Apple has officially stopped signing iOS 18.5 as of 5 August 2025, following the recent release of iOS 18.6. This means users who have already upgraded can no longer downgrade their iPhones or iPads to the previous version.
Apple typically discontinues support for older iOS versions shortly after a new update is rolled out. With iOS 18.6 now the latest supported version, any attempt to revert to iOS 18.5 will be blocked.
This policy affects both iPhones and iPads, aligning with the corresponding iPadOS update.
What happened
This move is standard practice for Apple and is aimed at ensuring users remain on the most secure and stable version of iOS. For users in Malaysia, especially those managing devices for work or school, it is important to consider this before upgrading.
Once your device is updated to iOS 18.6, there is no official way to return to iOS 18.5—even if issues arise.
Although some users prefer older versions for performance reasons or compatibility with specific apps, Apple’s update policy prioritises security and consistency across its ecosystem.
Any bugs or problems encountered in iOS 18.6 will likely be addressed in upcoming patches or minor updates.
Why Apple ends signing older versions
Apple generally stops signing older iOS versions within days or weeks after releasing a new update. This short window discourages fragmentation of the iOS ecosystem and reduces the risk of exploits or vulnerabilities found in previous releases.
What you should do
Users who have not yet updated to iOS 18.6 are advised to back up their devices before proceeding. If issues arise after updating, the only option is to report them to Apple and wait for the next update.
Plan before updating your device—because once Apple stops signing an iOS version, there is no turning back. Are you already on iOS 18.6 or still holding off?
