1/ Set up and use Universal Clipboard — The new Universal Clipboard feature in macOS Sierra and iOS 10 allows you to copy content, including text, images, photos and video from one Apple device and paste it in another. For example, you can browse a recipe on your Mac and paste the ingredients right to the grocery list on your iPhone. In theory, all you have to do is make sure all your Mac and iOS devices are on the same Wi-Fi network and that Bluetooth is enabled on your iPhone and/or iPad. Copy on one, choose Paste on the other … but if you can’t make this work (and there can be a lag between the cCopy then the ability to Paste), try signing out of iCloud on all of your devices, and then signing back in.
2/ Use Markup in macOS Sierra Photos — If you’re editing your images within Photos, you can apply filters, remove red-eye, crop things and so on. But macOS Sierra added Markup to Photos, which lets you add text boxes, shapes or drawings to your images.
Select the picture you’d like to annotate, then click the edit button in the toolbar (it looks like a set of sliders). In edit mode, you’ll see a list of tools along the side. Click on Extensions and the Markup option appears. Click this and you can add circles or stars around people, insert text boxes and more.
3/ Reopen recently used tabs in Safari — Launch Safari for Mac and in the Mac’s menu bar for Safari, and the obvious way is to click History. From the list of options with the History menu item, slide down to select Recently Closed. Hovering over this menu item produces a new contextual menu that shows all recently-closed Safari tabs. Select the item that you wish to reopen and click on it. You probably – hopefully! – knew that, but there’s a faster way to do it:
4/ Reopen recently used tabs in Safari (2) —To the right hand side of any open tab in Safari there is a Plus(+) icon. Clicking this opens a new Safari tab window. However, if you right-click (or hold down the Control key on your keyboard and normal-click) on the Plus(+) icon, a new menu appears that shows all recently-closed tabs. Select one to launch it.
5/ Turn Flash off for sites except for some — Flash sucks – it’s a resource hog, can allow malware in and it’s generally unpopular for good reason. So let’s take control of it. First, open any sites where you know you still need to use Flash (which allows those little web animations to play.) There are alternatives to Flash, and many sites including YouTube, have switched to the much better, higher resolution and faster HTML5. But if you’re stuck with needing some sites that still use Flash, read on.
On your Mac, open Preferences>Security>Plug-in Settings… and choose Adobe Flash Player. Set ‘When visiting other websites’ to Off to cause all other servers to send you HTML 5 instead (this is faster, more secure) content when available. But you can choose from among your open sites to give them permission to use the Flash plug-in and Safari will remember your choice for your next visit.
