macOS High Sierra (10.13) is the main OS on my Mac and it boots without issue. However, the recovery partition is corrupted and I cannot boot to it without seeing an error. How do I reinstall the recovery partition without having to disrupt my working main OS?
The machine I'm using was upgraded from Mavericks.
Meta Note: While there are similar questions for previous MacOS versions, I think unique issues relating to the new APFS in High Sierra justify a new question.
