How to Use Instant Wi-Fi Hotspot in OS X Yosemite with an iPhone

The iPhone has long had the excellent Personal Wi-Fi Hotspot feature, which effectively turns an iPhone or cellular iPad into a wireless router that Macs and other devices can connect to. That iPhone Hotspot feature gets even better for Mac users running OS X Yosemite, because you can now enable the iPhones personal Hotspot feature remotely just by connecting to it – the rest is automated. This is called Instant Hotspot, and it’s an excellent trick to use to speed up a personal hotspot connection, when you’re traveling or telecommuting, or just when you need an alternative internet connection for your Mac.

Instant Hotspot requires OS X 10.10 or newer, iOS 8.1 or newer on an iPhone or cellular iPad, the devices must be using the same iCloud ID, and finally, you’ll obviously need a cellular plan that includes the personal hotspot wi-fi feature. Many cellular providers offer this as part of their standard package, while others make users pay extra for the service. Assuming you have all of those requirements met, the rest is remarkably simple and you don’t even need to fiddle with the iPhone to toggle on Personal Hotspot like you normally would.

Enabling iPhone Wi-Fi Hotspot from a Mac with Instant Hotspot

1. With the iPhone nearby, pull down the Wi-Fi menu on the Mac
2. Look under the light grey text section titled “Personal Hotspot” for the name of the iPhone with the Wi-Fi Hotspot feature and select it as you would any other network
3. Wait a moment or two for the connection to establish between the Mac and iPhone, you’ll see the cellular reception, data speed (LTE, 3G, 4G), and battery life of the iPhone in the menu bar

That’s it. On the iPhone, the menubar will turn blue as it typically does when the wi-fi hotspot feature is in use and a user is connected to the iPhone or cellular iPad. Apple demonstrates both sides of this well on the OS X feature page, shown here:

Personal Hotspot and Continuity tends to work best at close range, so aim to have the iPhone somewhat remotely close to the Mac, within 15 feet or less is probably ideal but that’s just an estimate based on experiences. Using wi-fi hotspot can end up consuming a ton of bandwidth, so consider following some of these tips to reduce the amount of data you use when connected to an iPhone Hotspot.

Disabling iPhone Personal Hotspot from the Mac and OS X Instant Hotspot

To remotely turn off the Personal Hotspot without fiddling with the phone, simply pull down the Wi-Fi menu again and either select “Turn Wi-Fi Off” or choose to connect to a different wireless router connection. Simple, and just like connecting to the iPhone with Instant Hotspot, you don’t need to use the actual phone and mess with settings to get things working.

The Hotspot will also automatically turn itself off after a period of inactivity, this is a feature aimed at preserving the battery life of the iPhone.

Troubleshooting Instant Hotspot

If you’re having any issues with this be sure that the iPhone is running iOS 8.1 or newer. You may want to double-check that Personal Hotspot is usable on the iPhone and even toggle it into the ON position directly and connect, some users have reported that the Instant Hotspot feature works better after the Mac and manually connected to the Personal Hotspot from the iPhone at least once. As already mentioned, if you don’t have the wi-fi hotspot feature on your iPhone, you’ll likely need to contact your cellular carrier to enable the service.

Instant Hotspot is part of the Continuity feature set, which is included with the latest versions of OS X and iOS and allow for more seamless use between Macs and iPhones and iPads. Continuity also includes the ability to make and receive phone calls on the Mac, the excellent Handoff feature which allows you to pass active app sessions between iOS and OS X hardware, enhanced messaging features, and AirDrop.
