Hi,
I forgot the check the checkbox to upgrade to APFS during the installation of 10.13.
So my Macintosh HD drive is still on HFS+.
How can I do the upgrade to APFS now? I tried re-running the installer, but for some reason, the checkbox is not shown. I can of course reformat and start from scratch, but is there any in place APFS upgrade method for the main drive?
Thanks.
