Office for Mac isn’t doing so hot on El Capitan, it seems. (I personally haven’t had many problems, but I personally don’t use Office that much, so your mileage may vary.) Luckily, Apple pushed out updates for all three of its iWork applications for the Mac on Thursday. What excellent timing!
Pages 5.6 supports El Capitan’s new Split View feature. It can open documents from both Pages ’08 and ’06 (which doesn’t seem like a feature to crow about, to be honest, but this was a big problem up until now).
