So the other day I got myself a new MacBook Pro. I chose not to use Migration Assistant this time around, so I could install everything from scratch and avoid the build-up of cruft from previous upgrades getting onto my new notebook.
One job was installing GSAK. The Wine install went like a dream and I was able to import the database from the old installation easily using the Restore command.
GSAK gave me a prompt that a new version was available as an update so I thought “what the heck?” and clicked the update link. I was expecting it to freeze as I was running in Wine, not a native MS Windows platform but to my surprise it simply ran the installer and, lo! I had upgraded to 8.7. Happy with that.
