Hi

Don’t worry about the format of the drive - the limitation comes from Time Machine rather than ?WD hardware (see this article -?). ?Should Apple update Time Machine to support APFS in future I imagine they’ll provide a migration path.

As for what to do for backup, personally I’d stick with Time Machine - from the “it just works” point of view if no other (though the ability to pull a specific file out of the backup via Finder is also very handy). ?If you have the spare disk capacity making a Carbon Copy Cloner or Super Duper bootable copy is a nice to have - but if you can only have one I’d stick with time machine.

Regards

I have been out and ?bought a 4tb Seagate drive that the Seagate website says is Mac and Time Machine friendly, and currently it is setting up as a new Time Machine for me.?
I figure this should be an improvement on the WD drive which the WD website info says stopped being supported at Sierra....that was news to me.

However...... reading the small print for the new Seagate thingy it says it needs to be formatted HFS......so how are we going to get on when/if going to Catalina which is a whole new ballgame APFS?

I'm having a further rethink --- should we abandon TM altogether and go for a clone that updates....but for now I am letting the new one do fresh TM and I might then reformat the WD drive and maybe do a clone as well..

The WD drive incidentally was only 13 months old..... and it might be the culprit behind my iMac Pro lagging when it gets to three quarters down the start up bar ?in starting up and lagging in shutting down perhaps.?
