I have a 2015 MacBook Pro running Sierra. I'm hoping to upgrade to High Sierra or Mojave and still have my CS6 and Quark2016 software work WITHOUT needing to reinstall the software. Will upgrading to High Sierra break all my software? (I purchased my Mac used, and it came with the software, so I don't have any of the registration info. I am a freelancer and don't always do enough business to warrant the expense of the Adobe subscription.) Any advice would be appreciated. Thank you!
