OS Monterey 12.0.1 - SanDisks Have Stopped Working

Since upgrading my MacBook Pro to OS 12.0.1 Monterey my SanDisk USB drives aren't working. When I try to access using the installed SanDiskSecureAccessV3_mac application I get "This application only runs on a SanDisk flash drive." I've reinstalled app and nothing changes. Can't access. All of the drives worked fine before the upgrade.


What's up?

Question marked as Apple recommended

Can you try the drives on another computer?

I would contact SanDisk, maybe an updated app is required for Monterey.

It's hard to believe that Apple or SadDisk has not addressed this problem! I told him about it the day after the software update came out! The only thing that saved me is that I use my old computer that is not updated, I purchased Seagate back up plus for Mac- you can make that secure and you can say goodbye to SandDisk what's your move all your files over! At least I have secure and accessible files by doing this. I don't think Apple or SanDisk care anymore about anyone who fights faster problems.

Looking up at Sea gate there Secure software it's very easy to use and you can make it secure!

I started another thread before I was pointed over to this topic about the problem I was having with my late model Intel Mac running Monterey 12.0.1, and I was able to confirm the problem is Monterey and not limited to the M1 architecture:


https://discussions.apple.com/thread/253412693


Here is the last post from that thread confirming the steps that I took to determine why the Monterey Mac was unable to get past the erasing step in disk utility of formatting the drive:


Update: I took it to Apple support and very helpful senior advisor looked over with a screen share and we verify that there was no specific finding in activity monitor or console logs that acknowledged or suggested any kind of hang process; we took it through Recovery Mode version of Disk Utility ("to get the OS out of the way") and had the same thing, where it get stopped at the erasing stage, even with setting it up without encryption.


So I fired up the 2012 Catalina Mac, and it happily formatted the drive to the point where it was mounting in two minutes or less with macOS journaled or AFPS options. Then I took the formatted drive with AFPS, not encrypted, plugged it into the 2020 MacBook Pro running Monterey 12.0.1, and it happily mounted the drive and Time Machine is now backing it up and encrypting as it goes.


This experience demonstrates that the SanDisk the problem is not based in M1 architecture, because this is a very recent Intel Mac (purchased October or November 2020) running Monterey. And this same recent Intel Mac had no problem formatting an identical twin drive for Time Machine before the update from Big Sur (which came on the computer) to Monterey.

Hello Guys , any update here . is there an update for san disk secure access for Monterey ?

I bought the san disk on Sunday , I have put all my data on it , and checked the password app secure access , it was working on big sur but I did not put password .

On Monday I updated to Monterey , the drive is working , thanks god I did not put password otherwise I would have lose the access to my data in one day .

I feel I should have taken the Samsung T7 touch as it secured by touch and that’s easier.

But now I need to secure my Sandisk. so any update please .

I contacted San disk and they replied that the problem is due to incompatibility of the secure access software with the new macOS Monterey and they are working on the fix.


currently they have released the private access which replaces the secure access.

I have tried it and seems to work just fine. it takeover the previous secure access files. try it through

I have downloaded the fixes for Mac and Windows I am running Monterey with Parallels for Windows 10.I have tried on both platforms and I get the same error message " This application only runs on a San disk flash drive" The SanDisk is inserted in the usb slotted has been opened. Can anyone tell me what I am doing wrong?
