Hi, I have a 2013 late Retina Mac which is 512GB SSD. I have taken its Time Machine Backup. I have a 2012 Retina iMac, where I installed a brand new 240GB SSD. Now, I need to restore my Retina MacbookPro Time Machine to this new SSD of iMac. But it says, no space left . What to do ? IS there a way to restore ?
