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

Even better, my iPhone and iPad have been updated to iOS 12, and I can no longer connect them to iTunes on my High Sierra Mac. So to manage music or any other content, or access photos on my phone or iPad, I need Mojave, but I can't install Mojave without losing BootCamp.

That is beyond bogus.

(And BTW, I have a replacement drive, not the original, though it is a 4TB rather than a 3TB)

I think you mean anything OVER 3TB - mine is a 4TB replacement, and no love here, either. The real kicker is that with my iOS devices upgraded, I can no long manage or access content on them (iPhone & iPad) without upgrading to Mojave, but I can't upgrade to Mojave without losing BootCamp.

I have upgraded to iOS 12.1 on my iPhone 6 and my iPad and my Mac Pro Mid 2012 to Mojave v. 10.14.1.

Every thing is ok: backup with Photo and sync with iTune. In addition I use iMazing v 2.7.2, greate app.

I confess I can't follow the technical discussion on getting access to Bootcamp from an external drive, and I wonder anyway if the drive would respond quickly enough to run programs but ...

Is it as simple as copying the existing Bootcamp (with its Windows programs) to an external drive and then installing Mojave? I rather suspect not and I'm very reluctant to delete my Bootcamp and the one Windows program I want to keep.

Hey dialabrain. I appreciate your high standard for Apple folk, but they are humans, if pretty well-trained. If you have any extensive experience with Apple Genius Bar, like most of us here, you probably have experienced that they opine often. I have not heard THIS statement, but I have heard other things very much like this that would certainly be considered 'off script' or ill-advised. So as to the comment from JamesfromWeybridge: I love Apple, but I believe that he heard something like this if he says so.

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.

It would be good to explain what APFS conversion entails (what does it mean) as this apparently interferes with bootcamp and time machine.

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

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.

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.

It may need an update. You can ask if you haven't already.

One has to wonder why the partition scheme for a 3TB Fusion drive would be any different than for a 1TB or 2TB Fusion drive. Both of which I have and work fine with Mojave.

It's very annoying that apple didn't forewarn users of this.
