Everytime I try installing an application from App Store, it states that I need. higher version which is 10.15. Further my system software is up to date which is not true, what can I do ? The latest update I am currently on is High Sierra version 10.13.6. how Can I Update to 10.15? knowing that it is not available on the App Store update section.
