The Apple Worldwide Developers Conference is traditionally when the company unveils new versions of it's operating systems for Macs, iPhones, and the Apple Watch. This year, however, the most interesting changes are likely coming to the iPad with the release of iOS 13.

We all know Apple is one of the most tight-lipped companies in terms of leaking what's coming, but that doesn't mean it isn't our favorite guessing game. Besides, it's a developers conference, which means we already know that most of the updates will be around the software that runs the devices we love.

Here are a few things to watch for during the keynote event on June 3rd:

iOS 13 updates.

Probably the most anticipated announcements are those that relate to the operating system we carry in our pockets every day. iOS, which powers iPhones and iPads, is painfully overdue for some major retooling. It looks like you can expect to see a new home screen, dark mode, and better multi-tasking on your iPad. 

Also likely are a redesigned Reminders app (which is the best iPhone app by the way), and new features in Messages that include profile photos and better privacy control. There's also a good chance we'll see a new Mail app, which is long overdue. If all they do is add a share sheet, and snooze features, it'll be dramatically better than what exists today. 

MacOS 10.15

The biggest change expected to come to the desktop operating system is Marzipan, which is a framework for developers to bring iOS apps to the desktop. As an example, Apple previously released its News app on the Mac, which was previously only available on the iPhone and iPad. This would also enable Siri Shortcuts on the Mac, which could have a dramatic impact on routine workflows that you do every day.

The other big change is the long-needed breakup of iTunes into separate apps. MacOS is likely to get Apple Music, Movies, and a Podcasts app, similar to what we currently have on iOS. In fact, because of Marzipan, these won't just be similar to what we have, they will be iOS versions brought to the desktop.

WatchOS 6

Mostly, the big change on the Apple Watch is the ability to download apps directly to your wrist via its own App Store. Previously apps had to be downloaded on your iPhone and then sync'd with your watch. A few other improvements include a Books app for listening to audiobooks and a calculator app for, you know, adding up the tip in a restaurant when you forgot your phone. Or forgot how to do basic math. (I know, math is hard).

New Macs

Apple has been known to introduce new Macs at this event, and there's a good chance we'll see either the long-awaited Mac Pro, or MacBook Pros. Both are ready to be refreshed, and Apple has been promising a new Mac Pro for years, even telling us to expect them in 2019. With last year's introduction of the iMac Pro, and the recent upgrade to the Mac Mini, the Mac Pro is the only Mac that hasn't been updated since 2013. 

How to watch.

Apple always livestreams the keynote on their special events page, as well as from the events app on your AppleTV. You'll also find it live-blogged at a variety of places across the internet. It's not hard to find if you know how to use Google. 

What we won't see.

If you're waiting for the next iPhone, sorry, this isn't your event. Apple usually holds a separate event in the fall to introduce its newest smartphone. And if you happen to be waiting for Apple to jump on the foldable phone bandwagon, I hate to be the bearer of bad news. It's not going to happen.

I also don't think we'll see a new iPad Pro at this event. It's probably coming soon, but I don't think we'll see it before the fall. There's a chance I could be wrong, especially with the updated iOS13, but I think it's more likely it'll be introduced at a special event later this year. 

Finally, I don't think this will be the event we see a new Apple 6K Display. As much as I would like to see one, I'll probably have to keep using my original 16-year-old 20" Apple Cinema Display -- which works flawlessly by the way. Sure all the ports are out of date (looking at you FireWire), but it's still the best monitor I've owned for everyday use. I definitely hope that Apple gets back in this game, but I don't think this is when we'll see it.
