Step 1: Connect SimpleMind for Mac to your Nextcloud server.

  • In the mind map explorer click the cloud setup tab and click “Connect”. If you don't see the mind map explorer, click "Mind Maps".
  • Enter the server, username and password and click connect.
  • This adds the Nextcloud tab in the Mind Map Explorer.
  • Click this Nextcloud tab to see the folders and files in Nextcloud.

Step 2: Copy existing local mind maps to Nextcloud.

Local mind maps are not synchronized with Nextcloud. If you want to store and sync an (existing) local mind map on Nextcloud, you need to copy the local mind maps to the Nextcloud tab. This is a one-time copy.
  • To copy, select the mind maps - right click – “Copy to Cloud” – “Copy to Nextcloud”.
  • You can now delete the copied local mind maps, they are now mere copies.

Step 3: Work directly in the Nextcloud tab.

You can now create new mind maps that are synced directly with Nextcloud. All your changes are synced at regular intervals and at shutdown. To manually force synchronization, use the manual_sync_with_cloud“Synchronize with Nextcloud” command.


  • Open mind maps from within SimpleMind only. Opening a mind map from outside SimpleMind, for example via Finder, will import the mind map as a new local mind map.
  • Real time collaboration is not (yet) possible. Only one person a time should edit a mind map. If two persons edit the mind map at the same time a conflict copy will be created to prevent any losses.
