macOS Big Sur is a revolutionary update to Apple’s operating system. It brings a number of new abilities to Mac, including a significant update to Safari, a redesigned user interface, and lots of tweaks promised to increase, power efficiency, performance, and security. Yet, it comes with its own issues just like any new operating system.
In this article, you find the list of potential problems with macOS Big Sur and tips on how to fix them.
macOS Big Sur Download Problems
Sometimes, the new system fails to download, and that may happen because of a number of reasons. First of all, you need to check the Internet connection. Besides, the download may fail because the server is very busy or down, so you need to visit Apple’s system status page to make sure everything is alright on Apple’s end.
Next, you should check out how much storage space you have on your Mac. Click on the Apple logo in the top left corner, then click on About this Mac, and select the Storage tab. Make sure you have a least 16GB free. If not, you’ll need to move some files to an external drive or to the cloud or delete them to free some disk space.
Installation Problems with macOS Big Sur
If you have successfully completed the download, but the macOS Big Sur operating system won’t install, you should try these things.
The first thing you should do is to ensure that your Mac is compatible. You can find a list of Macs that support Big Sur on Apple’s website. If your Mac is compatible, but you don’t see the prompts to continue installation, you should search for a file called “Install macOS 11” in the application folder. You need to double click the file to start the installation process.
You can also reboot your Mac in Safe Mode by holding Shift as you reboot it. That can help fix the “gateway timed out” error. Besides, you may reset NVRAM, and then try to install Big Sur again.
macOS Big Sur Problems with Slow Performance
Perhaps, it’s the most common problem because the new operating system puts more pressure on your system resources. Once you install macOS Big Sur, you may notice that your machine is running slower than before.
First of all, you should make sure that all software and apps are updated, and you use their latest versions. If you have any third-party apps, make sure that they support your new OS. If any of the apps has issues with Big Sur, this may be one of the reasons why your device is running slower. Other things that may slow down your Mac are login items running in the background. You need to stop them opening at startup. Choose System Preferences, then click Users & Groups, choose Login Items, and click the “-“ sign after you’ve choose the apps. Besides, you should check Activity Monitor to find out which processes are taking up a lot of RAM or CPU and force-quit them.
