came across this problem after installed scrivener on a new MacbookPro M3. If I try to compile a document with MultiMarkdown to latex, scrivener crashed. The same process on a Mac mini M2pro works without a problem.
After digging deeper what could the problem, I came across, on the Mac mini is Rosetta installed, on the new MacBook not.
After installing MultiMarkdown from Homebrew, as I don’t want install Rosetta if possible, it looks like it works now.
