Hello,

I am trying to change my Mac's (not the wireless or ethernet) serial #. Will this require seom firmware modding of some sort?

Thanks in advance!

Correct be if Im wrong, but isn't the serial number the Mother Boards serial number as well? if so, then it can't be changed without getting a new MB

I am in the same boat. My computer was just sent back from AppleCare and they finally replaced my defective logic board but now I have "NO" serial number of any kind.

I have been fighting with them to fix that or let me fix it, and here is what I have found.

The serial number is stored in NVRAM in OpenFirmware. Data is written to the NVRAM memory chip by going to the OpenFirmware prompt, entering your new commands and then "nv-update".

The problem is finding a command (if one actually exists in OF instead of needing to write into a config file and then run it)

We need to find a really great Linux Kernel Developer with strong experience with Proc to find out where it looks up the system serial number from.

This is the problem we are trying to get around. Change the serial # without having to change the motherboard.

I was recently reading some other posts where it was reported that the serial changed when they replaced their hard-drive. Could this be possible? Is it possible that the serial is a combination of hardware serial numbers? Can anyone confirm this? Or is it just a number assigned to a motherboard NVRAM?

I recently had my logic board replaced,

When I got my MacBook back, some silly repair-centre person had left a CD in the drive called "SetSysSerSum-3T100". The readme file shows it is a utility that when booted into, allows you to, easily with a GUI, change the serial number of any intel mac!

Kinda wary of posting the dmg here, but if there's interest..!

Send that to me....

Ok you can now find the DMG here: http://www.mediafire.com/?4yeeombyqky

Burn it using disk utility to make it bootable.

Note that all files except the readme are hidden, they are still there.

The CD itself looks nothing mass-produced, it's just a standard branded CD-R with scrawled writing on it!

thank you very much

[McSkywalker]

Wow thanks

[Titan_sss]

Thanks for the file. Question though...

I'm new to macs (so don't start kickin'), and I am just wondering what would be the consequences of using the program posted. I mean, wouldn't I have to change anything else (such as the airport serial, mac adress, even some other hardware...) or this prog just changes the serial and everything else remains the same. Has anybody tried it? Is it working and how?

cheers!

send a ppc mac in and hope for the stupid employee that leaves the disk in the comp

OMG. I am so happy I found this thread! I have been looking for the solution for almost 6 months now. It worked perfectly now I don't have "SystemSeumb"

does this disk can work with mbp? I use it to restore my original serial number with mbp, mbp cannot boot from the disk.

[BigAdama]

Is there any update on a PPC version?

Does anyone know if this dmg will still change the serial number on the newest macbook pro's ? The one's with the 2.4 ghz processor? I have a 17 inch model and when I press and hold the D key when booting, it will not boot from the cd. I've tried putting in other bootable cd's and holding ALT/option and that cd shows up (bootable Leopard install disc). I also want to mention that I had an older version Macbook Pro (2.33ghz) and it ran the cd just fine and I was able to change the SN. I'm just kind of wondering if it's a hardware issue, or firmware....and if anyone else has had any luck changing a serial number on the newest macbook pros. Thanks!

Maybe a stupid question but What is the point of changing the serial number of your mac?

[The iMan]

Maybe its hot or your logic board was replaced

[DigitalK]

are there different versions of this software? It just black screens on my mac pro. I bought in December.
