About Apple threat notifications and protecting against mercenary spyware
Apple threat notifications are designed to inform and assist users who may have been individually targeted by mercenary spyware attacks.

Apple threat notifications are designed to inform and assist users who may have been individually targeted by mercenary spyware attacks, likely because of who they are or what they do. Such attacks are vastly more complex than regular cybercriminal activity and consumer malware, as mercenary spyware attackers apply exceptional resources to target a very small number of specific individuals and their devices. Mercenary spyware attacks cost millions of dollars and often have a short shelf life, making them much harder to detect and prevent. The vast majority of users will never be targeted by such attacks.

According to public reporting and research by civil society organizations, technology firms, and journalists, individually targeted attacks of such exceptional cost and complexity have historically b

If your iPhone or iPad is running slow
Try these tips if your iPhone or iPad freezes or has performance issues.

Check your network conditions
Apps often need an internet connection, and slow performance can occur due to network congestion or when a device reconnects to cell towers while moving. Even with a strong signal, you might need to wait, try a different location, or use Wi-Fi. Contact your carrier if cellular data issues persist across multiple locations.

Use Low Power Mode to save battery life on your iPhone or iPad

TCP and UDP ports used by Apple software products
These are some of the common TCP and UDP ports used by Apple products, such as macOS and iCloud. Many are well-known, industry-standard ports.

This list and the list of hosts and ports required to use Apple products on enterprise networks are updated periodically.

If you’re configuring a firewall or similar access-control scheme, port-watching software can help you decide how to do it. Be aware that some products can use different ports and services, including ports and services not documented here. And some services, such as those used for a VPN, can use multiple ports. If your firewall doesn’t specify a port's type, it probably configures that port for both TCP and UDP. (The application firewall in macOS controls access by app, not by port.)
