How to upgrade to macOS 11 Big Sur

macOS Big Sur 11: Upgrade Guide and Preparation

Starting from November 12, 2020, macOS Big Sur 11 will be officially released to the public. This article will guide you on how to upgrade and take advantage of its new features, including revolutionary design changes, Safari browser updates, more Catalyst apps, and enhanced privacy protection.

Upgrade preparation:

First, confirm that your Mac is compatible. Not all Macs can run Big Sur, and some older Macs may not be compatible even if they can run macOS Catalina. Please check if your Mac model is in the following list:

• MacBook (2015 models and later)
• MacBook Air (2013 models and later)
• MacBook Pro (2013 models and later)
• Mac Pro (2013 models and later)
• Mac mini (2014 models and later)
• iMac (2014 models and later)
• iMac Pro (2017 and beyond)

Secondly, check the storage space. The upgrade requires about 18.5GB of free space (about 12.5GB for a brand new installation). It is recommended to use tools such as CleanMyMac X to clean up the system junk files and free up more space.

Finally, back up your data. It is important to back up important data before upgrading. It is recommended to use backup tools such as Time Machine or Get Backup Pro to create bootable backups to ensure data security.

Upgrade method:

You can choose to install the developer beta version or the public beta version, or directly install the official version (available from November 12, 2020).

Is it worth upgrading?

Big Sur brings many improvements, including a faster Safari browser (with privacy reporting, personalized start pages and built-in translation), improved messaging apps (supporting inline replies and new Memoji), updated map apps (providing featured guides and new green routes), and a new iPad-style design (including a new control center, updated toolbar and full-height sidebar). Please evaluate whether you need to upgrade based on your own needs.
