Why do people downgrade Apple OS?

Downgrading your Apple operating system (iOS, macOS, or iPadOS) can have several potential advantages, although it’s worth noting that Apple does not officially support downgrading, so the process can be complex and may void your warranty. Here are a few potential advantages:

1. Compatibility: Newer operating systems may not be compatible with older hardware or apps. Downgrading can help if you find that your device is slower or less stable after updating to a newer OS version.
2. Performance: Older devices might struggle with the demands of newer operating systems, leading to slower performance. Downgrading to an older OS can make your device run more smoothly.
3. Battery Life: Newer OS versions can sometimes be more power-hungry. If you find that your battery life is significantly reduced after an update, downgrading might help.
4. App Compatibility: Sometimes, after updating, certain apps may not work correctly or at all. Developers might not have optimized their apps for the latest OS version, causing compatibility issues. Using an older OS version might resolve these problems.
5. Jailbreaking/Rooting: For users who jailbreak their iPhones or root their Android devices, downgrading can be necessary to maintain the jailbreak or root access. This allows for customization and the installation of apps that are not approved by Apple or Google.
6. Customization: Older OS versions might offer more customization options. Apple tends to restrict customization features in newer updates, so users who prefer a high level of customization might choose to stick with an older version.
7. Security Vulnerabilities: While newer OS versions generally have better security features, they can also contain new vulnerabilities. If you’re using an older device that doesn’t receive security updates anymore, downgrading to an OS version with known security measures might be preferable.

It’s important to weigh these advantages against the potential risks and difficulties associated with downgrading. Always make sure to back up your data before attempting to downgrade, as the process usually involves wiping your device clean. Also, be aware that downgrading might introduce security risks, especially if you’re reverting to an older version with known vulnerabilities.
