I have a very simple export plugin. It used to work fine and I didn't touch it since (only updated the OS X and LR), but now it fails on OS X with LR 5.6. Specifically, this line
local success, pathOrMessage = rendition:waitForRender()
returns false in the success variable. But the exactly same plugin still works on Windows. What gives? How can I troubleshoot this issue?
Any advice? I find this issue very odd and have no idea how to fix it.
Looking at the error message in pathOrMessage could be a start.
