Unable to use older versions softwares on my MacBook with macOS High Sierra.
I use a MacBook Pro (15-inch, Late 2011) and had to reset the laptop. I cannot load old versions of my Microsoft Office software or even Apple's own Pages, Numbers and the rest.
How do I fix this problem? I cannot afford a new laptop but always believed in Apple. Is there a way for me to continue using my loved, and in mint condition MacBook Pro?
Please help me finding a way to install Microsoft (I am a legal user and paid for many years but the older Office is not available) and Apple older programs, Including the awesome Airmail I got to love.
