Just in case, I will like to share my experience.
I updated from .3 to .4 without any issue."flawlessly". But I been doing or using the same routine for years. I always update. But then a few days later, I always reinstall the macOS and make a new backup. I like to keep everything clean and organized
So, after I attempted to clean install .4, i was having nothing but trouble. But updated from version .3 to version .4 without any problem. Weird!
Then I decided to update Clover to the latest version, version 4910. After that, the installer loaded completely, and I made the new installation.
So, while the previous version of clover was booting .4 just fine, it didn't want to or refuses to load the installer. Only after I updated Clover to the latest version, then .4 installer loaded and installed.
I hope this help someone who might be having the same issue and don't know what is the problem. I think that's why it is always good or recommended to update Clover after Apple releases a new major update.
Sorry for my broken down English.
Regards.
