Hey !
I have news for mac installation 
1.Downloading WineBottler
2. Open the DMG, and copy Wine and WineBottler to your applications folder.
3. Download the KeePass setup file.
4. Open WineBottler
5. Click advanced in the top bar
6. Make sure it says new prefix
7. Select the box that says "This is the installer, execute it"
8. Locate the KeePassSetup.exe file from within WineBottler
9. Scroll down a little and make sure it includes the open source .Net framework mono
10. Make it include wine.app
11. In winetricks, find and check dotnet45 (MS .NET 4.0)
12. In winetricks, find and check forcemono (Force using Mono …)
13. Give the app an identifier
14. Build your app!
15. It will take a long while (You may have to download .NET 3.0 and restart the build process)
16. Execute it, and it will copy the prefix.
17. If it closes, open it again
17. If you need plugins, copy them to ~/Library/Applcation Support/ then find the identifier
18. Done
I found this guide here https://superuser.com/questions/995881/permissions-to-browse-outside-of-home-directory-when-using-mono-to-run-exe-on-ma
And it’s working fine with kee or other plugins so I guess it’s good !
Granted it’s not as simple as pushing a button but it’s still easy for users don’t worry.
