Logic Board Serial Number

I have a question. My MB recently had the logic board replaced. My Serial Number no longer appears in the system profiler. I was just wondering if there is any way to restore the number. Thanx

There is no way to restore serial number in the new logic board replacement because by default apple erase serial number to all logic board replacement.
As service technician there is no sutility to write serial number in the firmware section as of today. Don't know in the future if Apple/intel release the utility.
I've change many logic boards and all of them the serial number is blank in the system profiler. But basically you still have serial number in physical unit which located inside battery bay when you take the battery out you will see the serial number and that's what I use usually to confirm the serial number of the unit.
So if you have macbook make sure that when you get top case replaced the technician move your serial number to new top case.
Hope this help

  • Can you figure out from a G4 logic board serial number what it is?

    Can you figure out from a G4 logic board serial number what it is? for example if it is single or dual processor support, and the speed, i know you can check the case serial number in the apple site, but can't for the life of me figure out the logic board serial number, if any one could help identify what G4 it comes form that would be great, Can you figure out from a G4 logic board serial number what it is?

    Hi, Forrest!
    The Chipmunk site was my first thought when I read the initial post, but although it returns a manufacturing date of the fourth week (Jan) of 2003, I'm not sure that's even accurate, since Chipmunk couldn't return any more info than that.
    I wonder if an Apple Store Genius would/could look it up for him...

  • Logic Boards, Serial Number, and iCloud

    I'm posting this because I want others who run into the same problem to find a solution - I had some difficulty pinpointing why I was having the following difficulties. Hopefully, if you're reading this, my experience will help!
    So, I have two iMacs - one is a mid-2011 model, one is the model before. I upgraded both to Mountain Lion with no difficulties. However, yesterday I began tooling around with iCloud on the newer model, and found that while some iCloud features worked - like Notes and Calendar - others did not, specifically, iWork. I have had no problems syncing files between my iPhone, iPad, and other iMac, so I've been able to retrieve Pages / Keynote / Numbers files with no problems. However, with the mid-2011 model, I was getting just an empty iCloud page.
    I did the basic stuff - ensured that I was signed into iCloud with the correct account, ensured I had fully-updated software, and the like - but still, I was getting no love from iCloud. I searched a few forums and checked out some ~Library folders, but everything looked correct - everything was mirroring my older iMac's setup.
    I initiated a call to Apple and the front-line rep had me create a test admin login to see if there was something wonky with my user file, but the problem persisted. (By the way, talking to a rep on the phone while they initiate a screen sharing program and following their red pointer around was great). The rep quickly bumped me up to a senior person, who investigated more files. And then we hit on the solution, one I didn't think to check out because it was so obvious.
    A few months back this iMac wouldn't boot up, and Apple replaced both the power supply and the logic board. However, the folks at the Genius Bar forgot to "re-serialize" my iMac - the computer was nearly fully functional, but didn't have an internal serial number after the logic board swap. It's like a two-minute step that someone forgot to do.
    I brought the iMac to the Apple Store today and in two minutes they had re-serialized the iMac. When I got home, everything was working as it should - the computer has its original serial number, and iCloud worked perfectly.
    So there you go. If you have some parts of iCloud working, but not others, check that serial number - iCloud uses it for some, but not all, functions. And if you're getting a logic board swap, verify that your iMac has been re-serialized. It'll save you a trip later on.

    Great that you found the solution!
    Make sure you unmark this as a question though.
    Regards!

  • How do I get the logic board serialized?

    I had the logic board replaced a year ago in my iMac. Ive been having some problems sharing maps with my other mobile devices. Someone suggested to check to see if the logic board is serialized. Anyone know how to do this?

    Go to About this Mac in the Apple menu.
    Tap the version number twice. If you see a serial number, it has been set. If not, then take it to an Apple Store or Service center and have them fix it.

  • Logic board serial swap desperately needed

    I just got the logic board replaced on my Mac Pro, and here's my problem: Over the years I purchased hundreds of plugins: VST plugins, Photoshop plugins, Final Cut Pro plugins etc etc, plus tons of apps. There is NO WAY I can spend a week reauthorizing and reserializing all this software without going broke. I absolutely need to replace the new logic board's serial number with the old logic board's serial number. My Mac Pro is from 2007, and I will stop using it as soon as Apple releases the new Mac Pros in 2013. In the meanwhile I still have to pay the bills with this old system and I don't care if the warranty is blown since soon it will just sit there for backwards compatibility (loading old projects in 2015 etc). Can anyone help? I know about Blank Board Serializer, but that only works with Logic Boards with no serial numbers. If I need to I will pay the money and buy another logic board and serialize myself if I need to, but I'm not sure it will work and I don't want to waste another $600.00.
    This isn't fair. I shouldn't be penalized for being honnest and buying all this software. If I had nothing but cracks on my computer, I wouldn't need to change the LB serial number since all the software would just work anyway. So why are the Apple folks and tech support guys so unwillig to help people like me?
    Does anyone have a solution? Is there a way to replace a serial LB number?
    Thanks,
    Jeeve

    Cloning the drive works beautifully, as long as the logic board is the same. Over the years I've used 3 different startup drives on the same computer. CCC has allowed me to save the weeks of re-serializing everything all the time.
    The dufus at the repair shop was lazy and told me he couldn't flash thew new logoic board. Now that I learned it is possible I will  take my system back to the show and make a scene, even if I have to pay for another blank logic board.
    I will contact Apple if this approach doesn't work.
    I never got an answer regarding softraid mirror, but that was before I realized CCC did the trick.
    I understand if it was possible for anyone to flash their logic board and change the serial number there would be mass fraud, but ironically in my case, I need to duplicate the old serial number specifically because all my apps were purchased. If I had cracks this would not be an issue because they would just work with any system;-) If the repair shop doesn't want to do it I'l have to get my money back and go to Apple. I have a few friends who had the same problem and Apple transferred the old serial number to their new logic board.
    In the meanwhile I'm just losing money because I can't work. So annoying!

  • Mid-2010 MacBook Pro 15" 2.8 GHz Logic Board Part Number

    Hi all,
    I have been searching for a few hours trying to find the part number for the logic board one of my MBPs.  I, unfortunately, have the Mid-2010 15" MBP with the bad GPU that results in endless kernel panics.  (I also had the first Pentium chip, the pentium 60 with the floating point error in 1995 too).  I upgraded the MBP to the 2.8 GHz, core i7 (2 core) processor when I ordered it in 2010.
    Anyway, the apple tech guide exploded view does not show the part number for the 2.8 GHz.  It only shows the part numbers for the other 3 configurations - 2.4, 2.53 and 2.66.  I took the cover and discovered my my EEE code is "QAG".
    I have just started trying to figure this issue out (too much time has passed and Apple will charge me to fix).  I want to try and find a replacement logic board and do it myself.   Does anyone have an idea what my part number is for the logic board?  None of the sites I searched have a 2.8 GHz board listed just 2.66.
    An alternative question - In my PC building days, some motherboards were compatible with multiple speeds of main processors.  My computer model number
    MC373LL/A
    is the same as the 2.66GHz model.  Does the 2.66 GHz logic board support the 2.8 core i7 too?  I don't want to screw up and order the wrong part.
    OSX Yosemite is installed.
    Thanks,
    Tony

  • Logic Studio Serial Number Deactivation

    Hi all,
    I have searched the Apple Support Communities and Google to try and get a answer to my question. I have also tried the Apple Online Support (and they suggested that I call their technical department, that are now shut!!!).
    How do I deactivate the serial number on Logic Studio? The reason is that I currently use Mountain Lion OS but it's become a nightmare (constantly freezing and really slowing down), so I am going to go back to Snow Leopard as this was the most stable OS that I have used. I haven't done a time machine back up (and I didn't have Logic when I was using Snow Leopard anyway).
    I want to reinstall Logic Studio once I have installed Snow Leopard onto my Macbook Pro, but am concerned that if I don't deactivate it properly that I will have issues as the serial number will already be allocated. If I was to uninstall the software, would that automatically deactivate the serial number? If so, how can I uninstall it properly (It's not like Adobe software where you have an uninstall folder/option within the applications folder)?
    I have tried the help within the software, but to no avail, and I just want to have Snow Leopard back on my machine as the bugs and lack of stability with Mountain Lion are driving me crazy!
    Many thanks in advance.

    Thanks for the quick reply .
    So... If I was to erase my hard disk and reinstall Snow Leopard, then reinstall Logic, does this pose any issues with the licence? Would I have to make Apple aware, or can I just reinstall Logic onto Snow Leopard, no problems?
    Thanks

  • What do I do if my Logic Studio Serial number was stolen, box and all?

    So, my box for Logic Studio that I've had since 2010 was stolen, as well as my old computer...and external hardrive where the serial number was backed up. Can apple verify it is me via email, social security, anything, or am I just kind of screwed, and can't use the software I paid for?
    Just wondering for a solution, because it has everyhting to do with my lively hood and feeding myself.
    I know that these requests are probably a bane of Apple's, but I am willing to verify my information by whatever means necessary, as I would like to just use the software I have paid for. Is there really no protocol for "everything I owned pertaining to technology got stolen"? Life happens, and so did mine, it was out of my control and I find it fairly unjust that I cannot use anything I used to be able to, now that I finally have a computer again after 2 years.
    Thanks, anything helps I suppose.

    Something that seems to come up time and time again....
    ...is when someone loses their serial number for whatever reason.. the last thing they seem to want to do or try.. is to call Apple
    Whereas, that would be the very first thing I would do...
    Odd huh?

  • I don't have a Logic Pro serial number

    I just purchased Logic Studio V2.1 UPGRADE PRO from a German Apple reseller and I cannot use it because I have to own a previous version of Logic (which makes sense since it's an upgrade).
    I never had a previous version before (that's my mistake). I'm using Logic for the fist time and I don't have an old serial number.
    Is there something I can do? What are my options?
    I really need this software. I'm on a macbook (mid 2007) and I cannot upgrade to OS X Mountain Lion.

    Everything worked out fine. I followed your advice and found an older version of Logic on ebay. I've installed the upgrade.
    Thank you so much for your time Blueberry, I really appreciate it... Bye!!!

  • Logic 9 Serial Number Not Valid

    I recently backed up my computer and did a complete OS reinstall (starting from stratch and not using the old image due to old corruption files). I then decided to manualy copy over Logic Pro 9 files from the backup drive to the new image. I went to open Logic and it asked for my serial number. I typed it in and then it decided to crash on me. Well no big deal, I probably didn't copy all the files. So I deleted as many files as I could find and then proceded to reinstalling Logic 9 from my Logic Studio disc set. Entered name and the serial key during the beggining of the install and it says "Serial Number Not Valid" and asked me to type it again and gives me the same message. After 3 failed attempts, it closes the installation program. I have tripple checked my spelling in the key and have checked forums regarding this problem. I have already attempted to move the ID files in Library/Application Support/ProApps to the desktop; no change. Any input would be nice. Thank you.
    I am running Mavericks 10.9.1 on a MacBook pro 2012.

    Was your copy of Logic Studio 2.0 (the one containing LP9) a full version  or an upgrade version?
    If it was an upgrade version you need to enter your original LP8 serial first.... and then it will ask for your LP9 upgrade serial...
    If it was the full version, contact Apple directly and ask for their assistance.
    http://www.apple.com/contact/
    or use the online webpage to obtain a replacement serial number...
    http://support.apple.com/kb/HT1861?viewlocale=en_US&locale=en_US
    Note: Once you have successfully installed LP9.. you must upgrade LP9 to the latest version 9.1.8 before you run it, via software updates... as you are running Mavericks...

  • Logic Studio Serial Number not accepted for Logic Studio 9 updates

    I just purchased an upgrade from Logic Express to Logic Studio 9. I wanted to download the updates to current versions from http://www.apple.com/logicstudio/download/, but my serial number wasn't accepted on that page. I've checked the numbers (I copied them from the registration dialog just before pressing return - yes, the letters are all caps). Is there anything else I can try? Thanks.

    I've seen lots of people posting about their serial not working yesterday, and experiencing it myself with my own serial.
    http://discussions.apple.com/thread.jspa?threadID=2297318&tstart=0
    I'm guessing their gateway server that authorizes the download by verifying your serial number had "issues" yesterday, probably caused by demand. I'm sure Apple posted the direct download page because of this.

  • Logic Xpress serial number problem ???

    I am trying to reinstall Logic Express 9 from the disk after having to erase my hardrive and revert back to Lion. It will now not accept the serial number and quits. Any thoughts ?

    Make sure you use zeros (0) and not capital O's when you enter your serial number.

  • Logic Pro Serial Number

    My macbook was stolen and I just got a new one. The Time Machine Feature allowed me to put everything onto my new mac and my Logic Pro seems to be installed. When I try to open it, a prompt asks me for a serial number. I have entered the part number from my receipt and every number listed on the barcode sticker on the small box containing my Logic discs, but each gets an invalid number response. I`m out of the U.S. right now and the huge box that the discs and manuals came in is back home. Is that the place I could find the serial number? Is there any way to get the serial number using other identification that I have, my .mac account, purchase receipt, etc?

    Assuming you bought it from apple; just call them and explain. I had a similar problem with license keys except that my CDs simply never came in the post even though my imac came pre-installed and I had ordered it as part of a bundle - in my case it was Logic Express. I called Apple, they took some details, and within about 30 minutes I had one of their support guys email me my license key.
    I was very impressed, no fuss, nothing. Eventually 3 weeks overdue the CDs turned up - can't necessarily blame apple for that as the rest of what I ordered arrived a week early.

  • Logic install serial number

    I am reinstalling LOGIC cause all the sounds didnt install with it. But now its asking for serial number and I bought it from the app store I dont have one or how do I get it?

    If you have only ever had the app store version of Logic 9 then there never was a serial number.
    If it persisits in asking you for a serial you will need to contact Apple to sort it out but be prepared for awkward questions.

  • Logic express serial number

    does anyone know where to find serial # on Logic Express? all I can see is a number on side of box underneath product name- this is on a "sticker". there is no number on printed docs. I saved everything that came in package; want to upgrade to Logic Studio; need to make sure I don't spend $299 and not be able to find serial number. it has been registered- anyway to ask Apple?
    thanks

    In the box that the DVDs came in, there is a little booklet, the size of a CD. On the back cover of this booklet(it's all paper), there are 2 stickers. The bottom sticker has the Support ID number. The top sticker has 2 printed double lines, the same thing written twice.
    The first line should read: LOGIC EXPRESS 7.2 RETAIL, and under that a series of capital letters and numbers in groups of three,,first, with a single capital letter, then a dash, followed by 3 numbers, then a dash, followed by three letters, and it alternates in this fashion, each 3 numbers followed by a dash, then three capital letters. If you include the original single capital letter, it will add up to 28 letters and numbers, separated alternately, numbers, then letters, though it starts with the original single capital letter. This happens 9 times, plus the original letter that starts the group. A dash divides each group of three, starting with the single capital letter, and it's dash. That 28 letter number combination is the serial number.
