[Solved]Mac Starts to Prohibitory Symbol After macosBig Sur Update

macOS Big Sur will be the next version of Mac OS, announced at WWDC 2020. It is again named after the landscape in California but skips the macOS 10 version to macOS 11. According to the macOS Big Sur preview from Apple, the new features mainly sit in the new control center, interface and notification center as well as improved apps such as Safari, Messages and Maps.

However, the new OS doesn’t always bring good news. Here is a list of macOS 11 known issues and fixes. In this article, we will specifically discuss the Mac booting into a prohibitory symbol on the screen after macOS Big Sur update.

What does it mean when your Mac boots to a prohibitory symbol?

When a circle with a line cross it appears on your Mac’s monitor instead of a login screen or desktop, it is very likely that your Mac doesn’t support running macOS Big Sur. Even though the OS can be successfully downloaded on the startup disk, the relevant hardware is unable to install the OS nor launch it for use. It is a very typical problem people encounter when they update their Mac computers.

What Macs are compatible with macOS 11 Big Sur?

It is recommended to check the system requirements before you upgrade your Mac, especially before a major OS version upgrade. Some models can run macOS Catalina but are not necessarily compatible with macOS Big Sur.

macOS 11 Big Sur can be running on Macs including:

  • MacBook models from early 2015 or later
  • MacBook Air/Pro models from 2013 or later
  • Mac mini models from 2014 or later
  • Mac Pro models from 2013 or later
  • iMac models from 2014 or later
  • iMac Pro models

By checking the Mac’s hardware information, you can go to Apple logo and About This Mac to know your Mac model.

How to fix the prohibitory problem issue?

Now you know macOS Big Sur is not the right OS to run on your Mac, but how to get rid of the downloaded macOS 11 files and restore the Mac? Don’t panic. The steps are very easy.

Step 1: Boot your Mac into Recovery Mode.

You need to start or restart your Mac and immediately press down Command, Option and R keys together. Release the keys until you see a loading screen. The booting process will be a lot slower than usual. Then you will be led to the OS X Utilities or macOS Utilities window.

Step 2: Back up files from the Mac.

If you are afraid of data loss, you can use Target Disk Mode or data recovery software to get the important files off the Mac first.

Step 3: Reinstall OS

You can choose to format the hard drive first in Disk Utility and reinstall OS. Also, you can directly reinstall OS by selecting Reinstall OS X or macOS and clicking Continue. You just need to follow the wizard to finish the reinstallation.

Conclusion

Before you update to a newer OS, do remember to check the compatibility first in case you will boot to a prohibitory symbol during the installation. If the issue is happening, you can easily restore the Mac to a bootable state. macOS 11 Big Sur is a beta now and will be released to public in fall 2020, so it is recommended to upgrade after it is officially released if your Mac is compatible.

Do I need a VPN for my Android smartphone?

Most people use a virtual private network (VPN) to safely browse the internet while they are away from home. This allows you to bypass restrictions on region-specific content and websites. So, this is maybe something you also want to use on your smartphone.

There are several scenarios in which you could use a VPN, for example if you are connecting to a public (and unsecured) Wi-Fi network.

Of course, it sometimes happens that you do not have a laptop available, but you do carry a smartphone with you. In these cases, you can consider downloading an android VPN app for your mobile device.

Is it wise to download a VPN app?

The main reason for installing a VPN app on your Android device is internet security. If you use a Wi-Fi connection a lot, for example in the catering industry or on a holiday abroad, it is certainly advisable to use a VPN.

Public connections

Do you often connect to public Wi-Fi networks via your Android phone? It is wise to think about securing your data. There is so much information stored on your phone, from online account login credentials to personal financial information. Therefore, some extra security is always a good move.

A VPN ensures that your data is encrypted and nearly impossible for third parties to access, even if you are logged into a public network with questionable security features. This means, you couldn’t get closer to real online anonymity.

Which VPN app is a good option for my Android device?

There are a lot of VPN providers. Of course, you want a service where the developers have thought carefully about how smoothly the VPN service should work on your Android device.

NordVPN is extremely popular and has more than ten million downloads worldwide. The app contains almost all the features you would expect from a good VPN and is also very focused on security and privacy.

The ‘Double VPN’ technology offers an extra layer of security by sending your connection over two separate VPN servers. NordVPN also offers a zero logs policy. This means that your data will not be stored by the company.

Not unimportantly, the NordVPN app has an automatic kill switch. This means that access to the web with your device is immediately lost if the VPN connection is accidentally lost.

NordVPN is very user-friendly. If you connect to a Wi-Fi network, a connection is automatically made with the app. NordVPN also has good performance when it comes to speed and it offers a 24/7 live chat option.
