摘要： A driver management method and apparatus for a Mac system are provided. The method includes: receiving a driver file uninstallation instruction of a current device; determining whether the driver file is installed only in the current device among devices without uninstalling the driver files according to the driver file uninstallation instruction; if yes, uninstalling the driver file; if no, reserving the driver file. The method and apparatus solves a compatibility problem of multiple devices sharing a driver file very well. When the current device needs to uninstall the driver file, it is ensured that other devices that need to load the driver file can normally load and use the driver file, thereby avoiding the occurrence of the condition of the drive conflict resulted from the erroneous deletion of the driver file.
