 There's a new operating system for the Mac. It's called El Capitan. It's coming in the fall, but you can look at a beta of it this July, but we have the developer preview right now. Let's take a look. There's two things to know about El Capitan. The first is that it's faster. Apple has added metal to it, which means that graphics render faster, and in general it says that apps launch faster. So if we launch the Photos app here, you can see it's spun up and launched pretty quickly. In terms of experience, there's a few different areas you need to look at. The first is window management. So I'm going to open up Mission Control here, and you can see that it has a little bit of a lighter theme. I can take a window, I can drag it up to this area, add it to a new space. That's basically the way it worked before. But what you can do now is you can hold your finger down on the green spotlight button, and you see there's two different sides to the screen here. I can drop it in, and that's dropped it into a split screen view, and then I can choose the other app that I want to see in split screen, like Notes. Now I have two apps open in full screen mode, but in split screen. You can change the dividers between these things, and you can go back to your main window, and you can take another thing, you can put it into full screen mode, I can go back to the desktop, and so on. I can take this thing, and I can drag it into this Photos and Calendar, and now I've got another split screen view here. So it's pretty convenient if you use full screen apps, it works really well. Spotlight search has also gotten better in Al Capitan. If you start it, you can do a search for things like the weather in Toronto, and it'll give you the information for that thing. You can also search for stocks, all sorts of structured data. You can even search for cat videos if you want to. The other thing that Spotlight can do is you can use natural language. So for example, I could search for emails from Neeli, and it will show those emails. You can use all sorts of natural language. I could search for PDFs from June, and there's a PDF that I had open in last June about a terrible Android tablet. The neat thing about Spotlight is it doesn't just work inside Spotlight. You can use those same kind of natural language searches in Notes or Mail or a whole lot of other Apple apps. That's really kind of it for the big system level stuff in Al Capitan. There's a new system font, there's new support for other languages, but the really big changes come inside Apple's own apps. My favorite changes are in Safari. You can see here I've got a bunch of tabs open, and they're little. That's because they're pin tabs. They finally added this. It's something that Chrome has done for a really long time. You can see here I've got a bunch of tabs open, so I don't have to reload the page like I do with the bookmark. They're just sitting there loaded and ready to go, which is pretty great. The other thing that they've added in Safari, which is cool, is if you have something making noise like this Jimmy Fallon video, you can just click in the address bar to mute it. If you hold your finger down on that button, it also shows you all the tabs that have sound going, so you don't have to deal with being embarrassed in the office anymore. Speaking of things that Apple is finally doing, they're finally adding transit directions to maps. You can add a transit layer to your map screen. You can see here I can see all these subway lines. I can even zoom way in and look at an actual map of the underground station of a particular subway, which is pretty cool. You can click on a thing, and you can see what the delays are, at least in New York. It's not available in a lot of cities to start, but they'll be adding more as they go. It is everywhere in China, which is interesting. Mail has also seen a big improvement. Apple says that it can sync messages faster. They've also added some new full-screen modes. If I go into full-screen and I start a new compose message, I can start a bunch of them, and you can see that they are separated out into tabs. If I minimize it, it sits down here at the bottom of the full-screen, so I don't lose it. The other thing they've done in Mail is they're trying to add some structured data. I've got this email here that says, do you want to meet for lunch at 1 PM? Apple has added a little thing to let me automatically add it to my calendar. That works for basically calendar entries and contacts, but it's not as full-featured as what Google does with Gmail with flight tracking information and package tracking and all the rest. If there's one app that sums up what makes El Capitan cool, it's the Notes app. Apple's added a ton of new features and functionality. There's really boring stuff like ICANN, bold text, but you can also do other neat stuff. You can add checklists for shopping, milk, eggs, butter, and the dairy section. But on top of that, you can drag images into it. There's an image. You can even drag URLs into it. If I drag a URL in here, you'll see that it's created a neat little preview card that tells you what is inside that link. You can also share map locations to Notes. If I want to save this thing in this subway station into my Notes app, it pops up a little thing and now I've got that reminder in my Notes. There it is. The reason that Notes sums up how I feel about El Capitan is if you live in Apple's ecosystem, if you use its Notes app, if you use its Maps app, it's great because everything talks to each other and works together really well. Then Spotlight is able to search all of it with really natural language, so it's cool. If you don't live in those worlds, you don't quite get all of those features. Your email lives over in Gmail and your Notes live on Evernote and whatever else. That's a fine way to live, but it's not necessarily the way Apple wants you to live. What Apple wants you to do is use all of its stuff together and if you buy in, it feels really compelling.
