Lacie RAID Manager extensions are being blocked

Hey Todd, great post.

My 5Big LaCie (5 x 4TB) would not work on my M1 MacMini back in October 2020-same issue drivers/Kext's/not compatible kext's ... and all that. After 6 frustrating months with LaCie support, I converted it to a JBOD-which wiped it clean and installed OWC's Softraid; then re-loaded from backups - and I have used this configuration/software since then.

I am now planning to convert it from 5x4TB to 5x8TB Ironwolf NAS drives and since I will have to start fresh, again I was wondering if I might go back to using the LaCie to manage the RAID.

1. Any thoughts on this? I can certainly follow your procedure as I have been around that a few times. Now am running on an M1 Studio Ultra, Sonoma 14.3
2. Also, what kind of performance are you getting on BlackMagic for R/W and how full is your raid.
3. Can you confirm which LaCie utility you are running???? 2.9.4....Back in 2020-2021 they had still not updated the firmware in the 5Big to be optimal with Apple Silicon and while it would finally run in 2021, it was running at USB-2 speeds and they just could not get their act together on this. So, I am interested if the new firmware combinations finally get the speed back to where it should be in the 400MB/s range.

Thanks for your input

I had this exact problem on an M2 Mac Studio running Ventura 13.6.1. Following the advice of LaCie and others just created an endless loop of restarting with no results.

But I got it to work! Here's how:

Boot the Mac in Safe Mode. Then install LaCie Raid Manager. After doing this, you should see the "Seagate LLC" extension listed as "On" in the Login Items. After that, restart. You will get the "System Extension Blocked" popup. Go to System Preferences and click "Allow" for the Seagate extension. When given the option to "Restart" or "Not Now", choose "Not Now". The computer will pause for several seconds before the popup goes away. Then manually restart the Mac.

After I did this, the Mac chimed TWICE. This was a good sign that the Seagate Extension was allowed. After that, my LaCie 5Big 16TB Raid was recognized!

I've just received my refurbished Mac Studio. Was SO excited to get my workflow times down. Gone through a lot of today trying to set things up and now I'm facing this same issue that so many others are and I can't access my DROBO. This is a HUGE problem for me if I can't access it and will cost my business money. Apple needs to fix this issue or at least provide clarification or a work around ASAP. This is so poor that this has been happening for so long. How are people supposed to access their data? Crazy. Lift your game Apple.

JC,

I'm using Lacie Raid Manager 2.9.4.

I'm still on MacOS Ventura. From my understanding, updating to Sonoma might jeopardize the ability for the Lacie Raid to connect, so I'm stuck on this OS for now.

I have not done any speed/performance testing of the Lacie drives, as I use them for one specific freelance project only, which is a 1080p show. I haven't had any performance issues, as it seems to run just like it did on my Intel iMac (before it died).

But if you are already on Sonoma, I'm not sure Lacie Raid Manager will work.

You must reduce startup security to install legacy kernel extensions. Maybe the ones that don’t work haven’t been modernized.

I have the same issue with Mac Studio M1 ultra and Lacie 2big raid drives. After installing raid manager it wants to rebuild the cache, but this does not work, it goes into a loop of asking to rebuild cache every startup now unless I change the security setting back to normal. I've dealt with Lacie, trying to get this resolved with no luck. It works on my MacBook Air m1 with Ventura 13.01 but does not work with my Mac Studio with Ventura 13.4

I do not get any "allow" prompts for the marvel seagate semiconductor as I should be getting. I also have a Drobo 5d3 which will not work with Ventura 13.4 on my Mac Studio.

I have a new MacBook pro M2 with Ventura 13.4 and have been trying with no success to install LaCie Raid Manager V2.9.4. Like others posting here I have followed all the instructions on the LaCie support pages. I keep getting sent around in loops to change security and privacy settings and to allow extensions from Marvel, while no such extensions are shown, and to restart. - Only to be shown an error message, regarding, you guessed it.

Basically, I am convinced after several attempts that this instal simply doesn't work, and if I want to monitor my raid drives on my macbook pro, I will have to purchase a raid system from some other vendor. Can you please advise (and please, don't just repeat the previous answers.

I have the same problem on my MacBook Pro 16 inch M2 Max macOS 13.4.1.

I have a LaCie Big 6 RAID and am trying to install LaCie RAID Manager so I can connect the RAID to my MacBook. As previously described, after enabling kernel extensions I end up in a loop where the os states (after restarting) "System Extension Error - An error occurred with your system extensions during startup and they need to be rebuilt before they can be used. Go to Privacy & Security System Setting to re-enable them." Doing so requires a restart which then displays the same error message. Loop-de-loop.

It is crazy. I cannot update my MacBook Air software otherwise will not be able to connect to my Drobo. My guess is we won’t see a fix until the new OS is out, hopefully they fix it in that update at the minimum.

I think you will have to reinstall the extensions to make it ask to allow (if you haven’t tried that already).

I have the same issue and have tried everything I can think of - Macbook Pro M1 Pro with Ventura 13.4.1. I'll log a ticket with Lacie to see if they know anything as well.
