So you’ve locked yourself out of macOS by making changes to your Clover EFI folder and you don’t have a backup to get back in. Fortunately there is a way to make changes to your EFI partition on Windows in case this happens to you.
Step 1. Mount EFI Partition on Windows
In order to be able to access the macOS EFI partition on Windows we first need to mount it. There are a couple ways to mount an EFI partition, in my opinion the simplest way is to give it a drive letter.
- Install MiniTool Partition Wizard Free Edition
- Open MiniTool Partition Wizard
- Right-Click the EFI partition and click Change Letter
- Select an unused drive letter (I picked Z:)
- Click Apply
- Apply pending Changes? : Yes
- Click OK
The EFI partition will not be mounted as you can see in Windows Exporer, but you wont have permission to access or edit it just yet.
Step 2. Access & Edit EFI partition on Windows
In order to open the EFI partition on Windows and be able to make changes to it’s contents we are going to use a third party program called Explorer++
- Download Explorer++
- Unzip explorer++.zip by right-clicking the zip file and selecting Extract All… and click Extract
- Open the now unzipped explorer++ folder
- Right-Click Explorer++ and select Run as administrator
- You should now see your EFI folder which you can open and make changes too through the Explorer++ program.
