If you own a 2011 MacBook Pro and are looking to upgrade from Mac OS 10 Lion to Mac OS 10 High Sierra, you may be wondering if it’s as simple as going to the Mac App Store and searching for High Sierra. Unfortunately, it’s not. When you search for High Sierra on the App Store, you won’t find any results because Apple only keeps the latest version of Mac OS on the App Store, which is Catalina.
To get High Sierra, you need to go to the link provided in the video description below and click on the “Download High Sierra” link. This will take you to the Mac App Store where you can then download High Sierra. But, there’s another problem. When you get to the App Store and have High Sierra ready to download, you’ll get a message that says the update requires Mac OS version 10.8 or later. This is strange because we know that the 2011 model should support High Sierra.
There is actually an intermediate step that you have to complete before you install High Sierra, and the best way to do that is to upgrade to Mac OS 10 L Capitan first. To do this, click on the “Download” link provided in the video description. This will start a download called “Install Mac OS 10.dmg” which is a pretty good size file. Once the download is complete, open the file and double click on “Install Mac OS 10.package”. This will open the installer window.
From there, hit “Continue”, then “Agree”, and “Agree” again. It will install on your Macintosh HD. If prompted, enter your password to let it install. This will install the installer, which should appear in the Launchpad. Once it’s completed, you can close it and eject it from the Finder window.
Now, you can click on the installer in Launchpad to begin the El Capitan installation. Hit “Continue” and “Agree” again, then install it on your Macintosh HD. It will ask for your password and then begin installing. This will take a while, and your computer will restart automatically. Once it’s done, you’ll be running El Capitan.
Now that you’re running El Capitan, you can upgrade to High Sierra. Click on the link provided in the video description to download High Sierra. It will automatically launch the App Store for you, where you can download High Sierra. Click the “Download” button, and it will start to download. Once it’s downloaded, you can go through the install wizard for High Sierra.
Hit “Continue”, “Agree”, and “Install”. You’ll need to enter your password, and then the installation will begin. This is a completely automatic installation, so sit back and relax while it installs. High Sierra takes a little longer to install than El Capitan, but once it’s done, you’ll be good to go.
In conclusion, if you’re running old software like Lion and want to get to the latest version of High Sierra, it is possible, but you have to do that intermediate step of installing El Capitan. It’s kind of weird that you have to do this, but that’s just how Apple does it. The El Capitan installation takes about 30 minutes, and High Sierra is a little longer. Once it’s all done, you’ll be sitting on the High Sierra desktop.
