Probably a bit of a stupid question, and I probably already know the answer so this is more of a confirmation for me.
With my Lazarus (2.0.12) install on High Sierra, what versions of macOS should I expect my compiled projects to run on?
I also cross compile to 32 bit. This an 'out of the box' install with just the 32 bit compiler option added on (following the FAQ on the Wiki, IIRC). X-Code is whatever version is the latest for High Sierra (to be honest, I hardly use X-Code, and when I ran it to find out a version number it wanted to install more stuff...so I quit it, for now).
Also, again I probably already know the answer to this (and may be answered by the previous question anyway), if I were to upgrade my machine to Mojave or Catalina, will my projects still run on High Sierra?
(on the plus side I do also happen to have a Mac here which won't go past High Sierra...but doesn't have Lazarus installed on it - yet).
