PAW/RapidAPI application fails to launch on Apple Silicon Mac running macOS Monterey 12.6.2

Issue with API testing tool on updated macOS

After updating my Apple Silicon MacBook to macOS Monterey version 12.6.2, I’m experiencing problems with the PAW application (now known as RapidAPI). The software completely refuses to start up and shows no response when I try to launch it.

I’ve tested the same application on a coworker’s computer running macOS Monterey 12.6.1 and it works perfectly fine there. This makes me think the issue is specifically related to the 12.6.2 update.

What troubleshooting steps should I take to resolve this launch failure? Are there any known compatibility issues between this application version and the latest Monterey update? I need to get this working again for my API development workflow.

Had this same issue last month after updating to 12.6.2. Here’s what fixed it for me: reset the app permissions in System Preferences. Go to Security & Privacy > Privacy tab and remove RapidAPI from everywhere it shows up (Full Disk Access, Developer Tools, etc.). Once you’ve cleared it out completely, launch the app again - it’ll ask for permissions from scratch. The 12.6.2 update messed up permission databases for some apps. If that doesn’t work, check Console.app for crash logs when launching - they’ll show what’s actually breaking. This worked way better than clearing cache since it’s a permission issue, not corrupted data.

This looks like a code signing issue from the 12.6.2 security update. I hit the same problem with another dev tool after that update. Run codesign --verify --deep --strict /Applications/RapidAPI.app in Terminal to check for signature problems. If it fails verification, you’ll probably need to reinstall the whole app instead of just clearing cache. What worked for me was temporarily disabling Gatekeeper with sudo spctl --master-disable, launching the app once, then turning it back on with sudo spctl --master-enable. The 12.6.2 update really tightened security policies and broke apps that worked fine before.

i had the same issue! try clearing the app cache, it helped me. just delete the cache folder in ~/Library/Application Support/PAW and restart the app. also, check Activity Monitor for any hung processes, they could be causing it too.
