No Boot Camp on Mojave??? ***?

Is there a chance that Apple will fix this issue eventually as it did when the 3 TB drive was first introduced on the late 2012 iMac, or are there incompatibilities that cannot be fixed?

It is certainly bad, as I thought I had a future proof system, especially with the 3 TB replacement drive a few years ago.

1. Only Apple knows.

2. There's no such thing as "future proof".

Hey, sorry for a late response to you’re issue. It seems like macOS Mojave doesn’t support Boot Camp for you’re Late 2012 iMac. That sucks I know but, there is a way to install Microsoft Windows®️ on you’re Macintosh.

Step 1: Retrieve a disk Copy of Windows

Step 2: Open Disk Utility on Mojave

Step 3: Click Macintosh HD or whatever name you have for you’re Macintosh’s hard drive and click partition.

Step 4: Partition how much space you would want on the volume you are partitioning and when you’re done getting you’re space setup before clicking Apply, click name and name it Windows and then click format and format it as exFAT then click Apply.

Now insert you’re DVD copy of Windows ®️ And wait for you’re iMac to detect it. After that, click restart and as you’re iMac is restarting hold down the option key on the keyboard. When a boot menu of 3 comes up you may see EFI Boot, you’re Mac hard disk and The Windows DVD, click the DVD and when you’re going through the setup and get to the select disk section, click the disk that says Windows and click drive options then click Format. This will only format the Windows volume so it can be recognized so you can install Windows on it. Then proceed with the installation of you’re choosing of Windows ®️

The following isn't regarding 2012 iMacs but after spending time trawling the internet looking for a solution and trying all kinds of things, I have posted this here in the hope it helps someone else.

I spent a long time trying to get Boot Camp to behave on my late 2015 i5 iMac running Mojave but it just wouldnt get past the partitioning of the disk phase in BCA. It would error within a minute or two.

I then tried the manual route, successfully created a partition, booted into Windows using a bootable USB but then Windows had issues in the 'Copying Files' phase of the install and would error there too!

I tinkered a while and eventually broke my OSX install completely by accidentally deleting a partition of the Fusion Drive. Great.

As always, I have a Time Machine external drive plugged in at all times and decided to start again from scratch restoring a backup from 2 days before.

After a few hours, restore completed and everything was back where it had originally been.

Tried the BCA again and shock of the century it worked first time so I now have Windows 10 Pro and OSX Mojave running together like old friends.

The cure? I couldnt tell you, if I'm honest but if it worked for me, it may work for you!

Time Machine + start from scratch = Happy New Year!

What if you already have Windows10 Installed on your Mac already? I have been using boot camp and then Parallels to use Windows to run my business software and now am unable to get to it because of the update! Its year end and need to finalize my books! I keep getting an error message from windows went I open boot camp and it will not repair its self. (if it were a PC I could fix it) I was thinking maybe I need to download windows. I already updated Parallels to make sure that wasn't the problem.

Any help would be appreciated.

Thank you

I'm having the same issue on a late 2014 model with the 3TB drive

Can you look at the second post on this page? Also, a 2014 model can support EFI Boot, so you do not need to use the default MBR method that BCA uses.

Hi there,

I can state that this is not working on the IMac Late 2012 with Fusion Drive 3TB!

I've tried the above mentioned but it all comes up to some error :/ ...

I even have reseted the Fusion Drive itself and tried the above booting from legacy and EFI but I'll always get an error or because the MBR or about the windows EFI.

There could be some work around but it should be simpler...

Cheers,

You can always go to a website that has modded versions of the Parallels application so you don’t have to pay for the software that website is nmac.to

However it looks like you will need to reinstall macOS/OS X on you’re Macintosh. You’re best bet is to have another Macintosh computer or borrow a friends and download the InstallESD.dmg file for macOS Mojave.

However, in the event that you have a Windows PC, google hackintosh.downloads macOS InstallESD and click the hackintosh.downloads one. After choosing you’re version of macOS Or Mac OS X, download TransMac for Windows. Now you will need at least a 8-16GB usb flash drive, MAKE SURE THERE IS NOTHING ON IT BECAUSE EVERYTHING WILL BE ERASED. When the macOS or OS X InstallESD.dmg is done downloading as is TransMac, open TransMac and then plug in you’re USB Flash drive to you’re Windows PC. Right click on the tab with the flash drive and click format disk for Mac. Then select the InstallESD.dmg file from wherever you downloaded it and saved it to. After that, wait until the process is done (side note: it takes a while) after everything is done, just pull out the USB Flash drive from the Windows PC don’t worry about ejecting it. Now while you’re Mac is off, plug in the USB Flash Drive. Now as soon as you turn the Macintosh on, hold the option key on the keyboard until you see a grey screen with 2 little logos on it. Click the flash drive.

NOW PROCEEDING TO THE FINAL STEPS WILL ERASE ALL YOUR DATA ON YOUR HARD DRIVE.

Now, remember how I said you should download macOS Mojave because it’s the latest version, will that’ll help you in the long run because if you didn’t, then when trying to install anything below Mojave, you will get an error but there is a work around that. But now what you will do is click utilities, then click disk utility, click the hard drive at the top and click erase BUT WAIT before you do that, make sure before you click the final erase button, you named your Hard disk something like Macintosh HD or anything and make sure it is set to Mac OS Extended Journaled or else it will not work at all. Then click erase. Now close disk utility by pressing command and then Q on you’re keyboard. After that, click install macOS and click whatever you named your hard drive and you’ll be on your way. Just remember whenever your Mac starts up in that install process, anything after that click Macintosh HD NOT YOUR FLASH DRIVE BECAUSE THAT WILL RUN THROUGH THE ERASE PART OVER AND OVER AND OVER AGAIN. Hope that helps!

Because Mojave is fine on a Late 2012 iMac. I just installed it on mine. What isn't fine is one particular model of iMac and Boot Camp. I'm sure there is some technical reason.

Does your computer have a fusion drive?

Yep. 1TB.

You're welcome. I seriously doubt Apple purposely abandoned one specific iMac. I think there is some unexplained reason. Parallels and VMWare make very useful virtualization apps.

Yes, I've seen the error message previously.

I have the same issue with my late 2013 with a 3 tb fusion. Frustrating...

And just to make matters worse it seems that Mojave doesn't allow Blurb's BookWright to work either.
