Overview

Proxifier routes the traffic of individual macOS apps through a proxy, so you do not have to change system-wide network settings or touch every application's own configuration. This tutorial connects Dataimpulse residential proxies (HTTP or SOCKS5, pay-as-you-go) to Proxifier on macOS, verifies the connection from Terminal first, and then scopes proxying to only the apps you choose.

Every value used below comes from your Dataimpulse dashboard: the proxy host, port, username, and password. Dataimpulse is a suggested provider for this workflow because it offers residential and mobile IPs over HTTP and SOCKS5 on a pay-as-you-go model, which suits short tests and staged rollouts. Rotation, session behaviour, and any targeting options depend on your plan, so treat the dashboard as the source of truth whenever a setting does not match this guide.

Before you start

A Dataimpulse account with available balance.
Your proxy host, port, username, and password from the dashboard. Record both the HTTP and the SOCKS5 endpoint if your plan provides them.
Proxifier for macOS installed, and an admin account so you can approve any system component prompt.
Terminal access for the verification steps.
A note of your normal public IP address, so you can tell whether proxying actually worked.

Choose the right proxy type in Proxifier

Proxifier type	Use it when	Notes
HTTPS	The app only speaks HTTP/HTTPS	Proxifier tunnels HTTP requests through CONNECT; this is the usual choice for browsers.
SOCKS5	The app or tool works better at the socket level	Use it only if your Dataimpulse dashboard shows a SOCKS5 host and port.

If both endpoints exist, start with HTTPS. It is the easier one to troubleshoot and covers most browser-driven work.

Steps

Copy your credentials from the Dataimpulse dashboard. Note the host, the port for the protocol you picked, the username, and the password. Copy and paste rather than retyping, because a single wrong character produces the same error as a wrong password.
Verify the endpoint in Terminal before opening Proxifier. Failing fast here separates a credential problem from a configuration problem:

curl -s -x "http://USERNAME:PASSWORD@HOST:PORT" https://api.ipify.org

For a SOCKS5 endpoint, use the SOCKS5 scheme and let curl resolve DNS through the proxy:

curl -s -x "socks5h://USERNAME:PASSWORD@HOST:PORT" https://api.ipify.org

The command should print an IP address that differs from your normal one. If your username or password contains characters such as @, : or /, URL-encode them in the curl URL (@ becomes %40, : becomes %3A). Encode them only for curl; enter them as plain text in Proxifier.

Install Proxifier on macOS and approve any system component prompt that appears. Proxifier needs that approval before it can intercept app traffic.
Add the proxy in Proxifier. Open Profile → Proxy Servers…, click Add, and fill in:
- Address: the Dataimpulse host from your dashboard.
- Port: the port that matches the protocol you chose.
- Protocol: HTTPS or SOCKS5, matching the port.
- Username / Password: the credentials from your dashboard.
Then click Check to run Proxifier's built-in connectivity test. A passing check means the proxy is reachable and the credentials are accepted.
Define proxification rules. Open Profile → Proxification Rules…. Set the Default rule to Direct so that nothing is routed by accident, then add one rule per app you actually want proxied (for example Safari, Chrome, or a command-line scraping tool). Match the rule by application name and set its Action to the proxy you just added. Keep specific app rules above the Direct default and use the arrow buttons to reorder them.
Confirm with a real request. Open one of the proxied apps, load an IP lookup page, and compare the result with the IP you recorded earlier. Then open Proxifier's log or connection view to confirm that the app's connections list the Dataimpulse proxy as their target.
Understand how your endpoint rotates. Repeat the Terminal request a few times and watch the reported address:

for i in 1 2 3; do
  curl -s -x "http://USERNAME:PASSWORD@HOST:PORT" https://api.ipify.org
  echo
done

If you see the same address repeatedly, your plan may be using a session-based rotation policy rather than rotating on every request. Check the dashboard before assuming rotation is broken.

Keep credentials out of your shell history by storing the proxy URL in a variable for the current session:

export DI_PROXY="http://USERNAME:PASSWORD@HOST:PORT"
curl -s -x "$DI_PROXY" https://api.ipify.org

Troubleshooting

Symptom	Likely cause	Fix
`407 Proxy Authentication Required`	Wrong or expired credentials	Re-copy the username and password from the dashboard and update the proxy entry.
curl works, Proxifier does not	Rule set not matching the app, or the Default rule still routes Direct	Check the application name in the rule and confirm the rule sits above the default.
Browser still shows your real IP	A browser extension or macOS network proxy setting is overriding Proxifier	Disable conflicting proxy extensions and clear any manual HTTP/HTTPS proxy in System Settings → Network.
Connection refused or timeouts	Port and protocol mismatch, or the endpoint is temporarily unavailable	Re-check that the port belongs to the protocol you selected; try the other protocol if your plan offers one.
Proxifier stops intercepting after a macOS update	The system component approval was reset	Re-approve the component when prompted, then restart Proxifier.
Everything is very slow	Distant exit node or a large distance between you and the proxy	Test with a smaller, single request to confirm it works, then adjust your plan or endpoint choice in the dashboard.

Summary

Verify Dataimpulse credentials with curl before configuring Proxifier, so credential errors and configuration errors never get mixed together.
Add the proxy under Profile → Proxy Servers… using the protocol that matches your port, and confirm it with Proxifier's Check button.
Set the Default rule to Direct and add per-app rules under Profile → Proxification Rules… so only the apps you choose are proxied.
Confirm success by comparing the exit IP with your normal address, then repeat requests to learn how your endpoint rotates.
