I received another customer question on a third party website, where I earn supplemental income answering computer and technology related questions. This is the customers question quoted verbatim:
I have a MacBook Pro that was purchased in 2012. It current operating system is OS X 10.10.5. I installed Turbo Tax 2017 and I got a message saying that I must install OSX10.11 to use this product.How do I download OSX10.11? How much will this cost? Can I do this online?
This individual installed TurboTax 2017 tax software onto their Apple Macintosh Book Professional computer. This program will not work unless their Apple Macintosh Book Professional computer is upgraded to Apple Macintosh operating system ten 10.11, which is also known as El Capitan. Newer versions of Turbotax tax software, for example 2017 versions, now require Apple Macintosh operating system 10.11 or newer.
This Apple Macintosh operating system 10.11 is known as El Capitan. In order to upgrade your Apple Macintosh computer operating system, you must now have an Apple identification. This customer could not install Apple Macintosh operating system El Capitan.
However, they were able to install Apple Macintosh operating system High Sierra and thus I have included instructions for upgrading your Apple Macintosh operating system Yosemite to High Sierra. If you have installed Apple Macintosh operating system High Sierra before, then all you have to do is browse to the “Apple Store” on your Apple Macintosh computer. You will need to login with your Apple identification.
You can click on the “Purchases” tab. A list of all your previous purchases will populate. Apple considers operating system upgrades as purchases. Then you will want to select “High Sierra”. Then you can click on “Download”.
Depending on the speed of your Internet connection, this download can take possibly hours to complete. If you have not installed Apple Macintosh operating system 10.13 High Sierra before, you will need to download High Sierra from this alternative Apple Store download link. You will need to access this link from your Apple Macintosh computer.
Once Apple Macintosh operating system High Sierra completely downloads, then the installation will open. You will need to enter your Apple Macintosh operating system password and accept some of the terms of conditions. You can keep clicking “Next” until you come across a “Restart” window.
Then you will want to click on “Restart” and your Apple Macintosh computer will reboot and begun upgrading from Apple Macintosh operating system 10.10.5 Yosemite to Apple Macintosh operating system 10.13 High Sierra. You can click on the Apple icon and select “About this MAC” to verify your operating system. You should see Apple Macintosh operating system 10.11 populated or a different version.
Here is a bonus tip that I will share with you. Now that you have successfully upgraded your Apple Macintosh computer operating system to High Sierra, you can upgrade other Apple Macintosh computers to High Sierra by just logging into the Apple store with your Apple identification and clicking on that “Purchases” tab. You can then download Apple Macintosh operating system High Sierra from this tab.
Finally, if you are having problems upgrading to Apple Macintosh operating system High Sierra, it might be because your Apple Macintosh hardware is not compatible. You will want to verify whether or not your Apple Macintosh computer hardware is compatible or not. If your Apple Macintosh computer hardware is compatible with the Apple Macintosh computer operating system, then obviously you will be able to download and install it.
