With the photos app in the new Mac 0S Sierra, you can mark up your photos with shapes, text and drawings without leaving the app.
Open up Photos and click on the Edit button, which is the three lines at the top right next to Detail, then choose Extensions and choose Markup. You can draw lines; change colors; add circles, squares and text; and use a magnifier. You can revert back to the original by clicking on Undo. This feature is nice when you want to take a photo and add some text telling someone where it took place, drawing arrows to locations, spots and to people.
You can export a photo on the iPhone to your iCloud drive, and it will show up on your Mac's iCloud drive. On the iPhone, select a photo you want to send to the Mac. On the bottom left, click on the box with an arrow pointing up. On the very bottom, menu scroll to the left and choose ADD TO ICLOUD DRIVE. You can choose a certain folder if you have one created, and it will now appear on your Mac's iCloud drive.
So, what is an iCloud Drive? First, everyone should have an iCloud account, which is actually an e-mail account. When you sign in to www.Icloud.com, your photos, calendar, notes and e-mail are all there. It's like a backup of your hard drive but safer storage. PCs use a program called Carbonite. The nice thing about iCloud Drive is that it syncs with all your other Apple devices. So if you store a photo on your Mac, it's now on your iPhone, and now you can add documents to your iCloud drive. Open up System Preferences and click on iCloud, iCloud Drive, Options and check "Desktop & Documents Folders." iCloud Drive places an icon of both Mac and iPhone. Remember, if you have a lot of pictures on your iPhone, you might have to buy more gigabyte space.
In Windows, you can split the screen in half with two programs running. Well, on the Mac desktop you can do the same. Open up two programs like Mail and Photos and click and hold on the green button on the top left.
Google just launched Google Trips, the ultimate travel app.
A really cool app for you camera people is PABLO, which can do long exposures (like watching a city freeway scene with trailing red lights) on your iPhone camera.

On the iPhone, you can double-click at the end of a sentence and it places a period. Now you can do the same on the Mac. Go into System Preferences, Keyboard and check the box "add period with double-space."
You can move the top right bar icons on the Mac - like date, time, spyglass and Wi-Fi - around by dragging them to either side.
Using 3D touch on the iPhone, you can press hard on the camera icon; a menu pops up allowing you to quickly create a "selfie," record, take a photo or film in slow motion. If you press hard on a photo and swipe up, you get a menu where you can quickly copy, share or remove.
On the Mac in the new Sierra, you can now rearrange the files in Finder so that folders are listed on the top and files below. Go to Finder, Preferences, Advanced and click on "keep folders on top."
When sending an Emoji using the iPhone's text message app, if you first click on an Emoji, it appears really big, but if you start out typing in text then click on an Emoji, it is small.
A neat feature for a quick response to a message you just got is to press hard on that message; a small menu appears above allowing you to send out a thumps up, ha ha or heart.
