Activate FM Loupe
FM Loupe needs an active key on each Mac that uses it. One key covers two Macs. Activating takes a minute and needs the internet once.
Enter your key
- Install FM Loupe with the installer from the beta page. You can paste your key into the installer and skip the next steps: FM Loupe turns it on the first time FileMaker Pro opens.
- Open FileMaker Pro and choose FM Loupe › Enter Licence Key…
- Paste your key, tick the box to agree to the terms, and press Activate.
The same window is in FileMaker Pro › Settings › Plug-ins › FM Loupe › Configure…, under Licence…. It's there even when the FM Loupe menu is turned off.
Don't have a key? Get one on the beta page. Lost it? Sign in to your account to see it again.
Two Macs per key
Your key works on two Macs at a time. If you activate it on a third Mac, FM Loupe lists the two it's on and offers Free it, use here next to each, so you can move the key without leaving FileMaker. You can also see and remove your Macs on your account page.
To give a Mac's place back before you sell it or stop using it, open the licence window on that Mac and press Remove this Mac.
A Mac that only runs agents
A Mac that drives FileMaker only from Claude Code or Codex, or a build Mac without FileMaker Pro open, needs the key too and counts as one of the two. In Terminal:
fmloupe licence activate YOUR-KEY --agree-terms
fmloupe licence status shows what's saved on the Mac, and fmloupe licence remove frees its place. If both places are taken, the command lists the two Macs; run it again with --replace and the id of the one to free.
When FM Loupe stops
Without an active key, FM Loupe stops and says why: the window, the menu and every agent request show the reason and how to fix it. Nothing in your FileMaker files changes.
- Offline. FM Loupe keeps working for up to seven days without the internet, then asks to check in once.
- Key ended or turned off. Your key has an end date. Write to joe@datacraftdev.com to extend it.
- New Mac or a restored backup. The key belongs to the Mac it was activated on. Enter it again on the new Mac, and free the old one if it's still listed.
Press Check now in the licence window after you change anything on your account, so FM Loupe picks it up straight away.
