I should check if "Seethrough" is an existing macOS patch. A quick search tells me that Seethrough is related to enabling visual effects like see-through windows. Lilu is a kext used by patchers like Seethrough. The user might be using OpenCore or Clover for boot installation. The version SS 11 is macOS Sierra 11, so the user is on an older macOS version.
Potential misunderstandings: The user might be trying to run an MP4 file as an installer, which isn't correct. The installation process for Lilu and Seethrough typically involves using a patcher like oLiu’s Seethrough Patcher. The user needs to know the correct steps, including using the right tools and possibly a terminal command. Also, macOS Sierra is outdated, and support might be limited now. They might not have access to certain tools or repositories. ss lilu ss 11 seethrough mp4 install
I should outline the installation steps step-by-step, using the correct tools for macOS Sierra. Emphasize that it's important to back up data before modifying system kexts. Also, clarify that Seethrough is an older patcher and may not work properly on newer macOS versions, but since they're using Sierra, it should be compatible. Mention the use of a terminal command or a DMG installer. Clarify that "seethrough.mp4" is likely a miscommunication and the actual installer is a DMG orPKG file.
