macOS High Sierra beta problems are frustrating MacBook, MacBook Air, MacBook Pro and iMac users as they test out the latest software. If you run into issues, you can try the fixes listed below before downgrading to macOS Sierra.

The developer beta and public macOS High Sierra beta let users try out fun new macOS High Sierra features, but it comes with bugs and problems that are common in pre-release software.

Users testing the macOS High Sierra beta are complaining about battery life, performance problems, WiFi issues, installation problems and much more.

At this stage in the macOS High Sierra beta, you may need to downgrade to fix some problems, but before you do that, check out these fixes for common beta problems. The problems are one reason not to install the macOS High Sierra beta.

Here are the most common macOS High Sierra beta problems and how to fix them when they ruin your day.

How to Fix macOS High Sierra Beta Installation Problems

There are not a lot of macOS High Sierra beta installation problems, but there are two that you need to know about.

The first one is when the macOS High Sierras beta profile installer fails to complete. Our first several attempts ended early when the installer hung up on the last part. We had to force close the installer and then restart the MacBook before it completed. If this happens to you, restart your MacBook and try again, if it keeps happening, download the installer again.

Another issue we’ve seen is that the macOS High Sierra beta will not install on a Mac that has Server software on the primary disk. To fix this, remove the Server.app from the Applications folder, reboot and then install the beta.

Make sure you complete this list before you install the macOS High Sierra beta.

How to Fix macOS High Sierra Beta Battery Life Problems

We aren’t seeing massive macOS High Sierra battery life problems, at least not widespread. If you do run into issues there are some things you can try.

Next, try turning down your screen brightness, and updating all of your apps. These are common culprits for bad battery life.

If possible use Safari instead of Chrome or Firefox while using the beta. You can hold your mouse above the battery indicator to see what apps are using a lot of battery. Close these apps to get better battery life. Sometimes even restarting the app will help.

If you are using a third-party module, you may be out of luck, but that should be a minority of users.

If your Mac is slow right after installing the macOS High Sierra beta, you simply need to wait for processes to complete.

When your Mac is still slow after a day, you should try restarting your Mac and updating your apps.

    Well I anxiously awaited High Sierra’s release Sept. 25 and installed it. Sorry to say it was macOS high disappointment.It was a fresh install on a Macbook Pro A1278 mid 2012 256gb SSD 8gb memory. Previously Sierra used to startup in 10 seconds. High Sierra took close to 2 minutes and that was on the SSD. I wonder how long it would take on a normal HDD. Very disappointed, I think Apple’s done a Windows 8 here.
