Project description:
"I’m looking for an experienced macOS developer to fix an application that currently cannot be opened on macOS.

Important context (please read carefully):
This is NOT the official app.
It is a modified copy of an existing macOS app, adapted so that UI elements can be edited directly. The app works conceptually, but macOS refuses to launch it due to bundle / framework / code signing issues.

The goal is not App Store distribution — I just need the app to open and run locally on my MacBook without macOS blocking it.

Current Problem

When opening the app on macOS, I get errors such as:

“The application cannot be opened”

“A sealed resource is missing or invalid”

Launch failed (code 111)

Framework issues (Electron / [login to view URL])

We already identified that:

The app bundle structure is incorrect

macOS code signing is broken

The app was not packaged properly for macOS

What Needs to Be Done

The freelancer will need to:

Fix or rebuild the macOS .app bundle structure

Correct Electron/macOS framework issues (ex: [login to view URL])

Properly repackage the app so macOS recognizes it as valid

Re-sign the app (ad-hoc signing is fine)

Ensure the app launches successfully on macOS (Apple Silicon)

No App Store submission required.
No notarization required.
Just needs to run locally without security errors.

Tech Stack (Likely)

macOS

Electron

Node.js

macOS code signing

App bundling (.app / .dmg)

Apple Silicon compatibility (M1/M2/M3)

Deliverables

A working .app or .dmg file

App opens normally on macOS

No Gatekeeper / “app damaged” / “cannot be opened” errors

Who This Is For

macOS / Electron developers
Developers familiar with macOS app signing & bundle structure
NOT for beginners
NOT for mobile-only devs

If you’ve already fixed “app won’t open on macOS” issues before, this is a quick job.

To Apply

Please include:

Your experience with macOS apps or Electron

Similar issues you’ve fixed before

Your estimated time to fix this

If you want, I can also:

Rewrite this to be shorter / more aggressive

Add a budget range

Optimize it to attract senior devs only

Or tailor it specifically to Electron experts

Just tell me" (client-provided description)
