Connecting MacBook Pro to iPhone is not something hard and people has been doing it for a long time. Now, there is a new way called Continuity that allows you to work with both as if they were just one. Bear in mind that Bluetooth has to be on for both devices and they also have to be signed into the same iCloud account.
On your MacBook Pro
Go to your “System Preferences” menu
Clicking on the “Apple” button on your extreme upper left part of the screen will drop-down a menu from which you have to choose “System Preferences”.
Go to your “General” menu Clicking on the “General” icon on your top left side of the menu, you will enter the “General” menu.
Check the box to allow handoff between iPhone and your Mac
Clicking on the box right next to “Allow Handoff between this Mac and your iCloud devices”, you will activate this feature on your Mac. If it was already on, leave it on.
On your iPhone
Go to your “Settings” menu
Touching the “Settings” icon on your iPhone will take you to the on the “Settings” menu on your iPhone.
Go to your “General” menu
Scroll down until you see the “General” icon and then tap on it to enter that menu.
Go to “Handoff” menu
Tap on the option that says “Handoff” and enter your iPhone´s handoff menu.
Turn “Handoff” on
If the slider is color green, it means that the handoff is on, otherwise, it will appear on red. If it is on, leave it like that and if it is off, turn it on.
Remember that for Mac Continuity to work properly, both devices should have the Bluetooth on and also be logged into the same iCloud account. Continuity will allow you to seamlessly work with both as if they were one.
There are other ways to partially connect your iPhone to your MAC but none is as complete as Continuity.
