Hello, I have followed the upgrade guide: https://laravel.com/docs/9.x/upgrade all the way to 'Symofny Mailer' but failing to do the following commands; composer install & composer update.

Composer Console Error Log:

From the error output you posted:

- werxe/laravel-collection-macros[v6.0.0, ..., 6.x-dev] require illuminate/support ^8.0 

You need to update this third-party dependency, which in the version you manually required in your composer.json does not work with Laravel 9 packages.

The upgrade guide suggests that:

Finally, examine any other third-party packages consumed by your application and verify you are using the proper version for Laravel 9 support.

I knew about it but since it doesn't support v9 yet and I am sure I don't use it, I decided to remove it... got another issue but thats with another package not being supported as well.

Thanks.

The cycle continues
