Apple's Post-Quantum Cryptography Support in iOS 26, iPadOS 26, macOS Tahoe 26, and visionOS 26

2025-06-17

iOS 26, iPadOS 26, macOS Tahoe 26, and visionOS 26 now include support for post-quantum cryptography, negotiating quantum-safe key exchange (X25519MLKEM768) via TLS 1.3. This enhances security by preventing future quantum computers from decrypting TLS traffic. However, some legacy servers may fail to connect due to oversized ClientHello messages. Apple provides a temporary compatibility mode (`defaults write com.apple.network.tls AllowPQTLSFallback -bool true`) as a workaround, but this is a temporary solution.

Excel's MAP Function: Functional Mapping of Array Elements

2025-04-04

Excel's MAP function offers a powerful way to process arrays. It transforms each element in an array using a custom LAMBDA function and returns a new array. You can input multiple arrays, and the LAMBDA function will calculate the elements at corresponding positions. This makes batch data processing concise and efficient; simply define the calculation formula, and the MAP function automatically completes the mapping of all elements.

Migrating Apple Account Purchases: A Comprehensive Guide

2025-02-12

This guide details how to migrate apps, music, and other purchased content from a secondary Apple Account to a primary one. Several prerequisites must be met, including: both accounts must be distinct, have two-factor authentication enabled, be set to the same region, and the secondary account must have a zero balance with no outstanding rentals or pre-orders. The migration process occurs within your iPhone or iPad settings. Afterwards, the secondary account can no longer be used for media and purchases. The guide also lists various reasons why the migration might fail, such as incompatible account types or unusual account status, making it a very helpful resource.
