Cloning Mac HDD to SSD - whats the best way?

I want to upgrade my iMac from a HDD to an SSD for a speed boost. I have done the same with Windows HDDs to SSDs without any problems.

However, I am completely unfamiliar with the unique internals of an iMac. I have an excellent online step by step of what to do with the hardware, but once I have the existing HDD in hand, what best to do with it?

Ideally, I would be able to use a Windows machine, and plug in the Mac HDD and the blank SSD as second and third SATA discs, and coordinate the cloning of the Mac HDD onto the new SSD on the Windows machine. Would this work?

Otherwise, what are my options, since I do nto think my iMac has an eSATA port etc?

Many thanks,

Hello Damian,

Cloning feature is currently available for Windows systems only. However, you can migrate the data from the old HDD to the new hardware using the following approach:

  1. Back up your hard drive to an external storage media, such as Acronis Cloud, USB drive, or a network share.
  2. Turn off your Mac, and then replace your old hard drive with a new one.
  3. Boot your Mac by using Acronis bootable rescue media.
  4. Recover your Mac from the backup to the new hard drive.
