How to open .ME files on Mac
To open .ME files on Mac, open the file in a plain-text editor (for example, TextEdit set to plain text) to view or edit the source.
Step-by-step instructions
- Open the file in a plain-text editor (for example, TextEdit set to plain text) to view or edit the source.
- For formatted viewing, install and use groff to process the file with the ME macro package and output a PDF/PostScript.
Common issues
The file opens as “garbled text” or looks like code
.ME files are source documents containing roff requests and ME macros; they are meant to be processed by troff/groff, not read like a finished document.
- Open the file in a plain-text editor and confirm it contains roff/ME markup.
- Render it with groff using the ME macro package to produce PDF/PostScript, then open the rendered output in a viewer.
Double-clicking does nothing or opens the wrong app
Your system may not have a file association for text/x-troff-me (or it may treat .me as a different text type).
- Use “Open with…” and choose a text editor to view/edit it.
- Optionally set your default app for *.me to a text editor or a roff-aware editor if you work with these files regularly.
Rendering fails due to missing macros or tools
Formatting requires a troff implementation (commonly groff) that includes the ME macro package.
- Install groff and ensure the ME macros are available (the groff documentation lists “me” as a supported macro package).
- Try rendering again after installation, or test on a Linux distribution where groff is commonly available.
Security note
.ME files are typically plain text, but roff/troff processors are complex parsers—avoid rendering untrusted .ME files with advanced macro features on sensitive systems.
