![]() CCC will not overwrite it.ġ - with regards to Diskwarrior (my side-question), I checked on their website. So I booted from last sunday's clone and sloooowly but surely, it worked its magic !!! I just put this now essential hard drive (A 8.7 years old LaCie Big drive which I have never dared to throw away) into a safe. I looked at CCC's advices (never too late) and the strong recommendation is to keep a bootable duplicate at hand since the mac cannot revert to 10.12 otherwise. YES, my mac has an SSD, and looking at the resource you quoted, YES I use CCC and have two bootable clones, one from last sunday 4th November while my weekday clone, which ran this morning at 00:05 is already overwritten by the new install. It went fine.ĥ - At the end of the process, (1) the High Sierra installer which was in my Applications folder had disappeared, and (2) the Sierra installer 10.12.1 (or 10.12.3, I am not sure) which was still sitting there in my Application folder was rendered unusable.Īpparently, with the sole exception of the above, the mac works normally under High Sierra. No problems either.Ĥ - I restarted on my bootable macOS High Sierra installer thumb drive and installed from there High Sierra (normal install, not a clean install). Reason: I have an iMac to upgrade as well and I want to keep the flash disk installer to be on the safe side.ģ - I backed up, restarted from a Diskwarrior bootable thumb drive (OS 10.12.1 and Diskwarrior 5.0), ran Diskwarrior on my hard drive. ![]() I then created from my main HD using DiskMaker X 7 for High Sierra a bootable macOS High Sierra installer. The process I followed is below it this could be relevant.ġ - I had first installed the Security Update for Sierra consistent with the High Sierra 10.13.0 to 10.13.1 updater.Ģ - I downloaded the macOS High Sierra 10.13.1 installer from the App Store, saved a copy on an external drive, which I disconnected. What did I do before ? Upgrade the day before to High Sierra from a High Sierra installer flash drive (from Sierra 10.12.6). Is there a method for recreating or rejuvenating the recovery HD ? When this thread is over, I will if needed enquire from the Diskwarrior people, but do not believe, so far, that the issue is in their court. Is there anything wrong with my recovery HD ? So the recovery partition is there but does not appear to Diskwarrior Recovery Maker and does not show when I hold down the option key on restart. I restarted the mac again and held down cmd-R while the mac was restarting, the mac booted on the recovery partition. Only my start-up disk appeared, not the recovery Partition. I restarted the mac and held down the Option Key while the mac was restarting. The opened window indicated at "Source OS X recovery disk" that: "No suitable OS X Recovery Disks found". After upgrading to High Sierra (10.13.1), I tried to create a DiskWarrior Recovery disk with Diskwarrior Recovery Maker (which makes use of the Recovery Partition).
