Sometimes it might be useful to reload a kernel extension in OSX without rebooting your Mac. This can be done in a terminal window with the following commands:
sudo kextunload /System/Library/Extensions/NameOfExtension.kext sudo kextload /System/Library/Extensions/NameOfExtension.kext
Replace NameOfExtension.kext with the name of the extension you want to reload.
You may first want to check if the kernel extension being unloaded has dependencies, in which case unload will fail. Use kextstat and look at the “linked against” column.
Third-party kexts usually don’t have dependencies but system kexts are tightly depend on one another.
Take at least a glance at the before monkeying around with kexts.
