Apple Models
Various information about Apple hardware (current database status).
Improving database
To add a new hardware board, please create a file in DataBase
directory, and then run ./update_generated.py. It should not
output anything and return zero code.
To install PyYAML on macOS use the following commands:
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
sudo -H python get-pip.py
sudo -H pip install pyyaml
Unpacking firmwares
To update the database you can either get the information from firmware images or from
running hardware. There currently are two places for firmware images: FirmwareUpdate.pkg
for generic models and BridgeOSUpdateCustomer.pkg for T2 models (the entire restore list
is available at mesu.apple.com)
To use them do as follows:
- Visit suitable update catalogue by filling the OS versions (e.g. this one for 11.0 beta).
- Download most recent
FirmwareUpdate.pkgandBridgeOSUpdateCustomer.pkg. - Extract
scapfiles fromFirmwareUpdate.pkgfiles and use them as is. - Extract
/usr/standalone/firmware/bridgeOSCustomer.bundle/Contents/Resources/UpdateBundle.zipfile fromBridgeOSUpdateCustomer.pkgand unpack it. - After unpacking
UpdateBundle.zipgo toboot/Firmware/MacEFIdirectory and unpack im4p files. You can use img4, img4tool, or our dedicated MacEfiUnpack. For example,for i in *.im4p ; do ./MacEfiUnpack.py "$i" ; done
