mdPV Support

Something not working, or an idea for the next version? Email info@nikielhard.se and include your macOS version and, if you can, the Markdown file that caused the problem.

Quick Look is not showing a preview

macOS caches Quick Look extensions, so a newly installed copy of mdPV is sometimes ignored until the cache is reset.

Make sure mdPV.app is in your /Applications folder.
Open Terminal and run qlmanage -r, then qlmanage -m.
Log out and back in.
Press Space on a .md file in Finder again.

Images in my document do not appear

Images embedded in the document render inline. Images referenced by a relative path do not, because the App Sandbox only grants access to the files you explicitly open. This is a macOS security boundary, not a bug in mdPV.

A Mermaid diagram shows its source instead of a diagram

mdPV renders flowchart, sequence, state, class, entity-relationship and XY charts. Pie and Gantt diagrams are not supported yet and fall back to showing the diagram source so nothing is lost.

I purchased editing but the editor is locked

Choose mdPV ▸ Settings and click Restore Purchases. The unlock is a non-consumable tied to your Apple Account, so it restores on every Mac you sign in to with that account. If it still does not unlock, email the address above with your purchase receipt.

Requirements

macOS 15.6 or later, on Apple silicon or Intel.
