  1. Jun 16, 2021 If you’re unsure what version of macOS you have, you can check your macOS or OS X version by clicking the Apple icon at the top-left corner of Mac’s screen, then select About This Mac. In the Overview tab, look at the Mac model year below the OS version number.

With all software listings, note that the following nomenclature normally means compatibility is limited to the following:


10.6 and up = 10.6 and 10.6.1.


10.6.x and up = 10.6, 10.6.1, 10.6.2

Most of these machines have newer hardware that was never available for Mac OS 9, therefore there are missing drivers and system components - not all devices will work. The most common issues are with unsupported sound cards, video cards, Bluetooth, and Airport cards. The maximum version of Mac OS X, OS X, or macOS supported by each G3 and later Mac follows. For complete specs on a particular system, click the name of the Mac. For all Macs that are compatible with a specifc maximum supported version of Mac OS X - courtesy of EveryMac.com's Ultimate Mac Sort - click the OS of interest.


10.6 to 10.6.8 = all versions of 10.6 are supported.


Mac OS = could mean just Mac OS 9, or 1 through 8 and no Mac OS X.


Mac OS X = could just mean 10.0, or it could mean all PowerPC Macs running 10.0, or all versions of Mac OS X.


Mac OS X PPC = means G3, G4, and G5s may support it with 10.0 through 10.5.8, but no certainty exists which ones. Mac OS X Intel = means 10.4.4 through 10.9.1 are potentially supported on Intel Macs, but no certainty exists as to which ones.


Classic = Mac OS supported typically 9.1 to 9.2.2 within Mac OS X without rebooting into 9 via Startup Disk System Preference or Startup manager, but no certainty as to which versions of 9 are supported unless stated. Intel Macs are not supported at all. Mac OS X 10.5 not supported. Classic is controlled via Apple menu -> System Preferences -> Classic, the Classic Dock toolbar, or menubar icon. Within Mac OS X, you'll know if you are in Classic when the name of the Application appears in the upper right corner of the menubar, instead of the between the Apple menu and the File menu.


Booting into Mac OS 9: Only supported through Apple menu -> System Preferences -> Startup Disk machines that show the Mac OS 9 system folder. All G3 and G4 prior to and including iBook G3, and PowerMac G4 without Firewire 800 are supported. This image:


shows where Firewire 800 would be on a PowerMac G4, if it is there. The iBook G4, PowerMac G4 with Firewire 800, Powerbook G4 with ports on the side as opposed to the rear behind the hinges, iMac G4 800 Mhz with combo drive, iMac 1 Ghz and up, and eMac G4 certain 1 Ghz models and higher do not support it.

Mac Os Unsupported


Rosetta - supports PowerPC Mac OS X applications on Intel Macs through 10.6.8, but not above, and no certainty as to which ones.


Universal - Applications which run on PowerPC and Intel Macs. These may be found on 10.4.4 and higher versions of Mac OS X, though no certainty as to which

version is supported unless actually stated in the requirements.

Last year’s most significant WWDC event was a new version of macOS, Big Sur, and the announcement of the move to its own ARM processors. In macOS 11 (instead of the expected 10.16), Apple has massively redesigned the interface, added many new features and tools to move to new application architecture. We tell you which Mac models will be able to install macOS Big Sur.

The “Today” widgets in MacOS Big Sur are similar to the updated widgets in iOS 14. Other changes include an updated widget-enabled notification center, significantly improved messages, a powerful Safari upgrade, and more. Apple will release macOS Big Sur for all compatible Macs this fall.

Which Mac models will be supported by macOS Big Sur?

Supported devices that will receive MacOS Big Sur support:

  • MacBook 2015 and newer
  • MacBook Air 2013 and newer
  • MacBook Pro 2013 and newer
  • Mac mini 2014 and newer
  • iMac 2014 and newer
  • iMac Pro 2017 and newer
  • Mac Pro 2013 and newer

Because macOS Big Sur is a major update, Apple has given up support for several outdated Macs. The transition to new Apple Silicon processors will take several years, so the current Macs running at Intel will be updated for a long time.

Apple also unveiled updated iOS, iPadOS, and watchOS. The new WatchOS 7 won’t support the Apple Watch Series 1 and 2, but iPhone and iPad users who support iOS and iPadOS 13 will be able to upgrade their devices to the next generation of OS seamlessly.

You can also use the Disk Utility if you are planning to format your drive and create a new partition and continue with the installation.

The installation may take several hours. In our case, it sometimes looked as if the installer had flown out during the upgrade. In this case, you should wait, as the installation is usually still ongoing. Over time, better ways to upgrade the machine can be found. Currently, the safest approach is to upgrade with a USB boot.

After the installation is complete, you will see that your Wi-fi is not working. So go to applications and search for Patcher file.
