MacBook Pro (mid 2012)
I just got this computer and am wondering do I need to update from High Sierra to Mojave or Catalina. In your personal opinion which one and how do I do that. So far neither one shows anywhere in the App Store. I have read through and tried multiple links within the support community. The link pulls up a blank page and sits.
I will be using this computer to run a business and to attend college (again) completely online.
