You need at least 35.5 GBs of free space to instal macOS Big Sur.

The following screenshot is from the Big Sur upgrade page,


Copy items you do not need on a daily basis to an external drive.

Movies, images and music tend to take up the most space.

When you are certain they have copied over successfully then

you can delete them from your mac.

Only delete items from your Users/<Home> folder do not delete

items you do not understand, do not delete any items from

System or Library folders.


Before upgrading make a full back up of your Mac.


Check that third party apps you use have updates available for the new OS.

Check that your printers/ scanners etc have updated drivers and software available for the new OS.


Connect your mac to your router via cable rather than rely on WiFi.

Do not use your mac while it is downloading

and do not use any other devices that share the same internet connection.


If the App Store says ‘Open’ then it is detecting a previous download of the install app

go to the Applications folder locate Install macOS Big Sur.app.

Move it to the Trash, empty the Trash.

Restart, click on the link again, the App Store should say ‘Get' or 'Download'.


If you are considering upgrading to Big Sur be warned tit does not support 32bit apps.

Your Mac is probably running 32bit apps and these will need to be updated to 64bit apps,

some updates may be free, some may be paid. Use this app to discover which apps you have

are 32bit, https://www.stclairsoft.com/Go64/ then contact the developers of the software to see

if they are providing 64bit updates or alternatives.
