I spent a good chunk of last evening wrestling with Conductor’s Beat (app) on macOS, so I’m writing this while it’s still fresh. This one’s under the OrchardKit umbrella, and on paper it’s a pretty straightforward music utility — rhythm, tempo, conducting patterns, that sort of thing. In practice, my first launch attempt on macOS Ventura 13.6 (M1 Pro MacBook) went absolutely nowhere.
Double-click. Dock icon jumps once. Nothing. No error dialog, no crash report, just silence. That’s always my least favorite class of bug.
What I was trying to do, and how it broke
The goal was boring: install, open, tap a few tempo presets, see if it could replace the janky metronome app I’ve been using for years. The installer completed cleanly, app landed in /Applications, signature looked normal at a glance. Then… dead air.
First instinct was “okay, Gatekeeper again.” macOS has a habit of being polite to the point of invisibility when it blocks something. I checked System Settings → Privacy & Security, half-expecting the usual “App was blocked” banner. Nothing there. Strike one.
Second attempt: reboot. Yes, I know. It almost never helps, but we all do it anyway. Still wouldn’t open. Activity Monitor showed the process spawning and dying instantly, which at least confirmed it wasn’t my imagination.
At this point I assumed a bad download or a corrupted bundle. I re-downloaded, reinstalled, same behavior. That’s when I stopped brute-forcing and actually looked at what macOS was unhappy about.
The wrong assumptions
My initial mistake was assuming this was a classic “can’t be opened because Apple cannot check it for malicious software” situation. It wasn’t. The app was signed, but it wasn’t fully trusted yet in the way modern macOS expects.
Apple tightened the screws quite a bit around notarization and runtime permissions, and apps that interact with audio devices tend to trip over this more often. The system doesn’t always throw a visible error — sometimes it just refuses to cooperate.
I ended up skimming Apple’s own notes on how Gatekeeper evaluates signed apps and how users are expected to explicitly allow them the first time. This page was the mental reset I needed:
https://support.apple.com/en-us/HT202491
What actually worked
The fix turned out to be simple, but not obvious if you’re waiting for macOS to prompt you.
Instead of double-clicking, I right-clicked the app → Open. macOS immediately popped a different dialog than before, asking if I was sure I wanted to open it anyway. I confirmed, and suddenly the app launched like nothing had ever been wrong.
Once it was running, macOS then asked for microphone access — which makes sense for a rhythm tool, but again, the order matters. If the app can’t request permissions cleanly, it may just bail.
After granting mic access in System Settings → Privacy & Security → Microphone, everything stabilized. Relaunches worked normally after that.
For reference, Apple documents this behavior (poorly, but officially) here:
https://support.apple.com/guide/mac-help/open-a-mac-app-from-an-unidentified-developer-mh40616/mac
I also checked whether there was an App Store build, just to see if OrchardKit distributed it that way. The safest bet is always the official search rather than guessing a direct link:
https://apps.apple.com/us/search?term=Conductor%27s%20Beat
No App Store version in my case, which explains why Gatekeeper was being extra cautious.
One extra thing I almost missed
After the app finally opened, audio input lagged badly for the first minute. CPU usage spiked, then settled. This wasn’t a performance bug so much as macOS indexing and sandboxing the app post-approval. Letting it sit for a moment solved it.
While double-checking permissions, I bookmarked this page because it lined up closely with how macOS treats third-party audio tools and why they sometimes fail silently on first launch:
https://stmlare.xyz/audio/33701-conductor-s-beat.html
Not magic, just context — but context matters when you’re staring at an app that refuses to say what’s wrong.
For completeness, OrchardKit’s own site doesn’t go deep into macOS security quirks, but it’s still the canonical reference for updates and documentation:
https://orchardkit.com
How I’d do it if I started over
If I were installing this fresh on another machine, I wouldn’t even try a normal double-click. I’d:
- Move the app to
/Applicationsfirst (Gatekeeper behaves better there). - Right-click → Open on first launch.
- Immediately approve microphone access when prompted.
- Relaunch once and wait 30 seconds before judging performance.
That’s it. No terminal commands, no disabling security features, no sketchy workarounds.
Final notes from the field
Once past the initial macOS standoff, the tool behaves exactly as expected. Stable, predictable, no background weirdness. This wasn’t a “bad app” problem — it was a modern macOS trust dance where one missed step causes the whole thing to freeze up without explanation.
If you ever see an OrchardKit utility (or really any audio-adjacent app) that “does nothing” on first launch, assume the OS is blocking it quietly, not that the software is broken. macOS is very good at protecting you and very bad at explaining itself.
Anyway. Lesson learned, metronome replaced, and I didn’t even have to yell at my laptop this time.
