TaskExplorer from Objective See answers a simple question in unusual depth: what is actually running on this Mac right now? It lists every process live and shows how each one is signed, which libraries it has loaded, which files it has open and where it connects on the network. For anyone checking a suspicious process or learning how macOS works under the surface, it turns guesswork into plain evidence.

Key Features

  • Live process list that updates the moment apps start and exit
  • Code signing status for every process, from Apple signed to unsigned
  • Loaded dylibs, open files and network connections for any process you select
  • Optional VirusTotal checks flag known bad files in red, using your own free key
  • Built in assistant answers questions about what is running, on supported Macs

How to Download

  1. Download TaskExplorer using the button on this page and unzip the archive you receive.
  2. Move the app to your Applications folder, launch it, and approve its system extension when macOS asks.
  3. You can also Download from the official site to get it straight from Objective See.

System Requirements

TaskExplorer 3 needs macOS 14 Sonoma or newer on an Apple silicon or Intel Mac. The vendor offers an older version for Macs on macOS 11 to 13.

FAQs

Is TaskExplorer free?

Yes. Objective See offers TaskExplorer free of charge, like the rest of its Mac security tools.

Why does it need a system extension?

Version 3 uses the Endpoint Security framework from Apple to watch processes start and exit. macOS requires such tools to run as a system extension with Full Disk Access.

Does it send my files anywhere?

No files leave your Mac. If you add a VirusTotal key, only file hashes are sent for checking, never the files themselves.
