Clover 4509 issues - can't see my High Sierra drive to boot from anymore

Hi all,

I installed Clover 4509 and as I've now discovered there are users with my issue. Reverting to 4458 seems to be the trick but here's my question.

Can I copy files from my Windows 10 OS to the EFI folder on the OSX drive?

I have downloaded and extracted the contents from the 4458 PKG file to my Windows machine. I can access and write to the EFI partition on my OSX drive. I can also write to the High Sierra partition as I have Paragon HFS for Windows. Just not sure what file(s) to copy over.

Thanks in advance.
