Mac on Windows using VirtualBox ?

[GlennSprigg]

I've never touched a Mac in my life!, and only want to look around & play with it, for general education. 
Now I've seen NUMEROUS Sites explaining all the steps, including many YouTube videos, but have not had success...
My Windows laptop has 2 large drives, and 24gb RAM.  I've had no problems setting up VirtualBox, including the latest AddOns Module.

As per numerous instructions/sites, I've initially set up the "MacOS High Sierra 10.13" Virtual Device, using all the specified settings etc,
with the exception of offering even 'more' RAM and HardDrive space than the basic amounts required, as I have the availability. All that
seems fine!, and after specifying the (various versions downloaded!) .ISO file that Mac OS, and clicking on 'Start', it seems to be booting
just fine from the .iso and starts streaming command lines on the screen, eventually 'Starting' an 'Apple' GUI Window asking for the Language.
(I'm assuming that so far, all this is just loaded into a Virtual RAM Drive!)
Then, still within the Apple GUI, it comes up with a Menu, to Install, & also to select Disk Utilities which I was told to select first, at that stage,
and to Format the 'Drive' I had allocated. (Assuming it is also making it compatible for a Mac!!).  All done OK, & back to the menu, to 'Install' 
After initiating the final 'Install', that's when the shit hits the fan!!      It pops up a message box, saying...
"This copy of the install MacOS High Sierra application is damaged and can't be used to install MacOS"

Now, after searching on Google about this precise problem, numerous Sites stated that this is actually a LIE, (about being 'damaged'), and it is
actually due to Apple trying to STOP people from trying to install older versions, date-wise, and they explained various work-arounds! (Yay!!)...
Now I forgot to mention earlier, that after initially setting up the 'Virtual Device', you have to completely close down VirtualBox, and from a CMD
shell with Administrator rights, enter/copy & execute the following lines... (I found/tried a few versions)...

cd "C:\Program Files\Oracle\VirtualBox\"
VBoxManage.exe modifyvm "macOS 10.13 High Sierra" --cpuidset 00000001 000106e5 00100800 0098e3fd bfebfbff
VBoxManage setextradata "macOS 10.13 High Sierra" "VBoxInternal/Devices/efi/0/Config/DmiSystemProduct" "iMac11,3"
VBoxManage setextradata "macOS 10.13 High Sierra" "VBoxInternal/Devices/efi/0/Config/DmiSystemVersion" "1.0"
VBoxManage setextradata "macOS 10.13 High Sierra" "VBoxInternal/Devices/efi/0/Config/DmiBoardProduct" "Iloveapple"
VBoxManage setextradata "macOS 10.13 High Sierra" "VBoxInternal/Devices/smc/0/Config/DeviceKey" "ourhardworkbythesewordsguardedpleasedontsteal(c)AppleComputerInc"
VBoxManage setextradata "macOS 10.13 High Sierra" "VBoxInternal/Devices/smc/0/Config/GetKeyFromRealSMC" 1

I had DONE this, as requested, which sets additional parameters to the Virtual set-up, that can't be done in the VirtualBox GUI.
Evidently, it helps 'fool' the MacOS that it is going to a 'real' Mac computer!!  This was all done, before trying the final 'Install' 
Now their main Work-Around' consisted of extracting the contents of the initial MacOS .ISO, and finding a file called 'installinfo.plist'
which was in the...  \Install macOS High Sierra.app\Contents\SharedSupport\ folder.  Using (trying) VARIOUS ISO tools, I found and
DELETED this file, (that was their common solution that is supposed to work!), and then re-created a new .ISO !  (But alas !!!)...
It NOW won't boot at all, it seems, because it's no longer a BOOTABLE .ISO !!!  (Aaarrgghh...)   

I've looked for/tried many utilities, but I seem to have no way to make a 'Bootable' .iso to install this MacOS with, without a 'Mac' !!??
Any help would be much appreciated!!

I am using "Ubuntu Focal Fossa" together with "VirtualBox" and "VMware Workstation".



As far as I am concerned "VirtualBox" is the best proggy for "virtual Linux and virtual Windows machines" - especially for "Windows 7 offline", as you will never ever have a problem with the Aero-Design in contrast to "VMware Workstation". There is no problem having both installed, you can even use them parallel:

On the left monitor is "Win7 Offline within VirtualBox" and on the right monitor is "Win98 within VMware Workstaion" both running under linux:



However, when you want to use any "macOS" the best possible way is the use of "VMware Workstation", by the way: you will never get the same power, as with other virtual machines, but it works in order to mess around with macOS within a virtual machine. In this case "VirtualBox" is much too awkward to use for macOS, it is not worth to torture yourself!

The best thing with "VMware Workstation" is the unofficial tool "Unlocker 3.0.3 for VMware Workstation", which does anything you need, so that you get an additional entry for Apple Virtual Machines.




You will find the macOS-ISO for "VMware Workstation", thus there should not be any big issue to use it; there are always some little traps to solve, but it is not a big deal!


1. DL and install VMware Workstation "VMware-workstation-full-16 1 0-17198959" - you will find a key, won't you?!
   It is possible to DL directly, without the need to register!
   This is the german link, but you will find the DL-button:
   "Workstation 16 Pro for Windows" => "Jetzt herunterladen"

https://www.vmware.com/de/products/workstation-pro/workstation-pro-evaluation.html


2. execute unlocker as admin via termnal if needed "win-install.cmd": VMware Workstation will be patched and "darwin.iso" downloaded into the folder "tools" within "unlocker-master":



Just as as an example, this is the abridged terminal outcome of my linux terminal:

Code: [Select]


ubuntu@ubuntu:~/Schreibtisch/unlocker-master$ sudo chmod +x /home/ubuntu/Schreibtisch/unlocker-master/lnx-install.sh
ubuntu@ubuntu:~/Schreibtisch/unlocker-master$ sudo bash /home/ubuntu/Schreibtisch/unlocker-master/lnx-install.sh

3. install macOS, the way it is necessary for "VMware Workstation"
   => this is for "el capitan":
   
https://techrechard.com/install-mac-os-x-el-capitan-on-vmware-on-windows/

   => and this for Mojave with some links, but it is always the same procedure for any macOS:
   
https://www.aioboot.com/en/macos-vmware-workstation/


4. within macOS you have to load the "darwin.iso" into the virtual CD-drive, in order to install "VMware Tools",...




As soon as you click save, you get, the message to install it:




...to get the drivers you need to run macOS; during this you have to allow it in the security settings and reboot




I was always able to update any macOS, however, before doing an upgrade, I do a clone of the former macOS version, to keep it and then do the upgrade with the clone, in case anything gets wrong: "I copied it!" must be clicked, when there will appear a message!


Cheers!

this is actually a LIE, (about being 'damaged'), and it is actually due to Apple trying to STOP people from trying to install older versions, date-wise

That is just paranoia... It's a date-expired certificate inside the installer that's all. All you've got to do is set the clock back before installation. To suggest this was deliberate rather than an oversight is definite tin-foil hat territory!

[Bicurico]

Because what you want to do is illegal anyway - at least it does void Apple's terms, why not downloading a torrent with a ready to go MacOS virtual machine. Don't put any sensitive data inside it, though.

[Keith956]

It would be far easier to buy a cheap Mac Mini off eBay and use that rather than trying to faff around with VMs and all the compatibility issues they bring.

To 'PushUp'... I'll thank you, and get to your in-depth & great answer shortly, in another answer!!!   

Firstly to 'stevelup'... I'm aware, as I stated in my original post, that this is a 'Date Expired' issue, after looking up that problem on the Internet.
However, I was not Paranoid, about the error that was displayed.  It specifically stated that "This copy of the install macOS High Sierra application
is damaged and can not be used".  With no mention of a Date/Version/Timeline issue! That is deceptive, especially for the likes of myself who knows
nothing prior to this whole exercise, about ANY Mac systems, or OS Versions...     I had since found out that changing the Date to a 'false' one, also
circumnavigated this problem, without the suggested file 'Edit' I had initially stated. Initially, I changed the date on my Laptop, which did not work!!...
I then found another Site that explained how to do it during the setup of the macOS, in the Apple disk utilities window for formatting drives etc...

I was able to select from the initial Apple menu a 'Terminal' screen, from which I could use the 'date' command to set a fake 2018 date, just for that specific
Virtual M/C, and after that, the 'Install' progressed properly as it should!!!

Yea, I know. However, I'm not personally 'troubled' by ANY legal/illegal issues, as those old OS's are freely available, even from Apple,
and I have ZERO commercial gain from simply using an old 'Virtualized' OS purely for self education/interest... 
'Experts' on the Net agree that... "What would Apple care??"... "Nothing!!"

[GlennSprigg]

And now on to 'PushUp'...
Thank you for your wonderfully descriptive answer, that was beyond the call of duty!!!   
I have saved everything from your Answer, and am reviewing it!!...

I'm now perfectly happy with how 'VirtualBox' works, and the things that can be done with it. Now also including the use of 'Virtual' Disk files
that end with '.vmdk' which take a lot of hard work out of other installations from an '.iso' file!!  I've learn't a Shit Load now!!!   

I've NOW seamlessly & faultlessly ALSO set up a Virtual Machine for 'Linux', (a Ubuntu variation). The version is... 'Ubuntu-Mate'...
All went perfectly, and the Specs for that release/version are absolutely incredible, and so easy to use!!!

'Experts' on the Net agree that... "What would Apple care??"... "Nothing!!"

What I meant is that it is easier to just use a readymade container!
I mentioned legality in the sense that it doesn't matter if you download such container as a torrent as it not more illegal than using the virtual machine in the first place.

It would be far easier to buy a cheap Mac Mini off eBay and use that rather than trying to faff around with VMs and all the compatibility issues they bring.

That's dangerous, you could get hooked!

Indeed. I just bought a Mac Mini 2012 for £150, it came with 8GB RAM (can be upgraded to 16GB) and a 500GB SATA hard drive (which is painfully slow). This will run Mac OS up to Catalina out of the box, and Big Sur by using OCLP (OpenCore Legacy Patcher). I replaced the hard disk with a 2TB SATA SSD and went with the latter

This is why Apple now solders everything into the mainboard - no doubt we will see a fully potted Mac at some point!

I wouldn't be surprised, either, although I think the next step will be a Mac computer with the inside encased in glue or some sort of resin. And certified repairers will need an Apple-branded mini jackhammer to do any repairs

I ran a Mac OS Sierra on a virtual machine on Ubuntu VirtualBox... But I had it easy, all I did was download an already made virtual machine by TechRadar.  One of the steps I remember is having to "fake" a hardware serial number otherwise the system wouldn't boot. So a quick Google image search found some Macs being sold with good enough photos of the backs to show some examples to try out. 

It worked, App store and account login functional, podcasts and videos all ok. However any apps that rely intensively on graphics didn't show anything (blank)... Tried some games and graphics apps from app store and didn't work. However WhatsApp and some others were fine. All in all it was a fun exercise and then I went back to using my Linux machine and never touched the Mac VM again.

Take a look:

Thank you edy, for your reply. 
In the end, I gave up using 'VirtualBox' as a MacOS guest, as there were too many problems.  HOWEVER, using 'VMWARE' Workstation
'Player', (the free version), and modifying it with a free downloadable copy of 'unlocker', (easy to find!!), which enables a multiple of MacOS
guest installations, certainly worked the best in the long-run, when actually using the MacOS guest!!   

Yes... there are problems running certain graphics intensive software, and that is it's limitations re: the Virtualization...
