How to add iCloud calendar on macOS

  1. Install OneCalendar

    Download OneCalendar from the store and install it on your device.

  2. Select Accounts overview

    Select the OneCalendar menu on the top left, and select the option "Accounts".

  3. Select Add account

    Click on the "+" sign to add a new account.

  4. Select Account type

    You have 2 options for configuring iCloud calendar account.

    Option 1 "iCloud on device": this is the easiest option to configure (it doesn't need a password) but is doesn't allow you to assign colours to individual appointments, and it's not possible to invite people for appointments.

    Option 2 "iCloud": for this option you would need to setup an application specific password, it will be shown in the following steps.

  5. Option 2: Enter credentials

    • The username needs to be filled with your Apple Id.
    • The password needs to be filled with an application specific password. It has the format of XXXX-XXXX-XXXX-XXXX. Instructions to generate it will be shown below.
  6. Setup 2 factor authentication

    All third-pary applications (like OneCalendar) require an app-specific password for connection to iCloud due to Apple security measures. In order to do this it's first required to setup 2 factor authentication. You only need to set this up once if you haven't done so already. This can be done on you iPhone/iPad or on your Mac.

  7. Create app specific password

    • Sign in to your Apple ID account page.
    • In the "Sign-in and Security" section, click "App-Specific Passwords."
    • Click "Add"
    • Follow the steps on your screen.
    • After you generate your app-specific password, enter or paste it into the OneCalendar password field.
