Good evening everyone, thanks to all who contribute to this site and are so knowledgable. I recently purchased an early 2014 MBA 11" and it is running OSX 10.9.5 Mavericks...I want to install Big Sur but strangely most of the websites I visit through apple aren't allowed through Safari. Does anyone have any input on this. I tried searching for older posts regarding this but wasn't able to find anything. If there is please just direct me. I've already downloaded the .pkg file and have the installer, just want to make sure beforehand. Again, thank you!!!
