With the OpenCore Legacy Patcher, it is attainable to put in macOS Sequoia on Mac computer systems from way back to 2008. This is find out how to get all the things arrange.
After a collection of developer betas, Apple made macOS Sequoia out there to most of the people. Whereas the replace launched a wide range of new options and helpful enhancements, macOS Sequoia additionally dropped assist for the 2018 and 2019 MacBook Air.
Though the working system nonetheless helps machines way back to the 2017 iMac Pro, many older Mac computer systems cannot run the software program formally.
That is the place a distinguished third-party answer, often called OpenCore Legacy Patcher or OCLP, comes into play. Dortania’s OpenCore Legacy Patcher makes it attainable to run macOS Sequoia on a wide range of unsupported Macs, even together with fashions over a decade outdated.
The patcher makes use of the OpenCore bootloader which can be utilized to “inject and patch knowledge in reminiscence as an alternative of on disk.” In line with the patcher’s GitHub page, for this reason it could actually obtain near-native ranges of efficiency on formally unsupported {hardware}.
OpenCore is what’s often called a customized bootloader, which is loaded earlier than the primary working system. It is an open-source undertaking, out there on acidanthera’s GitHub page. At startup, it lets you choose between a number of working techniques at the moment put in.
OpenCore by itself is often used within the Hackintosh group, the place folks set up macOS on non-Apple PCs. This information, nevertheless, focuses solely on the OpenCore Legacy Patcher, and find out how to use it to put in macOS Sequoia on real, unsupported Mac computer systems. No prior data is critical, other than fundamental familiarity with the macOS working system.
Earlier than upgrading to macOS Sequoia, it is essential to grasp which working techniques and Mac fashions are supported by Dortania’s OpenCore Legacy Patcher.
Which variations of macOS are you able to run with OpenCore Legacy Patcher?
OpenCore Legacy Patcher lets you set up any model from macOS Big Sur to macOS Sequoia on choose unsupported machines. For older variations of macOS, we advocate trying out dosdude1’s Catalina patcher, or NexPostFacto for even older Mac computer systems that may’t formally run macOS Mavericks.
With OCLP, you’ll run launch variations of macOS Sequoia on unsupported {hardware}, this consists of developer betas in addition to public betas. Operating beta variations of macOS is extra dangerous, although, and will trigger you to lose your knowledge if one thing goes flawed.
Which Mac computer systems are able to operating macOS Sequoia via OCLP?
In line with the OpenCore Legacy Patcher GitHub page, the software program makes it attainable to run macOS Sequoia on the next unsupported Mac computer systems:

Late 2008 to 2017 11-inch and 13-inch MacBook Airs
Early 2008 to 2017 13-inch, 15-inch and 17-inch MacBook Execs
Early 2009 to 2014 Mac minis
Mid 2007* to 2017 20-inch to 27-inch iMacs
Early 2008 to 2013 Mac Execs
Early 2009 to 2009 XServe machines
Word that 2007 iMac fashions require an upgraded CPU to be used with OpenCore Legacy Patcher. These machines might be upgraded with both a T9300 2.5 GHz Intel Core 2 Duo or a T9500 2.6 GHz Intel Core 2 Duo.
For Early 2009 via Mid 2011 iMacs, in addition to Early 2008 and 2009 Xserve fashions, an improve to a Steel-compatible GPU is beneficial for higher graphics efficiency and graphics acceleration. Steel is Apple’s GPU-accelerated graphics and compute framework, used all through newer variations of macOS.
Pre-2012 Macs usually lack a Steel-compatible GPU by default, however some iMac and XServe machines might be upgraded with newer graphics playing cards. OCLP nonetheless helps non-Steel Macs, although, however customers might expertise efficiency points or Steel-related issues, such because the Pictures app failing to work correctly.
On the time of writing, 2018 and 2019 MacBook Air fashions can’t be up to date to macOS Sequoia with OpenCore Legacy Patcher, on account of a problem with the T2 safety chip present in these computer systems. In consequence, these machines at the moment can’t be upgraded previous macOS Sonoma.

Many older Mac fashions supported by OpenCore Legacy Patcher don’t characteristic a T2 safety chip, making iPhone Mirroring unattainable on these computer systems.
2018 and 2019 MacBook Air fashions characteristic the T2 safety chip required for iPhone Mirroring, however macOS Sequoia can’t be put in on these machines with OpenCore Legacy Patcher. Apple doesn’t provide macOS Sequoia assist for these computer systems both.
Most Pre-2012 Macs lack a Steel-compatible graphics card. Merely put, Steel is a hardware-specific graphics acceleration framework that is used all through macOS.
Macs with out a Steel-compatible GPU will expertise some points on macOS Sequoia.
OpenCore Legacy Patcher’s builders have created root patches particularly for non-Steel Macs, that means that customers of older Mac computer systems will nonetheless be capable to use macOS Sequoia with out main issues.
That being mentioned, although, non-Steel Macs can nonetheless expertise issues with options equivalent to Tiled home windows and Stage Supervisor. Apps equivalent to Maps, Pictures, and Climate additionally don’t work correctly on non-Steel machines operating macOS Sequoia. Macs with out a Steel-capable GPU may expertise points with the brand new wallpapers present in macOS Sequoia.

Coming from the builders themselves, the web page has an in depth information, together with quite a few helpful sources. It additionally particulars the invididual points that have an effect on particular unsupported Mac fashions, and lists potential workarounds for a few of them.
For individuals who desire a information in video type, Mr. Macintosh has a devoted video on putting in macOS Sequoia and OpenCore Legacy Patcher on unsupported Macs. Anson Alexander additionally has an analogous video on his channel.
Whereas there are many helpful sources and movies detailing the set up course of, there are different components that must be taken under consideration. Earlier than upgrading, you will wish to take into account all the things you’d get with macOS Sequoia, and the way it could affect your Mac in the long term.
Is macOS Sequoia value operating on unsupported Macs?
By putting in macOS Sequoia on an unsupported Mac, you are successfully extending its lifespan nicely into the close to future. Over time, an growing variety of third-party functions will seemingly require macOS Sequoia to run.
