Hi Guys, This question has probably been asked a few times before and after reading various threads and posts I am still unsure. Currently awaiting delivery of a m7 512gb SG Macbook. Upgrading from a 2010 15inch Macbook pro 512gb SSD 8gb. So performance should be slightly better is not the same. I have not had to do a clean install in 6 years but have cloned and changed the SSD a number of times. Computer runs fine with no real slow downs. El Capitan made it feel brand new again. My question is: In setting up the new macbook should I: 1. Just use MA to migrate almost everything over? 2. SA to set up as a new computer and then use migration assistant? 3. SA to set up as a new computer and then manually install apps, settings and bring over files? I'm leaning towards 3 but only because i feel a new install will be faster but I have no evidence for this. The most important thing for me to have working properly is OS X mail - It needs to be identical on both computers. Anybody have experience which they could share? Any objective rather than subjective evidence of which method is best? Thanks in advance.
