I think you might mean 15.7, which is the latest version of macOS 15, and yes that’s perfectly fine to update to. Just make sure that Scrivener is updated as well. Version 3.4 is the latest stable build, but if you use lists and styles, you really should update to the beta version, which although aimed primarily at macOS 26, contains a very important fix for lists that are next to styles. If you use those right next to each other, and are still on an older OS version and have yet to see how badly Apple broke their list engine, do not use 3.4 with 15.7.
