HighPoint finally acknowledged Mac OS 12 on their Downloads website, and they have updated the driver to v1.1.29. I have not tried it yet, since, for some reason, I suddenly can't get v1.1.26 to work on my clone drive, even though it's a clone of my boot drive where v1.1.26 works fine. Every time I boot the clone, I get a message about a third party extension conflict, and the HP driver gets disabled. Weird.
 
I finally tried HP driver v1.1.29 on my 7,1 Mac Pro. Works fine with Mac OS 12.1. Still can't get it to work on my clone drive - it still has an extension conflict disabling the driver. Odd since this drive is cloned from the boot drive with no such conflict. Still trying to figure this out...
 
Mine is way older... 11300B20
I've been playing with getting the same drive to work all weekend with nothing but issues. 2019 Mac Pro will usually restart numerous times before finally booting. Micron 9300 Pro FW: 11300B20 (according to label). I've tried two different PCIE adapters, so quite sure the issue is the drive. Is there any way to update the firmware with a Mac? Any ideas what the issue could be? 2019 Mac Pro has a fresh install on the 256GB Apple drive. Have tried with both Catalina, Monterey, all the latest updates, etc. When the Mac Pro does finally boot after a number of attempts with the 9300 installed, a message appears regarding "Panic Medic Boot". Only thing I can think of is there is something related to the FW on the 9300 that the Mac Pro doesn't like.
 
I wanted to post my experiences with putting the Micron 9300 Pro drives in a Mac Pro 5,1 since it looks like this discussion is only about 7,1.

Using both the Startech card and the Sonnet dual card, the 7.68TB model works fine, and gives around 1500MB/s read and write (AJA and Blackmagic). Except, oddly, if I put it in the x16 slot using the Startech card, I only get half speed. Just that slot. And the Sonnet in that slot is fine. Seems like it’s running PCIe 1 speeds. No trouble; use another slot.

Then the weird(er) thing. I decided to get the 15.36TB model. Installed, turned the Mac on, and... nothing. No chime, no screen. Doesn’t matter which adapter card, doesn’t matter which slot, doesn’t matter which 5,1 (I have two). Put the smaller SSD in and it chimes and boots. So I gave up and am going to use the drives in a Sonnet PCIe Thunderbolt chassis hooked to an M1 Mini. That works fine. I did not test on a Mac Pro 7,1.

Long story short: Micron 9300 Pro 15.36TB prevents Mac Pro 5,1 from booting.
Would the 5,1 restart with the 15.36TB? Wondering if it was related to firmware. Can't get a 7.68TB working with my 7,1 without restarting numerous times.

I'm someone at a loss why youre having difficulty. what PCI card are you using to control the drive?

The biggest hangup is you have to change security settings via the T2 security boot utility, lowering them to allow for booting from external drives. After that, I had no issues.

Can you see and format the drive when you boot off the 256GB apple drive (I have the same 256 apple drive).

Yep, it's strange. I've tried the Sonnet U.2 Dual Fusion and the Startech adapters. Same behavior. When the Mac Pro boots, I can see the drive, I can format the drive, etc. I even successfully installed Monterey on it although it took a few hours with multiple restarts. However, regardless of what drive I boot with (Micron or Apple), it restarts multiple times before a successful boot. I changed security settings before installing the Micron drive. Guessing there's a kernel text on the drive that Mac doesn't like? No issues booting when the drive is not installed.

Also, out of curiosity, are you still having to change sleep settings in order to use the Micron drive? Thanks.

I guess that’s the difference. I’m using a different Pcie controller card. The high point 7120.

Sleep works fine on the machine.
 
Anyone tried HP driver v1.1.29 with Ventura beta? It's coming out Monday, and that is still the latest driver I find on their web site.
 
I updated my 2019 7.1 Mac to Mac OS v 13 (Ventura) and now it does not even see the three NVMe drives in my HP SSD7103. Before, if there was a problem with the driver, on booting, it would ask if I wanted to initialize the three drives in my RAID, but now it does not even ask me if I want to do that. I just downloaded the latest driver from HP, and it is still v1.1.29. I tried re-installing the driver, and it didn't even ask me to grant permission in Privacy & Security. I checked, and there is still a check next to the HP driver, but the drives no longer show up.

I am in the same situation. I'm reverting back to 12.1. Did you contact Highpoint yet?
 
Na not much point in contacting them, sooner or later they will update but it would put us in the same boat every update.

Have 4 1TB cards in it, just did a raid 10 with them Mirrored each pair and then raid 0 on the pair of them, yeah I loose some space but I don't have to worry about a single card failure, or the driver breaking with each update.
 
FYI: Highpoint has a beta driver with Ventura support if you contact them. I haven't tried it as I am rolled back to 12.1. Driver is 1.1.30.
 
There aren't many places to talk about U.2 SSDs in Macs, so please forgive me if I resurrect this old thread.

Short Version: Micron 7450 U.2 do not work. At least up to and including macOS Ventura 13.0.1.


Ignore any listing, including Sonnet's Fusion Dual U.2 official compatibility list. It's the reason I decided to get two Micron 7450 to and a Fusion Dual U.2, especially as old drives such as the Micron 9300 are hard to impossible to get today.

Well, the 7450's don't work even in current macOS 13.0.1. The SSDs are recognised as PCIe devices in System Utility (and ioreg), but listed with Driver Installed=no. Booting the same Machine into Bootcamp and Windows 10 Pro properly recognises the drives and it can use them.

I even asked Sonnet support about the 7450 being listed in their drive compatibility document but not working.
Let me quote one sentence from their reply to me:
We tested the Micron 9300s with macOS, and those worked, so we assumend that the 7450s would as well, but that appears not to be the case.

Have been using a 9300 Pro as a boot drive for several months now. Love it. Have also had success with the 9200.

Sorry, I’m still using the 9300 and the high point 7120. They both seem solid in 13.0.1

Returned the two Micron 7450 drives and the Kioxio CD6-R I ordered for testing arrived today and it's recognised by macOS and read/write works. Waiting for the 2nd drive to arrive before taking it into production.

Update: while I tested the Fusion Dual U.2 with 2x CD6-R in an external case (Sonnet Echo) and they worked, that changed when I installed them in my MacPro today. Turning the MP on the status LED lights up but nothing after that. No startup chime, no display output, nothing. After some testing it seems that happens when they're in the external Thunderbolt PCI case during startup as well. Once the MP has booted they work fine though.

Unfortunately Kioxia doesn't offer firmware updates on their website. Send a request to Kioxia to find out if there's a newer version than 0105 that my drives got.

Oh, and of course Sonnet lists the CD6-R as macOS compatible on their website. Just like with the Micron 7450 - which is still listed as compatible 10 days after me telling Sonnet's Support people that it doesn't work with macOS at all.
 
I have interesting situation with this model: Micron 9300 Pro 3840GB (U.2 NVMe):

When inserted in Mac Pro 2010/2012, machine doesn't chime. Tried in slots: 2,3 and 4.

Interestingly, Mac Pro 2.1 chimes with this adapter and El Capitan recogniose it as NVMe Express Controller but of course drive is not detected because it needs High Sierra.

Any thoughts why 5.1s doesn't even chime with it ?
