EFI access, without the Terminal
ESP Mounter finds every EFI System Partition on your connected disks — internal, external, removable, and even inside disk images — and mounts them in Finder with one click, so you can edit boot configs or check bootloader files without typing a single diskutil command.
It automatically detects OpenCore and Clover installations, flags your active boot disk, and can clone an EFI folder from one disk to another with an automatic backup.
