Serial Number Unavailable

Recommended Posts

Hello again!


I'm having a problem with my serial number. I have a SMBIOS that Chameleon uses for my system, but the serial doesn't get processed (or something). Whenever I open the Mac App Store and try to login, I get a message saying that my system can't be identified. I open About This Mac, and find that my serial number is listed as "Unavailable". I have a verified serial number (unused).


What may I do to make Chameleon inject it?

Did you verify your SMBIOS plist with Chameleon Wizard? It looks as if the file does not actually contain a serial number. I guess you have the same reported info in your SysProfiler.

Here we are...


The attachment system doesn't allow me to upload this type of file, so I will upload it to DropBox and send it to you.


Thank you!


EDIT: I forgot that I could insert its contents into the post...

You must zip files to attach them...


Coming back to your SMBios, you should not have to specify those CPU/clock speeds in the plist, nor the RAM speed (is it really [email protected] by the way, not 1600MHz?), all being incorrectly specified as far as I can see... Those values should be entered as numbers expressed in MHz, not text with "GHz" inside, i.e. "2500" for max/nominal CPU speed, "3500" for external clock (this is the bus speed (like old FSB) not CPU max/turbo speed like you seem to believe) or "800" ("1600"?) for RAM speed. Please note this information is purely cosmetic and has no incidence on system behaviour or operation.


If I take the example of a computer with a good old Intel Core2Duo T9300 2.5GHz CPU (LFM/HFM/IDA speed 1.2/2.5/2.7GHz, FSB 800MHz) and PC2-5300 RAM modules (DDR2-667), the SMBIOS data could be manually entered as follows:

  • max CPU speed: 2500
  • external clock: 800
  • memory type: DDR2
  • memory speed: 667


Where is your plist located and under which name (full extension included)? You sent me a file called SMBios.plist.txt and that won't work, it must be called SMBios.plist (or smbios.plist) and placed in /Extra. Try the attached file.



What's the reason for choosing the MacBookPro Retina (MBP10,1) profile by the way?

I apologize for the attachment confusion.


As for the memory speed, it IS 800 megahertz (PC3-12800). I have verified all of this information, for the record. I had it all placed in Clover when I last used it, and CPU (APU for me) speeds along with memory speeds were listed in the megahertz unit of frequency. Yes, I know, it had no effect on system operation.


My System Management BIOS property list's path is /Extra/SMBios.plist, where Chameleon wants me to place it. I uploaded this to DropBox in the correct format, however, I do not know what added the .txt extension to it.


Thank you again!

Technically, you are absolutely correct in the sense that PC3-12800 does indeed operate at a clock rate/bandwidth of 800MHz just like PC2-6400 (DDR2-800) operates at 400MHz or PC2-5300 (DDR2-667) operates at 333MHz. However, that is not how DDR RAM is dubbed in "marketing" terms. PC3-12800 = DDR3-1600 and in the SMBIOS context this is meant to be reflected as 1600 "MT/s", even though OS X uses the term "MHz". You may consider this artificial/incorrect doubling of memory speed but DDR means Double Data Rate and a confusion between MT/s and MHz (you may call it an abuse of language) has just generally settled in... 




Even respectable distributors like Crucial refer to speed in MHz rather than MT/s most of the time...




Anyway, any Apple Mac or Hackintosh with XX Go of DDRz-YYY RAM will/should report "XX GB YYY MHz DDRz" in "About This Mac". YYY is what the SMBIOS memory speed field will address.


For instance, my Dell E6440 has 8Go of DDR3-1600 RAM in the form of 2 x PC3L-12800S SODIMMs. OS X reports RAM as follows:

Thank you! I will read the article that you have linked from Wikipedia.


As for why I chose the MacBookProRetina10,1 profile, I wanted to come as close as possible to my system specs and form. I may have focused a bit too much on processor speed. Do you have a better system profile in mind, or will this work?

CPU speed really is not a valid criteria at all; it's much better to choose by CPU family closeness and/or GPU closeness. In your case, you have an AMD CPU with an unsupported GPU... I'm not familiar at all with recent AMD CPUs but assuming your APU is say a direct competitor of an Intel Haswell, choose MacBookAir6,2 to begin with but you may also opt MacBookPro11,1 (that's what I use on my Dell E6440 as it gives me an extra intermediary CPU multiplier). If your APU is more comparable to Sandy or Ivy Bridge, choose a corresponding model in the list offered by the Cham Wizard.
