Unfortunately, due to the way Boot Camp (especially its partitions) works in conjunction with APFS, you cannot arbitrarily resize either the Boot Camp partition nor the APFS Container once both are present on the same device; the only viable method for reallocating capacities is destructive to the Boot camp partition.
Back up your Boot Camp Partition (use ...
Boot camp assistant is not allowing me to reduce the Windows 10 partition size to a value lower than 48 GB.
That sounds about right as a practical lower limit for Windows 10. The Microsoft system requirements you're referring to are the absolute minimum resources required for the operating system to be installed; using Windows with that little disk space ...
THere's nothing actually wrong with your Air's EFI, what you are experiencing are the death-throws of a failing-and-fading-fast SSD module.
We tend to be rather blasé about solid-state drives these days, but seven years ago the technology was still maturing, and SSDs were still susceptible to sudden and inexplicable demise. When Jobs decided to start ...
Have you try these steps to fix your issue:
$ diskutil list
It will list your physical drive detail. Note the drive name for unallocated space.
sudo diskutil eraseVolume "Free Space" %noformat% /dev/disk0s3
Assuming your volume is named disk0s3
Next, resize your APFS Container
diskutil apfs resizeContainer disk0s2 0
With value zero at the end, ...
Basically, your question is a duplicate, which has be asked many times before. For example, see the question: The startup disk cannot be partitioned or restored to a single partition. Windows 10 and Mojave
I repeated my answer below. The answer was edited to more closely fit your question.
This is a very common question. Again, here is the commands you ...
I usually use the Disk Utility tool to do this, because it shows the process quite clearly. It should be located in /Applications/Utilities/Disk Utility.
You might need to erase and/or reformat the partition before you can actually merge the partition. It's been a while since I've done this.
This article has a nice overview of all the necessary steps: ...
If you are shrink you main volume, open 'Boot Camp Assistant', click 'Continue' and it will be stuck for a while and go error. Then quit it and you should be able to shrink.
I think it was doing some reclamation, but I don't know if there is a more direct method.
I had the same problem , i did reinstall mac os (Mojave) but problem not resolved.
Finally i solved using this.

After all you can see like as appear OK
Type reboot and hit enter

is it an apfs vol?
did u try to partition the volume without a specified format?
please post more info !!
off the top of my head i can think of a couple of things, mainly
diskutil eraseVolume /dev/diskXY (where X= the disk and 1 the volume within that disk) "Free Space" "%noformat%" <desired amount, %, or if you've already created a separate volume use ...
I had a similar problem with a Sandisk 32GB SD card. I solved it with the Windows management disk. I erased all partitions of the disk and then created a fat32. Initially no drive letter was assigned but then from My Computer, format the drive without problems.
My SD card had this problem after using it for a raspberry pi.
Uhh. I was getting this error in the logs:
Mft record size (1024) is smaller than the sector size (4096). This is not supported. Sorry.
At least they apologized. I was formatting the bootcamp partition with "format /q c:" in winpe. (I'm imaging it with dism.) It turns out I had to do
format /l /q c:
to get the 4096 mft record size. Then osx won't ...
