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.) | |

If your iPhone or iPad gets too hot or too cold | |
Learn about the operating temperatures and temperature management of iPhone and iPad. | |
Use and store your device in these temperatures | |
Use iOS and iPadOS devices where the ambient temperature is between 0º and 35º C (32º to 95º F). Low- or high-temperature conditions might cause your device to change its behavior to regulate its temperature. Using an iOS or iPadOS device in very hot conditions can permanently shorten battery life. | |
Store your device where the temperature is between -20º and 45º C (-4º to 113º F). Don’t leave your device in your car, because temperatures in parked cars can exceed this range. | |
If your device gets too warm or too cold, certain features might become temporarily disabled. In extreme conditions, your device might become temporarily disabled. |
