Two days ago, I received the iMac Pro (8 core, 64gb, Radeon 64, 2tb). I upgraded from an older iMac because I am doing a huge amount of video editing now with vast amounts of video content. First, I installed newest version of High Sierra, then did a full migration from old iMac using Migration Assistant with Time Machine on an external drive. Everything was fine except for one issue, when using the iMac Pro speakers, with each click of the volume adjustment, the speakers had a major "crackle" or "static". This was very odd and concerning. It did not do this on external speakers, only on the iMac Pro speakers. I got on the phone with Apple support, they tried a number of resets and could not figure it out. I packed up the computer and shipped it back yesterday and will be shipped a new one. I just read in another thread about someone having the same issue on their iMac Pro. When I get the new one, I will not use Migration Assistant. Does anyone have any advice about migrating to the new computer, so many settings, applications, etc... Is there any great way to do this other than simply starting over and installing everything one app at a time? Thanks.
