Can I upgrade to 4GB?

Have a 2006 A1176 U35(last 3) Macmini1,1. I saw this answer in one of the past questions: "Officially this only supports 2GB of memory. However, the ability for this particular machine to handle 4GB of memory is well documented."

It was a different model. Does this apply to mine also?

crucial.com only shows a 2GB kit (1GB x2).

Thanks in advance.

The statement in quotes was made in March 2012 by ABCellars and confirmed by mayer, regarding a 2007 Model Mac Mini. Mine is 2006 and I was hoping either they or someone knew for sure if it can possibly apply to my model since it's just a year earlier.

You have to upgrade the EFI from 1,1 to 2,1. AFTER that, you can install 2 2gb modules. If you do not have 2,1, it will not work. Download 2 files to put in, run the commands, and it should work after a reboot and some interesting screen artifacts. Put in an SSD, and a core 2 duo, and these things really speed up!

Bwilding2000 is correct, but the memory controller can only access slightly more than 3Gb of RAM. So compare you mileage of 3Gb (2+1) or 4Gb(2+2) sticks of RAM.

This did not answer the OP questions, simply giving the specs is not helpful.

Yes it can be done, update the firmware and replace the CPU with an Intel T7200, T7400, T7600.

2GB is it for this model as far as I know. May be a hack for this but never seen one.

the mac mini 2006 and 2007 have the same base, with the factory processor that came with the mac mini 2006 which would be 1.5 or 1.66 would max out at 2gb, you will need the Intel Core 2 Duo 2.33 GHz T7600 processor to be on the safe side that has a max out of 4gb so upgrade the processor upgrade the ram, then what you could do is install 10.6.8 and after that use the work around to install 10.7.5 which can be found on youtube its basically a trick to use a restore image once you have 10.7.5 use mlpostfactor to update it to 10.8.5 then use mlpostfactor for 10.8.5 to update it to 10.9.5 and i think thats the farthest for now (after 10.6.8 all other os installs i mentioned are unofficial upgrades that would run fine based on apples requirements all which can be found on youtube by searching the os number with unsupported mac and you will find it) so to cap up your bringing new life into your mac mini 2006/2007 by upgrading the processor to its max maybe get a 1tb sata drive or any sata ssd, max out the ram to 4gb do all the worarounds untill you get to os 10.9.5 and there your close to up to date

The 2007 model actually support 10.7 officially, since its have a 64bit processor out of box,but 10.8 wont run without workaround since it completely dropped support for 32bit(the efi in 2006 and 2007 model are 32bit)

by

Sorry, there is no workarounds here you can't update the EFI to 64bit and the real issue is the support chips which are 32bit.
