Core Viewpoint - The article discusses the process and considerations for downgrading from the beta versions of iOS 26, iPadOS 26, and macOS 26 back to previous stable versions, emphasizing the importance of data backup before upgrading to beta versions [1][2][20]. Group 1: Downgrade Process - Downgrading from beta versions requires significant effort and may result in data loss, as devices will be restored to factory settings [5][12]. - Users must ensure that they have backed up their data before attempting to downgrade, as the downgrade process does not retain any data [8][10]. - For iPhone and iPad, the downgrade process involves connecting the device to a PC or Mac, entering recovery mode, and downloading the appropriate firmware [9][21]. Group 2: Backup Methods - iPhone and iPad can be backed up using either a computer for full backups or iCloud for cloud backups, with the latter typically being enabled by default [13]. - Mac users should utilize "Time Machine" for backing up data before upgrading to macOS 26 [13]. - Apple Watch backups are automatically included in the iPhone backup, and users should ensure their iPhone is backed up to retain Apple Watch data [15]. Group 3: Downgrade Limitations - Downgrading is only possible while Apple is still signing the older firmware versions, which typically lasts for about a month after a new version is released [29][30]. - Users cannot downgrade to a version for which Apple has stopped signing, making it crucial to check the signing status of firmware [32][33]. Group 4: Special Considerations for Devices - The downgrade process for Mac is slightly more complex but manageable for users following the outlined steps [34]. - Apple Watch downgrades cannot be performed by users at home and must be done through official channels, such as visiting an Apple Store [45][46].
