# Installation on MacOS

## Via Homebrew

This is the easiest method.

* add the Homebrew tap with `brew tap on4kjm/tap`.
* install the application with `brew install flecli`.

## Manual installation

At this stage, the MacOS FLEcli binary is not signed. It will fail to load on recent MacOS version.

This procedure will guide you for adding FLEcli to the exception list.

When the executable has been unpacked in a directory and that you try to execute it in the console (`./FLEcli`), you will get the following error:

![cannot be opened because developer cannot be verified](pictures/Error_1.png?raw=true)

Make sure that you choose "cancel" to close the dialog.
Having triggered that error will allow you to enable the exception.

Enter the "system preference" and choose the "Security Settings".

![System preferences, select security and privacy](pictures/System_preference.png?raw=true)

On the "general" tab, you will see the problem that just occurred ( _"FLEcli" was blocked from use because it is not from an identified developer_ ). Click on the "Allow Anyway" button.

![general page, allow apps downloaded from, Allow Anyway for FLEcli](pictures/security_setting.png?raw=true)

When trying again to execute the application, the error message will be slightly different:

![macOS cannot verify the developer of FLEcli.  Are you sure you want to open it?  Select open](pictures/Error_2.png?raw=true)

But this time, choose "open". The exception is now registered.
