Mac Pro 8-core X5365 CPU temperature

I've got an 8-core Mac Pro which is crunching SETI@home 24/7, with Hardware Monitor monitoring the CPU temperatures and other vital stats. After reading the Intel Quad-Core Xeon Proc datasheet, I'm a little edgy about the operating temperature of these X5365 CPUs, currently registering at 65 - 70ºC on load for each temperature diode, and fail-safe temperature set to 73ºC to disable SETI@home via Hardware Monitor. I also have smcFanControl speeding up the fans because my ambient temperature varies thanks to myself being in a tropical region, my ambient temperature can reach 33ºC at times, but down to 28ºC when air-conditioned.
My question is, what is the maximum temperature for these CPUs before they run into the risk of being fried/permanently damaged..?
Inputs from the Mac Pro-DC/grid community are also welcomed here.
Thanks.

my 8-core is running seti 24/7 since may without any problem, although my ambient temps dont rise above 30 degrees centigrade...and that's using the optimised apps which make the processor run hotter
the fans on the machine run 600-2000 rpm all day and all night, i dont expect it to lessen the life of the machine whatsoever. it should be capable of running flat out all its life, that is, after all why we spend so much on these machines in the first place !
if you only use 4 cores perhaps you should buy a 4-core mac ? he heh just joking...
as mentioned earlier, when things get really too hot the OS will shut the system down, and if that doesnt happen then the cpus themselves will shut down...
the heatsinks and fans on these machines are fully capable of coping if your macine is running withing the specified ambient temp range which for the mac pro is 10° to 35° if your seeing ambient over 35 then smc fan control is probably a good idea otherwise it should be fine

  • Switching an old dual 1.8 to a new mac pro 8 core questions

    hi
    Tomorrow i am getting a new Mac Pro 8 core 2.8, the basic model, 2 gigs ram (for now) and the on 320 gig HD. I am not a great mac person, i used my old one for some final cut express stuff and that was about it. so i was wondering if someone could answer these questions for me
    1) will final cut HD load fine on the new one in terms of licenses? in that, will that license or serial number i have used on the old one be ok on the new one?
    - same things for aperture, these are really the only 2 programs i have and really need on the new one, till i move up to final cut full
    2) i have an older "projects" western digital HD with the projects, pics etc on it, can i swap that HD into one of the new slots till i get another newer drive? its sata, but i am not sure what speed?? its probably 3 years old now
    3) what exactly does the new mac pro come with?? in the apple store it really doesn't go into it, i have ilife 05 on my old one, is it worth getting the new one? does it come with things like that?
    4) i mainly do home movie's and video editing on my mac, if i end up with final cut studio 2 i think it is, what is the recommended RAM?
    5) where is the best place to buy more RAM and HD's for the mac? i will need or want 3 more 500 gig min, 7200 speed drives and probably 2-6gigs more ram.
    ok, that should confuse me pretty well for a while
    thanks for any help!

    1. As long as the software is not installed on more than one CPU you are not in violation of the software license. You will use the same serial number.
    2. Any SATA drive can be installed in the computer.
    3. New computers come with OS X and iLife pre-installed. Also trial versions of iWork, MS Office, and Quicken's Quick Books.
    4. I would recommend at least 4 GBs of RAM.
    5. You can buy RAM from any online vendor that has the proper type of RAM with the proper heat sinks. Suitable vendors are Data Mem and MacSales.com. Hard drives are available at any number of online vendors such as:
    MacSales.com
    Buy.com
    NewEgg.com

  • Opinions, Mac pro 12 core or 6 core for video editing?

    Hello everyone,
    I know that this a most likely a rhetorical question but i currently have a mac pro 12 core 2.4ghz 12 gigs of ram (plan on upgrading to 32 gigs) and a 6 core 3.33ghz 12 gigs of ram. I do a lot of video editing (starting to use Final cut pro X) and i do a lot of visual effects work in Adobe after effects and 3D animaton work in cinema 4d. I am only keeping one of the computers.. what are your guys thoughts? Should i keep the 12 core even tough it has a lower clock speed, or should i keep the 6 core since it has a higher clock speed? I dont mean to ask such a dumb question but i want to hear what your guys thoughts are.
    Thanks in advance!

    If you rely on cpu alone, it may look like it is working, or lagging, or wating, but with the combined power of GPGPU can make all the difference.
    Communicating over Quick-Path is okay but Intel knows that they need to up the GT and L3 cache to improve it more. ie, there are times when two 6-core Mac Pros are faster than one 12-core, given the same GHz.
    the real reason people bought dual with lower clock was hoping it would do more work, but when you have 3.33GHz a lot of work that cann't be dispatched and is not multi-thread or multicore all benefit.
    W3680s are relatively cheap @ $600, you will not find X5600 sets unless you can make your system pay for whatever you throw at it and do so in a year to write it off and pay for doing more projects and more income.
    This guy goes kind of crazy with custom setup 12-core 3.33s, 960GB SSD PCIe and 96GB RAM.
    More RAM helps some areas but not rendering. So find the bottlenecks or throw everything at the problem and hope.
    $1660 a piece X5680 - $1470 on Amazon
    http://ark.intel.com/products/47916/Intel-Xeon-Processor-X5680-(12M-Cache-3_33-G Hz-6_40-GTs-Intel-QPI)
    http://www.amazon.com/Intel-X5680-Processor-Socket-LGA1366/dp/B003ELYSJQ/
    Only if you shop ebay for used parts, and by then whatever Intel and Apple agree on next go round new is a better system solution most of the time than to throw $3000 into an older system. $3k would be another 6-core 3.33 if that helps.

  • Mac Pro 8-core slow compression on MPEGs

    My Mac Pro 8-core with 9GB of RAM is very slow compared to my G5 Dual 2.7GHz with 2.5GB on doing MPEGs... the problem only exist with MPEGs in Compressor 3 or 3.0.1. All other formats the Mac Pro gives the G5 a thrashing. I've read in here that many people have it the other way around.. that MPEGs are supposedly more multiprocessor capable.
    Both with using virtual clusters (4 instances) and no virtual clusters I'm getting around 52 minutes on a DVCPRO HD 720/24p clip which is exactly 6 minutes in length. The G5 dual 2.7GHz with 2.5GB of RAM did this job in 21 minutes and 33 seconds.
    On the Mac Pro I've erased my system and reinstall with just FCS2 on the system... still the same speeds. I've taken out the 2x4GB sticks.. still the same speeds. I've moved the 6 minute clip onto different volumes still the same problem. I've tried other DVCPRO HD clips.. still the same.
    The problem only happens with the DVD 90-150 presets regardless of quality. Does not occur with the HD DVD presets or H.264.
    Mac Pro configuration:
    Mac Pro 3GHz 8 core
    9GB of RAM (2x512mb, 2x4GB)
    ATI Radeon X1900 XT with dual 30 inch ACDs
    3TB of internal Hard Drive storage... one unraided 750GB for system files.. 3 RAID 0 for Scratch.
    AJA KONA LHe capture card
    Runiing Final Cut Studio 2 with compressor 3.0.1
    G5 configuration:
    Power Mac G5 Dual 2.7GHz
    2.5GB of RAM (2x256MB, 4x512MB)
    NVIDIA GeForce 6800 Ultra DDL with 23" ACD
    250GB + 160GB internal Hard Drives.
    Running final Cut Studio 2 with Compressor 3.0.1
    Any help would be appreciated... I've tried everything in my technical powers to solve this one.

    Made a new DVD: MPEG-2 custom setting with an average bit rate of 7.7Mbps... still slow... about 50 minutes to complete the 6 minute DVCPRO HD 720/24p clip. The compressor daemons are averaging around 60MB of Real Memory and 450MB of virtual memory. I really think this lack of memory usage is causing the problem. This only happens on the DVD 90-150 MPEG-2 presets. Any other format is grabbing at least 200MB per daemon... including HD DVD MPEG-2 and DVD MPEG-1. I will continue to test different settings and pray for a change.
    Getting all compressord (Not Responding) for each 4 instances in the virtual cluster when I run the DVD 90-150 MPEG-2 presets. The batch monitor is still reporting progress. Real memory usage fluctuating in the 60's per daemon and around 450MB's for Virtual Memory. Compressor daemons not responding is a problem solely on the DVD 90-150 MPEG-2 presets.
    No major difference in speed between CBR or VBR custom presets... memory usage still in the 60's per compressor daemon.
    With Job Segmenting turned off & One Pass CBR... 20 minutes to job completion. The memory usage is around 65MB of Real Memory and 450MB of Virtual Memory. CPU activity on the one active compressor daemon is averaging around 460%.
    One thing I am learning is that processor activity as reported by Activity Monitor is not a reflection of speed.

  • Slow Performance On Mac Pro 12-Core

    Hello Everyone,
    I just recently purchased a 2012 Mac pro 12-Core and i have been getting unbelievabley slow performance with it. I am using Premiere Pro CS6 and it seems that the footage can sometimes get a bit laggy at times and not play back smoothly, sometimes rendering can take a bit of time as well. However here are the specs of my system:
    Mac Pro 12-Core 2.4GHz (2.67GHz Turbo Boost)
    40GB of Ram
    ATI 5770 Graphics Card
    1TB scratch disk (with a user on the drive that i can boot into)
    OCZ 120GB Vertex 3 SSD OS/APPS drive
    First question i would like to get answered once and for all.. Did i make a bad decision by purchasing a computer with such a slow clock speed (2.4GHz)?? I figured since The new editing software is switching to 64bit it shouldn't depend on clock speed anymore? (i just want to be sure that i purchased a more than capable machine) However i will be buying a Samsung 840 Pro Series 256GB SSD Drive for Scratch within the month. (I dont have the budget to buy a Raid controller yet to utilize 6GB/s transfer speeds, so 1 Fast SSD drive will have to do for now)
    I should mention the current SSD drive im on right now only has 13GB remaining, would that affect performance? Also, my 1Tb media drive is filled up with CRAP from my previous computer (Migration transferred EVERYTHING to that drive, only 120GB remains) would that drive with the media im working with affect performance too? Also just as a test, i took some footage from my GoPro Hero 3 camera and put it on my SSD to see if that would eliminate the lag, but still lag was present in Premiere.. (the footage was in a crappy .M4P format, so that may have affected it, but I dont know)
    Any suggestions are greatly appreciated!
    -Thanks in Advance!

    The new editing software is switching to 64bit it shouldn't depend on clock speed anymore?
    Wrong, clock speed is everything.
    I should mention the current SSD drive im on right now only has 13GB remaining, would that affect performance?
    No, not really.
    Also, my 1Tb media drive is filled up with CRAP from my previous computer (Migration transferred EVERYTHING to that drive, only 120GB remains) would that drive with the media im working with affect performance too?
    When fill rates go up, performance goes down. With almost 90% fill rate, the disk performs only at around 50% of a new disk.
    Two disks is absolute bare minimum, and your cores will constantly be waiting for the disks to read or write data, sitting idle most of the time.
    Also just as a test, i took some footage from my GoPro Hero 3 camera and put it on my SSD to see if that would eliminate the lag, but still lag was present in Premiere..
    GoPro material requires a very fast computer, which yours is not with the low clock speed, outdated E5620 CPU's, only two disks, and a non-CUDA capable video card.
    Take a look at the PPBM5 Benchmark and look at the system at rank # 854, which is a MacPro, very similar to your system, dual E5620, AMD video card, less memory but uses three disks.
    So, your system would be around the same rank as the one above, among the slowest 25% of all systems and something like 10 - 15 times slower than a fast system. You tax your system to the extreme with the GoPro Hero3 material, and the consequence is the slow performance you see.
    Sorry, not much you can do, other than get a new system. If you sell it now, it may get you a price, good enough to get a much faster Windows system and maybe even keep the change.  Simply said, you bought a MacPro for € 3.5 K, sell it for € 3 K, buy a PC for € 2.5 K that is around 5-6 times faster and your loss is recovered.
    However i will be buying a Samsung 840 Pro Series 256GB SSD Drive for Scratch within the month
    What a pity the MacPro does not have SATA 6G ports, only SATA 3G, because then that SSD will run at almost half speed.

    I have a Mac Pro Quad Core Dual 2.8GHz (Xeons) with 4GB of memory (2 x 1GB Apple modules + 2 x 1GB other brand - Shown as "Manufacturer 0x855D") and now I want to fill the other 4 memory slots by adding an additional 16GB (4 x 4GB modules) for a total of 20GB of RAM.
    My 2 questions are:
    1.- In which order/pattern should I install these new 4 X 4GB modules along with my original Apple 2 x 1GB modules and the "Manufacturer 0x855D" 2 x 1GB modules the best way (for better performance)? - I have heard stories that if I do it improperly, I could slow down my Mac Pro...
    This is how I have them configured right now:
    Raiser A / DIMM 1 = 1GB (Manufaturer "0x830B") - I assume this is the Apple memory, right?
    Raiser A / DIMM 2 = 1GB (Manufaturer "0x830B")
    Raiser A / DIMM 3 = Empty
    Raiser A / DIMM 4 = Empty
    Raiser B / DIMM 1 = 1GB (Manufacturer "0x855D") - How can I find which manufacturer is this?
    Raiser B / DIMM 2 = 1GB (Manufacturer "0x855D")
    Raiser B / DIMM 3 = Empty
    Raiser B / DIMM 4 = Empty
    2.- What brand would be most compatible to work with my Apple 2GB (2 x 1GB) factory memory? Kingston? Crucial? Mushkin? iRam? Corsair? OWC? (Does OWC sell their own brand? or which one do they carry?-its not specified on their web)
    Thank you so much in advance for all your help!

    Memory Tests- "2008" Mac Pro
    Ram should be installed minimally in matched pairs and optimally in matched quads. This means the memory modules are the same size and specifications. They should also be equipped with the Apple-certified style of heat sink.
    Brand really doesn't mean much as long as they work.

  • How can I hook up 3 screens to a Mac Pro 8 core 2010 model?

    How can I hook up 3 screens to a Mac Pro 8 core. One is a 23' Apple Cinema Display, the second is a 20" Apple cinema display and the 3rd is a 32' Sony Bravia HDTV (connected to mini port with mini/HDMI connector) Do I need to buy another video card? I have heard  about 4 different scenarios about this, and they all sound a bit complicated. I thought that you could automatically connect 3 displays with the card that comes with the MacPro. It has a DVI port and 2 mini ports, so it appears that would be for 3 displays. But this is where it gets strange. Any thoughts?

    Which video card?  5x70?  If you read about the various scenarios thern for 5x70's you need two active adapters for thee monitors (TV considered a monitor).  And you should have seen references to these apple docs:
    Mac Pro (Mid 2010), Mac Pro (Early 2009): Issues with three displays and multiple DVI, HDMI connections
    Mac Pro (Early 2009), Mac Pro (Mid 2010): Supported display configurations
    It's not really complicated.  Search out the appropriate adapters and hook 'em up.   For the 23" and 20", if they are DVI, you need single link adapters.  For the TV, if you end up using the DVI port for it (because possibly you can't find the appropate adapter cmbination) then you need to handle the audio separately since DVI doesn't carry audio.

    Welcome to Apple Discussions!
    Do you keep your data backed up?
    If not, you should always do so*:
    http://www.macmaps.com/backup.html
    You never know when a hard drive or a directory might go bad.  Having a bootable clone is a must.
    That link also shows you some tools you can use to recover data.
    If you aren't backed up, try buying those tools first, before attempting to repair the directory.
    Directory issues can be fixed with these tools*:

  • Error message on my Mac Pro Quad Core Dual

    Hello..I'm hoping someone out there can help or advise me.
    I turned on my mac this morning to find it's normal loading screen of grey with the darker grey logo in centre..all normal at this stage. This was followed by a wipe from top to bottom making the background grey a little darker and in the centre the apple logo was replaced by what appeared to be a semi transparent power button symbol with the words. "You need to restart your computer. Hold down the Power button for several seconds or press the restart button"
    I have tried this several times to no avail I have also zapped the P RAM again nothing. Can anyone out there help. I have a Mac Pro Quad Core Dual which is only a few months old and is up to date with its system software.
    I could be so grateful of any assistance.
    Warm regards
    Sophia

    Make an appointment. But in the meantime...
    So from cold boot, you can't do the Command Option P R through 2-3 full reboot cycles (don't let up)?
    Unplug everything and let it sit overnight without power cord or anything. That is the only way to rest the SMC system management controller on the 2008 model, the older model still had a reset button.
    Also learned that the 2008 Macs can all boot AHT if the original OEM installer was used to install the system and the drive has not be completely reformatted and retail OS X used, just holding down "D" on startup. But you have to
    Also, pull all your hard drives. Rule out that, which I have seen a hard drive cause panic on startup, which required disabling journaling and other repairs from Disk Utility and deleting caches, then repair, and finally do Safe Boot (shift key down on startup).
    The only way to test RAM is with TechTool Deluxe or Pro; with Memtest or Rember; and to test some devices is to try using a differnent one, keyboard and mouse included if you have any.
    Last hope: open case, look inside, take the two RAM Riser cards and pull out, check the DIMMs are fully seated.
    If you have 3rd party memory, remove that (would need to before taking in probably).
    Might want to put RAM back to way it shipped with 2 x 1GB and one DIMM on each Riser in slot one. Maybe that will wake this sleeping giant. Changing RAM config use to be one way to clear nvram in the distant past in the time of Arthur.
    PS: it is "odd" to find a BTO 3.2GHz system, and only 2GB. For memory performance, Barefeats found a marked improvement with 8 DIMMs, and of course Mac Pro really needs memory to feed 8 cores and pro apps (2GB would be okay for web and email type use only).

  • Windows – but Which? (What to install on Mac Pro Quad Core?)

    First, apologies in advance if this seems like repetition of a recent topic, but I read through the recent "Vista vs XP" thread and it didn't quite answer my questions.
    Basically, I'm planning on buying a Mac Pro "Quad Core" 2.8 and installing Boot Camp and a Windows OS startup. This puts me into the notoriously tricky area of picking the right version of Windows for my needs, something I haven't really had to deal with in regards to OS X.
    Basically, I'm not looking for something with too many bells and whistles or to much bloatware built into the OS. Also, I'll probably be using some older software/shareware, so backwards compatibility is an issue. On the other hand, I'd like something that works with the Quad Core architecture at its greatest efficiency.
    This means I'm wondering about a couple of features that I may or may not need, and it would be of great help if you folks could point me in the right direction regarding these:
    x64 – Since the Xeon processors in the Mac Pro are 64-bit processors, am I better off with "x64"-compatible versions of Windows (either Windows Vista or x64 versions of XP)? Will this cause problems starting up older programs that may not have been written for x64?
    *Dual Processor Support* – the Quad Core, of course, is a dual processor – will I get better performance from a version of Windows that list "Dual Processor Support" among its features (basically, the "pro", "business", or "ultimate" versions of XP and Vista)?
    If I need those features, I'm probably looking at getting either the x64 version of Windows XP Pro or the Business or Ultimate versions of Vista. However, I'm leaning against Vista based on backwards-compatibility and bloatware issues. That leaves XP Pro x64, but I might go for a more basic version of XP if I find out the x64 or DPS features aren't actually something I need. (The other "extras" in XP Pro don't sound like anything I need.)
    Also, I'm likely to install Parallel Desktop at some point and don't want a version of Windows that would have compatibility problems there, either.
    Anyway, any answers you folks can provide for me in this regard would be very helpful.
    Thanks in advance,
    Peter

    Truth is, I am disappointed in VMware Fusions slow walk toward full support for 64-bit and SP1 but 2.0 beta is getting there. Never used Parallels but best to check their own support forums. They also updated the 1.x version recently.

    You don't need anything first, except I would start with a new hard drive for Vista, don't even do anything with it and pull OS X drive, boot Vista DVD and go from there, just as you would normally. Much easier. After it is installed is when you need Apple BootCamp from your Leopard OEM DVD, install, and then Apple Software Update will take care of 2.1. And install your graphic drivers yourself.
    The problem(s) come with trying to use BootCamp Assist and setting up partitioning, and it only makes it harder - not easier - on Mac Pro (you aren't and don't want to use your OS X boot drive).

    And their Mac Pro area http://forums.macrumors.com which has a lot of Vista talk from Mac Pro owners.
    The only real issues are which graphics card to get today or in next weeks, what drives you are going with and other upgrades like memory (8 x 1GB is actually a good base ideal figure so all DIMM slots are taken up).
    Barefeats has a number of benchmark articles:
    Radeon 3870: http://www.hardmac.com/news/2008-06-16/#8451

    http://eshop.macsales.com/item/Western%20Digital/WD6400AAKS/
    - until the WD "Black" series (I guess Blackbird name or SR71 are already taken) along with 3rd generation of their RE series drives. WD has been popular, reliable, with Mac Pro for last two years. Can't say the same of every vendor. Samsung F1 is also a real winner.
    If you buy only one book to understand and get the most out of OS X: "Mac OS X: The Missing Manual" (Pogue has a Missing Manual Series on most everything, and this is the most popular recommended for Mac OS).
    http://books.slashdot.org/books/08/02/27/1551206.shtml
    I needed 3-4 for Vista before I found "Administrator's Pocket Consultant" and O'Reilly's "Vista Annoyances" are both excellent along with MS Press's "Inside Out."

    Welcome to Apple Support Communities
    Time Machine should be enough to make a backup of your files. Also, it should back up all folders, so open System Preferences > Time Machine > Options, and make sure that there are no folders included in the excluded items list.
    If you want to create a bootable clone of your hard drive, you need to use an app like Carbon Copy Cloner or the Disk Utility's Restore feature > http://pondini.org/OSX/DU7.html

  • Mac Pro 8 core with boot drive cloned from MacBook Pro

    I bought a Mac Pro 8 core and in order to avoid having to reinstall all my stuff, I cloned my OSx (tiger 10.49) partition from my MacBook Pro running vista (installed via bootcamp) to my new MacPro's startup disk. The disk works fine except that the MacPro will not boot to osx unless I use the option key and choose the OSX partition. If i just turn the machine on it doesen't find anything. I think it is looking for windows. What do you think?????
    Also, if i restart from the os x partition on my mac pro it stops just before the lound bong sound and seems to be looking for the dvd drive. Any ideas??

    Well, I've covered this extensively here:
    A Basic Guide for Migrating to Intel-Macs
    If you are migrating a PowerPC system (G3, G4, or G5) to an Intel-Mac be careful what you migrate. Keep in mind that some items that may get transferred will not work on Intel machines and may end up causing your computer's operating system to malfunction.
    Rosetta supports "software that runs on the PowerPC G3 or G4 processor that are built for Mac OS X". This excludes the items that are not universal binaries or simply will not work in Rosetta:
    Classic Environment, and subsequently any Mac OS 9 or earlier applications
    Screensavers written for the PowerPC
    System Preference add-ons
    All Unsanity Haxies
    Browser and other plug-ins
    Contextual Menu Items
    Applications which specifically require the PowerPC G5
    Kernel extensions
    Java applications with JNI (PowerPC) libraries
    See also What Can Be Translated by Rosetta.
    In addition to the above you could also have problems with migrated cache files and/or cache files containing code that is incompatible.
    If you migrate a user folder that contains any of these items, you may find that your Intel-Mac is malfunctioning. It would be wise to take care when migrating your systems from a PowerPC platform to an Intel-Mac platform to assure that you do not migrate these incompatible items.
    If you have problems with applications not working, then completely uninstall said application and reinstall it from scratch. Take great care with Java applications and Java-based Peer-to-Peer applications. Many Java apps will not work on Intel-Macs as they are currently compiled. As of this time Limewire, Cabos, and Acquisition are available as universal binaries. Do not install browser plug-ins such as Flash or Shockwave from downloaded installers unless they are universal binaries. The version of OS X installed on your Intel-Mac comes with special compatible versions of Flash and Shockwave plug-ins for use with your browser.
    The same problem will exist for any hardware drivers such as mouse software unless the drivers have been compiled as universal binaries. For third-party mice the current choices are USB Overdrive or SteerMouse. Contact the developer or manufacturer of your third-party mouse software to find out when a universal binary version will be available.
    Also be careful with some backup utilities and third-party disk repair utilities. Disk Warrior (does not work), TechTool Pro (pre-4.5.1 versions do not work), SuperDuper (newest release works), and Drive Genius (untested) may not work properly on Intel-Macs. The same caution may apply to the many "maintenance" utilities that have not yet been converted to universal binaries.
    Before migrating or installing software on your Intel-Mac check MacFixit's Rosetta Compatibility Index.
    Additional links that will be helpful to new Intel-Mac users:

    Transferring data with Setup Assistant - Migration Assistant FAQ
    Because Migration Assistant isn't the ideal way to migrate from PowerPC to Intel Macs, using Target Disk Mode or copying the critical contents to CD and DVD or an external hard drive will work better when moving from PowerPC to Intel Macs.
    Basically the instructions you should follow are:
    1. Backup your data first. This is vitally important in case you make a mistake or there's some other problem.
    2. Connect a Firewire cable between your old Mac and your new Intel Mac.
    3. Startup your old Mac in Target Disk Mode.
    4. Startup your new Mac for the first time, go through the setup and registration screens, but do NOT migrate data over. Get to your desktop on the new Mac without migrating any new data over.
    4. Copy the following items from your old Mac to the new Mac:
    In your /Home/ folder: Documents, Movies, Music, Pictures, and Sites folders.
    In your /Home/Library/ folder:
    /Home/Library/Application Support/AddressBook (copy the whole folder)
    /Home/Library/Application Support/iCal (copy the whole folder)
    Also in /Home/Library/Application Support (copy whatever else you need including folders for any third-party applications)
    /Home/Library/Keychains (copy the whole folder)
    /Home/Library/Mail (copy the whole folder)
    /Home/Library/Preferences/com.apple.mail.plist (* This is a very important file which contains all email account settings and general mail preferences.)
    /Home/Library/Preferences/ copy any preferences needed for third-party applications
    /Home /Library/iTunes (copy the whole folder)
    /Home /Library/Safari (copy the whole folder)
    If you want cookies:
    /Home/Library/Cookies/Cookies.plist
    /Home/Library/Application Support/WebFoundation/HTTPCookies.plist
    For Entourage users:
    Entourage is in /Home/Documents/Microsoft User Data
    Also in /Home/Library/Preferences/Microsoft
    Credit goes to another forum user for this information.
    If you need to transfer data for other applications please ask the vendor or ask in the Discussions where specific applications store their data.
    5. Once you have transferred what you need restart the new Mac and test to make sure the contents are there for each of the applications.
    Written by Kappy with additional contributions from a brody.
    Not knowing what you did when you migrated from your PB to the MBP, I can't really comment, but it's quite possible it didn't go as well as you think. Numerous users who migrated from PPC Macs to Intel Macs ended up with an Intel Mac that didn't work properly because Intel coded components had been replaced by PPC coded components.
