Latitude E7470: need help installing Sonoma

Hi all,

 

Looking for some help here.. 

 

i am following these instructions to install Sanoma: 

 

So reading this i can skip the BIOS mod.. as long as i get these kexts.. so i have downloaded them.

  Quote

/!\ New Development: If you don't want to mod the BIOS as it might be difficult for some models, you could skip this step by adding 2 new kexts to /EFI/Clover/kexts/Other

Lilu.kext & Whatevergreen

Expand  

 

So then this install guide above then calls this other install guide..

https://osxlatitude.com/forums/topic/8506-dell-latitude-inspiron-precision-vostro-xps-clover-guide/#comment-54621

 

Which says use the bootpack ok.. so i downloaded that.. though that is the bootpack from El Capitan.. though ill assume it's the same Bootpack for Sanoma too? cause i cannot see any other..

Now the new 2nd tutorial talks about making the USB via a Mac.. which i do not have.. so are there instructions on how to proceed with a Windows or Linux machine? (Pref windows).

And then once you have the media all built you just need to use the updated "OC" file for Sanoma that is provided in the first tutorial?

 

Am i on the right track here? :)

 

Thank you.

Hello, you're not really on the right track, no...

 

For Sonoma (not Sanoma), go directly to the Sonoma guide, which is currently the last post of the entire thread; it's based on OpenCore v0.9.5 bootloader/tool hence the attached bootpack E7470_EFI_OC_0.9.5 (which you need to unzip before use).

Just skip the El Capitan-related post at the top of the thread and all the subsequent ones for other macOS versions that do not apply.

You obviously did not understand that each post was a guide in itself for a specific macOS version and that each guide contained its own Clover or OpenCore bootpack.

 

Then, as a newcomer, do consult our FAQ section where you'll find answers to some of those questions like creating a USB installer from Windows.

Excellent!

 

Managed to find a dmg download and used transmac to build the USB Installer!

 

Though still no love.. Boots off the USB without issue though Black Screen once you Select EFI. 

 

Here are my steps so far.

 

Download a dmg version of the macos.
run transmac or equiv to burn dmg file to usb.
   https://pureinfotech.com/create-macos-bootable-usb-windows/
    right click on your USB
    Format Disk for Mac
    Right click on your usb again
    Restore with Disk Image
    Select Dmg
    Wait for complete.

Use minitool partition wizard to map a drive letter of EFI parition of the usb

Copy the EFI folder suitable for your hardware to the partition.

"X:\EFI\"

Should contain Boot and OC folders.
X:\EFI\Boot
X:\EFI\OC


Boot from USB on target PC.
 

The boot works and i have an option to select EFI or Windows.

 

EFI just goes Black Screen.

Windows just BSOD Inaccessible Boot Device due to the BIOS change..

 

I'm going to try Ventura to see if its the EFI :)

 

Thanks for your help so far!

just tried the same instructions above using 

 

macOS Ventura 13.6 Public DMG and the EFI for Ventura (E7470_OC_0.8.5).

 

that one comes up with the boot picker though only has Windows listed...  No "EFI" like the other one..

 

So doesnt work either.. 

 

Not sure what i am doing wrong here..

Unfortunately no Change.  I did follow your BIOS settings from the link above.  Though just did it again as above now to be sure.

 

Is there particular BIOS version you need to be on?

 

Just to clarify you can build your USB Bootable Installer from a 'dmg' file and Transmac?

 

I have a friend of mine coming by this weekend with a Mac so will try with the pkg this weekend if i cant get it working otherwise..

 

Thanks very much guys.

Generally speaking and as stated in our published rules (which I invite you to read), you should not use any distro found on the Net. There's just no need given that all OS X and macOS versions are freely made available by Apple since Mavericks (Lion and Mountain Lion having been made available for free in June 2021). As such, the references to the distro you mentioned above have been removed.

Sure I understand. Though from what I have read you can't build a bootable USB installer from a PKG file on windows and that is the only official format.

 

So I have no option other that to use alternative sources. Though I'll refrain from naming them in future.

 

Hope my build on a Mac this weekend works.

looking at official opencore doco it seems that i am right.. you cannot make a full offline bootable usb in windows.  only in mac..

 

https://dortania.github.io/OpenCore-Install-Guide/installer-guide/

 

Quote:

Online vs Offline Installer

Offline installers have a complete copy of macOS, while online installers are only a recovery image (~500MB) which then download macOS from Apple servers once booted.

Offline

Can only be made in macOS

Windows/Linux do not have the APFS/HFS drivers needed to assemble a full installer

Online

Can be made in macOS/Linux/Windows

Requires a working internet connection via a macOS supported network adapter on the target machine

 

So that would be why my setup is not working as i was using the full install dmg file.  Will the EFI's provided work with an Offline version? I assume they will?

Will give it a shot..

 

so with offline installer and E7470_OC_0.9.5

After pressing space (apparently this gives you more options i just found out)

I get an option for EFI or EFI (dmg).

Choosing EFI ends up on blackscreen again.

Choosing EFI (dmg) gets the following error attached.

Going to try and merge Jake Lo's EFI with the latest version of opencore... 

 

06d4ede1-5c0d-4c14-bb09-17fc3adfdbeb.jpg

very minor difference in error.. though barely..

 

next debug version...

 

merged.jpg

 

--------------------

ok.. so i have rebuilt my usb with the latest offline version from apple using opencore python script:

python3 macrecovery.py -b Mac-4B682C642B45593E -m 00000000000000000 download

Have downloaded the 0.9.5 debug version and set it up so it aligns to Jake Lo's EFI.

Assume its prob some h/w change between models..  mine runs:

i5-6300u

SK Hynix SC308 128GB SATA Drive

Intel AC 8260 Wifi

Intel I219-LM Ethernet

8GB 2133Mhz (SK Hynix HMA41GS6)

 

So HDD does not match..  and only run half the ram than Jake's notes.. would that be enough for it to fail?

 

The debug is below would love some insight please :)

ok went down the google rabbit hole and people were referring to using OpenHfsPlus.efi over HfsPlus.efi.   (Jake's uses HfsPlus.efi).

So i added that to OC\Drivers and updated the plist and now i get a lot further..

even get to the prompt for "Windows" "OpenShell" "EFI" "EFI (dmg)" "Clear NVRAM" so it seems to have helped though still not getting to install phase after selecting "EFI (dmg)" from the options.

 

Debug again below from replacing HFSPlus.efi with OpenHFSPlus.efi
