This is a very simple droplet application to install kexts and rebuild the kernel cache.
- Drag one or several Kexts on the application (not a folder),
- Select the destination (LE or SLE),
- Choose if you want to rebuild the kernel cache or not,
- If so, choose if you want to restart the computer or not.
If the file already exists at destination, you will have the choice to skip or replace it (in that case, the original will be moved on a Backup folder on the Desktop).
