Most Common macOS Big Sur Issues: What to Expect

Fall is an important period of the year for Apple. We get new devices. This year, Apple is expected to introduce iPhone 12, high-end over-ear headphones, and HomePod during the October 2020 event. But Mac users have something else to hope for: an upgrade to their operating system. After many years of expectations, the company finally introduced a Mac OS 11 under the name Big Sur.

It’s supposed to be great! We’ll get an even safer, more convenient environment to work in. We still don’t know the official release date, but it will be at some point this fall. The new Mac OS has received tons of praise based on the announced features and experience from beta testers. Now, let’s focus on another aspect: should users expect any issues with it?

All operating system upgrades come with small or more serious issues that frustrate users. What do beta testers say about the new macOS? We’ll discuss the most common problems, but we’ll also suggest ways how to fix macOS Big Sur issues.    

Common Issues with Mac OS 11: What to Expect and How to Fix the Problems

  1. Problems with the USB 2.0 Connection

This issue was known with macOS Catalina. Beta testers inform that it occurs with the new macOS 11 as well. After they upgrade, some of them aren’t able to connect mice, keyboards, and other USB 2.0 accessories to their computers. 

Everyone expects Apple to fix the issue before the official launch of the new Mac OS. In case you experience it, here’s what to do:

  • Restart your computer. After that, try reconnecting the devices again. If the problem persists, try restarting again. It’s the only fix to try until Apple solves the issue with an update.    
  1. Files Lost During the Big Sur Upgrade

This issue may occur with any new Mac OS upgrade. Important data, such as documents and photos, might be gone when you enter the new environment after the updating process. It doesn’t usually happen, but it’s possible. 

That’s why Apple warns you to back up your important files before starting the process. That’s a way to prevent loss from occurring. 

There’s a simple fix to this issue:

  • You’ll simply access the data on the cloud or on the external drive that you used for backup. 
  • If you didn’t back up your files and now they are gone, you can try a third-party recovery tool to recover them. 
  1. Problems with Third-Party Apps 

Apple update issues with applications were common with macOS Catalina. It suddenly ditched all 32-bit apps, so they stopped working. Now you only have 64-bit applications on your computer, so you don’t expect the same headaches with the new upgrade. However, beta testers report that some of their third-party apps unexpectedly quit after the Big Sur update. 

  • Make sure all your applications are up-to-date. If you’re running an older version, it might not be compatible with the new macOS.
  • Check what the developers of that particular app say. They might be working on a solution, which will be available with the next app update.  
  1. Wi-Fi Connection Issues 

After the upgrade, you may experience one of the most annoying Macintosh problems: for some mysterious reason, your computer fails to connect to the Wi-Fi network. How do you solve this?

  • Open Network under System Preferences, and access the Wi-Fi settings;
  • In the bottom right corner, you’ll see the Advanced settings; access them;
  • Uncheck all the boxes to remove the known Wi-Fi connections;
  • Restart your computer;
  • After this, scan your network environment and try connecting to your network (you’ll be required to enter a password).
  1. Battery Drains Too Fast after the Update

The new operative system is promoted as a battery-savvy one. Safari, in particular, is becoming much less burdening to the battery’s life. Beta testers didn’t expect Apple update issues regarding battery life, but some reported the hassle. The upgrade could make your battery drain faster than before. What’s the fix?

  • Find the app that’s causing the issue. You’ll get this info if you access Energy under Activity Monitor. Here, you’ll see what apps have the biggest impact on battery consumption. If there’s a problem with a particular app, check if it’s been updated. If everything looks fine with it but it’s still draining the battery, consider an alternative.
  • Check your battery’s lifespan. Has it been through too many cycle counts? You can get this info in Power, under Hardware in System Report.     
  1. The OS Running Slow after an Update

The download will be slow, so it’s something you can expect. Upgrades are heavy downloads, and we experienced the same issue with Catalina and all previous ones. According to beta testers, Big Sur is even slower during the download than its predecessors. It’s best to do the upgrade during a weekend or overnight, when you won’t need your computer for work. This is not a bug and there’s no fix or it; you’ll just have to wait for the large file to download. 

However, some beta testers report on another issue, which seems more serious: their computers are running slower than usual after the installation. Is there a fix to this?

  • If your system is cluttered, that might be the problem. Start by removing all apps and processes that you don’t need to run. 
  • Try disabling login items, since they are known to affect the computer’s performance in a negative way. You can find the login items under Users & Groups in System Preferences. You don’t need all those apps to launch at login, so remove most of them.  
  1. Startup Problems after Upgrading

Your computer will automatically restart after installing the new operating system. This is when some beta testers experienced one of the most serious Apple update problems: their computers failed to turn on. The loading screen is stuck and no matter how long they wait, the computer won’t start working. 

  • A force restart is the first thing to try during such an issue. To do this, press and hold the power button until you see the restart option. 
  • If you don’t see any improvements, restart the computer to Safe Mode. From there, you can reinstall the new macOS. This solution worked for most beta testers. 

Will You Upgrade to Big Sur?

Here’s the truth: the new operating system is expected to be outstanding. It will make our Macs faster, more convenient, and more responsive. Most users won’t experience any issues with the upgrade. Apple is working on the problems that beta testers report, and that’s why we’re still waiting for the official release. Hopefully, the transition process will be seamless for all Mac users.
