How to find out if your Apple Mac computer can run MacOS Big Sur.

First simply review the Apple MacOS Big Sur system requirements. The Apple Mac age and how much memory is installed is a key factor. Below are the official Apple MacOS Big Sur system requirements for a Apple Mac computer to support Apple MacOS Big Sur.

Make an Apple Mac Time Machine backup.

The Apple advice is very clear make a complete and full Apple Time Machine backup before upgrading to Apple MacOS Big Sur, even if you are using the Apple iCloud an Apple Mac Time machine backup is recommended.

Review 32-bit code and remove any 32-bit Mac applications.

Review the applications which you are using on your current Apple Mac computer. Any 32-bit applications will not work, for example Microsoft Office 2011 for Mac will not work with Apple Mac OS Big Sur so a paid upgrade to Microsoft Office 365 is needed or Office for Mac 2019.

Most of the well-known Apple Mac applications like Dropbox, Skype, Zoom, Google Chrome, Microsoft OneDrive have newer versions that with Apple MacOS Big Sur.

The Apple MacOS has a built-in tool to show if 32-bit applications are installed.

Apple has told all of the Apple Mac software developers to get ready for MacOS 32 bit to MacOS 64-bit technology since 2006, so in 2020 there is no excuse for a software developer not to support MacOS Big Sur with a new 64-bit version of their application.

Apple MacOS Pre-Installed applications.

All of the Apple MacOS pre-installed applications are updated to 64-bit technology which includes Apple Mac Safari, Apple Mac Mail, Apple Photos for Mac, Apple Contacts, Apple Calendar, Apple Notes, Apple Reminders.

Adobe and Apple MacOS 64-bit support.

Adobe moved quickly to a subscription service many years ago, why, software copying, and software piracy, it was well known as Adobe Photoshop and Adobe Illustrator, Adobe In design was copied on a mass wide scale, so Adobe ended development on Adobe CS and started Adobe CC subscription service, to stop software copying and software theft.

The Adobe Photoshop and Adobe Illustrator and Adobe In design will have a Apple MacOS Big Sur supported Adobe CC version available with Apple MacOS Big Sur launch.

Get your Apple Mac ready for Mac OS Big Sur.

Most Apple Mac computers that are 2013, 2014, 2015 and newer support Apple MacOS Big Sur, apart from the Apple MacBook in which the Apple MacBook 2015 or newer is supported on Apple Big Sur. Sadly, the iMac 2012 is not supported, so Mac OS Big Sur will not install to an iMac 2012 that has been running MacOS Catalina 10.15.7.

Apple MacOS Big Sur Printer Support.

Most printers that work on Apple MacOS Mojave and Apple MacOS Catalina will work with Apple MacOS Big Sur. Printer vendors like HP, Cannon know that both home users and businesses either buy new Apple Mac computers or upgrade their Apple Mac computers, so most printers made in the past 5 years are more than likely to work with Apple MacOS Big Sur.

The Apple MacOS has built in printer drivers and scanner drivers to work with Apple MacOS Big Sur without having to install and additional software.

Remove 32-bit applications before upgrading to MacOS Big Sur.

The best way to remove a 32-bit application is to use the software vendors removal tool before upgrading to Apple MacOS Big Sur.

The Adobe software applications have removal tools which is the best way to remove all of the 32-bit applications and Adobe files from the Apple Mac computer.

Apple Mail and MacOS Big Sur.

The Apple Mac Mail application stores email messages in a database format, the Apple MacOS upgrade to Apple MacOS Big Sur will upgrade the Apple Mac Mail database to support Apple MacOS Big sur in most cases this is an automated process.

Again, it’s critical that a Apple Time machine backup is completed before upgrading to Apple MacOS Big Sur.

Perform Apple Mac Mail maintenance before upgrading to Apple MacOS Big Sur, for customers that have over 5000 emails or complex email setups it can be beneficial to make a backup of the Apple Mail database or export the critical email messages before upgrading to Apple MacOS Big Sur.

Apple MacOS Photos on Big Sur.

The Apple MacOS Photos for Mac Big Sur is now very stable vs the previous Apple iPhoto. The Apple iPhoto to Apple Photos for Mac is an automated process.

The Apple iPhoto application and Apple iPhoto Library file are redundant after upgrading to Apple MacOS Big Sur.
