    I’m not sure what SAS card you have, as it appears OWC use Areca, LSI and ATTO SAS inside their LTO drives. You can try manually loading the driver by entering this command into the terminal. You will need to be an administrator Mac user.

    sudo kextload /Library/Extensions/ATTOExpressSASHBA4.kext

    That’s for an ATTO H12xx card. If that doesn’t work you will need the name of the driver used for that card, so let us know and we will see if we can help further.

    Hey John

     

    I had the exact same experience with OWC. They are an incredible company and Tim who has been repping them here can be seen making claims all over the net that BRU is being supported and OWC is dedicated to supporting the solution which I still do not question in intention but it has yet to materialize in the year plus these claims have been made. BRU, in my limited experience is a dumpster fire of non functional GUI buttons and slow speeds (YoYotta was almost double the speed on my M1 hardware with their drive). So I respect OWC as a player and the biggest supporter of Mac upgrade and performance minded folks but this particular aspect of their business is a black eye on their product line and service strategy. My Mercury LTO is sitting boxed up next to me as we speak while my Magstor LTO 8 drive purrs along with drivers I found on a clearly worded website. What a revelation.

    Hey Eli,

    Thanks for the heads up. OWC support has taken more than 2 months to even get to reply to my inquiry. Dealing with them is an absolute travesty, I want to return my drive as I cannot have it work at all. This is a video I just sent their support: https://youtu.be/PZ2cfR_ae58

    Martin, I have a computer that does work with the drive, so it does have the right drivers, it is showing LSISAS3004, TLR is supported, ALL, SAS9300-4i, 016.000.001.000. How do I download this driver for the Mac? If this doesnt work I need to go with a Magstor drive or something, my business simply cannot handle this dysfunction with OWC.

    There are some OWC LTO drives with an LSI 9300 SAS card inside. So a different software driver will be needed. Hopefully OWC can help, as the driver download on their site is just for ATTO SAS cards. Also note that all SAS card drivers needed to be rebuilt to provide support for both M1+Intel Macs. I’m not sure if this has been done for the LSI card.

    Thanks so much Martin. If in the case that OWC Support is unresponsive or even closes my thread like they did on my first try to contact them back in November / December (all they do is tell you to email their Bru email address, which doesnt respond to anything because they’re closed), could I take the actual LTO drive out from the Mercury Pro enclosure and place it into a Magstor enclosure to make a dual LTO or a Netstor <b style=”font-family: inherit; font-size: inherit;”>NS372TB3?
