    I've cloned my internal SSD of Sierra to an exact same SSD, and just once changed the start up to check all is OK with the clone. Started up fine, took longer because it's USB connected but other than a few things like 'Downloads' are in a completely different order to the internal one for some reason, seems OK.

    But, since I've checked it out and disconnected the external, the shut down and start up using internal is taking more than twice as long. The white screen before the Apple wasn't even there prior. It started up with the Apple logo straight away, Now it's a good minute before I see it, and as soon as it start up now the fans are on full pelt. Other than 3 x mdworker and kernel task in Activity Monitor, I don't see anything untoward.

    But why after using a different start-up disk and only once to check it out, has it changed the behaviour of the internal disk so drastically, Any idea?

    Just a thought.... Check System Preferences, Startup Disk to make sure that your internal SSD (Macintosh SSD) is selected to startup from. If both your Macintosh SSD and the external SSD are showing, the system may take longer to start because it may be looking for the external, not finding it, and then default to your Macintosh SSD.

    Thanks for reply. No it’s just the one drive as I don’t keep the external plugged in. Was only plugged in to make the back up.

    Carbon Copy Cloner will remove cache files from a copied bootable disk. Refer to its user manual.

    The original bootable disk will still have cache files. The way to delete OS caches from the boot disk is to boot in Safe Mode, then reboot to normal mode.

    Even if the external back up is now not even plugged in? Just doing a clone and unplugging it can change the way the internal disk starts afterwards?

    No, that shouldn't be. Download DriveDX and run a check on your internal SSD. Disk Utility is unreliable when running First Aid on SSDs. Let's see what DriveDX tells you. There may be something going on with your internal SSD.
