My 2013 27″ on Catalina 10.15 is operating out of disk area. The inner 3TB HDD is damaged and I’ve saved it working by splitting the fusion drive and operating it off the nonetheless functioning however very small internal128GB SSD.
With a purpose to obtain a brand new OS and create an installer, I made a decision to make use of Carbon Copy Cloner to clone the set up onto a brand new 480GB SATA SSD, linked by way of a USB to SATA adapter.
The CCC course of went easily and it created a clone in about 25 minutes.
When I attempt to boot from from the clone, the SSD is recognised on the boot picker stage (holding down the ALT/OPT key on boot) and it begins besides however when the progress bar has gone about 3/4 of the way in which throughout the iMac simply shuts down.
I’ve used CCC for years and at all times discovered it tremendous dependable. Has anybody bought any recommendations on the right way to troubleshoot this one?
