I have a Macbook pro early 2015 and am currently running MacOS High Sierra Version 10.13.6. For the last couple months I get a message every time I open Google saying I need to update my OS in order for google to continue working properly. I believe I can upgrade to Catalina or Monterey. I really only want to upgrade to be in compliance with Google. Everything is running smoothly now, and I'm concerned if I update my OS, I will get an error message from Apple saying my Macbook Pro is not compatible. I have a small 120 gig hard drive with 25 gigs free and I have only 8 RAM. My past experience with Apple has been they keep telling you to upgrade until the only solution is to buy a new Mac! Any advice greatly appreciated,
Oski
