Since I started using mac in 2014, I’ve had issues with spell check in keynote. I think I just don’t understand how it work. It just seems so bad that this must be the issue. I click “next” or “change” to replace a word during a spell check and it gets “stuck.” It’s not frozen, because the app isn’t frozen, just the spell check window won’t move forward and has to be closed. I then click the next slide and start again. Any tips on using spell check in keynote? I don’t rely on it, but it’s a nice last check in power point.
