Tether - The wireless leash to your Mac.

By Fi a Fo Ltd

Open iTunes to buy and download apps.


With Tether, your Mac automatically locks when you're not there and springs back to life when you return. It's that simple!

*NEW* Add-ons

Add-ons are collections of extra features and functionalities which can be purchased in-app on iOS. Two add-ons are currently available:

Trigger Apple Menu actions on your Mac from your iPhone. Remotely lock and unlock your Mac, set it to sleep, restart, shut down or even log out.

Control the playback and volume of media playing on your Mac. Mute sound, play videos, skip tracks, pause movies… all the media controls of your Mac, triggered remotely from your iPhone.

Secure your Privacy
Whether it is when we’re taking a call, walking to the kitchen to make a cuppa or stepping out for lunch, one of the things we tend to remember to take with us is our iPhone. So we designed Tether for iOS and Mac to take advantage of our unique ‘iPhone separation anxiety’ behaviour by automatically locking your computer whenever you step away to ensure your digital files and private data are kept safe from prying eyes.

Improve your Workflow

As soon as you return, Tether will automatically enter your password and unlock your Mac allowing you to continue from where you left off. No password entry, just rock on up and you're in!

No Battery Drain

Tether communicates seamlessly between iPhone and Mac using Bluetooth Low Energy (BLE) and draws very little power. Which means you don’t have to worry about Tether draining your iPhone’s battery.

Doesn’t work well

Concept is great and apparently the old version of the app worked great, but my first experience has been with this newest version. In short, it doesn’t work well at all. Frequently, I have to force close and reopen the iOS app to get it to connect to the computer, or I have to delete all linked devices and re-link them all again. However, again this only works for a short time (like hours) before again losing the connection. At other times, my screensaver will start and computer lock while my phone is just sitting on my desk 2 feet from the computer. I am using the newest version of Yosemite on a 2014 iMac and an iPhone 6 Plus, so this really should work.

Started off good...

This app started off really well. But each release seemed to make the app not work a little bit more and progressively got worse. I remember when I first installed it I walked away. Upon returning, it unlocked. Wow! After time it seemed that the iPhone and MacBook lost its connection and I needed to constantly restart the app on each device and re-pair. When the sensitivity slider was introduced, sensitivity just got wonky, even with the phone an inch away. It would get in some weird lock/unlock cycle over and over. Really wish the devs would just say we're working it or tell us they are abandoning ship.


Can't have it hook up by a cord, if you don't have a certain computer with very specific specs it won't work. It has to have Bluetooth, but won't do traditional tethering by the USB cord. So disappointing, made a small market that from the looks of it isn't that good....

Tried with an updated system, the phone kept turning the computer to sleep mode even though it was sitting right next to the computer and I had the settings set to very far away.

The tech world sees "tethering" as something different, and this app definitely doesn't meet that expectation.
