i want to upgrade from 4gb ram to 8gb on my mac mini early 2009.

For this i need the update 2.1 but it won't let me.

than they told me if i have the boot rom MM31.0081.B06 than i don,t need to,but i have MM31.00AD.B00.

How to change this,or is this okay?

Mac mini, Mac OS X (10.6.7), 4 gb ram Runcore ssd 64gb

    Bumping this, as I am faced with the same challenge.

     

    A salesperson from OWC suggested that the 8GB memory upgrade kit needs an udpate. I started with downloading Mac mini EFI Firmware Update 1.2 which refused to install.

     

    Upon further lookup I noticed that the update is meant for

    Mac mini (Early 2009)

    whilst mine is a Late 2009 one. Here is the info from System Profiler:

     

    Model Identifier:          Macmini3,1

    Boot ROM Version:          MM31.00AD.B00

    SMC Version (system):          1.35f1

     

    Any ideas on how to proceed?

    I'm bumping your bump as well. I have a late 2009 MM as well and in order to fully utilize the 8GB as stated on a few memory sales sites (OWC,Crucial, etc) I need the MM31.0081.B06 (obtained with the EFI 2.1 Firmware upgrade). Some users in this forum as well as mac rumors, and OWC have said that if you have a Late 2009 model Mac Mini that it may have come preinstalled with the latest firmware and even though it shows MM31.00AD.B00 , it is set to use 8GB's fully without issue of slowdown/crashing after what Apple recommends (4GB). The firmware update list does not list the Late 2009 model Mac Mini as needing an update but I still haven't heard a clear answer if we are limited to 4GB/6GB or not.

    FWIW, I have a Late 2009 mini - with 8GB RAM installed (as recommended by Crucial) as follows:

    Seems to work fine to me.
