Hi
I have a macbook Air that i used two years ago to get Sierra through MAS. Then following the guides i was able to create Sierra Hackingtosh. But now, due to incompatibility issues with somes apps i need for work, i have to downgrade to El Capitan, but for now MAS offer Catalina as the only upgrade available. So i downloaded El Capitan from apple support link (they offer old OSX via official links). a huge file (5.8GB) named installMacOs.dmg that i ran in the macbook air that puts a 6.2GB install osx el capitan in applications folder. Unibeast (6.2) yields "selected mac osx installer is incomplete". If a use create install media method and adding the clover bundled with unibeast to usb installer, with this usb the installation of El capitan stops while remaining 1 minute to complete telling the installer is bad. I compared with original install sierra installer and found that el capitan installer lacks a MAS folder inside. Tried also to atach user of MB air to my apple id (maybe this way signs the web downloaded installer) and doesnt let me. Tried also the changing dates solution.
Help!
Thanks
(sorry my bad english)
