Mojave Doubt - Bootcamp - Restart in Macos from Windows

Hello team,


I have a MBP MID 2012 (i7, 1tb SSD, 16gb RAM) with 2 partitions:

  • The latest Windows 10 version + Paragon HFS for Windows.
  • The latest Macos High Sierra version with HFS+ format + Paragon HFS and NTFS for Mac.


Now, I am able to do the following:

Have read and write access to both drives, from Windows and Macos:

I am able to Restart in Macos from the Bootcamp Control Panel:

If I do a clean Mojave installation in the current HFS+ High Sierra Partition, I have read that this time we are no longer able to avoid the APFS conversion anymore (Can you update to macOS 10.14 (Mojave) without converting to APFS? - Ask Different) so I would like to know whether despite I proceed with the clean install of Mojave (plus APFS conversion) would lose the features mentioned before.


Thanks in advance,


Best regards

Hi,


After a lot of hours of research, I have manage to make the BootCamp tool able to restart into an APFS macos (Mojave or High Sierra).


The feature I mean is the following:


User uploaded file


To do so, we have to take the following instructions:


1. Open Terminal and Launch diskutil list to see the partitions: (this is my case):

User uploaded file


2. Create the new volume with HFS+ format labeled "APFS Bridge":

a. It shrinks the APFS container (disk1) by 200 MB and creates the new 200 MB "Mac OS Extended (Journaled)" volume labeled "APFS Bridge".


sudo diskutil ap resizeContainer disk1 177000M JHFS+ "APFS Bridge" 200M


3. Reboot macos.

4. Download the rEFInd Boot Manager from its web site (https://sourceforge.net/projects/refind/).

5. Install it into the new "APFS Bridge" volume, by entering the following commands:

a. Supposing that the program is maintained in the Downloads folder.

b. Supposing that the mentioned disk is disk0s3.


cd ~/Downloads/refind-bin-0.11.4


./refind-install --ownhfs /dev/disk0s3


6. Go to Volumes/APFS Bridge/System/Library/CoreServices.

7. Open the refind.conf with the Textedit.app, then, add the following lines into the very end of the file. (This will maintain the mac BIOS instead the new rEFInd program):


#

# Added to make rEFInd silent.

#

menuentry "APFS Bridge" {

icon \System\Library\CoreServices\icons\os_mac.png

volume "Macintosh"

loader \System\Library\CoreServices\boot.efi

ostype MacOS

graphics on

}

timeout -1

hideui all

scanfor manual


8. To avoid that the new Volume gets mounted, we have to launch the following lines in the Terminal:

a. Supposing that the Volume is named APFS Bridge. (The \040 is the octal representation of the space character and has to be maintained):


sudo bash

echo >>/etc/fstab

echo "LABEL=APFS\040Bridge none hfs rw,noauto" >>/etc/fstab

exit

And finally it works!!! and the Paragon is not needed to accomplish this.


Hope it helps.


Best regards

What I actually don't want to lose is the ability of Restart in Macos from the Bootcamp Control Panel. I fear this because this BootCamp tool, as far as I know, is only compatible with HFS not with APFS. Is this right? Will I lose this feature when I install the Mojave, obligating to change the macos partition from HFS to APFS?

Hello Loner T,


Thanks for your answer, but I would like to see a more specific evidence of the loss of the feature I am talking about, i.e. to make BootCamp software compatible with the reboot into macos.


Regarding the Paragon APFS software is not exactly what I want, as I stated before, because I just want native Bootcamp feature work, despite now I have the HFS Paragon one installed, but I doesn't have the feature of reboot in macos as the Bootcamp software has.


Does anybody have any specific experience with this?


Thanks in advance,


Best regards

Thankyou so much. I googled so many times looking for this solution. I recently setup my 2009 Mac Pro with Mac OS Mojave and decided to dual boot with Windows again, but this time I installed it through EFI. As legacy always seemed to drastically slow down the HDD loading times.


So many people are looking for this solution. I only stumbled across your thread.


Because my Mac Pro is designed to boot bootcamp legacy it doesn't work when I try and switch from Mac OS. I have a unique issue not being able to use option boot screen either. I can boot to it either resetting my pram and putting Windows in the 1st HDD bay.


I just wanted to ask if you think I could use your solution using refind to boot Windows from a bridge partition also. Since it's EFI and boots it like a Mac partition, say in select Startup disk and select a HFS bridge partition and point that back to Windows to work the same way?


Do you think it's possible?

Hello Daletanium,


First of all, it is not my solution, I brought it from here: windows 10 - Windows10 - Bootcamp Could not locate the macOS boot volume - mac partition unknown - Super User

But I rewrote it to make it more understandable.


Regarding your question, I really don't understand your problem... But I have to say that pure technically speaking, I am not very sure what it is doing behind, but somehow, the file /Volumes/APFS Bridge/System/Library/CoreServices/refind.conf, is pointing the APFS Bridge to the main Macintosh drive, for the Bootcamp Windows tool, when click on Restart in OSX option, point via rEFInd to the APFS Bridge.

But I that is all... And I don't have any idea of how to help you...

Sorry mate.

Is this related to a unsupported GPU being used?

Is your macOS partition an APFS Container with relevant volumes? Post the output of
