 [this](https://github.com/grpc/grpc-node/issues/1497) issue) the Apple ARM64 build must be done in 2 stages:
 
 1. Build management interface proto files on a non-ARM64 platform
-2. Use the built proto files during the main build by setting the `MI_PROTO_BUILD_DIR` environment variable
-   to the path the proto files
+2. Use the built proto files during the main build by setting the `MANAGEMENT_INTERFACE_PROTO_BUILD_DIR`
+   environment variable to the path the proto files
 
 To build the management interface proto files there is a script (execute it on a non-ARM64 platform):
 
 ```bash
 cd gui/scripts
-./build_mi_proto.sh
+npm ci
+./build-proto.sh
 ```
 
-After that transfer the resulting build directory to your Apple ARM64 platform, and set the value of
-`MI_PROTO_BUILD_DIR` to the transfer destination while running the main build.
+After that copy the files from `gui/src/main/management_interface/` and `gui/build/src/main/management_interface/`
+directories into a single directory on your Apple Silicon Mac, and set the value of
+`MANAGEMENT_INTERFACE_PROTO_BUILD_DIR` to that directory while running the main build.
 
-Another prerequisite is `protobuf`, which can be installed by running:
+On your Apple Silicon Mac install `protobuf` by running:
 
 ```bash
 brew install protobuf
 ```
 
-When all is done run the main build:
+When all is done run the main build. Assuming that you copied the proto files into `/tmp/management_interface_proto`
+directory, the build command will look as follows:
 
 ```bash
-MI_PROTO_BUILD_DIR=/Users/doe/mullvadvpn-app/gui/scripts/mi_proto ./build.sh --dev-build
+MANAGEMENT_INTERFACE_PROTO_BUILD_DIR=/tmp/management_interface_proto ./build.sh --dev-build
 ```
