OpenCore lets you install macOS Ventura to older Macs — even if Apple doesn't want you to

Each year, Apple introduces a new version of macOS. Certain Macs miss the cut when it does and no longer support the company's latest and greatest software. The open-source OpenCore was launched last summer when macOS Ventura arrived in beta. It has matured since then and now works on more Macs that didn't make the list of supported devices. 

As first noted by 9to5Mac, the OpenCore Legacy Patcher (OCLP) initially allowed older Macs to work with macOS Big Sur and macOS Monterey. The tool has left beta and is based on the same OpenCore bootloader used for Hackintosh. 

It wasn't until recently OCLP worked with macOS Ventura. 

Old is new again

OCLP developers explained to 9to5Mac that Apple has "removed most of the legacy drivers from macOS 13 since this version no longer supports any Macs with Intel CPUs older than the seventh generation. Despite these restrictions, the latest version of OCLP successfully brings extra life to Macs that have been discontinued by Apple."

Our macOS Ventura review confirms that, calling macOS 13 Ventura "an incremental update that's better than Monterey but not as extraordinary as Big Sur," with new features that may not be for everyone. Regardless, it's here and ready for your Mac.

The latest OCLP version works with the following Macs:

  • MacBook 2008 – 2016
  • MacBook Air, 2009 – 2017
  • MacBook Pro, 2008 – 2016
  • Mac mini, 2009 – 2017
  • iMac, 2007 – 2017
  • Mac Pro, 2008 – 2013

Like all open-source software, OCLP has limitations that tend to change as Apple introduces new macOS versions. Therefore, there's a risk associated with installing it on your older Mac. Despite this, it's good to see a tool like this as it allows older Macs to stay up-to-date for a little bit longer, warts and all.   

When it was released last fall, Apple's macOS Ventura bought a small number of new features to Macs, plus various updates. This includes the all-new Stage Manager and Freeform and an updated Continuity Camera feature. The version also brought the mobile Weather and Clock apps to Mac for the first time.
