Hey Everyone, First time poster, long time lurker. I have an iMac late 2013 1 TB HDD. I just bought an external 1 TB SSD that i'd like to create a mirror copy of my current HDD and put it on my SSD and make that my primary drive. Then i'd like to format the internal HDD and use that for storage. Basically i'd like to swap their data for speed purposes. Any suggestions on how i should go about doing that? I know I should format the SSD first for mac. After that, what would i do to transfer a mirror copy to the SSD, boot from the SSD, then format the HDD. Thanks in advance, sorry if this is a dumb question. The only tutorials I found didnt tell me how to make a mirror copy. Only how to install mac OSX to the SSD.
