Is there a recent set of instructions on how to migrate to a new machine?
I’m not allowed to enable iCloud or Dropbox syncing in my environment. I actually asked this years ago ( Manually move Agenda data to a new computer ), but those instructions don’t seem to apply anymore, as I’m not seeing all the folders mentioned.
In Finder, choose Go > Go to Folder and paste the path. Right-click the folder, compress it, and copy the zip across to the new Mac. On the new machine install Agenda first quit it, then unzip and replace the same folder at the same path. Launch Agenda and your data should be there.
