    I have a 1TB EVO SSD which is incredibly slow after two months. I have this in an external USB 3.0 enclosure and finding it impossible to update the new firmware. Has the OSX version been released or is there someone in the UK willing to help me at a cost? I'm so frustrated with the Samsung issue and although I have a Crucial SSD, I really would like to benefit from my investment?

    The firmware update application supports only Samsung SSDs connected via SATA.

    Samsung published an installation guide under
    Samsung SSD 840 EVO Performance Restoration Software

    You should read the manual which comes with the software. It is easy!

    Yeah plug it in to your Mac and update it. May I ask which USB 3.0 enclosure? I have a Mobius 5-bay and it has auto eject issues.

    Yes, it works over Thunderbolt. Another tip: it is a lot easier to run the updates using the Magician software in BootCamp Windows than dealing with the Samsung boot discs.

    The fault for this hassle lies with Apple, not Samsung, for keeping their AHCI driver private.

    Anyone get together a usable USB thumbdrive to use to boot a riMac? I have not had any success with any I've tried.
