Root composer.json requires yajra/laravel-oci8 6.1.2 -> satisfiable by yajra/laravel-oci8[v6.1.2].

yajra/laravel-oci8 v6.1.2 requires ext-oci8 >=2.0.0 -> it is missing from your system. Install or enable PHP's oci8 extension.

とあります。
パッケージからすると、ORACLEドライバー関係ですかね？
Oracle DB driver for Laravel 4|5|6|7|8 via OCI8
that uses OCI8 extension to communicate with Oracleとあるのでエラーメッセージにあるようにoci8をインストール/有効にする必要があるのでは。
Mac所持者ではないのでMAMPのデフォルト設定分かりませんが、少なくとも有効にはなっていないようです。
確実なのはPHPマニュアルを確認することと思いますが、エラーにも「PHP INIを確認してね（意訳）」の旨が書かれていますし、設定確認するところからですね。
