Do not unplug, power off, or move your Mac during the upgrade. It could result in data loss or damage.

The macOS Big Sur installer is about 12.5 GB. Note if your home Internet plan has a data cap or bandwidth limits it may be difficult to to upgrade.

You may need to free up disk space in order to complete the upgrade. Common places to delete files from include...

  1. Applications. Large unused Applications like iMovie, GarageBand, Keynote, Pages, Numbers, etc. Note most users do not have permissions to remove Applications themselves. Tech can help here.
    1. You may have to remove common apps and reinstall once the upgrade is complete. (i.e. Word, Excel, etc.)
  2. User home folder. Desktop, Documents, Downloads. Delete files or move to Google Drive.
  3. Other application support and cache folders. Primarily ~/Library/Application Support for apps which are no longer installed.
