I have a problem below:
I used XAMPP and magento2 with event: sales_order_shipment_save_before I can dump, die.... and it go to this event when saving shipment.
But when I coppy same source and database to MAMP. I have dump, die..... but it doesnt effect. I guess It never go to this event on MAMP. Althought I was setup, update, deploy, cache, compile but it still not work on MAMP(or I lose some step).
Anyone meet this problem? Thank you.
