Apple occasionally releases updates for iOS, watchOS, tvOS, and macOS in the form of developer previews or Public Betas for iPhone, iPad, Apple TV, and Mac (no Public Beta for Apple Watch).
While macOS High Sierra introduces several new features, beta versions of any operating system aren't the final release, so encountering numerous bugs with betas is to be expected. Typically, it's advisable not to use beta versions on your primary iPhone, iPad, Apple Watch, Apple TV, or Mac.
That's why users are advised to 'stay away' from developer previews unless you need them for software development and use Public Betas cautiously. If you depend on your device, wait until the final release.
Before troubleshooting
Identify where the issue lies. If the process of downloading or installing macOS High Sierra beta fails, you can apply the following troubleshooting steps. However, if you encounter issues with a specific application, it's best to isolate and troubleshoot the app issue, try uninstalling and reinstalling the app, or check for updates.
What to do if you can't download and install macOS High Sierra?
If you've followed the steps for downloading and installing macOS 10.13 High Sierra correctly but the version still isn't functioning, in this case, try force-quitting the Mac App Store or the macOS installer and start the installation again.
Step 1: Click on the Apple menu button at the top left corner of the screen.
Step 2: Select Force Quit.
Step 3: Select App Store or installer (whichever isn't working).
Step 4: Select Force Quit.
Step 5: Select Force Quit once again to confirm.
What to do if macOS High Sierra freezes or becomes unresponsive?
In this case, patience is key. If possible, wait for a period of time for your Mac to function, usually after half an hour, your Mac may resume normal operation.
If you can't wait or if after waiting for a period of time your Mac still isn't working, you'll need to force a restart. First, try by pressing and holding the power button on your Mac until it shuts down completely, then turn it back on.
If your Mac doesn't respond to the power button, the last resort is to unplug the power cord to shut down your Mac.
What to do if macOS High Sierra won't restart?
Boot into Recovery Mode
If your Mac starts up and only loads a blue screen, in this case, try booting into Recovery Mode. Here's how to boot into Recovery Mode:
Step 1: Shut down your Mac.
Step 2: Power on your Mac again, press and hold the Command + R key combination until you hear the startup chime or see the Apple logo.
Step 3: Select Disk Utility from the macOS Utilities window.
Step 4: Choose the disk running High Sierra.
Step 5: Select Repair Disk.
Wait for the repair process to complete, and your Mac will restart normally.
Changing partitions
The smartest approach is to try partitioning your Mac's hard drive and booting your Mac from the Sierra partition to address any issues there.
If all else fails, simply erase the High Sierra partition and start reinstalling macOS High Sierra beta.
