![Big Sur on older Macs [2008-2013] ULTIMATE GUIDE! OpenCore Legacy Patcher for Unsupported Macs](https://i.ytimg.com/vi/znlhI6f7x1Q/mqdefault.jpg "Big Sur on older Macs [2008-2013] ULTIMATE GUIDE! OpenCore Legacy Patcher for Unsupported Macs
You can Install macOS Big Sur on your 2008-2013 Unsupported Mac with this ULTIMATE GUIDE!!! I will show you how to use OpenCore Legacy Patcher to install on 3 different Macs - 2013 Macbook Pro 15, 2011 MacBook Pro 15 and a 2010 Mac Pro. I will show you how to do a erase install, upgrade and a dual boot system! You can then update to the latest version of macOS Big Sur 11.6 using system preferences with native Software Updates!
UPDATES! 6/22/22
#1 - You can use the 0.4.6 TUI app to follow along. https://github.com/dortania/OpenCore-Legacy-Patcher/releases/download/0.4.6/OpenCore-Patcher-TUI.app.zip
#2 - OCLP TUI Versions 0.2.5 and newer have a new menu system. The look is a little different from the 0.2.4 and below (the version I am using in this video). If you want to see the newer settings in action you can check out my Monterey video https://www.youtube.com/watch?v huRykhjs6g
#3 - Starting with OpenCore Legacy patcher version 0.2.5 and newer AMFI is handled by the patcher. On some models it can be enable but on others it needs to be disabled.
I wanted to thank both Mykola Grymalyuk (khronokernel) & Dhinak G (dhinakg) for your work on OpenCore (plus everyone else who contributed). You both did an amazing job on this patcher. OpenCore will save thousands of Macs from the recycler!

DISCLAIMER: Please understand that installing macOS Big Sur on your unsupported Mac is a best effort by the community. A ton of work went into getting the patcher to work! Some things might not work exactly right but its really close. ALWAYS BACKUP YOUR FILES FIRST BEFORE YOU UPGRADE! The good news is that you are getting the latest security fixes from Apple. Some might argue that upgrading to Patched Big Sur makes your Mac safer since Apple is no longer fixing security issues on macOS High Sierra and below. Thanks
