Apple says testing missed flaws in new encryption designed to protect against future attacks from quantum computers, so it turned to mathematical proofs to make sure the code works correctly before wider rollout. Apple services my be transitioning to post-quantum cryptography. New research and source code published May 22 detail how Apple verified parts of its post-quantum cryptography stack. The research argues conventional software testing is good, but no longer provides sufficient guarantees for encryption systems used across more than 2.5 billion active devices. The effort centers on corecrypto, Apple's low-level cryptographic library used across iPhone , iPad, Mac , and other platforms. Future quantum computers could eventually break many of today's public-key encryption systems, hence the effort. Technology companies are racing to replace older encryption methods before practical attacks become possible. Continue Reading on AppleInsider | Discuss on our Forums
Apple plans to hold an Apple Watch Activity Challenge to celebrate Global Running Day on Wednesday, June 3. To complete the challenge, Apple Watch owners will be required to record a running workout of at least 5K on Global Running Day. On June 3, the world runs as one. This Global Running Day, record a running workout of at least 5K (3.1 mi) to earn this award. Use the Workout app or any app that records workouts to Health. As a reward, Apple Watch owners can unlock a dedicated award in the Fitness app, plus animated stickers that can be used in the Messages app. Apple has been celebrating Global Running Day since 2024, and it comes after the April 2026 Earth Day and International Dance Day Activity Challenges .

Apple's iOS 26.6 update appears to add new wording around blocked contact limits, though it is unclear if the actual limits have changed. Code in the beta suggests users will get a warning if they exceed the maximum number of blocked contacts. "You've reached the maximum number of blocked contacts. To block additional callers, remove a blocked contact in Settings," reads the alert, which is titled "Blocked Contacts Limit Reached." Based on discussions on social media and Apple's Support Communities, some users have been unable to block additional contacts after hitting a 20,000 limit. Other people have mentioned running into issues after 8,000, and some have experienced issues with even fewer phone numbers blocked. Apple does not offer documentation on blocking limits. With limits in the thousands at least, it's unlikely most people have had blocking problems, though a person who is blocking spam callers regularly could eventually hit a cap. iOS 26.6 might make it clearer when a limit has been reached, and what to do about it. Removing older blocked contacts is the solution, which can be done by going to Settings > Apps > Phone > Blocked Contacts. There is no bulk unblocking tool, and the easiest way to remove a contact is to swipe left on each entry. Alternatively, you can select Edit, tap on the red minus button next to each contact, and choose the unblock option. iOS 26 added an Ask Reason for Calling option that sends calls from people who aren't in your Contacts directly to voicemail, which is an easier option for spam call management than blocking phone numbers. With the feature turned on, a caller can state their reason for calling and the person receiving the call can decide whether to pick up. Alternatively, all calls from unknown numbers can be silenced and sent to voicemail with no alert using the Silence option. Missed calls and voicemails from unknown callers can also be filtered into a separate Unknown Callers list in the Phone app. Some carriers also offer a separate spam detection option that can send calls from known spammers to the Spam list. Apple seeded the first beta of iOS 26.6 to developers today, and the software may soon be made available to public beta testers. A public release is likely several weeks away. So far, there are no other known features in iOS 26.6.
