Hey,
So yesterday I spent a good chunk of the afternoon messing with Rack Attack (app) from OrchardKit on my M2 MacBook Air running macOS Ventura 13.5. I was trying to test some security scans on a local server setup — nothing fancy, just a couple of endpoints and a few routine checks — but it turned into one of those “oh, this should take 10 minutes” situations that quietly eats the better part of your afternoon.
The first red flag was right at launch. I double-clicked the app icon, and for a fleeting second, the Dock icon bounced — then nothing. No crash message, no dialogue, just gone. Classic Gatekeeper behavior. I had bypassed the initial “unidentified developer” warning via right-click → Open, but that alone didn’t help.
My first thought was corruption. Maybe the DMG or the ZIP bundle I downloaded from OrchardKit got munged in transit. I re-downloaded, verified the SHA256 checksum, and tried again. Same behavior. So the app itself was intact.
Next, I tried launching from Terminal. That’s when things got a little more informative. The app threw a permission error referencing ~/Documents/RackAttack and a couple of sandbox-related warnings. That’s when I realized this wasn’t a crash — macOS was silently blocking the app from accessing files it needed to start.
I jumped into System Settings → Privacy & Security → Files and Folders. Sure enough, Rack Attack wasn’t listed. I tried giving it Full Disk Access anyway, restarted, and still nothing. That’s when I remembered the quarantine flag. Even after bypassing Gatekeeper, unsigned or lightly signed apps keep a hidden attribute that can block access to user files and some system resources.
Running:
xattr -l /Applications/Rack\ Attack.app
confirmed it: com.apple.quarantine was still set. That explains the silent failure — the app was opening but immediately hitting a permissions wall before it could initialize anything.
I found this page useful while figuring out the nuances of macOS quarantine behavior and unsigned apps:

Following the advice there, I removed the quarantine attribute:
xattr -dr com.apple.quarantine /Applications/Rack\ Attack.app
After that, launching the app worked perfectly. First launch prompted correctly for access to Documents, Desktop, and external drives. I could run a test scan, and everything completed without silent failures.
A few micro-details I noticed: first launch after removing quarantine took a few extra seconds as the app initialized its local cache and security definitions. Once past that, the interface became snappy — CPU usage hovered around 4–5%, memory was steady, and the app didn’t bog down even during scans of large directories.
I also checked Apple’s notes on Gatekeeper and app notarization, which explain why apps sometimes fail silently even after bypassing the first warning:
https://support.apple.com/guide/mac-help/open-a-mac-app-from-an-unidentified-developer-mh40616/mac
And just to be thorough, I looked at the Mac App Store for any signed alternatives or updates:
Nothing official, so manually clearing quarantine remains necessary until OrchardKit releases a notarized build.
If I were installing Rack Attack again, my personal checklist would be:
- Copy the app to Applications.
- Remove quarantine with
xattr -dr com.apple.quarantine. - Launch once and approve access to Documents/Desktop/external drives.
- Verify scan operations and performance.
That’s it. After that, everything works smoothly.
It’s funny how nothing was really broken in the app itself. Interface, file handling, scans — all solid. The problem was entirely macOS silently blocking access behind the scenes. Once I understood that, it was more about nudging the system than fixing the software.
Anyway, after that little adventure, Rack Attack behaves exactly as expected. Quick scans, smooth interface, low CPU/memory footprint — classic OrchardKit quality. Just remember to clear quarantine flags on first launch, and you save yourself a lot of unnecessary frustration.
