I am running the latest beta (Version 3.0.1 (1119)) and it opens documents happily from the File/Open menu. Trying to open the same document from Finder triggers the warning "Apple could not verify “hogarth-curves.md” is free of malware that may harm your Mac or compromise your privacy." and gives me the option to "Done" (which does nothing of course, or "Move to Bin".
Is there some setting I have missed?
Actually this may not just be related to Marked after all.

I’m seeing this on macOS 26.4.1 with Marked 2 (App Store). I can’t reliably double-click .md files to open them—setting “Always open with” shows the malware warning and doesn’t persist globally (only applies to one file). Even after approving via right-click → Open, it doesn’t stick. Apps like MarkChart work fine (default app sticks, no repeated prompts), so this seems specific to Marked. It may not be fully registering as a handler/editor for .md, which could explain why Finder won’t persist the association.
