Download & set up on your Mac
Everything you are licensed for sits in one folder. Read the five steps, download the app, then send me your machine ID for a licence code.
Setting up
Five steps, once per MacPick the right file for your Mac
If it says Chip: Apple M1 / M2 / M3 / M4, take the Apple Silicon file. If it says Processor: Intel, take the Intel one. The two are not interchangeable — the wrong one simply will not open.
CardVault-1.1.0-macOS-arm64.dmg · CardVault-1.1.0-macOS-x86_64.dmg
Always take the newest version listed in What’s new.
Install it
Double-click the .dmg you downloaded. A window opens with the app on one side and an Applications folder on the other — drag the app onto Applications. That is the install.
Then eject the disk image (click the ⏏ beside it in Finder’s sidebar) and delete the .dmg if you like. The app now lives in Applications and opens from there or from Launchpad.
Open it the first time
The first launch is the one awkward moment. macOS will say the app “cannot be opened because Apple cannot check it for malicious software”. Nothing is wrong with it — these are custom-built tools made for you, and they do not carry a paid Apple certificate.
You only do this once per app. Which of these two you see depends on your macOS version:
Most Macs
Right-click (or Control-click) the app in Applications → Open → Open again in the dialog.
macOS 15 Sequoia and later
Try to open it once, then go to System Settings → Privacy & Security, scroll down to the message about the app and click Open Anyway.
Send me your machine ID
The app opens in your browser after a second or two. That tab is the app; it runs quietly on your own Mac, with nothing on screen behind it.
The first screen shows YOUR MACHINE ID. Click Copy and send that code to me so I can issue your licence.
Activate, then set your master password
I will send back a licence code. Paste it in and click Activate — the tool unlocks straight away.
The licence is generated for that Mac only. If you move to another machine the same file will not activate — message me and I will issue a fresh licence. To check your licence later, or paste a renewal code, use the licence chip in the app header.
Each tool that holds your data then asks you to set a master password on first unlock. It encrypts everything on your Mac, and then you are free to start adding your details.
