Realitiblu Posted August 7, 2018 Share Posted August 7, 2018 So, I don't understand what's causing this. I had an issue where I needed to change my EFI files on High Sierra due to a booting issue. It was suggested at Hackintosher that I do a fresh install, so I decided to go for Mojave & had some issues with the drive not being seen by boot loader after the installation.Today, I completely remade the flash drive and it booted first try! I'm typing from my system now - but Clover won't mount EFIs still & I'm at a loss. I'm so close to done but I don't know how to force the EFI partitions to show up.

Gigamaxx Posted August 9, 2018 Share Posted August 9, 2018 This issue has been coming up in Mojave with Clover Configurator app. EFIMounter works and if you update Clover Configurator it seems to be working now.

aslebenoni Posted December 10, 2018 Share Posted December 10, 2018 I am running Clover Configurator 5.3.2.0 and can not mount my EFI folder. I now have to boot of a USB because I can not fix my main EFI folder so it can boot. With Clover Configurator I can not mount anything :-( Here is my disklist: ➜ /Volumes diskutil list /dev/disk0 (internal): #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme 500.1 GB disk0 1: EFI EFI 209.7 MB disk0s1 2: Apple_APFS Container disk1 499.9 GB disk0s2 /dev/disk1 (synthesized): #: TYPE NAME SIZE IDENTIFIER 0: APFS Container Scheme - +499.9 GB disk1 Physical Store disk0s2 1: APFS Volume Macintosh HD 269.3 GB disk1s1 2: APFS Volume Preboot 65.1 MB disk1s2 3: APFS Volume Recovery 1.0 GB disk1s3 4: APFS Volume VM 2.1 GB disk1s4 /dev/disk2 (internal, physical): #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *4.0 TB disk2 1: EFI EFI 209.7 MB disk2s1 2: Apple_HFS Data 4.0 TB disk2s2 /dev/disk3 (external, physical): #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *15.6 GB disk3 1: EFI EFI 209.7 MB disk3s1 2: Apple_HFS Install macOS Mojave 15.3 GB disk3s2 ➜ /Volumes sudo diskutil mountDisk disk0s1 One or more volume(s) failed to mount I also tried EFI Mounter V3 and EFI Mounter Pro. Am I mounting the correct EFI volume? Link to comment https://www.insanelymac.com/forum/topic/335113-efi-not-mounting/#findComment-2653053 Share on other sites More sharing options...
osx151212 Posted December 12, 2018 Share Posted December 12, 2018 (edited) Hi, if you are not booted in safe mode (-x) then you should be able to mount EFI partition. I assume that you have only one HDD with EFI partition then try the following commandsudo diskutil mount EFI to unmount EFI partition you can issue the following commandsudo diskutil umount EFI NOTE: sudo temporary switches into 'administrator' account which is required to mound a partition. If nothing else works you always can use live Linux and manually mount required partition and edit configuration file manually (works every time). A good live Linux distributions is Knoppix -- just get 8GB flash drive and you ready to go. osx151212 Edited December 12, 2018 by osx151212 Link to comment https://www.insanelymac.com/forum/topic/335113-efi-not-mounting/#findComment-2653374 Share on other sites More sharing options...
osx151212 Posted December 12, 2018 Share Posted December 12, 2018 (edited) Hi, in your output of 'diskutil list' I see 3 EFI partitions (disk0s1, disk2s1, disk3s1). disk3s1 is external disk, probably USB drive which you can disconnect before mounting EFI partition (if you do not boot from USB drive) You require to know what EFI partition you boot from before mounting it (otherwise your changes will have no effect). When you installed Clover boot loader you was offered to select a OSX disk (with a name) to install boot loader -- if you remember name then you will see in the 'diskutil list' output a partition with same name, it is a clue. Once you know what partition you want to mount then issue following commands (substitute _ on proper disk number). sudo mkdir /Volumes/EFI mount -t msdos /dev/disk_s1 /Volumes/EFI to unmount /Volumes/EFI issue the following command sudo diskutil umount EFI NOTE: to have several EFI partitions on work system is not good idea -- it will create confusion, Clover can find kexts/configuration files on a partition which you do not take into account at boot time. Very un-recommended approach. Better to have one EFI partition on HDD and one on USB drive for 'recovery' purpose (connect USB drive before booting for recovery purpose and boot from it, otherwise connect USB drive only after the system booted up -- in this case you know for sure that HDD EFI partition was used to boot the system). osx151212 Edited December 12, 2018 by osx151212 Link to comment https://www.insanelymac.com/forum/topic/335113-efi-not-mounting/#findComment-2653375 Share on other sites More sharing options...

willibald Posted August 20, 2019 Share Posted August 20, 2019 I am running Yosemite on one drive and managed to install a bootable High Sierra USB. It just does not seem to install to the target drive. This one is now not recognized by disk utilities and does not appear as bootable drive. The application is formatted to AFPS. Maybe the target drive is not reactive anymore because it was not formatted the right way?
