Field Report: Getting Rest Editor (app) to Work on macOS Monterey
Hey,
so yesterday I spent a few hours wrestling with Rest Editor (app) on my MacBook Pro M1 running macOS Monterey 12.6. I was trying to get a clean install for some quick REST API testing, and, as usual, the first launch was… dramatic.
I downloaded the build from OrchardKit, copied it into Applications, and double-clicked. macOS immediately hit me with the infamous Gatekeeper popup:
“Rest Editor.app can’t be opened because Apple cannot check it for malicious software.”
My first reflex was right-click → Open. Usually, that bypasses this kind of block. Nope. Nothing. The dialog flickered, then vanished, leaving me staring at the icon like it personally insulted me.
First Attempts
I thought maybe the download was corrupted. Re-downloaded the DMG, checked the checksum — fine. Launched from the mounted image, just to be safe. It opened once, then refused again once copied to Applications. At that point, it clicked: this wasn’t a broken file. macOS was keeping a quarantine flag on the app. Apple explains this behavior clearly here: support.apple.com/guide/mac-help/open-a-mac-app-from-an-unidentified-developer-mh40616/mac.
Next, I briefly considered disabling Gatekeeper globally with sudo spctl --master-disable, but that felt like using a sledgehammer for a paperweight. There had to be a cleaner fix.
The Real Fix
Terminal came to the rescue. I ran:
xattr -rd com.apple.quarantine /Applications/Rest\ Editor.app
Immediately, the app launched perfectly. No warnings, no cryptic errors — just a ready-to-go window for testing API calls. I saved this page for reference while debugging, which gave some practical hints on macOS system quirks and unsigned apps: https://planetgpa.com/developer/33684-rest-editor.html.
Then, a minor hiccup: exporting saved requests to Documents failed silently. No crash, no error, just nothing written. Classic macOS permissions issue. Quick fix: System Settings → Privacy & Security → Files and Folders, and I granted the app access to Documents. After that, exports worked flawlessly. Apple’s documentation on sandboxed access and notarization helped me understand why this happened: developer.apple.com/documentation/security/notarizing_macos_software_before_distribution.
Performance Notes
Once it finally launched, the tool ran smoothly. Importing large JSON collections was quick, and CPU usage stayed around 25–30% on the M1. The UI didn’t stutter, and no crashes occurred, which was a relief. On Intel machines, I’d expect slightly slower parsing on massive collections, but nothing that would break workflow.
I also checked the Mac App Store for an official notarized version: apps.apple.com search for Rest Editor. Nothing there, so the quarantine workaround is currently mandatory if you’re using the OrchardKit build.
What I Learned / Quick Checklist
Looking back, here’s how I’d tackle this next time:
- Download → copy to Applications
- Remove quarantine via Terminal
- Launch once
- Grant file/folder access if needed
- Test basic functionality
Following that order avoids re-downloads, failed launches, and silent export errors. Honestly, the time lost was mostly convincing macOS that the app wasn’t a threat.
Once past those initial hurdles, Rest Editor worked exactly as expected. Sending API calls, saving collections, exporting requests — all smooth. CPU load remained reasonable, and the UI was snappy. It’s a solid tool, just with the usual macOS security quirks to navigate on first launch.
All in all, a short but instructive session. It reminded me again that when a small utility refuses to launch, it’s rarely broken — it’s just Apple making sure you do things in the “proper” order. Once you understand the quarantine + permissions dance, it’s straightforward.
And now, Rest Editor is fully stable, fast, and ready for whatever API testing I need to do. A little frustrating at first, but that Terminal fix and permission tweak solved everything.
