Pro. I am having a difficult time deciding between a $1749 17" from Amazon that is the older 2.8Ghz Core 2 Duo and the $2298 17" (w/ student discount and tax... have to include tax) from Apple that is the newest model. The price difference is $549.
Some things I'm curious about:
1. Intel HD card? Does it really cause that much lag? How is it compared to the nVidia 9400m? I don't mean benchmarks, I mean real life performance.
2. Battery life? Is the battery life in the newest model much better than previous gen?
3. Heat? Is there a difference in heat production between them?
I don't care about gaming, so the 512 300m vs. 512 9600m is no concern.
Does the newest 17" justify the $549 price difference? Are there any other things that I should know between the two?
Has anyone that know if it's possible to upgrade MacPro Nehalem 2.26 to 2.66 Ghz Westmare with the following processors : Intel Hexa Core Xeon? Processor X5650 12M Cache, 2.66 GHz, 6.40 GT/s Intel? QPI part #:BX80614X5650 ? Could you help me telling if it?s possible to upgrading MacPro Nehalem octa core 2.26 Ghz to Mac Pro Westmare hexa core 2.66 Ghz ?
