Apple Watch Series 8 is no longer supported — it has passed its end of life date (September 14, 2026). No further security patches will be issued. Upgrade to a supported version or obtain extended lifecycle support.

Question 3

Accepted Answer

Apple Watch Series 8 reached (or will reach) end of life on September 14, 2026. After this date, no security patches or bug fixes are issued by the vendor.

Question 4

What are the security risks of running Apple Watch Series 8 after end of life?

Accepted Answer

After end of life, the vendor's standard support for Apple Watch Series 8 ends, so newly discovered vulnerabilities may never be fixed unless a paid extended support option covers that version. Auditors ask about it too: PCI DSS requirement 12.3.4, for example, calls for a yearly review of vendor end-of-life announcements with a remediation plan approved by senior management.
