Hello,
I have downloaded the Mac OS Sierra but I cannot install it. My MacBook Air fulfill the requirements and have enough space on the disk.
However, when I go to iTunes, I can see that i Have already downloaded the software but I see no button to click and install.
Can someone help me?
Thanks,

To install Sierra, go to the Mac App Store, not to iTunes.
Open the first tab, "Featured" of the App Store, enter "Sierra" into the Search field, and it will show you the download.
Install from there.
Hello,
Thanks for the answer. I went to App Store... when I click on macOS Sierra I can see that I have already downloaded the software... But I cannot install.
I click on it, but nothing happen... Any suggestions?
Thanks
Tomas
If you have definitely downloaded Sierra there should be in your Applications folder an item called Install Sierra.app.
If so check it is 4.78Gbs, make a copy of it for safe keeping, somewhere else on your disc, or on an external drive or USB stick. Double-click the one in your Application folder to start the installation process.
If the item in your Application folder is not 4.78Gbs, then the download has not completed successfully, move it to the trash and delete, check also Launchpad for a Sierra icon, click and hold till it wiggles then click the 'x' to delete.
Restart the Mac relaunch the App Store, try to download again.
DO you have at least OS X 10.7 or a newer system installed?
try to launch the installer from your Applications folder. Look for an installer there named Install macOS Sierra.
Install mac OS Sierra
