Is it ture that S.M.A.R.T is not supported for built in SSD for 2017 iMac in Disc Utility?
I don't see why that would be the case - where have you heard it?
Sorry I was unclear. I says not supported on my new iMac but i do not now if it´s something wrong or there is as it should be on the new iMac with nvme SSD.
The SSDs on the new iMacs absolutely have full S.M.A.R.T. support. Disregard what System Profiler may or may not say about it.
The problem is that most of the current S.M.A.R.T. utilities (and Smartmontool) apparently do not yet have support for NVME.
DriveDX has a beta with NVME support which I am currently using. If you own DriveDX you can write to their customer support about it and they'll send you a link.
OWC has a program in beta called Smart Alec that also supports NVME SSDs which you could sign up for but it isn't nearly as elegant as DriveDX.
But it´s normal with "Not supported" for S.M.A.R.T. in System Profiler/Disc Utility for the iMac 2017?
Yes, I am aware of this but that is incorrect. The SSDs absolutely support S.M.A.R.T. and I predict that will be (or should be) resolved in High Sierra.
So the conclusion is that in Sierra an NVME SSD in the iMac 2017 shows not supported and hopefully it will be solved in High Sierra and nothing is wrong with my computer =)
Well, I make no guarantees about the incorrect information in Disk Utility being fixed in High Sierra but I can assure you that the SSDs support S.M.A.R.T. and using the DriveDX beta I am seeing the full list of health indicators for my 2017 iMac's 512GB SSD.
Rest assured there is nothing wrong with your computer.
