# ProMacTools

> Small, focused Mac utilities: per-app volume control, a DevTools-style network monitor and an automatic key presser. Pay once, no subscription.

All apps: native macOS (Swift), universal (Apple silicon + Intel), 14-day free trial, one-time purchase in USD, license for 3 Macs, free updates, 14-day refund, no tracking.

## Apps
- [NetScope](https://promactools.com/netscope/): NetScope shows every HTTP, HTTPS, DNS, QUIC, TCP and UDP connection on your Mac, which app made it and how long it took, in a view that works like the Chrome DevTools Network tab. One-time purchase, $19.99.
- [App Volume Mixer](https://promactools.com/volume-mixer/): App Volume Mixer lets you set the volume of each app on your Mac separately, like the Windows Volume Mixer. Mute noisy apps, boost quiet ones up to 400%, right from the menu bar. One-time purchase, $9.99.
- [AutoKey](https://promactools.com/autokey/): AutoKey presses any key on your Mac automatically at the interval you choose — in the app you pick, even when it is in the background. Keep remote desktop sessions and dashboards from timing out. One-time purchase, $7.99.
- [ProMacTools Bundle](https://promactools.com/pricing/): All three apps — NetScope, App Volume Mixer and AutoKey — with one license key each. $24.99 one-time.

## Guides
- [How to Change the Volume of Individual Apps on Mac](https://promactools.com/guides/per-app-volume-mac/): macOS does not have per-app volume control built in: the volume keys and Control Center change the whole Mac. To set a different volume for each app, install a per-app mixer such as App Volume Mixer, which adds a slider and mute button for every app that plays sound in the menu bar.
- [Why Does My Mac Lower Other Apps' Volume During Calls? (And How to Fix It)](https://promactools.com/guides/mac-lowers-volume-during-calls/): When an app turns on Apple's voice processing for a call or intercom (FaceTime, Zoom, Teams, Webex, Discord and many camera apps such as ImouLife), macOS automatically lowers ('ducks') the sound of every other app so voices are clearer. There is no system setting to turn it off. You can end the call, quit the app, stop it from using the microphone, or raise the other apps with a per-app volume mixer to compensate.
- [How to See Which Apps Are Using the Internet on Mac](https://promactools.com/guides/see-which-apps-use-internet-mac/): Open Activity Monitor and choose the Network tab to see how much data each process sends and receives. For the servers each app connects to, run nettop or lsof -i in Terminal. For a full, searchable view of every connection and request per app, use a network monitor such as NetScope.
- [How to Monitor HTTP Requests From Any App on Mac (Not Just the Browser)](https://promactools.com/guides/monitor-http-requests-mac/): Browser DevTools only show requests made by the page you are inspecting. To see requests from any app on a Mac you can either route traffic through a debugging proxy (which can decrypt HTTPS but needs certificate setup and only sees apps that use the proxy) or capture packets with a network monitor such as NetScope, which sees every app without configuration and shows full plain-HTTP requests plus server names and timing for HTTPS.
- [How to Automatically Press a Key on Mac at an Interval](https://promactools.com/guides/auto-press-key-mac/): You can press a key automatically on a Mac with an AppleScript loop run from Terminal (osascript using System Events key code), or with an app such as AutoKey, which lets you choose the key, the interval and the target app, and waits while you are typing. Both need Accessibility permission.
- [How to Keep a Remote Desktop or Windows App Session From Disconnecting on Mac](https://promactools.com/guides/keep-remote-desktop-session-active-mac/): Remote Desktop and Windows App sessions are usually disconnected by an idle timeout on the remote computer or server, not by your Mac. Keeping your Mac awake with caffeinate does not stop it. Either change the idle-timeout policy on the remote side, or send a harmless key press (for example Shift or F15) to the Windows App window every few minutes with a tool like AutoKey.
