Acabei de instalar MacOS Sierra, que é 10.12
Mas nada mudou que ainda é OS X 10.9.5
Então, como atualizar para a Sierra
i just installed macOS SIERRA which is 10.12
but nothing has changed it's still OS X 10.9.5
so how to upgrade to sierra
You first have to install El captain X You might not can install the sierra if you ox system was made in the early part of 2009
I have a 2008 iMac. Its running 10.9.5. Because its an intel machine, the later operating systems thats are not intel it wont upgrade. Its as far as you can go. I just had to throw out a Canon MP810 2008, as the latest driver won't run the canon printer utilities. My next computer will be a win10 laptop. I am so over the compatibility issues. Apple was great with backwards compatibility. Not now. Still its served me well for 10 years so I shouldn't complain.
