Upgrading Older Macs to OSX Sierra: Part 1

February 3, 2017 Comments off


My Mac Tower is finally at a point where it can’t be upgraded. At least that’s what Apple says.

The curious thing is – it can be upgraded – with a little help.

Our MacRecycleClinic guru Lorin Evans found a great website that offers a number of solutions for those of us with older Macs (within reason) that want to use Apple’s latest OS.

The website is pretty plain but has the info you need:

The owner of does ask for a donation if you use his tools to do the deed. But to start – here are the requirements:

-Early-2008 or newer Mac Pro, iMac, or MacBook Pro (MacPro 3,1 and 4,1, iMac 8,1 and 9,1, MacBook Pro 4,1, 5,1 5,2, 5,3, 5,4, and 5,5)
-Late-2008 or newer MacBook Air or Aluminum Unibody MacBook (MacBookAir 2,1, MacBook 5,1)
-Early-2009 or newer Mac Mini or white MacBook (MacMini 3,1, MacBook 5,2)
-Early-2008 or newer Xserve (Xserve 2,1)

Machines that ARE NOT supported:
-2006-2007 Mac Pros, iMacs, MacBook Pros, and Mac Minis (MacPro 1,1 and 2,1, iMac 4,1, 5,1, 5,2, 6,1 and 7,1, MacBook Pro 1,1, 2,1, and 3,1, MacMini 1,1 and 2,1)
The 2007 iMac 7,1 is compatible if the CPU is upgraded to a Penryn-based Core 2 Duo, such as a T9300.
-2006-2008 MacBooks (MacBook 1,1, 2,1 3,1 and 4,1)
-2008 MacBook Air (MacBookAir 1,1)

I have NOT done this upgrade YET but will give it a shot on a backup drive and let you know what happens. In the meantime – give it a try if you’re up to it and let us know how it goes.
