Upgrading MacOS From 10.9.5 To 10.13 - MacPorts Implications

[Michael Newman]

I have an old 2009 MacBook Air (2GB RAM) which is running MacOS 10.9.5 (Mavericks). I’m now getting warnings from Apple, Google (Remote Desktop) and DropBox (among others) that this version of the OS will no longer be supported "real soon now".

I have an installer for High Sierra (10.13) which Apple downloaded to my machine and attempted but failed to install. (All this was done without my permission.)

This machine doesn’t do too much except run a bunch of shell scripts that power a webcam and some other shell scripts that keep me connected to a captive portal Internet connection. These shell scripts depend on many MacPorts installations.

I have a couple of questions:

Will this old machine actually run 10.13 without blowing up?
If I install 10.13 over 10.9, will I have to uninstall and reinstall MacPorts?

I have been diligent about keeping MacPorts updated. I visit the location where this machine is located only a few days per month, but always do an upgrade soon after arriving.

TIA
