I’ve downloaded the new version, Rapidweaver8.1 and dragged it to the Application folder, but I get an update error when I try to check for updates that says I’m running it from a read-only volume like a disk image or optical drive. I’ve deleted it from my mac, reloaded it, moved it back to the application folder, and rebooted, but still get this error message.
Sorry, I recall the issue, but I can’t remember how I solved it. Probably by reinstalling the update a couple of times and crossing my fingers. No longer an issue for me.
