First Launch (Important!)
Since Markview is not notarized (to keep it free and open source), macOS will show a security warning. This is normal and safe to bypass:
Method 1: Right-click method
- Go to Applications folder
- Right-click (or Control-click) on Markview
- Select "Open" from the menu
- Click "Open" in the dialog that appears
- This only needs to be done once
Method 2: System Settings method
- Try to open Markview normally
- When blocked, go to System Settings → Privacy & Security
- Find the message about Markview being blocked
- Click "Open Anyway"
- Enter your password if prompted
"Markview is damaged and can't be opened" This is the most common issue with unsigned apps. Fix it by:
- Open Terminal
- Run this command:
xattr -cr /Applications/Markview.app
- Try opening Markview again
This removes the quarantine flag that macOS adds to downloaded apps.
"The application is from an unidentified developer" This is expected. Use the right-click → Open method described above.
App doesn't open on M1/M2/M3 Macs
Make sure you downloaded the arm64 version, not the intel version.
- Right-click any
.mdfile in Finder - Select "Get Info"
- In "Open with:", select Markview
- Click "Change All..."
- Confirm the change
Now all .md files will open in Markview by default!
After installing Markview:
- Open Markview
- Press
⌘,to open Settings - Find "Command Line Interface" section
- Click "Install CLI"
- Enter your password when Terminal prompts
- Close and reopen Terminal
Now you can use:
mrkdwn README.md
mrkdwn /path/to/folder/- Quit Markview
- Drag Markview from Applications to Trash
- To remove CLI: Open Terminal and run:
sudo rm -f /usr/local/bin/mrkdwn
- To remove settings:
rm -rf ~/Library/Application\ Support/Markview
