Thank you for the opinion. Scailer has unique design that improves user’s experience in email. We decided that Scailer should look same on both platforms.

Regarding performance of the application on the old Mac, if you try it on and give us feedback, it will be really appreciated. We tested it on really slow PC and it works normally.

Regarding the keychain. Keychain is aimed to store an encrypted data. MacOS prevents other applications from accessing keychain data of other applications. Scailer uses own isolated keychain to store encryption keys to protects user’s data from 3d-party access. Scailer stores database encryption key in user’s keychain and license encryption key in system keychain. When Scailer adds an encryption certificate in system keychain, MacOS asks user to allow Scailer to do that. It will not allow Scailer to read keychain data of other applications, system or user. MacOS only allows the particular application to read keychain data created by that particular application. Using system keychain allows all users of the same Mac to use the same Scailer license.
