Thanks for your reply, it’s extremely informative and useful. It’s actually the second time I’ve resized the APFS container and this didn’t happen the first time. I was also shocked to wake up this morning to discover the resize had actually left me with a new partition, considering that every time I tried to resize it, the process failed with a well documented error code or the machine just spontaneous rebooted while frozen. One other question I have is, that once I’d installed Fedora, my Mac would automatically boot into Fedora. So now if I want to use macOS I have to use the Option key. Has the Fedora boot loader over written something and is it even possible to swap it back? I’m going to give the net installer Rescue a bash now. Thanks.

Fedora's installer wrote a new boot entry to NVRAM and set the bootorder to default to Fedora. If you boot Fedora you can run efibootmgr -v to see these entries and change them with 'efibootmgr --bootorder' and then put in the boot numbers in the order you want, e.g. 0002,0001. If you make macOS first, then it will boot by default, to get to Fedora you'll use the option key at boot time to pick its icon in the firmware boot manager UI.

  Sir, you are a genius and the most useful person I have ever discovered on the internet. Thanks!

  This boot ordering I could not get working, but perhaps it was a symptom of the missing grub.cfg, but I'm just guessing. I have no desire to temp disaster by playing around with anything now that it's working. Thanks again!
