Archlinux 32 bits on CPU Core 2 Duo machine

Hello
you see, in few days, I will buy a intel CPU Core 2 Duo, my question is: if I use Archlinux 32 bits with this CPU, the operative system will work using the two processors (I think this CPU have two cores)? or I must install Archlinux 64 bits for than it works using all processors?
Really I am a newbie in this matter...

There's LOTS of posts on ArchForums about 32bit versus 64bit.
A this point in time there is really no reason NOT to take advantage of your 64bit CPU, regardless of how much memory you have.
PS-64bit versus 32bit does NOT in any way effect how many CPU cores you can use. It effects how much RAM you can address.

Migrating files from Power Mac G4 to iMac Intel Core 2 Duo machine.

I'm hoping someone can help me figure this out.
I have a Power Mac G4 that runs OS X 10.2.8. I just got an iMac Intel that runs 10.5.2. Both machines have firewire ports but when I have them connected and try to turn on my G4 while holding down the "T" key, the G4 starts to boot up--then it shuts down.
Does anyone have any idea why this keeps happening? Or, alternatively, is there a way for me to transfer files from my G4 to my iMac without using firewire or a flash drive?

Click here for information; the position of the hard drive on the G4's ATA bus needs to be changed. If it is a SCSI drive, FireWire Target Disk mode cannot be used and the items need to be migrated by hand or the drive placed in an enclosure.

Unable to install Yosemite on my 2011 Macbook Pro (4gb Ram, 2.4 Ghz intel core 2 duo) machine.

Hello People,
I have been trying to download and install the new Mac Os Yosemite on my 2011 macbook pro which was previously running Snow Leopard 10.6.8. But, for some reason I am not able to install the file even when the download has been completed. This is the message i see every time i try to do a 'retry'. Can anybody please tell me whats going on with the installation process. and how can I fix this problem.

Your model uses:
Maximum Memory
8.0 GB
Memory Slots
2 - 204-pin PC3-8500 (1066 MHz) DDR3 SO-DIMM
So the specifications you provided will not work in your computer. Nor will your computer support 16 GBs.
A MBP 7,1 is a Mid-2010 model, not an Early 2011 model. If you truly have an Early 2011 model then it requires:
Maximum Memory
16 GB (Actual) 8 GB (Apple)
Memory Slots
2 - 204-pin PC-10600 (1333 MHz) DDR3 SO-DIMM
The specs you provided are also not suitable.

I have a Intel Core Duo CPU (not a Core 2 Duo) - Lion OS upgrade - is there any hope?

The APP store will not let me download Lion OS ... I have an intel core duo CPU - it is saying I need a Core 2 Duo. Currently running Snow Leo. OS 2GiG RAM with plently og spack on the HDD ... is their any hope - or workaround? Appreciate any help.

SOLVED ... when submitted I noticed outer responses on the right hand side ... the Intel Core Duo CPU is 32 bit while the Core 2 Duo (and Lion X OS) is 64 bit ... I will go away now and cry ...
PS I still love my (now considered old) MAC Mini ... ;-)

New Core 2 Duo MacBook Pro

So Apple released a higher spec MBP within a year of launching the MBP, and the new MBP costs less too. This is a bit sore for me, even though I have been using my MBP a lot since April when I bought it.
Now the entry level MBP comes with 2.16GHz Core 2 Duo, 120GB HDD(50% more), 1 GB RAM (again 50% more than the 1.83GHz MBP) and the DVD writer is now dual layer. All these upgrades in 6 months of my purchase. I felt a bit shortchanged.
I got some freebies,like a free upgrade to 1GB RAM plus some accessories, when I bought my MBP but none can compensate for the newer specs at lower price. The next time I buy a Mac, I am going to squeeze more freebies of the retailer to guard against such drastic upgrades.
It seems like Mac products obsolete at a much faster pace after the switch to Intel chips. Anyone from the PowerPC, Motorola or IBM chips era know whether the non-Intel powered Macs have longer lifespan?
MBP Mac OS X (10.4.7) 1.83Ghz, 1GB RAM, No Dual Layer DVD Writer
MBP Mac OS X (10.4.7) 1.83Ghz, 1GB RAM, No Dual Layer DVD Writer

I can't believe some people are complaining about the launch of a new MBP with Core 2 Duo's powering them!
The iMac was upgraded to Core 2 Duo around a month or so ago, this was a big give away folks, so anybody buying an MBP after the iMac upgrade must have no deductive reasoning or lives in a box (with no internet access).
Tan Kia, what do you expect? Technology to remain in one place, never to move on and never improve? Do you read the discussion threads on here? People have been talking about Core 2 Duo machines from about May or June onwards (if not before that).
If you were so interested in the Intel Mac's why not shimmy over to Intel's website, they explain in detail where they're planning to move their technologies to and even give a time frame for the release of these new technologies, like for example a Quad Core Xeon in January 2007 - hold on to your hats Mac Pro owners - are you going to feel cheated too? Knowing this I still bought a Mac Pro. Will I feel cheated when the quad core beast is unleashed? Nope. The current one is way fast enough for my needs. If it starts to slow down and ceases to perform (which could take years), then I will replace it with a faster more powerful machine. It's the best in it's class at present and a joy to use, as I'm sure your MacBook Pro is.
I held off buying a MBP as soon as they were first announced because they only had a 32 bit CPU. I checked Intel's site and saw their roadmap for Core Duo. It was obvious that Apple would launch an upgraded MBP with a 64-bit Core 2 Duo at some point before the end of 2006 (and no doubt a quad core before the end of 2007 and so on as processors evolve more and more cores).
The fact is you made a decision to buy a MBP when you did, becuase it suited you then. There's no need to feel sore about your purchase. You have a MacBook Pro, one of the best laptops around (although not as good as the new upgraded MacBook Pro) it still performs well for you.
Apple didn't need to upgrade their PowerPC machines as often, as it was a completely different architecture working differently to x86 based PC's. Now that Apple have (in some people's views) gone to the dark side (Intel x86), Apple are now on the same footing as PC makers.
Intel launch new technologies quickly, PC makers respond quickly. It's always been the way with PC's. If Apple want to compete squarely in the same market as PC's, Mac's run Windows too, they have to lauch new technologies either before or as soon as a competitor does. If they don't, Apple couldn't trumpet their best, fastest, cheaper (as far as direct comparisons go etc) claims.
Just enjoy your computer and be grateful you bought a Mac over a PC.
Everything constantly evolves . . . evolution is the natural order.

MacBook Early 2008 Core 2 Duo/Penryn Series - Unable to upgrade from Lion to Mountain Lion ( Looking For A Fix )

I own a MacBook "Early 2008 Core 2 Duo/Penryn" Series has Intel Processor (T8100 (2.1 GHz ) / T8300 (2.4 GHz)) 45 nm "Penryn" processors, 4 GB of 667 MHz DDR2 SDRAM (PC2-5300) installed in pairs (two 02 GB modules), a 160.0 GB Serial ATA (5400 RPM) hard drive with "Sudden Motion Sensor" technology, an 8X dual-layer write DVD±RW/CD-RW SuperDrive, an Intel GMA X3100 integrated "graphics processor with 144 MB of DDR2 SDRAM shared with main memory", and a 13.3" widescreen TFT active-matrix "glossy" display (1280x800 native resolution). It also includes AirPort Extreme (802.11a/b/g/n), Bluetooth 2.0+EDR, Gigabit Ethernet, a FireWire "400" port, two USB 2.0 ports, optical digital audio in/out, and video out capabilities (mini-DVI) that supports an external display. These models also include the "scrolling Trackpad", built-in iSight video camera, "MagSafe" power connector, "flush against the bed " keyboard that does not touch the screen” and "no moving parts" magnetic latch that "catches without a catch".
Now to the adventure on this, the above model (stock) ships with a Operating System MAC OS X Leopard which was succeeded by MAC OS X Snow Leopard ( $19.99 / INR 1060.00 approx. ) which was again upgraded to MAC OS X Lion ( $19.99 / INR 1060.00 approx. ) and the latest one is MAC OS X Mountain Lion ( $19.99 / INR 1060.00 approx. ).
Interesting part to all this technological babble is how APPLE INC forces you buy their product both hardware and software. Now, I have this old MacBook Early 2008 Model PC and I took it to the shop and I thought I would upgrade the software (OS and APPS) so I take it to the iStore ‘Rescue Centre’, as APPLE INC calls it world over, they say you will have to upgrade it version by version and each version would cost you a licence fee! SO the cost break up would be, I’m currently on MAC OS X Leopard to be updated by MAC OS X Snow Leopard ( cost $19.99 / INR 1060.00 approx. ) which again to be upgraded MAC OS X Lion ( cost $19.99 / INR 1060.00 approx. ) and then to latest one is MAC OS X Mountain Lion ( cost $19.99 / INR 1060.00 approx. ) which means I have to pay INR 3210.00 to upgrade the machine and I agree to pay for that and after two upgrades the third one(that is the latest version) was not compatible with my machine because of inferior/outdated hardware e unit and If I want the new operating system then I told to buy the new machine which costs between INR 90,000 to INR 1,40,000!!
That … ***** !!!
So I’m here looking for somebody, anybody, whether you would be able to help me with my MacBook which is early 2008 Core 2 Duo/Penryn Series (for exact specifications, see above) and I currently running Lion on it and wondering is there any way I can upgrade this to Mountain Lion?

Your early 2008 MacBook cannot be upgraded to Mountain Lion. The reason is that Mountain Lion is entirely a 64 bit operating system, and cannot use any 32 bit components. Lion, while also 64 bit-based, can use some 32 bit components, and thus would work on all Core 2 Duo machines. This article has more details.
The center you went to was incorrect when they said you have to upgrade to each operating system. You need to be at Snow Leopard in order to access the App store to download Mountain Lion. You don't have to install Lion to get to Mountain Lion. See this Apple page on this.

Question: I want to update to the new LION OSX, but it says that I need to at least have an Intel Core 2 Duo. When I click "about this Mac," it says that I have a 2.16 Intel Core Duo. Is there a difference between the "Core 2 Duo" and the "Core Duo"?

Well, my title basically asks the question that I am seeking an answer for. Im not sure what year my MB Pro is, and I cant exactly find it on the Apple site. Its a 2.16 Intel Core Duo, 2 GB 667 MHz DDR2 SDRAM. All I see (dating back to 2007,) is Intel Core 2 Duo on the apple site. Im pretty sure (but not 100% positive,) that my MB Pro is a late 2008/early 2009. Just trying to figure out if I can install LION OSX or not, since it requires atleast intel core 2 duo, and mine says I only have the intel core duo. Any help would be appreciated. Thanks!

Core 2 Duo and solaris x86 11/06 works for me

This is FYI, since I seen (and posted) problems, but I haven't seen the solution posted.
I have successfully gotten solaris x86 11/06 to install and run on my core 2 duo machine. I had tried solaris x86 06/06, but I could only run in 32bit mode until patch 118855-19 was installed. It looks like 118855-33 is the baseline for 11/06.
With 06/06 I had to edit the grub command and add " kernel/unix" to the end of the 2nd line. This would force 32 bit mode rather than 64 bit. If I tried 64 bit, it would enter an endless reboot cycle. Once I installed the patch to 118855-19 I could run solaris 10 06/06 in 64 bit mode without issue.
Again, since solaris 10 11/06 is at 118855-33, it runs on my core2 machine straight from the install.
Hope this helps

On a laptop there is little point with running a 64-bit operating system unless it physically has more than 4gb of ram, or if you are processing datasets exceeding 4GB of ram. Unless you're into assembly or use Solaris for some reason to manipulate media, little is to be gained by using 64-bit versions if anything. The increased pointer, integer, and padding causes more memory to use for the same software, most software on 64-bit operating systems runs in 32-bit mode because there is no need to have 16 exabyte memory addressing capability for anything but media encoders, giant databases, or extremely bloated single-threaded software. Sun Java Creator takes a heck of a lot of ram, but even at peak it's still under 4GB. If you move files bigger than 4GB, the ability to memory map all 4096MB might have less overhead on a 64-bit operating system, but generally from an end-user perspective, especially on a fast Intel or Opteron system, you won't notice the difference much. Solaris is bi-arch, a large chunk of Windows Vista and XP x64 is bi-arch, and most of FreeBSD and Linux are bi-arch in 64-bit versions, as I said, no point in making everything 64-bit. 64-bit device drivers is an issue for every OS, you should stick with 32-bit on a laptop, and hold off on desktops unless you need extended assembly registers available only in 64-bit mode.

What's the difference between an Intel Core 2 Duo and Dual-Core Chip?

Does someone know if there's a difference between these two chips?
Thanks,
Paul

Yes. The Core Duo is a 32-bit processor, the Core 2 Duo is a 64-bit processor. The C2D is the second generation of Intel's Core lineup and is considerably faster than a CD at the same clock speed. Core 2 Duo processors are also available with four processors on the chip and are pin for pin replacements for the processors used in the Mac Pro - thus providing 8 processors rather than 4.
You can find a basic comparison here: http://www.apple.com/macbook/intel.html.
You can visit Intel's web site to find out everything there is to know about both processors.

Anyone tried LPX on a core 2 duo iMac? How's performance?

Hi all,
Thinking of upgrading from LE8, and unsure whether to do so now, or whether to wait until I upgrade my machine (which probably won't be for ages). Have any of you tried installing on a core 2 duo machine? Can you comment how the performance is? For my purposes, a usual project might be 20 tracks or so, of which 3 or 4 will be sampled/MIDI instruments, and with a few effects here and there.
I'm running a 3.06GHz core 2 duo iMac maxed out at 4GB RAM. The RAM is probably my main concern, given that I'll also have to upgrade from Snow Leopard to Mountain Lion (which I don't particularly want to do unless I have to!).
Thanks for your help,
Jo

Hi Mate, Sorry! Yes, it runs really well, i'm on a 2.6ghz with 4gb ram and it seemed to run better than Logic 9 on the same machine - But then, this is a clean install of OSX, so may explain that - Being fresh and all.
It was a bit beach ball-y to start with, but i guess it was still loading everything up and refreshing the library etc., since that initial session it's been good without any beach balls going on.
I loaded up 15 tracks with an assortment of different instruments within the Logic suite and all was good. It's not as snappy as my other machine (i5/8gb) but i think that could be the memory difference - Definetly get yourself an additional 4gb.

Intel Core 2 Duo...good video making system???

First off...we have tried in a school district environment with our Mac lab on a network to start a videography educational direction. I have about 60 hours invested after school hours in this learning curve, and the last week especially I've called, "**** week"...
I have a video as the art teacher I created that is 55 minutes long...but to put the long story short, couldn't get iMovie5 to finish with the second half of audio yet to go. It dogged down, video freezes up while audio can be heard, hitting the stop command takes about 20 seconds more for it to respond. Sounds like a RAM problem...or size problem, but in another forum we've determined it is not. I still show 122GB of space left. The problem is that apparently in the transfering of data to our tech's computer room with the larger server and network, something is getting lost and the project has its problems.
So...we approached our grant writer (as we have some money to use) AND THIS IS WHERE YOU COME IN...
We have determined it might be best for us to have a stand alone machine. No internet, no network chattiness of machines and a server.
Our tech looking on the educator's discount machines put a proposal together for this Intel Core 2 Duo machine....plus 500 GB...
I would like some feedback, one...the tech thought that perhaps this computer might come stock bundled with iMovie and iDVD already on the machine. Is this true...? Can't see that on the apple.com pages. Secondly, would you recommend the Final Cut Studio 5.1 for an additional $499.00 if there is no iMovie and iDVD over ordering the latest version of iMovie/iDVD?
would you recommend Final Cut Studio 5.1 even if the computer comes stock with iMovie/iDVD and if so...why?
thanks

Hi there, this week i became a core 2 duo iMac owner after previously using a G5 iMac as my main editing system. I have the 17" C2D iMac now and it is approx x3.5 - x4 time as fast so whether you go for iMovie or FCP your gonna be sorted, just make sure you dont go for the really cheapy that uses the shared grafix, and the more ram the better.
As far as the system go's i like many others would class it as a big no no to go for a large internal drive to store video, audio etc. You need to bare in mind that your OS is on the internal drive and the two will be competing,thats where the problems start. I would recommend going for the bog standard 160Gb and investing in an external FW400 drive to store your project files on, if you can blow the budget and get a 24" iMac then they have FW800, even better. The price Apple charge for HD's i wouldn't imagine it's any less costly, just research the Firewire drives and make sure you get a drive that has the Oxford 911 chipset, they are renowned for providing the best performance on macs. Check out OWC computing over in the states for these types of drives.
As for which software you go for will depend on the complexity of your projects and how much freedom you want. Final Cut Studio is a phenomenal package and i absolutely love it, i have to be honest it took several months of fairly intense learning to fully get to grips with how the apps integrate but once you learn them, literally, the sky is the limit.
I personally find iMovie somewhat restricting, i.e. you can only have one stream of video and i think two streams of audio. On the flip side it has some great transitions and sound effects that allow someone with very little editing/film knowledge to make a fairly cool video. I'm guessing the question here is fun vs. complexity.
I mainly find myself using FCP to edit and iDVD to author. I have the freedom to do what i want in FCP and then just modify one of the iDVD templates to give a nice front end. DVDSP4 isn't something i've found you can enter in to lightly, i.e. you have to manually link everything but the flips side is total control over the project.
Hope it Helps

Intel Core 2 Duo or Core Duo???

Greetings! I have a 17" MacBook Pro that I purchased last August 2006. How can I tell if it has the Intel Core 2 Duo or Core Duo processor?? Apparently, there is a difference in the maximum memory that can be installed: 3 GB for the Core 2 Duo and only 2 GB for the Core Duo. Any know how to determine the processor type?
Thanks & God Bless!
Rick

i was only half serious about the rumour sites thing.. actually you're the perfect example of someone that has the right attitude to making a computer purchase. you understand that all manufacturers including apple aren't about to start yelling from the rooftops that a machine will be replaced with a faster one coming up in a couple of weeks. it just makes no sense to freeze the sales of the current machine prematurely, and people know they can always pick up remaining stock of the outgoing model at a reduced price after the new one is announced. you've also stated that while the new machines seem a little faster (well duh what's new under the sun?), you're happy with the performance of the one you have, and it does what you need it to do.
I think it's only ever a good idea to keep the most casual eye on the rumour sites, just to get an inkling of any possible new developments. but it's pretty much a dumb idea to base your shopping on what they say. in my case, I waited for the core 2 duo machine because I happened to be looking to buy one literally just when is started making the tech news that the core 2 duo chips for laptops were making their way into machines, and some PC laptops were already shipping with them. it seemed the sensible thing to do to wait a couple of weeks before placing my order, and I was in a position where I could wait anyway. i also knew that I'd be waiting at least a couple of weeks if not more for any machine I ordered to be shipped because I was always going to order a custom configuration anyway. so in my case it paid off.
but I read a lot of people putting off buying a machine for frankly silly reasons, fed by the rumour sites. a lot of audio pro logic users (like myself) are fixated on the idea of waiting for the next generation intel portable chips because of a combination of some kind of power **** fed by the rumour sites. and also a lot of them are also PC users, and so they are terrified that whatever they buy now might be a bad choice because leopard is around the corner and it might change the ballgame, causing problems with machines bought earlier.. it can all be quite misleading and make you wait without a machine for no good reason. and then when you look at the intel info on what the next series of C2D chips will be, it's only a speed bump to 2.4Ghz above the 2.33 that it currently tops out at. I'm sure there are other enhancements too, but it's hardly earth-shattering. and then on top of that, there's just no way that leopard is going to have any issues at all, esp compared to vista, with recent machines, and probably not even much older ones too. in fact, sometimes it's a bad idea to buy a machine that comes pre-installed with the latest OSX because it has been the case in the past that the firmware on these machines doesn't allow them to retrograde to work with a previous OS version. this can be a big issue for some users! for example if you are an audio pro, and you use digidesign hardware, they are notorious for taking a long time to release drivers for new OS versions, and not only that, their previous drivers often just won't work at all with newer OS's until they release their newest driver, unlike other manufacturers whose drivers often survive the transition without requiring an update just to stay functional. so in cases like this, listening to the rumours too much and holding off on buying can actually be totally the wrong thing to do.
anyway, I've just had a little rant haven't I? glad you're happy with your machine, and for anyone else reading, I hope I've given a little perspective on the matter.

Core Duo and Core 2 Duo

So, my black 2 ghz Core Duo is in need of a new hard drive. Of which I'm waiting for a warranty replacement.
My wife's white 2.16 Core 2 Duo macbok will be mine for the next week. Will my RAM from the black macbook work in the white macbook? Are they interchangable?
TIA!

All white and black MacBooks come from the factory with PC2-5300 (DDR2 667) memory - more than likely CL=5. They should be interchangeable, but there is the caveat about total memory supported in various versions of the MacBook.
I'm not sure why you'd want to do this unless somehow your Core Duo has more memory than the Core 2 Duo machine. The standard build for the Core Duo MacBooks was 2x256MB, while the standard build for the Core 2 Duo 2.16 was 2x512MB.

Refurb Macbook Dual Core or New Macbook Core 2 Duo?

OK, I admit I didn't do the research. I bought a refurb MacBook Core Duo 2GHz with the superdrive. Nice machine, and in good condition, as far as I can tell (it arrived tonight).
So suddenly I'm thinking of long term holding of this MacBook, and today I read somewhere the Core 2 Duo runs everything 25% faster than the Core Duo. So right away I'm thinking--whoops!
Are the Core 2 Duo machines significantly faster/better than the older Core Duo machines? In other words, should I rush this one back to Apple and buy the newer one at the couple hundred bucks more it'll cost?
Quick responses (and links to reviews etc.) much appreciated.

Hi Pier,
We have both a White Core Duo 2Ghz (Yonah) and black Core 2 Duo 2.16 Ghz (Merom)....each one gets equally warm, esp. when running VMWare/Windows.
As far as speed, I really don't notice any difference, esp. w/ the 2GB of RAM in the 2.16Ghz model....I think the only thing I notice different is startup speed and that's it (difference of maybe 2-3 seconds).
My g/f uses NeoOffice, Office X, iWork '08, LaTeX, Grapher, VMWare, Geometers Sketchpad, etc., and usually they're usually all running at the same time; the Macbook barely breaks a sweat on the Yonah chip.
I'd say keep the refurb Cure Duo and just max the Ram. I still have a 1.66Ghz Yonah-based PC notebook (HP Pavilion) and it's still plenty fast.
My advice...save your money and get an ext. drive for backups, get SuperDuper, and max the RAM.

Core 2 Duo vs Core i7

I have a MBP 8,2. I Just purchased my dad a MBP 5,5. I am not sure what year that apple switched from core 2 duo to the i7.. But it seems strange to me that reading online everyone claims that the i5 and i7 models are much superior... Every core 2 duo machine I have used seems to be much quicker then the i7... Now my machine is a quad core so i can run more logic tracks (which is nice for me).. But other than this, I am jealous of the older (2009) MBP (Core 2 Duo) machine then my own (2011) MBP (i7).
Just testing application opening speeds my computer took 15 seconds to open Maps app... While my dads old one took only 5 seconds... This doesnt make sense and would seem to me that the newer models should be faster then the older models..

That video is interesting.. But I am very reluctant to believe it. To do a true test you wouldnt test restarting. You would test a cold boot.
Also, he shows youthe actual SSD that is intsalled on the Core2 Duo in the Syetem Profiler. Then claims that the i7 has an even faster SSD, but does not show what is actually installed in the System Profiler which makes it very suspect.
