How to use only one core for Macbook Pro?

I know that Macbook Pro is a dual-core CPU Macbook. I know I can do this by using battery only. But are there any ways that I can turn off one core in the system while keep the power adapter plugged in? Thank you!

Navigate to /Library/Application Support/HWPrefs and launch the CPUPalette program.
(If you don’t find it there, insert your Leopard install disc, click on Optional Installs, select Packages, and double-click on CHUD.pkg; that will install CPUPalette.)
It will display two graphs showing how busy your CPU’s cores are, and let you disable one or more of them. Click on the oblong button in the upper right corner to reveal a settings panel where you can adjust transparency, sample interval and history, and chart format.

Does logic use only one core fore bouncing?

When I bounce a project the CPU activity shows only one core working at full level. The other seems to sleep? Can you confirm that?
Thanks Eddie

Welcome to the Apple community.
iTunes and iCloud and different accounts, you will need to delete both accounts from your device before adding the new details in their place.
For iCloud go to settings > iCloud, scroll down and hit the delete button. You can then sign back in using your correct details. For iTunes go to settings >store, tap your account ID and then sign out, you can then sign back in using your correct Apple ID.

Second mac in cluster uses only one core

Hello all. For some reason the second computer in my render farm is using only one core out of eight.
I'm using 2 Mac Pros linked together directly via giga ethernet wire. Mac one is a Quad Core 3ghz. Mac two is a Octo Core 2009 model. Both computers have the same version of FCS3 with different serial numbers.
In the Qmaster preferance pane: Mac one is set to "Quickcluster with services" with the check boxes for Share and Managed next to "Distributed processing for Compressor" checked. 4 instances selected and "Include unmanaged services from other computers" checked. Mac two is set to "Services only" with check box for Share next to "Distributed processing for Compressor" checked. 8 instances selected and "Include unmanaged services from other computers" checked.
I hit submit in Compressor, select the name of the cluster from Mac one, then in the Batch Monitor I see the video divied into 10 sections with Mac one handling 4 and Mac two handling one. On Mac two I see that the cores aren't fired up 100%, more like 30% on average.
I did a test earlier with a dual core mbp, and again only one core. How do I get my Octo core to use all 8 cores?

Solved the problem. The solution was simple, but somehow went under my radar. On Mac two in the Qmaster preferance pane next to the "Options for selected service" button, the selected service was set to off.
Duh

Motion 5 using only one core

Why is motion 5 using only one core during heavy renders, even when all other apps are closed?
Version 5.0.3

coz it uses the GPU to do all the graphics stuff. The cores are only used to process project data.

Can I use only one computer for driver development?

Hi! I'm newbie in driver development and now is first day when I make the acquaintance of driver development. There is the next phrase in MSDN in
https://msdn.microsoft.com/en-us/library/windows/hardware/hh706187(v=vs.85).aspx
: "For developing, debugging, and installing a kernel-mode driver, you need two computers". But I unfortunately have only one computer and I have to develop the USB Kernel Mode driver as technical assignment for admission to the job.
My computer is under Windows 7 OS and already has standard USB driver. I have Visual Studio 2013 Ultimate and WDK 8.1 Update on my computer. Can I use only one computer for driver development and debugging or not?

no, not really, you need two. you can use a VM as the machine under test though.

Mathematica 5.2.2 uses only one core

Using Activity Monitor, I have seen that Mathematica 5.2.2 uses only the second core, even if Wolfram says that it supports multi-core calculations.
So, firstly, I use only half of the power of my MBP C2D and secondly this could be dangerous for the processor because I use Mathematica all the day for work and this asymmetric use of the processor could damage it.
Do somebody know how to use both the cores?

This is a Mathematica problem. Contact their technical support. The Apple Discussions are limited to assistance with Apple products. We can't fix a problem with Mathematica software.
Furthermore, there's no reason why the use of one core will damage your processor.

if they aren't available for download from the app store or the games website, you would need to purchase the boxed version and make sure it is compatible with mac and that your mac meets the games technical requirements.

How do I program a NI 6602 card to send trigger pulses, one at each output port, triggered by an input trigger signal, using only one counter for each output port?

Hello,
I have managed to program a NI 6602 card in LabView to send pulses on three different output ports, one pulse on each output port (with individually chosen delays) for each input trigger pulse coming on a separate input port. It is the DAQmx Create Channel (CO-Pulse Generation-Time)-VI that I have used for this, see attached code. However, this VI controls both pulse delay and pulse width, and therefore uses two counters for each output port (although you only specify one counter in the VI input signals), as I understand.
In my application though, I only need to have the delay chosen, the pulse width can be arbitrarily short, and thus I should only need one counter for each output port. How do I accomplish to program this in LabView?
Best regards,
Claes

Well you're welcome to do that--it will work just fine as long as you are configuring a start trigger.
<rant>
However, personally I really don't like putting multiple counter outputs in the same task. I have seen so many people assume that the counter outputs would be synchronized due to having them in the same task when this is not the case (you need to configure a start trigger in order to synchronize the counter outputs even if they are in the same task). This is the only case I can think of where multiple channels in a DAQmx task are not automatically synchronized.
As an example:
Running this on my PCIe X Series gives a measured 2 edge separation of 1 ms + {7.78 us - 10.11 us}. This would likely be much worse on a bus with more latency (e.g. USB).
The resulting output is close enough to what you might expect that it might go unnoticed, but really these counter outputs are not synchronized and it would be easy to glance at the code and not even think twice about it. For the small amount of extra work on my end to create a separate task for each counter, it really clears up some ambiguity about what the counters are actually doing. For me it's worth it.
So again, for your case there really isn't a problem with having the counters in the same task since you are using an external start trigger anyway. I have just gotten in the habit of avoiding doing this.

How to use only one event case at a time??

Using LabVIEW, using the event structure is it possible to have only one event case execute at a time. For example, having event case controlled by keyboard, and the other event case controlled by mouse (clicking buttons) and only one being able to execute, not simultaneously. I was considering using a switch of some sort, but each case does not have a "stop if true/false" so I am open to a new method or work around. I attached code. I do not want output to be able to be sent from the keyboard case and mouse case at the same time.
Thanks,
Andrew

Ah, OK. all you need is to keep state in a shift register that ensures that all "key down/mouse down" events are discarded after each key down/mounse down event until a key up or mouse up (resp.) has occured.
Overall, you code is still way to complicated for this simple task. For example, you could eliminate all these "select" primitives and place the approriate diagram constant inside the respective case. On the other hand it is too simplistic, because you would think that certain key combinations should be allowed concurrently (e.g. up and left).
What does the receiver actually do with the codes? Do you have any documentation for this device?

Configuring fbdev to use only one tty for display.

Hi Friends. I use the following command for playing videos at tty(I don't use X due to very low specs of my old pc):
mplayer -vo fbdev2 -fs FILE
but the problem is that the linux framebuffer displays the video on all the tty's. so, how can i confine it to display only on the tty from which the above command is run ? Please Help!!

Actually that's how you must do it (keeping only 1 servlet as a controller). That's MVC Architecture.
Use a hidden variable in each of your JSPs. In your servlet, use a switch which will do the action depending on the value of your hidden variable. Then in the servlet you can use include, forward and sendRedirect accordingly.

New Mobile Account works on only one of two MacBook Pros

I am setting up mobile accounts for my small company. I have two accounts, two MacBook Pros and one MacMini with OS X Snow Leopard Server. One mobile account works fine on both of my portables and the other one only works on one of the portables.
On the portable that does not allow the creation of the mobile account I get a message at logon stating "Unable to create mobile account... There was a problem creating your mobile account".
The /var/log/secure.log on the MacBook Pro has these entries:
loginwindow[46]: Login Window - Returned from Security Agent
loginwindow[46]: AuthorizationRef returned an error (-60006), with username = randy.kahle
loginwindow[46]: This indicates that a SecurityAgent plugin has returned something other than errAuthorizationDenied (usually cancelled) after the auth record is set up.
All of the entries in secure.log indicate that authentication was fine and the home directory mounts occurred correctly.
Both the OS X 10.6.4 server and client have the latest software updates.

Yup, that did the trick. The other Macbook had sharing on.
Thanks

Use iMac as monitor for MacBook Pro

I have a 15" MacBook Pro and a 21" iMac, both early 2008. I'd like to use the iMac as a second monitor for the MacBook. Is this possible?

I believe what you're looking for is Target Display Mode, but I don't know that a 2008 iMac supports this feature.
