Did you know you could Upgrade your Unsupported 2009-2015 Mac with OCLP from Big Sur to Monterey from system preferences? YOU CAN, but need to update OpenCore Legacy Patcher first. I'll walk you through the entire process! CHAPTERS BELOW!

OCLP UPDATES 06/22/22:
#1 - You can use the 0.4.6 TUI app to follow along with this video. github.com/dortania/OpenCore-Legacy-Patcher/releases/download/0.4.6/OpenCore-Patcher-TUI.app.zip
#2 - If you have a 2012, 2013 or 2014 Mac with an Intel HD4000 or Kepler based Nvidia GT600 - GT700 graphics, You will need to install the post volume patches!!! Big Sur was fine but Apple removed them from the Monterey Installer.
#3 - If you have a MacBookPro11,3 15" Late 2013 or 2014 and you are stuck at the progress bar after install = boot it with safe mode (hold down shift on boot) then apply the post volume patches. Reboot and you can then install OCLP to your internal hard drive. - github.com/dortania/OpenCore-Legacy-Patcher/issues/522

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 it's really really close. I would not recommend installing on a system that you rely on for work or school. 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 Monterey makes your Mac safer since Apple is no longer fixing security issues on macOS High Sierra and below. Thank you!
