well its done. cannot see too much difference yet...tho have not gone hunting yet.
thank you all for your help.
You see - I knew you could do it!
Now, you'll have to alter the info under your Avatar so that we all remember you are on macOS Mojave.
A further thing to consider - sorry
Part of the reason for creating a SuperDuper! Backup was just in case there was a problem or you hated it and wanted to go back to macOS Sierra.
Sorry to say this, but best practice would suggest that you keep the SD! EHD
and set it aside for a while. Then get a new EHD and make a fresh BU of your new system. This is partly for the reason I mentioned above (going back) and also because behind the scenes there has been a big change.
In Sierra, your files on the Mac were formatted Mac OS X Extended (Journaled). Now, with Mojave, all your data has been converted to Apple File System (APFS). This is good because it makes it quicker and easier to move or copy large files.
The downside for you - sorry again - is that for SD! backups, the EHD should ideally be formatted APFS as well, although the Developer does say that it will work with Mac OS X Extended (Journaled); but "APFS is encouraged".
However, just to confuse you
, Time Machine backups MUST be on to an EHD formatted Mac OS X Extended (Journaled).
In other words, Cloned BUs like SuperDuper! and Carbon Copy Cloner, ideally, need an EHD formatted APFS whilst Time Machine BUs need an EHD formatted Mac OS X Extended (Journaled).
There's always something new to do! Life can be awkward!
