    Hello, from Chicago. I have a late 2013 MBP. Upgraded to Yosemite from Mavericks. According to my Apple system info, SMART status is verified. But when Onyx does a SMART verification, it fails to recognize. Why? Also when run the disk utility, there is no mention of Smart either. I'm puzzled by this. Could you guys running the same setup do a quick check for me and let me know what your machine reports? Could there be a problem just with ONYX or the way Yosemite reports SMART? Thanks in advance.

    The OnyX developer is aware of the issue - lookie here.

    Thanks! Darnit, I was looking in the wrong forum. I'm relieved now.

    I don't think the dev. will be able to fix it. The Terminal command he is using to access SMART status will not work if either FileVault or core storage is turned on. Yosemite by default is turning on core storage for newer Mac portables like yours.

    Run this command and I suspect you will get the same "Not Supported" message I do.

    Code:
    diskutil info / | awk '/SMART Status/'

    You're right Weaselboy. It says "Not Supported", when I run the command in Terminal. You wonder if the dev can't piggyback onto the info from Hardware - SATA/SATA Express or Storage in System Information where it says SMART Status - Verified.

    So is that the reason when Disk Utility is run under Yosemite that you can't see the Smart Verification like it did before? See this image>

    Yes exactly.

    I think what is happening is that SMART status you are seeing in system report is what was reported at last system boot. I don't believe it is taking a real time SMART status reading.

    I do know some SMART utilities like smartmontools can still read SMART status with FileVault or core storage on though. But this is a third party utility.
