Os For Macbook Pro 2009
I am currently running Lion 10.7.5 on my early 2011 Macbook Pro. I mainly wish to upgrade because the browser I use (Firefox) does not support Lion anymore (otherwise everything else works fine although a bit slowly).
I have done a bit of research but I am still unsure which OS I should update to (I only have 4Go of RAM).
It seems that currently only Sierra is available for download ? Is there any way I can upgrade to one of the older OS (I don't mind paying for it) and which one do you think would be best for my Mac ?
Thanks a lot
MacBook Pro, Mac OS X (10.7.5)
