I’m running Classic 9.2.1 on a M1 Macbook. Is it safe to upgrade my OS to Sequoia, or do I have to upgrade RW?

Hi @ajenks,

RapidWeaver Classic (any version) should run fine on any Apple Silicon Mac with macOS Sequoia. Naturally it’d be a good idea to do a Time Machine backup before upgrading in case you need to do any kind of disaster recovery.

Let us know how you get on.
