Master Password App Won't Work on My 2019 MacBook Air

I have had the Master Password App on my iPhone since 2017. I have all my important sites in it. I'm new to Apple computers though and I'm having trouble getting this app to work on my new 2019 MacBook Air. First I got your app from the App Store, it goes into Applications and I can easily see it by clicking Launch Pad. I click it and it opens, prompts me to create a user, then it will produce my familiar password to a site. So far so good. After I navigate to the site to paste in my password and come back to the Master Password App, it won't open. When I click the icon to open, the window containing Launch Pad apps sort of dims, then when I release the click it goes back to normal. The MP App icon is still there but it doesn't open.

I then downloaded it from your site and it lands in downloaded files folder, I double click it to hopefully install it and but it doesn't do anything I can see. Later when I try to delete the file, it says it's running and can't be closed. I can't find it anywhere and have to shut down the laptop to be able to delete the apparently unusable downloaded file.

Any suggestions?

Here are my system specs:
Mac OS Catalina
Version: 10.15.1
MacBook Air Retina 13 inch 2019
Processor: 1.6 GHz Dual Core Intel Core i5
Memory: 8 GB 2133 MHz LPDR3
Graphics: Intel UHD graphics 617 1536 MB

    Hi O.W.,

    Thanks for reaching out with your problem and for being with us for so long!

    There are definitely a few unintuitive things about Mac apps that are not immediately obvious - let me help clarify a few things! The downloaded Master Password app probably lives in your Downloads folder. On macOS, we don't really "install" things like we do elsewhere - applications are self-contained "folders" that look and act like nothing more than a single file. You can keep the app in your Download folder just fine, but most people move downloaded apps into the Applications folder by dragging it there in the Finder. If you've already installed Master Password through the App Store too, dragging it to Applications will prompt you to overwrite the existing Master Password version that's there.

    After starting up Master Password for the first time, it will live in the background. Starting it up again from the icon won't do anything since it's already running in the background. You can find the background app by clicking the menu icon for it. The "menu" is the single bar at the top of the screen that is shared by all applications, and the "menu icons" are on the right side of it. You'll see icons for the click, battery, Siri, etc. there, along with an icon for Master Password when it's running, it looks something like this: •••|

    Clicking the menu item will show you the options for interacting with the app, but you can also bring it up quickly using the global shortcut keys: Command + Control + p. This will be the quickest way to get into the app.

    Let me know if there's anything else I can help explain!

    Maarten (Staff),

    Thank you very much for the explanation of the interface on Apple regarding your MP App. It works just as you described. It is a relief to get that explanation!!

    One other mystery, when the App is open I see a gear icon in the upper right hand corner of th MP App screen. Even if signed in, if I click that gear icon the program swishes off the screen. I thought it was for settings or something but now I am not sure what it is. What about the gear icon??

    Thanks for your help!

    The gear icon is supposed to do the same thing as clicking the menu icon: open the menu drop-down under the icon. If it doesn't do that: no worries - clicking the menu icon directly has the exact same effect. Perhaps the swishing is related to you using multiple screens/desktops, but I can't be certain.

    Let me know if there's anything else!
