For the 3GB systems, 2GB sticks are cheap enough that it doesn't matter.Īll MacBook generations after the original MacBook1,1 Core Duo 1.83-2GHz one will run OS X 10.7 (the original MacBook will only run 10.6.8). If you're buying RAM for one of these machines, don't buy 2x4GB buy 4GB+2GB instead.

Later generations have a later chipset that's crippled in the same way you can install 8GB, but the machine will only see 6GB. This is a limitation of Intel's supporting chipset. If the Macbook is either the Mid 2007 generation (May-November 2007/MacBook2,1/EMC 2139/2.0 or 2.16GHz Core 2 Duo/Intel GMA950) or the Late 2006 generation (November 2006-May 2007/MacBook2,1/EMC 2121/1.83 or 2.0GHz Core 2 Duo/Intel GMA950), then you may install 4GB of RAM, but the machine will only speak to 3GB of it.

For instance, if you have a "MacMini 2,1" then your system will run Lion. If it says something else then as long as your model number is above those in the table then you should be good to go. If your Mac's model number matches one in the table then you will not be able to run Lion however, if your Mac is not in the table then check the second line of the command output to see if it says "x86_64." If the second line says "x86_64" then you will be able to run OS X 10.7 Lion. This Mac has all the processor capabilities needed to run OS X 10.7 Lion

This should be all that's needed to determine if your Mac will run Lion however, if you need further verification that your computer will work, then you can open the Terminal application (in the /Applications/Utilities/ folder) and follow these steps:Ĭopy and paste the following command to the Terminal, and press Enter:Ĭheck the first line of the output, and see if it matches anything in the following table (models that will not run Lion): If it has both "Core" and "Duo" in the name, then there is a number "2" between those two words (ie, "Core 2 Duo" and not "Core Duo"). It says "Intel" or "Core" somewhere in the name, and does not have "Solo" in its name A quick way to see whether or not your Mac has the appropriate processor is to select "About this Mac" from the Apple menu and look at the "Processor" section, and then see if the following criteria are met: This Mac will not run OS X Lion because it does not have an Intel processor.ĭespite some 2006 Macs not being able to run Lion, others from that year have the capability to run it just fine, with the difference being that the deficient Macs were built with the 32-bit Intel "Core Duo" processors instead of the 64-bit capable "Core 2 Duo," "Xeon," or "Core i3/i5/i7" processors. Unfortunately, this means that some of the early Intel-based Macs will not be able to run Lion when it is released, so if you did purchase one of the first Intel Macs in 2006 (or purchased one second-hand) then you may not be able to install and run OS X 10.7. Apple's newest release of OS X is just around the corner, and part of its advancements is that it will not only be Intel-only as was the case with Snow Leopard, but it will also run exclusively in 64-bit mode and therefore require a 64-bit CPU.
