I’ve been asked to take over a website built in Rapidweaver. I’m glad to buy the software, but I’m running Yosemite and don’t want to upgrade to El Capitan yet because of some other compatibility issues. Is is possible to purchase a version of Rapidweaver that is compatible with Yosemite? Also, since I don’t know what version of RW was used to build this site, is there any risk that I wouldn’t be able to edit the site using an over version of RW?
Any advice, suggestions appreciated.
