Upgrading to High Sierra and APFS - 06/11/18 12:25 AM
I have a late 2013 Fusion drive iMac running Sierra and was, until spending a distressing amount of time on Google, about to upgrade to High Sierra in preparation for Mohave in the Autumn (er, Fall!). I think I have understood from this research that in installing High Sierra
a) my Time Machine external drive will not be upgraded to APFS,
b) the SSD part of the Fusion drive will be left as HFS+ while the rest of it converts to APFS (although there is supposedly an Apple announcement due “soon†about this),
c) my routine Carbon Copy Cloner cloning and Time Machine backup strategy may, right now, be compromised by somewhat confusing information from Apple, CCC’s developer and others on the consequences of the upgrade, and finally
d) Diskwarrior will not, right now, repair/rebuild APFS volumes.
I have to say that I have never, yet, had to use Time Machine to restore files, never had any serious drive problems that required Diskwarrior repair, and never needed to make significant use of the clone other than to boot from it to run Diskwarrior on the startup disk. In other words, I am statistically due for grief soon.
I don’t know if High Sierra will make much difference to what passes for my workflow but Mohave might. However the above issues suggest that I should remain with Sierra for the time being. Is this right?
