Of course it is recommended you upgrade your Mac to the maximum amount of RAM and replace your hard drive with a solid state drive (SSD). This will make your machine run a lot smoother regardless of which OS you decide to install. And now for the step-by-step guide on installing macOS 10.15 Catalina on your unsupported Mac!

Carbon Copy Cloner requires macOS. CCC will not run on Windows.

Carbon Copy Cloner 5 is the latest version available. Users running Yosemite (10.10), El Capitan (10.11), Sierra (10.12), High Sierra (10.13), Mojave (10.14), or Catalina (10.15) should use this version of CCC. If you are having trouble downloading CCC from the link above, try this alternate download location.

Upgrading from CCC 4? CCC 5 is a paid upgrade. CCC 4 Personal and Household licenses purchased prior to May 22, 2017 are eligible for upgrade pricing. When you open CCC 5, it will automatically retrieve your new license or an upgrade coupon that you can use to purchase CCC 5 at 50% off. CCC 4 licenses purchased on or after May 22, 2017 are eligible for a free CCC 5 upgrade license.

2. 2009 Mac Pro: Once it's flashed to MacPro5,1 firmware, it should be equivalent to a 2010/2012 Mac Pro. (As with those, you will want to upgrade to a Mojave-compatible graphics card.) However, note that some people have had their flashed MacPro4,1s enter boot loops during installation.

Upgrade Unsupported Mac To Mojave Os

CCC 4 and Mojave+: CCC 4 is qualified up to macOS High Sierra. CCC 4 license holders are welcome to continue using CCC 4 on later OSes with the understanding that this is an untested and unsupported configuration. CCC 5 is fully qualified on macOS Mojave and offers extensive support for APFS, including support for point-in-time restores via APFS filesystem snapshots.
