Bootcamp will not recognise x64 Windows 7 ISO or Install Disc

So NONE of these answers here solved my problem... what DID solve my problem was a solution I found here:

https://superuser.com/questions/908485/boot-camp-assistant-not-accepting-windows -10-iso-file/1082308#1082308?newreg=cea0…

here it is curtesy of Jeremy Banks:

The System Integrity Protection in newer versions of OS X prevents modification of Boot Camp Assistant.app/, as suggested by other answers. I tried duplicating the file and I was able to modify the duplicate, but it didn't fix the issue for me.

I solved this problem by tricking Boot Camp Assistant with a Windows 8 ISO.

Download both Windows 8 and Windows 10 ISOs from Microsoft (you don't need a license to download the installers).

Create a copy of the Windows 8 ISO and name it windows.iso.

Select windows.iso in Boot Camp Assistant. It should accept it.

When it prompts you to confirm that you want to format the disk, wait.

Delete windows.iso.

Open the Trash, right-click on windows.iso and select "Delete Immediately". (Emptying the Trash will fail because it was already opened, but specifying it directly seems to avoid this.)

Rename the Windows 10 ISO to windows.iso.

Return to Boot Camp Assisant and confirm, to continue the process.

After using the Windows 8 ISO to pass the verification process, it can successfully use the Windows 10 ISO we swap in to create and use an installation disk.

good luck - this is the only thing that worked for me.

I had a similar issue -- the iso file I downloaded from Microsoft wouldn't "load" while using the Boot Camp Assistant. I guessed it was something to do with the long iso file name (which was "Win10_1607_English_x64.iso"). In the Mac Finder, I duplicated the iso file and changed the name (to"Win10_64.iso"), then the iso file loaded fine and I was off and running.

You need a 64-bit only Windows 7 ISO. Mixed versions aren't compatible with the Late 2012 iMac (I suppose that they contain 32-bit files that Boot Camp detects, refusing to use that file). Download a 64-bit only Windows 7 ISO and it should work correctly

I had the same problem, and found the solution on MacRumours, posted by one "falkas", to whom all credit is due. I tried it, and it worked first time, like a charm.

It is possible to use the Windows 7 ISO with both x86 and x64 on the same install file. Bootcamp 5 will see this as a x86 install file though and won't allow it to continue. To fix this just follow these steps.

1. Open a Finder window.

2. Navigate to Applications>Utilities

3. Control Click or Right Click on Boot Camp Assistant and select "Show Package Contents"

4. Open the Contents folder

5. Drag the file "info.plist" to your desktop (I also recommend saving it in another place as well in case you want to revert to the original)

6. Open info.plist on your desktop with a text editor

7. Find the field labeled as below:

<key>32BitSupportedModels</key>

<array>

<string>MacBook7,1</string>

<string>MacBookAir5,2</string>

<string>MacBookPro10,1</string>

<string>MacPro5,1</string>

<string>Macmini5,3</string>

<string>iMac12,2</string>

</array>

8. Time to find what your Mac is. Click the Apple in the top left hand corner and select About This Mac

-Click More Info...

-Click System Report...

-Under Hardware Overview, look for Model Identifier and copy it

9. With your Mac's Identifier copied, go back to your open info.plist file create a string at the TOP of the entries. So if your Mac identifier was "iMac13,2" then it would look like this:

<key>32BitSupportedModels</key>

<array>

<string>iMac13,2</string>

<string>MacBook7,1</string>

<string>MacBookAir5,2</string>

<string>MacBookPro10,1</string>

<string>MacPro5,1</string>

<string>Macmini5,3</string>

<string>iMac12,2</string>

</array>

10. Save and close info.plist. Drag info.plist back into the Contents folder and select replace. (You may have to authenticate and enter your admin password).

11. Start Bootcamp and it should allow you to use your Disk/USB with both versions. I wouldn't recommend installing the x86 (32 bit) version of Windows 7, but this will allow you to get to the point of the installation to select x64 (64 bit) if you have an ISO file with both 32 bit and 64 bit combined. Hope this helps.

I have tried using this method explained by Akominatus, however when you get to step 9.

9. With your Mac's Identifier copied, go back to your open info.plist file create a string at the TOP of the entries. So if your Mac identifier was "iMac13,2" then it would look like this:

The info.plist file is locked and you cannot make changes to it.

error message

You don't own the file "Info.plist" and dont have permission to write to it.

You can duplicate this document and edit the duplicate. Only the duplicate will unclude your changes.

The duplicate does not save as .plist as it is in text edit.

This is getting rather confusing because now we are in another topic of editing locked .plist documents.

I'm not sure what is going on but I am running a new mini with no changes made to it and the error message comes up where as I do not see other people running into this .plist problem.

Any advice to get past step 9?

You need to stop the Boot Camp Assistant which might be running (assuming you are part way through the setup process). I had the same issue until I realized it was running.

You will also need to authenticate the new version of info.plist when you save it back to the contents folder.

I tried doing what it says here and now my boot camp wont open?

I also tried your proposition, but afterward, my BootCamp wont open as well.

Akominatus i tried what you have mention but after that my boot camp stop working so i had to revet back the info file any other solution or can you suggest where we are going wrong ..

Thank you

Hello!

I have the exact same problem, does anyone has a workaround for this?

Thanks!

After change info.plist my BootCamp wont open too :/

Or just download the x64 ISO vs the work around

The problesm with this "fix" is that it will UNFIX your Bootcamp assistant because you do not have the code signature/ right to edit this Plist. If yo do edit it BootCamp assistant will crash on you over and over and over again until ..like me you happen to be smart enough /luck enough to have created a time machine back up that can restore the original file. A copy of the file you make WILL NOT work ...it must be untouched.

I agree, messing up with the info.plist enables to start the windowns install; but for me it stopped in the middle of the installation afterwards; so it is not a working solution (I tried on a MBA 2013 and a MBP 2013)

Solution was to download a x64 ISO (recognized by bootcamp without a problem) and then follow the bootcamp guide.

i just had this same issue. I found that the problem was that i had the disk mounted on my computer. once I ejected it, it worked without issue.
