Cannot See Boot Camp Partition From OS 10

My 2017 iMac (OS 10.12.6) has some Boot Camp related problems.

I can see and select Boot Camp partition when I do option restart (if and only if Magic Keyboard is plugged in). Windows 10 runs without any problems.

However, when running OS 10:

- Cannot see Boot Camp from preferences when selecting startup disk.

- Cannot see Boot Camp mounted on desktop

- Cannot see Boot Camp in finder from OS X

- Can see Boot Camp in Disk Utility but it is grayed out and I cannot run first aid or mount

- When I look at my internal SSD using disk utility, it shows 4 partitions

Mac HD 830 GB

Boot Camp 160.37 GB

Free space 8.65 GB

Windows Recovery 865.1 MB

- I cannot see Boot Camp from Winclone 6.04 Standard window

Some background details:

Before setting up Boot Camp, I purchased and installed Paragon NTFS for Mac 15.

I then ran Boot Camp Assistant and received the following error message:

"Windows cannot locate the disk and partition specified in the unattend answer file's <imageInstall> setting. Make sure that the setting references a valid partition and restart the installation."

I clicked OK -> message was: "No changes saved"

Screen went black, then OSX restarted

Started Boot Camp Assistant

Successfully restored disk to single volume (only option offered)

I tried again and got exactly the same results.

I had 2 USB HDDs connected but not mounted.

I disconnected all USB HDDs and hubs.

I ran Boot Camp Assistant and it worked.

I installed Windows 10 and it runs without any problems.

I am not sure if the problems listed at the top existed at that time, but I suspect that they did.

Option restart allowed me to select the startup drive if and only if my Magic Keyboard is plugged in. Initially, I did not know that plugging in the keyboard allowed the option restart feature to work, so option restart did not usually work and I was concerned that the computer was not working properly.

I read about problems caused by Paragon.

I purchased App Cleaner Pro and removed Paragon.

I disconnected all USB and restarted. Using Boot Camp Assistant, I removed the Boot Camp partition then reinstalled Boot Camp and Windows 10. This got me to my present state, with the problems listed above.

I opened a case with Apple Support on July 8, 21 days ago. I tried the following procedures with no change in problem status:

Reset SMC

Reset NVRAM

Replaced Magic Keyboard

Reinstalled OS 10.12.6 (without erasing disk)

Ran disk repair multiple times

- 1 problem found and repaired.

- No impact on problems listed above

Apple requested that I record data to be examined by engineering. I did this.

- Sent to Apple on 7/17 (11 days ago)

- No one can tell me anything about the results of the data examination

- I assume that they are stumped or on vacation (I cannot find out which)

iMac (Retina 5K, 27-inch, 2017), macOS Sierra (10.12.6)

Your 'App Cleaner Pro' is not a very useful tool. You must use the Paragon uninstaller. The remnants of Paragon interfere with System Preferences -> Startup Disks.

You can run First Aid only on the macOS partition. NTFS cannot be repaired from the macOS side. Windows Recovery indicates that there is an issue with your installation or it failed and Windows Recovery Console was installed.

Remove Paragon correctly, and then check again. Winclone should see it when there is only the standard Apple NTFS driver on the macOS side.

This is normal and expected behavior when any external storage, except a USB Installer may be needed by BC Assistant. On a 2017 Mac, it is not needed. OSXRESERVED is used instead of the USB installer.

Apple cannot or will not diagnose any non-standard issues related to third-party tools. Try the suggested steps and post any further issues.

Be aware that Apple no longer supports Windows' ability to have read-only access to macOS in BC 6.1 and higher.

I typed the second line and the response is:

The chosen disk does not support resizing.

Do you wish to format instead? (y/N)

Can you post the output of the first command? Do not format.

Can you reboot and then try the mergePartitions command?

Post the output of the 'sudo' command so we can verify.

The mergePartitions automatically should have grown the partition which we should verify. The resizeVolume may not be necessary.

The Freespace partition is gone. Thanks.

Does everything look good to you? I do not know how to interpret the output.

I made backups. When you say re-install macOS, do you mean:

Turn off computer

Start, hold command R

Select option to reinstall macOS?

Yes, but ensure that you pick the existing partition and re-install. Do not erase the partition.

That seems to have worked perfectly.

Is there anything else that I should do?

Please pardon my ignorance. Why would I want to convert the HFS+ to CS?

I plan to encrypt my SSD using FileVault someday before long if this is relevant.

If you use FV2, it also uses CS. You can leave this as is, till you encrypt your disk.
