Description
¡Hola! Bonjour! Hallo! USB Connection Information is now more accessible than ever, with support for 16 languages, VoiceOver, and Contrast Mode.
USB Connection Information is the essential menu bar utility that instantly reveals the true performance of every USB, Thunderbolt, and power connection on your Mac. It’s the perfect tool for professionals, tech enthusiasts, and anyone who wants to verify their hardware is performing as advertised.
Is that new cable actually running at slow USB 2.0 speeds? Is your charger delivering the full wattage? With Connection Information, the answers are right in your menu bar.
KNOW YOUR HARDWARE
Instantly check crucial details for any connected device:
- Live Power Adapter Wattage: See the true power your Mac is receiving from its charger. (Battery powered devices only)
- Verify Connection Speed: Confirm data rates from 1.5 Mbps all the way up to 40 Gbps*.
- Identify USB & Thunderbolt Version: See plain-English names from USB 2.0 to 3.2, and Thunderbolt 1 through 4.
- See Device Power Draw: Check the wattage requested by each peripheral.
- Look Up Vendor & Product ID: Find the specific hardware identifiers.
- View Serial Number: Instantly access your device's serial number.
- One-Click Copy: Copy serial numbers and other details to your clipboard right from the menu.
* Please Note: Due to the way macOS and devices report their status, the app displays negotiated USB speeds up to 10 Gbps. For faster connections like Thunderbolt and USB4, the app shows an estimated maximum capability of your Mac's port. For the same reason, some purely USB4 devices that use protocol tunneling (like PCIe) may not appear in the device list.
INSTANT DEVICE AWARENESS
See a full list of connected USB and Thunderbolt devices the second you plug them in. Know exactly what’s connected without digging through system menus.
AUTOMATIC VENDOR IDENTIFICATION
Automatically identifies the manufacturer for over 90% of common consumer USB devices, turning cryptic vendor IDs into names you recognize.
CUSTOMIZE YOUR MENU BAR
Tailor the app to fit your workflow. Show a simple icon, the speed of your primary device, or a count of all connected peripherals.
EFFICIENT & PRIVATE
Built with modern SwiftUI for a lightweight footprint that won’t slow you down. Your data is never collected and never leaves your Mac.
Take the guesswork out of your hardware. Download USB Connection Information and get empowered.

Ratings and Reviews
Great App!
This app is so simple to use, I love it. I would love to see an option to let it fallback to the icon when no power source is connected, rather than having text saying “Connected/Not Connected” as I’d love to see it only for wattage when connected.
Developer Response ,
Thank you so much for the kind words and the fantastic review! I'm really glad you're finding the app simple and useful. That's an excellent suggestion for the menu bar display. I completely agree, that would be a much cleaner and more elegant implementation. I have updated the logic in the most recent update that matches your request. Suggestions like this are what help make the app better for everyone!
Perfect!
This app is great, it does exactly what it says it’s going to, and does it really well. It sits in the menu bar and provides the info as soon as any USB is plugged in. Doesn’t get in the way, and love that no subscription is required. Totally worth it

And thank you for highlighting the no-subscription model. I believe in providing great value with a single purchase, thrilled you feel it was totally worth it. Thanks again for your support!
