Apple Introduces iPhone 8 Logic Board Repair Program Posted by Evan Selleck on Aug 31, 2018 in Apple News, iPhone 8, News Apple has its fair share of repair programs for its various devices, all in an effort to clamp down on lingering issues. Macbook Air Logic Boards. Home > Mac Parts by Categories > Mac Logic Boards > Macbook Air Logic Boards. Manufacturer Part Number: 661-4644. Price: $92.00. Logic Board MacBook Air 13' Mid 2011 1.8 GHz CTO MC965LL 820-3023 A1369. Manufacturer Part Number: 661-6101.
Over the multitude of years of service, my 2009 Mac Pro has endured many supported and unsupported software updates, OS upgrades, hardware upgrades, firmware upgrades, re-installs, wipes, Boot Camp installs, boot loader changes, and so on and so on. Over that time and over those many changes, at some point, my logic board lost its marbles and simply 'forgot' its serial number.
Here's how to get your Mac to 'remember' its serial number once more!. The problem with not having a serial number For quite some time I had no issues with my Mac not knowing its serial number or revision (year of manufacture).
Everything worked fine. I could install programs, log into the App store, iMessage friends and colleagues, and everything else needed in my Mac environment. However, a time came after a certain update or upgrade (I can't remember which, since for the most part, everything still just worked) certain services like iMessage and FaceTime would no longer allow me to log in to their services. Strangely some other services logged in just fine. Words of warning You really shouldn't do this fix. But if you are insisting on getting it done there are a few caveats before delving into this fix.
First, you not only need a valid serial number, but you need a valid serial number for the hardware you will be performing it on. The serial number CAN'T be transferred between machines. Therefore this fix is truly for your genuine Apple hardware that has lost it's serial number along the way on its logic board.
You'll be using the same serial number that the computer originally had when you first purchased it. Second, there is no room for error. You only get one chance at inputting the proper serial number during the 'write' phase of the how to. If you mistype any part of it, you'll likely end up with a non-bootable system. DO NOT PERFORM THIS FIX IF YOU CANNOT LIVE WITH A NON-WORKING MACHINE. Third, and most importantly, I'll be suggesting (but not providing) software that may or may not be for Apple's internal use only.
I do not know the legality of having access to this software or using this software. Do not use this software if you worry about the copyright or legal issues that may or may not be involved with running said software. Fourth, If this doesn't work for you and you get a non-functional system. Don't blame us. I told you to not perform this fix.
Fifth, if you have an Apple warranty that's still valid, call Apple to fix the serial number issue. Don't use this method. This will likely void any valid warranty.
Finally, don't use this fix. Get your serial number Getting your serial number should be a straight forward affair. When you buy your Apple for Apple.com, you'll get a receipt via email with your serial number on it.
The box that your Mac came in will also have a serial number on a card within the box. You Mac itself, will have the same serial number somewhere either on, in, in back of, or under its casing. There is literally very little excuse for you to not have access to your serial number. Get a USB key For this to work, you'll need to be able to boot off of a secondary device such as a USB. The files are very small so nearly any USB key will work.
I used the from Amazon for $15 in my example. Get the software The software I'm using but am not providing is called the Blank Board Serializer. The fix. Format the USB drive with with the FAT filesystem. Unpack the Blank Board Serializer program to your disk. Using Disk Utility, Restore the unpacked dmg file to your USB drive. Click Done.
Shutdown your Mac. Reboot your Mac whilst holding the option key on your keyboard. You'll be presented with multiple boot devices, choose the EFI USB key. Click to Accept the usage agreement. Enter your Serial Number WITHOUT ERRORS. Truly make certain there are no errors here. Remember that Zeros (0) and 'O's' look very similar.
Click Enter. Click Yes for each following prompt. Click Proceed. Click Restart. Final comments Why was I able to log in to all of my services before the unknown update is anybody's guess.
Is it because Apple wants only genuine Apple computers accessing their networks? If so then why would some iCloud services work whilst others didn't? In any case, Once a valid serial number was re-installed on my logic board, everything worked as seamlessly and as beautifully as expected. What about you? Are you living with no serial number? How has it affected you? Let us know in the comments!
Hi, I have question if someone reply and guide, it would be highly appreciated. Seven month before I purchased new MacBook Pro 17' from Dubai apple store. After around 3 month later, some display problem and I contact to apple store, I asked for replacement but they changed the mother board and gave me back with working condition. Now I have new serial number of my MacBook Pro. Now I have DVD drive problem, DVD and cd reading is ok but when I am inserting empty DVD to write, drive doesn't accept dvd and comes out. Other side, cd writing is ok, only dvd writing problem. Again I contact to apple store and they checked my system and ordered new drive.
And now a days waiting for replacement drive. My MacBook Pro serial number is changed, not same as I purchased, is this ok or I should ask for replacement my MacBook pro.? Please help or guide me what should I do? Hi Imran, Are we referring to the MAC address or the actual serial number? If we're referring to the MAC address then absolutely to be expected.

If we're referring to the serial number that's being displayed in System Profiler (and read off the MLB) then that's absolutely not to be expected. I had my iMac's logic board replaced by one of Applecare's onsite technicians a few months back and the part comes with a 'blank' serial number. That is to say. After he performed the installation and verified that the part was functioning correctly and my issue resolved he inserted a CD, started up off the CD and 'zapped' my logic board with the serial number of my computer. He stated to me that this was the process of all the logic boards that he services (including portable computers at his repair shop). Apple gives him some CD to make this happen, so it's easier for the customer to read off their serial number then to look for it on the machine. With that being said, you shouldn't have a 'new' serial number.
If anything it'd be blank. So based on my personal experience and the feedback from the repair technician I don't think the serial number is correct.
I certainly don't think asking for a new machine is the answer, however, more just for them to properly identify your hardware serial number to the logic board. As has been mentioned, they 'can' burn the correct serial number into the ROM of the new board. From what I understand, this can only be done once. The most common thing I have seen is for the to just skip this. But I have seen reports of people having the wrong number. Provided you have had your service done by Apple (as you have indicated), it shouldn't be an issue regardless. They'll have a record of it.
Just to put your mind at rest however, just give them a call and explain your situation to them and they should be able to let you know for sure. Apple Footer.
