Not Able create a boot disk from Mojave. Could be an issue with ASR, Apple Software Restore.

May create a fallback to CreateInstallMedia for older systems.

Looking into it. No promises.

Workaround, try creating the install disk from Catalina or Big Sur.

How do I make an install disk from Catalina or Big Sur if I don't have them :-(?

StarPlayrX commented 3 years ago

You create it from BigMac, see the readme, screenshots and video.

Ofcourse, but as you stated it does not work in Mojave. I only have Mojave macs here, maybe an older Sierra but I guess it won’t run on that.

The boot disk creation part currently does not work on Mojave and that is being looked into as to why this is.

In the meantime, for those with access to Catalina or Big Sur, the installer boot disk can be created there and this USB disk can be moved to a Mojave Mac. This can even be done from a supported Mac as long as SIP is disabled.

Now you can use Open Core Legacy Patcher, aka OCLP, on its own directly from Mojave; along with createinstallmedia USB from Apple.

This issue with 10.14.6 is its discovery phase. No promises. More than likely the command line version of the original bigmac will be updated and tested with Mojave first.

If you look at the legacy branch of Bigmac2 there is a command line utility to create a USB boot disk which should work from Mojave as well. Its download URL will need to be updated to 11.2.3. You can get that by googling Mr Macintosh dot com, Big Sur.

Last of all, you can download Dosdude1's Catalina patcher and download and start Bigmac2 from a fresh install of Catalina. Catalina is the closest thing to BigSur in terms of programming and it is recommended to be on 10.15.x anyways, unless you can create the account install media elsewhere.

I did just that! I am as we speak downloading BigMac2 trough a SSD installed version of Catalina. So I hope that works 🙂

Please don't get me wrong! I really love what you are doing here and appreciate your efforts in this project!

I will let you know if I was successful with installing it this afternoon.

Thank you.

Hope it works out for you. Lately, I've been using a combination of Bigmac2 2.0.5 with OCLP, but I am already on Big Sur which helps.

Beware of race conditions in macOS 11.3+ including Monterey.

Recommend 11.2.3 to start.

Once you get on 11.2.3 things get to be easier.

To disable SIP from a Bigmac2 install disk, use it on an external USB or a 4x slot in a Mac Pro 4,1 SSD PCIe OWC card.

Obviously you can disable SIP from Mojave if you can get into recovery mode or create installer disk media using Apple's command line method.

I do plan on making this even easier. Time is just valuable for me right now. I do appreciate all the support from users on GitHub.

Oh an you can partition disk with bigmac2 on the first 32 go partition and the installed OS on the second.

I do this a lot when testing and I use this if I want to do an unsupported install from a supported Mac. In this case SIP must be disabled from the supported Intel Mac's recovery. And enable it when done with bigmac.

Unfortunately alternative this method no longer works with M1. At least it seems to be broken right now.
