please clarify

I thought I had joined that chat. well, obviously not.

Anyway, I have run through the suggestions in that chat with the exception of the past bit to no avail.

I have not done the "internet recovery logon" as I don't know what that is all about.

Again, the error message just says that there is a problem but not what it is. Then I'm supposed to check and fix my disk with the distil utility. But what am I looking for when I don't know the problem? And since no errors are reported then I would assume that there is no problem. But clearly there is.

Yes, I'm on High Sierra: macOS 10.13.3 (17D102).

I found the Internet Recovery and I have run all the distil tests against both disks and volumes without hitting any errors.

I've had Windows installed under Parallels for quite awhile and it has worked great.

My disk is Model: APPLE SSD SM0512G, Revision: BXW1SA0Q, Capacity: 500,28 GB

According to what I could find about the APFS issues, they do no apply to my SSD disk.

So what is the next step?

I followed your suggestion but got this message:

APFS Container Resize error code is 49153

I googled that and found an entry on the net about this error message at:

macos high sierra - APFS Container Resize error code is 49153 ...

https://stackoverflow.com/questions/.../apfs-container-resize-error-code-is-4915 3

I'll try what you have suggested. However, when I use diskutil (the GUI version) I get this picture of the disk:

It seems that the smaller size is kind of locked. How do I interpret this picture?
