AltServer

What is AltServer?

AltServer is a Mac utility used with AltStore to install apps onto iPhone and iPad devices from a computer. It is designed for people who use AltStore’s alternative app distribution workflow and need a desktop companion on macOS. On a Mac, AltServer runs from the menu bar and lets you install AltStore to a connected device, refresh app signing, and support related device-management tasks. It is commonly used by iPhone and iPad users who want to keep AltStore and compatible apps available without relying on the App Store for distribution. Because it acts as the desktop side of that process, users will mostly interact with it when setting up AltStore, reconnecting devices, or performing refresh and maintenance steps.

Key features

• Install AltStore to a connected iPhone or iPad from your Mac
• Refresh app signing for AltStore-managed apps
• Run from the macOS menu bar for quick access to device actions
• Work with USB or local network device connections during setup and refresh
• Support device-focused maintenance tasks used by the AltStore workflow

Safety overview

Status: Mostly safe

AltServer is legitimate desktop software for the AltStore workflow, but it works by communicating with your iPhone or iPad and may request access or supporting components that are normal for device installation tasks. Use it only if you intend to manage AltStore on your devices, and download it from the official AltStore site. If you remove it, AltStore installation and refresh tasks from your Mac will stop working until it is installed again.

Recommendation: Keep AltServer if you use AltStore or need to install or refresh AltStore-managed apps from your Mac. If you no longer use that workflow, you can remove it without affecting macOS itself, though future AltStore setup or refresh actions will require reinstalling it.
