    hard drive errors in Disk utility.? APFS issues?
    I had difficulty getting my macOS hard drive to boot.... I booted from the backup drive, I ran disk utility and it said all is ok, after finding some errors and "warning: found physical extent corruption but repairs are disabled"?? the disk appears to be ok. with a green check mark.

    how are repairs disabled? I ran tech tool pro and it's not finding any issues...

    never had all these issues showing in Disk utility until I installed Mojave and it's converted the hard drive to APFS... not sure whats going on or if I need to do something or worry about it? lol

    There are sections of the boot drive that cannot be repaired because you are booted from it. Boot either from an external drive with the OS on it, or the Recovery Partition. Hold down Option while booting until the options appear. If there are no options, you will have to create a bootable drive.

    If you were running High Sierra prior to your upgrade to Mojave you should have been running APFS already unless you opted not to convert in the installation process.
    I personally performed a clean install of Mojave, that is I erased my HD installed Mojave and restored all of my data from a cloned backup.
    I do not do this at updates or indeed every upgrade but it would most likely fix your problem if you wanted to go that way.
    I cannot claim to fully understand the error messages you have from Disk Utility so I cannot say if they are serious enough to warrant a reinstal. Perhaps someone else can chip in with some advice on this.

    Do you know if your startup drive is an HDD or SSD?

    Please backup. Everything has a life cycle, unexpected and warning free. Nothing will last as long as you want it to.

    hdd drive, mechanical. it was not APFS until the Mojave install then it converted to APFS just did it without asking me. This mac is not even 3 years old yet so I hope the HD is not going bad. I may boot from the recovery OS and run disk utility from there. I never got any errors in DU with high sierra.

    My recovery partition has high sierra on it, not Mojave. I'm tempted to go back. I had no issues with High Sierra.

    Ive booted from my backup drive now. its also showing similar errors in disk utility. I keep getting this screen when trying to boot from main drive.

    not sure how to fix this? should I install high sierra from the recovery partition? will my data be lost? I have a backup of the data.

    what to do? I need to get my main drive booting again...

    When upgrading to Mojave, (if you didn't do a clean install) the Recovery partition will not be updated. However, that's easily overcome by running Carbon Copy Cloner which will create one for you.

    As for the kernel panic you're getting, it's probably because you're trying to boot with a backup that's formatted to HFS+ and your hard drive is now formatted to APFS. No can do.

    Run Carbon Copy Cloner and let it create a Recovery partition for you and then afterward you can use disk utility normally. Do not try to go back to High Sierra.

    You need to make a backup clone of Mojave using CCC and it will offer to create a Recovery partition for you. Using your backup drive is not going to work.

    Im booted from the backup with Mojave on it. internal HD wont boot. well it booted shortly in safe mode then it went out. so the backup is booted. so you're saying run CCC and backup the bad drive to the external that is working?

    here is what chscag said in a PM. trying this first and going from there.... posting here for the sake of maybe helping others...


    "you have a problem if you can't boot your internal hard drive. You need to fix that first before worrying about a Recovery partition. Okay, do this:

    Try cloning your backup of Mojave to your internal hard drive and then see if the internal hard drive will boot. We can go from there"

    chscag, it worked. main internal Hard drive boots now... I ran disk utility which locked up, soon as it finished the computer rebooted, then another time after a few minutes.... something is still wrong... how do I find out what? thanks for your help appreciate it!

    I have tech tool pro 12... some parts of that I cant run its not compatible with APFS... wonder if tech tool caused all of this?

    per one article I found, I booted with command opt P R to reset the parameter ram... so far its stopped the rebooting issue...
