Whether you're updating to the latest version of watchOS (check out our watchOS 7 review for more on the new features) or considering a beta install, it's always good to have troubleshooting steps on hand just in case things get out of hand. While everything should — and usually does — go smoothly, once in a while, these simply don't update or install the way you'd expect. Sometimes it's a connection issue. Sometimes it's a verification error. Sometimes it won't reboot. And other times it just... does nothing.
If you can't install watchOS 7, here are a few things you can try.
Are you on the latest version of iOS?
You'll need to update to Apple's latest version of iOS before a watchOS update will show up in the Watch app, which, yes, means taking the plunge on both devices (the same goes for beta software). If you can't install watchOS 7, this is the first place you should check
Does your Apple Watch support watchOS 7?
watchOS 7 is only supported on Apple Watch Series 3 and above. If you have an original Apple Watch (Series 0), Apple Watch Series 1, or Apple Watch Series 2, you can't update to watchOS 7.
If you don't know which Apple Watch series you have, we can help with that.
Are you on an iOS beta seed?
We've heard a few reports in the past from people on iOS beta seeds who can't get watchOS updates to appear. There are a few causes for this: Your Apple Watch might not be enrolled in the watchOS public beta or watchOS developer beta program, even though your iPhone is. There may be an issue with installing the public seed over the beta.
If all else fails and you can't install watchOS 7 while your iPhone is registered as a beta device, it's best to bring your iPhone back to production software (and save yourself the trouble of a glitchy release).
Check your connection
It's also worth checking to make sure you're on Wi-Fi and your Apple Watch is recognizing your iPhone.
Note: Apple Watch does not support 5GHz Wi-Fi. You may need to switch your Wi-Fi settings over to a 2.4GHz network if you notice issues with installing software.
- Open the Settings app on your iPhone.
- Tap Wi-Fi. (Also double-check Bluetooth is on while you're at it.)
- Swipe up to bring up Control Center on your Apple Watch. If your iPhone is connected, you'll see a green Connected banner at the top of the screen.
Force Quit and restart
Still not working? Try force quitting the Watch app on your iPhone and restarting your Apple Watch.
- Open the Watch app on your iPhone.
- Double press the Home button to bring up the multitasking interface on iPhone devices with a Home button or swipe up from the bottom of the Home screen on iPhone devices with Face ID.
- Swipe up on the Watch app to close it.
- Swipe up on the Watch app card to force quit it.
- Press and hold the Side Button on your Apple Watch.
- Slide to Power Off.
Erase and repair
If neither of the above two steps worked, it's time to bring out the big gun: unpairing and re-pairing your Apple Watch.
Note: Unpairing your Apple Watch will automatically back up most of your information, but you may lose access to certain aspects, like your Apple Pay cards. You'll also have the Watch removed from Find My iPhone, and Activation Lock will be disconnected.

Apparently there’s a common problem with some generations of the watch where you get a system complaint about available space (you need 3.2gb). Here’s the answer: In the watch app on your iPhone, find Photos, and Music. Notice that they’re set to sync some resources with the watch. Turn these off, and reboot the watch. Another hint is to turn off Bluetooth, and force the update to happen on wifi to speed things up.
