Has your Mac seen beta days? Here's how to troubleshoot some issues you might be having.
If you're on the macOS High Sierra beta, you may be experiencing some issues. And that's completely normal; it isn't fully formed software yet, hence the "beta" moniker. That being said, you don't have to live with bugs and annoyances until the full release comes out this fall.
Here are some things you can try to figure out what's wrong and perhaps alleviate some of your macOS woes.
Apple occasionally offers updates to iOS, watchOS, tvOS, and macOS as closed developer previews or public betas for iPhone, iPad, Apple TV and Mac (sadly, no public beta for the Apple Watch). While the betas contain new features, they also contain pre-release bugs that can prevent the normal use of your iPhone, iPad, Apple Watch, Apple TV, or Mac, and are not intended for everyday use on a primary device. That's why we strongly recommend staying away from developer previews unless you need them for software development, and using the public betas with caution. If you depend on your devices, wait for the final release.
Before troubleshooting
Figure out where the problem lies. If it's in downloading or installing the beta, then fair enough. If, however, you're only having trouble when using certain apps, then it's best to try and isolate the issue to just those apps. If it's a single app, try uninstalling and reinstalling or checking for updates.
What to do if High Sierra doesn't seem to be downloading or installing
If you're sure you've signed up and installed the beta certificate properly (you can double-check our guide for installing the developer beta), and it's still not working, try force-quitting the Mac App Store or macOS installer and starting over.
- Click the Apple menu button () in the top left corner of your screen.
- Click Force Quit.
- Click the App Store or installer (whichever's not working).
- Click Force Quit.
-
Click Force Quit again when asked if you're sure.
What if macOS High Sierra freezes or stops responding?
You can start by waiting. If you have time, leave your Mac for a while. It might work itself out after half an hour.
If you can't wait or waiting just doesn't work, you'll have to force a reboot. First, try by holding down the power button on your Mac and waiting until it shuts off and turns back on.
If your Mac won't even respond to the power button, then as a last resort, you can simply unplug it. Unplugging it should be the last thing you try, since you could end up bricking it altogether.
What to do if macOS High Sierra won't restart
Boot in Recovery Mode
If your Mac boots up and just sits in a gray screen or you just get spinning wheel of death from the start, try booting in Recovery Mode. Here's how:
- Turn off your Mac.
- Turn it on and hold Command-R until you hear the startup chime or see the Apple logo.
- Click Disk Utility when the macOS Utilities window shows up.
- Click the disk that's running High Sierra.
- Click Repair Disk.
Wait for the repair to run. Your Mac will likely restart when it's finished.
Change partitions
If you've done things the smart way and partitioned your Mac's hard drive, start up your Mac from the Sierra partition and troubleshoot from there.
If all else fails, just wipe the High Sierra partition and start all over again.
