Why it depends
Microbial or vegetable rennet, used in most modern cheese, raises no animal question at all. Animal rennet is a genuine difference between the schools: the Hanafi school, and one well-known Hanbali report, accept it even from animals not slaughtered Islamically, while the Shafi'i and Maliki schools require halal slaughter. A scan applies your own school.
