Microsoft will soon restrict editing capabilities within older versions of its Office suite—specifically those predating version 16.6—when used on Apple devices. Starting later this month, users with these older applications will be limited to view-only access for documents on Macs and iOS/iPadOS. The change stems from updates to Apple’s operating systems that impact the older Office versions’ compatibility. Microsoft cites security and reliability concerns as driving factors behind the decision, noting the older apps haven’t been updated to leverage modern security features. Users are encouraged to upgrade to the latest version of Microsoft 365 to maintain full editing functionality. The company states that the most recent Office apps are not affected by these limitations and will continue to function normally on Apple platforms. This move impacts users who have not regularly updated their Office subscriptions.
