Core Duo compared to development kits

Do you think that the Core Duo's are faster than the development kits? I know there are a lot of other differences but are two processors running at 2.0 Ghz faster than one running at 3.6? I am all for having a dual processor iMac, just wondering if it was necessary.
Thanks,
"D"

It should be faster with any apps which have more than one thread (i.e. are optimized for multi-core/multi-processor systems). As for single-threaded apps, the Core Duo should perform like a 2.0 Ghz Pentium M, which is probably as fast or faster than a 3.0 Ghz Pentium 4 in almost every situation.
Note that the Pentium 4 660 processors shipping with Developer Transition Kits support Intel EM64T technology (64-bit on x86), whereas the Intel Core Duo does not ...

Core Duo Processor

How does the power of a Core Duo Processor compare to that of a single processor? For example, is a 2 GHz Core Duo Processor as powerful as a 4 GHz Core Processor?

On average, what is the speed of a Core Duo compared to a single Core Processor?
The thing is, to say anything at all would be dependent on software. Whether it were multi-threaded, whether it depends on RAM bandwidth, hard drive performance etc etc.
For instance, my Mac Pro is generally faster than my MBP is a serious way although if you were to compare CD rip times there's not a lot of difference. This is mostly becuase the optical drive is now the bottleneck rather than the data processing and encoding. If you were to make comparison based on this and tasks like this then you'd say the MP isn't worth it.
For what use are you really wanting to compare?
The real answer ranges from not a lot, if any, difference to quite a substantial difference.

Java Development issue/differences between Core Duo and Core 2 Duo (??)

Hi Everyone,
I am a Java developer that uses my 17" MBP Core Duo for all of my development. Lately, I've been trying to use both the Glassfish Application Server V2 (from Sun) and Maven 2.09 from the Apache project. I have configured identical scenarios on my MBP Core Duo and on a 15" MBP Core 2 Duo.
The scenario involves compiling and running some webservices (at least on the Core 2 Duo) in a local development environment. Both machines use the default JDK 1.5.0_13 installed on the machine.
On the 17" Core Duo, issuing a "mvn install" command produces the following error:

I have installed the same software versions and have the same configuration on a Windows desktop running XP SP2 and get the same successful result.
Is this an issue between the Core Duo and Core 2 Duo? I can't see that it is since I don't believe the hardware influences the software to that degree. However, I am at a loss for what is causing the issue and the Apache Maven list insists that there are developers that are using Maven successfully on OS X.
I really need to get past this issue, but I am at a loss. Please help.
Thanks,

Have you repaired permissions? (/Applications/Utilities/Disk Utility.app)
Are you sure you're using JDK 5? (Applications/Utilities/Java/Java Preferences.app or output of $ javac -version)

Have I made a mistake buying an Core Duo?

Hi
Am I doomed, Have I commited a crime, Am I going to be dissapointed? I am getting worried here, as I sit glaring onto the screen of my new Intel Core Duo 20", and staring even harder at the lovely black box of my Motion 2 Software which I can't do anything with!!
Hope some of you have some thoughts here, I am a new mac user. Previously I have been a keen amateur in video work, using premiere on a windows pc.
I have decicded to make the leap to doing video on a mac and to learn FCS
I have just bought my first Mac, (a intel core duo 20" standard set up). I also (a week before getting the iMac) bought Motion 2. I didn't have the choice to buy a powermac, as they are way over my budget, especially as I would have to buy a separate screen.
So my budget conscious plan was to buy Motion 2 (which i have), Buy a mac (which I have), order final cut universal upgrade, (which means I end up getting FC Studio for £300 instead of £900) and whilst waiting for studio to ship I could begin learning motion.
Alas, as I have now found out, Motion doesn't run on my intel iMac (it doesn't even start up). Through this forum I have now found out why - although to be honest the tech support guy at apple i rang had no idea why it wouldn't , and to be quite frank he should of know know shouldn't he, as he works for mac for petes sake!!
Anyway, heres my question. I am now worried that even when I get my universal copy of FCS I am going to be dissapointed.
Is my intel iMac going to struggle to run the FCS apps? (especially motion)?
Is the graphics card (an ATI X1600) up to the job? (i had the basic 128mb)?
What kind of ram am I going to need? - the max I can have is 2gb?
It may be the case I am stuck with what I have got, as its now a week old, and don't think I am allowed to return, just because I may have made the wrong buying decision.
I really regret not having the 256mb video card version, and I should have researched more. But I bought on impulse from PC World, and the bloke didn't have a clue, and he never even mentioned the other option.
I am now wondering if I shoud have just bought a refurbed iMac (not intel) or even a second hand powermac.
Anyway - some opinions from you guys on whether I have a system that is going to be able to run Motion and FCS Universal, or whether I am in for a rocky road ahead would be good at this stage?
Advance thanks

Welcome to the family. While we sympathize with your situation, we're seeing a lot of it these days. We're mostly sorry you Intel buyers didn't spend more time doing better research before spending all your money.
Buy the universal update package, you have no choice, but look carefully at the specs on the iMac's graphics card and compare them against the requirements for Motion. I don't use an iMac but the card may not be up to the task and I don't know if it can upgraded; you may never be happy with the iMac's performance.
If Motion is crucial to your plans to make a living in video and motion graphics creation, you have no choice but to buy a properly equipped machine. Think of it like gaming on a PC. If you want to compete in the coolest games, you buy a PC that is hacked for gaming. If you want to do Motion, you must buy a Macintosh made for the task.
The first level of Apple support is twits reading scripts. All they know is how to tell PC users to install iTunes. Do not expect to get any useful advice from Apple on the phone unless you are buying the pro support. Stop here first. we're free and we care.

I have a MacBook Pro with Intel Core Duo and Snow Leopard 10.6.8. Want to upgrade to Lion to take advantage of icloud. Is there anything I can do without getting a new MacPro?

I have a MacBook Pro with Intel Core Duo and Snow Leopard 10.6.8. Would like to upgrade to Lion but it requires a minimum of Intel Core 2 Duo. Can I get what I need or do I have to buy new MacBok Pro?

I also have a core duo MBP with Snow Leopard and it runs perfectly. There are very few things it cannot do as compared to the faster, newer MBPs, but that is attributable to the CPU, not the OS. There are some who view Lion as downgrade rather than as an improvement. If there are important applications that reqire a fast CPU or Lion features that you find essential, by all means get a new MBP.
I have an aphorism: Obsolescence is more often a perception rather than a reality. Besides the silver keys look much classier than the black ones.
Ciao.

G4 iMac migrates to Intel Core Duo

I just migrated the contents of my 17” G4 iMac to a 20” Core Duo. The only piece of software that wouldn’t run on the new Mac was Nikon Capture 4.4.1; upon launching, it told me that it was missing necessary files. I reloaded the software from my original 4.0 discs. This time the error message said to click to go to PACE and run the installer, which I did. The installer claimed to run successfully, but NC4 still claimed to be missing files. At this point I went to the NikonUSA website and downloaded the NC4.2 updater. After running this and rebooting, NC4 ran just fine. I finally updated it back to V4.4.1, which also works properly.
Rosetta notwithstanding, compared to running NC4 on the G4, it’s much faster. Opening a D200 RAW file on the Core Duo is about as fast as opening a D2h file on the G4--not instantaneous, but reasonable at around 7 seconds. Same goes for edit files.
With 2 gigs of RAM on the Core Duo, NC doesn’t suck up all the memory, as it did on the 1 gig G4. No “page outs” when working on several RAW files at a time. This is much better performance than I had been expecting from it.
PSE3 work reasonably well, too. Faster than on the G4, at least.
While I was trying to get NC4 to work again, I did play around with iPhoto6. It seems very fast and has some interesting features, so I’ll probably start using it too.
All the included iLife6 programs seem to work well, and much faster than on the G4.
I had no problems with any peripherals except a very old USB CameraMate Compact Flash card reader, for which the OS X driver appears to no longer function. A no-name card reader I got for free from OMax works fine, though. So does my Epson 1650 flatbed ( I use PSE3 to access it), a QPS external firewire drive and an Epson 1270 printer. No problems with Wi-Fi or ethernet,either. When I plugged the ethernet cable fron the Core Duo into my Airport Extreme base, the computer automatically switched its settings from Airport to ethernet--neat!
This is the seventh Mac I’ve owned and the easiest migration so far. The improvements in performance and in the quality of the display greatly exceed my expectations.

my Macbook Pro with 2.16GHz Intel Core Duo (Mac OS X v10.4 Tiger) can convert to Lion?
Toyoo

These are some of the most common Questions (Q) and Answers (A) about Lion:
Q: What are the system requirements of the Lion upgrade?
A: Core2Duo, Core i3, i5, i7, and Xeon Intel CPUs with 2 GB of RAM in a Macintosh computer with 2 GB of RAM, and 4 GB (7 GB after installed) for downloading from the Mac App Store (Available in 10.6.6 and later). Unofficially, past upgrades have arbitrarily also required an additional 15% of the hard drive to be free for data.
Q: What applications are compatible with Lion?
A: http://roaringapps.com/apps:table provides a nice third party editable listing for people to include the compatible applications. Many of these compatibility entries came from before Lion's release. Please verify they are correct now that it has been released, and help edit it for more accurate data. Be sure to include any update version of Lion post release that you have found is or is not compatible with it, for the help of others who may be upgrading to Lion the first time. Additionally, as it was released, there is no Rosetta. This means any application that is stated to be PowerPC in the System Profiler, will not work with Lion, and needs a comparable application or upgrade to be compatible. The System Profiler is in Apple menu -> About This Mac -> More Info. Intel and Universal applications are on the whole supported, though may still need some tweaking before every feature is compatible.
Q: Are there any pitfalls to watch out for?
A: With all upgrades, backing up your data at least twice has been a given. Hardware can fail independently of downloads and upgrades, though may happen simultaneously. Software may be found to be incompatible that has not been tested with the new upgrade, or combination of other software that might be installed with the upgrade. It is also strongly recommended once your backup is complete, to shut down your computer, remove all but Apple wired keyboard and mouse (notebooks remove all input devices). Then once done, reboot, and go directly to the upgrade distribution system available. Third party system tools, modification, and "maintenance" applications should be verified as compatible, or removed until known to be compatible. Check with developers how to remove if it is essential to use Lion before those applications become compatible. Most "maintenance" tools that deal with system cache, prebinding, are not really maintenance tools. Ask on forum when are the appropriate times to use them before assuming they should be used for upgrades or otherwise.
Q: How can I get from 10.4 or 10.5 to 10.6.6?
A: Purchase a 10.6 retail installer from an Apple retail or third party reseller. It has a picture of a Snow Leopard on the DVD, and does not say Upgrade, Dropin, or OEM. Install it, and then install the 10.6.6 combo update from:
http://support.apple.com/kb/DL1349
Q: Is it true that I can only get it from the Mac App Store?
A: Presently this truth is based on current documentation as of the writing of this article. It may change, but we can't speculate as to its change. It has a better chance of changing if users request something different at:
http://www.apple.com/feedback/macosx.html
Q: What limitations might one encounter if it doesn't change?
A: First off the 7 GB space limitation on the hard disc after it is installed. Secondly, the size of the download file requires significant time, unless you have a high speed broadband connection. Times expected are below -
4 GB at:
5Mbps is 2 hours.
at 1 Mbps is 10 hours.
at 384 kbps is 27 hours.
at 56k kbps is 184 hours (nearly 8 days).
If you include the 10.6.6 combo update of 1.06 GB
add 29 minutes for 5 Mbps
145 minutes (2 and 25 minutes) for 1 Mbps
6 and a half hours for 384kbps
A 24 hour day and 15 hours (for a total of a minimum of 39 hours) for 56kbps
Remember the retail 10.6 currently does not include the App Store, and those upgrading from 10.5.8 or earlier will need to both buy the retail 10.6, and download the combo 10.6.6 update, not to mention ensure they have the correct processor and 2 GB of RAM. Finally once it is available, you'll have find out how long approximately it takes to install after the download is complete.
These times do not include installation time, which on a MacBook Pro 3,1 15" installing on a Firewire 800 Newertech Voyager with WD10ACS-322J80 drive, 10.6.7, took 1 hour and a half to complete the installation from double clicking the install command to the registration screen. These times may vary by connection speeds from a non-dedicated connection, or background application usage of the internet. Any applications running when the installation process begins might interfere with the installation itself, and they should be quit first.
The installer just before it starts has in its package contents an InstallESD.dmg file a DVD burnable image to install on additional computers in the home without downloading over again. So if you desire to reinstall without an extra internet download, extract that file, by selecting the installer in the dock, and control-clicking it, and revealing it in the Finder. Next Control-mouse click it, and select show package contents. Inside that folder is a Shared Support folder. That's where you find the DMG.
Q: If I purchased a Mac recently, can I get it cheaper?
A: Yes, visit http://www.apple.com/macosx/uptodate/ for details.
Q: When will Lion become available?
A: It became available July 20, 2011.
Q: Which Macs can run Lion?
A: Look at Apple menu -> About This Mac -> More Info, and see if you meet the Machine ID and RAM requires under the hardware. 2 GB is required for all These Machine IDs will run Lion:
Mac Mini 2,1 and later
MacBook 2,1 and later.
iMac 5,1 and later.
All MacBook Air.
MacBook Pro 2,1 and later
All MacPros.
The Macs with the Machine IDs below will not run Lion (x can be any number):
Mac Mini 1,x or PowerMac x,x
MacBook 1,x
MacBook Pro 1,x
iMac 4,x, 3,x, 2,x, 1,x

3-4 GB. RAM in Core Duo 20in.?

I was wondering if installing 3-4 GB of RAM in an early 2006 iMac Core Duo would work or cause Kernal Panics/other problems. I would like to run some Apple Pro Apps on the machine and the present 2 GB installed is not really enough when factoring in OSX's needs. Thank you.

Nope, 2 1GB modules is the maximum amount of ram that can be installed in an Early Core Duo.

Comparing ABAP development process with Model Driven Architecture concept

My Background
I am a postgraduate student writing a Masters Degree Dissertation titled An Investigation into how compatible ERP Development Process is with Model Driven Development Philosophy: A SAP R/3 Case Study.
The aim of this project is to compare ERP system development process with Model Driven Development (MDD) and to identify whether and how they can be used together. Model Driven Architecture (MDA) is Object Management Groups (OMG) flavour of the MDD philosophy and is the paradigm that will be used here.
I have chosen SAP R/3 as my case study in order to narrow the research and want to explore the development processes/cycle involved in using ABAP/4 to reconfigure/customize SAP R/3 system during implementation.
An overview of the MDA concept according to OMG is given below. Following this, Ive provided some questions that are open to discussions.
Overview of the MDA Concept
The Model Driven Architecture (MDA) is an approach to software systems development that separates the specification of system functionality from the specification of the implementation of the functionality on a specific technology platform. The MDA concept provides an open, vendor-neutral approach to system interoperability.
A recent study by the Middleware Company summarizes MDA paradigm as a development process that makes use of the following steps:
1.     Secure business requirements for an application.
2.     Develop UML diagrams for the domain model, independent of any particular technology (J2EE, Microsoft .NET, CORBA, etc). This UML model represents the core business services and components. This UML model is called Platform Independent Model (PIM) because it is completely technology-independent and will be the same regardless of whether you decided to use J2EE or .NET. You develop this UML model using UML modelling capabilities of an MDA-specific modelling tool.
3.     Build UML diagrams for the application, specific to a particular technology (J2EE, for example). This UML model will have design patterns. This UML model is called Platform Specific Model (PSM). You can build this manually, or you can generate much of it using an MDA tool and hand-tune only pieces of it that require customisation.
4.     Finally, generate the application code using an MDA tool. That is to say, instead of writing the application by hand based on the UML model, you generate the majority of it from the UML diagrams.
To develop an application using MDA, it is necessary to first build a PIM of the application, then transform this, using a standardised mapping into a PSM, and, finally, map the latter into the application code.
A mapping is a set of rules and techniques used to modify one model in order to get another model. In MDA, mappings are used for transforming:
1)     PIM to PIM. This transformation is used when models are enhanced, filtered or specialized during the development lifecycle without needing any platform dependent information. One of the most obvious mappings is the analysis to design models transformation. PIM to PIM mappings, are generally related to model refinement.
2)     PIM to PSM. This transformation is used when the PIM is sufficiently refined to be projected to the execution infrastructure. The projection is based on the platform characteristics. Describing these characteristics should be done using UML description. Going from a logical component model to a commercial existing component model is a kind of PIM to PSM mapping.
3)     PSM to PSM. This transformation is needed for component realization and deployment. PSM to PSM mapping are generally related to platform dependent model refinement.
4)     PSM to PIM. This transformation is required for abstracting models of existing implementations in a particular technology into a platform-independent model. This procedure often resembles a mining process that is hard to be fully automated. It may be supported by tools, though. Ideally, the result of this mapping will match the corresponding PIM to PSM mapping.
Questions/Discussions
1.     What specific stages are involved in development using ABAP/4? (e.g., requirements gathering, analysis, design, coding, etc)
2.     Do these stages fit into any traditional software development lifecycle? (e.g. waterfall model, v-model, etc)
3.     Which of the stages in (1) above best describes the Platform Independent Model (PIM) of the MDA concept above?
4.     Which of the stages in (1) above best describes the Platform Specific Model (PSM) of the MDA concept above?
5.     How does the Accelerated SAP roadmap relate to the MDA concept above?
6.     Assuming theres a change in business requirements of a company that could lead to reconfiguring/customizing the R/3 system, how is this achieved? For instance, if a model has earlier been developed for that particular process, how does the change in the model affect coding/modification?
7.     How is coding achieved with respect to the reconfiguration of the business models or reference models?
8.     Are all coding manually done or are there tools in the ABAP Workbench that enable codes to be generated automatically from the models of the system?
9.     How much time is spent in coding compared to developing business models like EPC models?

I've also read about the SAP Composite Application Framework (CAF).
But it seems that it's only for Java development....

Both these cards have been proven to work in both MacBooks. While some have had trouble with the /A card it CLEARLY appears to be a preferences problem. (just repair the preferences prior to installing the card)
Both cards require the Program Pacifist to install the enabler.
Pacifist is a small program that opens up .pkg installer packages and lets you install individual files out of them. This is useful if you need to install just one file out of a package instead of the entire package (for example, if you deleted Sherlock and need to reinstall it, but not the whole operating system), if you experience bugs in Installer.app that mess up your symbolic links, or if you just like a little more control over the installation process.
It can be downloaded free here. http://www.macupdate.com/info.php/id/6812
Open the enabler trough pacifist and click install. The program will place the items where they should be.
Please post your results with these cards!!!!!!

Here is my step by step MacBook Pro Core Duo 802.11n upgrade guide...

The only correction I would make to this is, the stainless tension bars at the top left of the Airport card should not be screwed directly into the card itself, but into the single screw hole directly above the card on the left side with the tension arms angeled down toward the card thereby actually holding the card in place via the tension or presure exerted. The two additional screws that come with the replacement card are not needed if you had and original card in place. There should not be any screws directly holding the card in place. The tension springs arms are only there to hold the card flat. If left as in your photo there could be some inadvertant arcing of static elec. transmitted to the card. THIS only applies to the MacBook Pro as the MAcBook requires being attached by two screws!!!!
/B Card: MacBook Pro--Courtesy of me: Same installeation as above,
I have now tried both of the different suggestions of getting internal 802.11n on an original MacBook Pro described on this forum.
1.) Dell internal 1500 Broadcom pci mini express card (Card Model # BCM94321MC), and
2.) Apple Pro’s internal (AirPort Extreme Upgrade Kit **NEW** Model BCM94321MC) New Part # MA688Z/B*
As you can see, both cards contain the same model numbers and incidentally, both only have ‘TWO’ antenna post and fit into the same space the existing PCI mini ‘G’ airport card held. Each installation took less than 20 minutes. Of course the second one took less time than the first.
I ordered the Dell card ($38 ebay) prior to learning about the Apple Pro card (Apple Store $43), however, both cards worked, performed, connected and were recognized equally well by the new ‘N’ AEBS. Both needed Pacifist for installation of the ‘N’ Enabler. Both cards show connection speeds at 130 in a mixed g/n environment, which appears normal per other post. Both cards performed identically with the new AEBS, except for the speed, as the original Apple 802.11 a/b/g card they replaced.
I referred to both the http://www.ifixit.com/Guide/85.0.0.html and www.xlr8yourmac.com/ instructions for the disassembly of my MacBook Pro.

seems to work. no driver problems or what ever!!

Jean-Paul,
You know the way I took out my AE card is the exact way I installed it. Do have a picture of the completed install you did?
I was soooo careful when I performed this task. Is your MacBook Pro a 17"?
That's what mine is. I am sure that is the difference between the two. I have the 15.2" Service Manual and I see the bracket is completly different then the 17".

Important flaw found on Core Duo Processors

Some of the users of SpeedIt reported a bug related to the readout of the temperature, we have been tested the digital readout and we discovered that the problem is related to a bug in the microprocessor.
This bug could be affect your MacBook is Speedit temperature readout is below 30ºC, and dont' change. If your temperature vary from 20 up to 80 don't worry you are not affected by this bug.
The bug is documented by Intel and happend only in some processors and is the following:
AE18 Processor Digital Thermal Sensor (DTS) Readout stops updating upon returning from C3/C4 state. (Source Intel Corp.)
If this is your case, we recomend to go to Apple to verify your computer, because in case of thermal problems the processor will never get protected. You can solve this issue too with the last firmware from Apple, Intel propose a solution via bios or efi.
Source
MBP - 15.4/2.0GHz Intel CD/2GB RAM/100GB SATA HDD/X1600 256MB/SD Mac OS X (10.4.6)

The problem is a defect in the Intel Core Duo processors. There is no workaround. I wrote Marcel, the developer, and he referred me to his FAQs.
Q: I have a Mac with an Intel Core Solo or Core Duo processor.
Sometimes, the temperature readings seems to "hang" and are no longer
being refreshed. Is this a problem with the application?
A: No, this problem is caused by an internal design flaw of current
versions of Intel Core processors. The Digital Thermal Sensors may
stop working when the processor returns from a C3/C4 power saving
state. Intel plans to correct this hardware bug for future steppings
of the CPU.

Intel core duo v dual 2.0ghz ppc

Hi.. I’m fed up with all the hype about the new imac core duo being twice as fast as the imac g5 2.1ghz. A lot of the magazines are also saying yes the core duo beats the g5 at this, that, and the next thing. What I’d like to know is how would the core duo have compared in performance had Apple had put a dual core 2.0ghz g5 in the imac like it done with the power mac range.
Just a thought
Cheers
Gerry

I'm curious about this too. In addition to what Gerald says, I note that there's also no mention anywhere of how the new dual core Intel processors perform as compared with, say, the Pentium 4 or whatever number they are at now.
As for the heat business, I see in MacFormat this month that IBM have announced a 4ghz - 5ghz powerpc chip. Apparently they have even tested one running at 6ghz, that they now plan to go in servers. So the PowerPC chip doesn't seem to be dying out now.
I am going to have to upgrade my 6500/300 sometime in the near future and as the Intel chips are going to force me to lose all my Classic software anyway, it seems sensible to work out what all the options are, if you get my gist.

Intel Core Duo MacBook 802.11n

I have a MacBook with Core duo. It can not recieve 802.11n, but I have seen a few different options for upgrading. One of those includes buying a Mac Pro Wireless Kit from apple and installing the card into the MacBook. I found this on the HardMac site. I have talked to almost everyone, but no one can give me a consistent answer. I know if I install the card myself the warranty will be voided no matter what, but if I have an authorized Mac Tech installs it for me will it void the warranty? The other thing is that if an authorized Mac Tech installs most things it will not void the warranty, but my only questionm is, if the Mac Pro card will fit into the MacBook and work while not voiding the warranty?

Hi haysman
From what I see you will not void your warranty if your macbook being repair by authorized service center and broken part has been replaced with similar one (within apple specs), not with modified one.
So altered the macbook specs might void your warranty.
To make it clear, consult your apple store, and your authorized technician, and asked your technician that can he or she guarantee that the warranty still good after they di that procedure.
And Core duo macbook age is almost a year old now, and if you don't have apple care, then you just wait couple more weeks and you can operate yours without worry about warranty.
I also seen one site that provide the kit and installation is also included, I'll post it later if I can come accross.
Good Luck.

Is there a difference between the Intel Core 2 Duo & the Intel Core Duo?

I am looking to buy a new laptop, and I wanted to know if there is a big or major difference between the Intel Core 2 Duo processor, compared to the Intel Core Duo.
I currently have a powerbook G4 and it has a 1.67 GHz PowerPC G2 Processor, which I have noticed isn't that great, I can't download the new snow leopard software update, nor watch movies from Netflex and other stuff like that. Its pretty annoying, so that is why I was asking about the difference between the other two processors, I want to know if it doesn't matter or which one is the best before I buy.
I'm pretty computer dumb when it comes to this stuff that's why I'm asking.
Thanks in Advance.

Core 2 Duo processors are newer and more powerful (and thus faster) than Core Duos. Apple's current notebook computers all use Core 2 Duos, so if you buy new, that's what you'll get. The earliest MacBooks and MacBook Pros had Core Duos in them, but the last of those models was discontinued late in 2006.

What to choose: MacBook Core 2 Duo or 2006 MacBook Pro Core Duo ?

I have this dilemma… want to buy an Apple laptop to use mainly as a desktop, hooked to an external 22” display, keyboard and mouse, as I’m using it for graphics apps (Adobe CS3) or video apps.
I have to choose between a Core 2 Duo MacBook or an 2006 Core Duo MacBook Pro.
(about the same price range, the Pro is still more expensive)
Don’t care much about drive space as the files are stored elsewhere, so my question is a propos the graphics capabilities (and maybe heating?) – which laptop is better to use heavily in clamshell mode to do graphic design and such?
Thanks.

Hi tdrb,
Both model are able to run Lightroom and Aperture:
http://www.apple.com/aperture/specs/
http://www.adobe.com/products/photoshoplightroom/productinfo/systemreqs/
but intel GMA is not that superb on 3D modeling if you planning to add 3D software later on, so I agree with mort for that.
Also macbook only comes in 13" while the smallest mbp comes with 15".
So if you only bring your portable laptop to clients, they will see better on 15" compare to 13"
Also on mbp you can choose matte or glossy lcd screen, and from my experience, I prefer matte finish when I do graphic composition.
For calibrate the tone color, you can use color guidience from pantone or other third party software and hardware like spyder, etc.
But the decision is yours to make, visit apple store run aperture on both and compare how that will response (remember 2006 model might slightly slower than new model on apple store) and which is preferable to your eyes.
Good Luck.
