MacOS “Big Sur” Issues

Recently, Apple released their latest macOS upgrade “Big Sur”. Aside from the latest and greatest software upgrades and enhancements Big Sur has to offer, there is hidden issue IS&T would like to make all Chapman Apple users aware of. Before running the Big Sur upgrade install, it is vital that you check you available disk space. The reason being is that insufficient disk space (Less than 50 GB) has been known to cause the upgrade to stall and corrupt your hard drive. In most cases where the Big Sur upgrade stalls the hard drive will need to be erased and re-imaged. Any files (documents, photos, videos, etc.) that were not backed up on a back-up drive or cloud storage, prior to the upgrade, will be lost. Before upgrading your macOS to Big Sur, please make sure that you are using the available cloud storage services (OneDrive,Google Drive, Dropbox, etc) or an external backup drive to save your information from potentially being lost. It is also important to note that both macOS 10.14 Mojave and 10.15 Catalina are still fully support. So there is no rush to upgrade to Big Sur at this time.
