remove partions on ssd imac 2013
I have an imac late 2013 which had the fusion drive replaced with an evo seagate 4Tb SSD drive, at the time I split it into 2 2tb drives but now want to remove the partions and just have the one drive.
Using disk utility will not let me resize or remove these partions and could do with so help as how I can achieve this using terminal instead.
