The Mac app comes from this website, and nowhere else.
The first time you open it
The download is a disk image. Open it, then drag Mass Employment Companion onto the Applications folder beside it. Eject the disk image when the copy is done.
The first time you open the app, macOS may ask you to confirm that you want to open an app you downloaded. Choose Open.
When you include your Photos library, macOS asks for Photos access. When you include a folder, you choose it in the Mac's own file window, and the app reads only what you choose.
What stays private
The Mac app reads the folders and Photos you choose and keeps its encrypted index on this Mac, separate from the browser library. Scanning does not send your files or list them for sale. If you choose to list them, we receive the listing information you approve. Approved deliveries are encrypted before leaving your device and may pass through our temporary relay. We cannot decrypt them. Each license and delivery needs your approval.
For the technical reader
The app shows its screens in the WebKit view that is part of macOS. macOS may check the app's signature and report crashes under your system settings. A local inventory does not mean that every part of macOS is offline.
Needs macOS 13 or later.
Fix a problem safely
macOS says the app cannot be opened
Do not change your security or privacy settings to get around this. Delete the disk image you downloaded, download the Mac app again from the Download page and check that its checksum matches the one shown beside the download. Then try again. If it still does not open, contact support with the exact message.
The encrypted local library could not be opened
Quit other copies of the app. Open it again under the same macOS user account, because that account protects the saved index. Do not delete the library, change its permissions or clear the index to work around this error. If it continues, contact support with the app version and the error text, without private file details.
Photos access is off
Open System Settings, then Privacy and Security, then Photos. Turn on access for Mass Employment Companion. Then scan again. The app reads only the photos you include.
Some files were skipped
Read the stated reason: files the app cannot read, links and special entries may be skipped, and a completed scan does not mean every file was readable. Fix the source problem, then scan again.
Install an update without losing my library
The Mac app does not update itself. A newer Mac app is a new file on the Download page. Finish or stop any scan and quit the app, then open the new file and drag the app into Applications again. Choose Replace when macOS asks. Your encrypted index stays on this Mac. Uninstalling or deleting app data is not an update step. Keep your original files and, when your app offers encrypted backup, save a backup and keep its passphrase separately.
When do I see a price or a buyer request?
A buyer request appears when a buyer asks for files like yours, and every request shows its price before you decide. The app shows a reference value for your files, which is a formula, not an offer or buyer demand. You can link your account to the app, and the context you add helps organize a review but does not verify rights.
For support, share the version, error text and steps that caused the issue. Do not email source files, your encrypted library, backup passphrases, recovery keys or screenshots containing private paths. Review any diagnostic file before sending it.
