64 - 32 = 32;
32 - 64 = -32;

The CPU is 64bit. Some MacBooks have 64bit cpu and 32bit EFI. Specs say my MacBook has 64bit CPU and 64bit EFI

By RAM to do mean, size of HDD? Because that is not RAM, RAM is Random Access Memory, whereas HDD is considered storage space, and not Ram, so if you are saying you have 4*GB of space on your HDD, and it is seeing only 3gb out of 4gb.

RAM is the size of memory installed. The HDD is 1 TB
Code:
sudo parted -l | grep Partition
then look for partition table, to see if it is gpt or MBR.[/QUOTE]
$ sudo parted -l | grep Partition

Again, the drive is 1 TB. The Physical Memory installed is 4GB. Apple intentionally limited the OS installed on some 64bit MacBooks to only make 3GB RAM available to the user. The MacBook does not have a BIOS. Since the HDD Mint is on has never had an apple OS on it, is 64bit OS with 64bit EFI I do not understand why it does not see all of the RAM. I am thinking the limitation is set in the Intel chipset.
