@stephenw10 The upgrade failed with the following error: 'failed insufficient space remaining for /boot/loader.efi', which is exactly why I was looking at jimp's fix. Only problem was, the install did a umount on /boot/efi just before I got that error. When it did that, it did not revert the umount so I have been trying to figure out exactly where mine should be mounted. Most posts refer to /boot/efi being mounted to /dev/msdosfs/EFISYS, which I don't have. Based on everything I have found, it looks like it should be mounted to /dev/ada0p1. Unfortunately when I do that I also notice that BOOTx64.efi is missing from that directory. I did find where I can replace that file with loader.efi and rename it.
Before I proceed, I just want to make sure I have mounted the correct location to /boot/efi. When this problem first happened, I did run the df -hi /boot/efi and got the following reults:
