- Jul 01, 2017 This is how to install macOS Sierra on your desktop computer without a mac. Use this tutorial to get your potential hackintosh setup running quickly in only an hours time with a recent generation of Intel CPU/Mobo combo. This guide has been configured to run up to macOS Sierra 10.12.6. Although Apple has hidden Sierra in the App Store following the release of High Sierra, but it can still be.
When you upgrade to macOS Catalina, you get more of everything you love about Mac. Experience dedicated apps for music, TV, and podcasts. Smart new features in the apps you use every day. And Sidecar, which lets you use iPad as a second Mac display. Best of all, upgrading is free and easy.
Download Os X 10.12
Chances are, your Mac can run macOS Catalina.
Mac computers with Metal-capable graphics processors (GPUs) can upgrade to macOS Catalina.
Make sure you’re ready to upgrade.
Before you upgrade, we recommend that you back up your Mac. Then, if your Mac is running OS X Mavericks 10.9 or later, you can upgrade directly to macOS Catalina.
Upgrading is free. And easier than you think.
Upgrading from macOS Mojave?
Go to Software Update in System Preferences to find the macOS Catalina upgrade. Click Upgrade Now and follow the onscreen instructions to begin your upgrade. If you don’t have broadband access, you can upgrade your Mac at any Apple Store.
Upgrading from an older version of macOS?
If you’re running High Sierra (10.13), Sierra (10.12), or El Capitan (10.11), upgrade to macOS Catalina from the App Store. If you’re running Lion (10.7) or Mountain Lion (10.8), you will need to upgrade to El Capitan (10.11) first. If you don’t have broadband access, you can upgrade your Mac at any Apple Store.
