I would recommend getting the SSD and enclosure from OWC. You can put the HDD into the external enclosure so you can transfer your files to the SSD. Remove the HDD from inside the computer and replace it with the SSD. If all is well, remove the SSD from the enclosure.


Do the following:ĭrive Partition and Format - El Capitan or Later You should be alerted that the external disk is not yet initialized. Install the SSD into the enclosure and connect it to the computer. Get an external enclosure supporting USB 3.0. Please forgive all the questions don't want to screw anything up, and don't do this every day :-) Then I copy to my new SSD using Carbon Copy Cloner, yes?Īfter that, is there any way I can get High Sierra? And if so, what do I need to do to put that on the new SSD? Can I download it, then use CCC to transfer that over to the new disk, then install it on the new SSD? Perhaps then boot from the drive to make sure that all is OK, then just install it in my MB Pro? (Mid 2010, core 2 duo, which Apple says will run High Sierra) So just to be clear I use Disk Utility to "Erase" the drive on the new SSD? Do I use "Journaled"? Extended Journaled? With GUID partition map, yes? I have an OWC Mercury Electra 1 TB I have it because I want to add some software that needs High Sierra, and a larger capacity to also run Elementary OS I have CCC to copy El Capitan to my new SSD from my current one (SanDisk 256 GB) Format new OWC Mercury Electra SSD want to put High sierra on it.
