One of the features that Apple introduced in iOS 6 and Mac OS X Mountain Lion is tab syncing in Safari between multiple devices. This means that at any point, you can see any of the tabs that you have open on all of your devices. For me, I have a Macbook, an iPhone 4S, and an iPad. At any point, I can access the tabs open on any of these devices. Here is how:
1. Make sure that all your devices are updated and that Safari on your Mac is running the most recent version.
2. Make sure that you are logged in to iCloud on all your devices with the same account and the “Safari” box is checked on your Mac and that the “Safari” toggle is switched to “On” for your iOS devices. You can access these settings in the “System Preferences” on your Mac and in the Settings app on your iOS device. Click or tap on iCloud.
3. Now, you will see a small iCloud icon next to the navigation buttons in Safari on your Mac. On your iOS device, you will see iCloud Tabs in the bookmarks list. Tapping on either of these will bring up a list of all your open tabs on all your devices.
