Hi,

So I bought a mac (2012 one) my lil bro to do his school homework on,
My issue is I can't update the OS cause its an old system
But it says to go on the site to do an update
-So I go
-But It don't work
cause its outdated

Currently It has
OS X Mountain Lion (2012)

Could anyone know how to update it without any issues
Even the app store i can't download few apps as its an outdated OS (e.g Word documents)

(I normally go with Windows cause it avoids all these issues but it was a good deal especially to do his homework)

Help please ♥ if anyone knows.
Thanks
