Hi @Vikki Gibbs , 90% of our firm uses Macs and we haven't seen any issues. With that said, we have shared proofs via WF with clients (not yet...). With that said, someone can correct me if I'm wrong, it shouldn't matter what operating system you're on since WF is web-based (unless you're on the desktop version -- we aren't). What kind of issues are people having? I'd look more closely at the browser that people are viewing on. Just a thought! Brandon Hamm Bravo Group
