Common Questions

PIDKill can't kill a specific process

System processes require elevated permissions. PIDKill will prompt you to enter your administrator password to kill them. A very small number of processes are protected by macOS System Integrity Protection (SIP) and cannot be killed even with admin privileges — this is by design.

A process keeps coming back after being killed

Some daemons have watchdog services that respawn them. Use PIDKill's auto-scan feature (e.g. scan every 5 seconds) to persistently kill respawning processes. PIDKill will keep killing them as fast as they restart.

How do I transfer my settings to a new Mac?

Open Settings (gear icon) → Export Targets. This saves your target list as a JSON file. On your new Mac, use Import Targets to load it.

How do I activate my license?

After purchasing on Gumroad, you'll receive a license key via email. To activate: click PIDKill in the menu bar → Activate License → enter your key → click Activate. Done!

How many Macs can I use with one license?

One license can be activated on up to 2 Macs simultaneously — for example, your MacBook and your desktop Mac. To move a license to a different device, deactivate it on the old device first, or email us for help.

How do I transfer my license to a new Mac?

Open Settings (gear icon) → Copy License Key to copy your key to the clipboard. On your new Mac, activate PIDKill with the same key. Each license supports up to 2 devices. If you no longer use the old Mac, you can also deactivate it first via Settings → Deactivate This Device.

Can I get a refund?

PIDKill offers a 3-day free trial with full functionality so you can evaluate the app before purchasing. Because of this, all sales are final and no refunds are provided after purchase. Please make sure PIDKill meets your needs during the trial period.
