A lot of the laptops made by Huawei and Xiaomi are MacBook-like in design at least. Framework is much more repairable though as are business laptops from HP or Dell. Dell in particular has made some quite long battery life laptops in the past like the Latitude 7410 and 7400, though those aren’t particularly new they are at least cheap when bought second hand.
In terms of OS you got to go with some Linux flavor as they offer various DEs some of which are mac like. Obviously macOS and Linux terminals are somewhat similar anyway. PopOS is a great option.
