Hi,
I just got my Mac Studio and I have read a bunch of the previous posts and tried the solutions as suggested. I have found SoftRAID.kext in quarantine a number of times and removed it. I have uninstalled the driver and uninstalled the app and reinstalled with csrutil disable but my ThunderBay 4 still won't mount. If I try to mount it from Softraid, it takes about 30-45 mins and then will mount in Read Only mode. I get a message from MacOS disk utility popup and say the drive is unrepairable.
This is what I get when I run: sudo kextstat -b com.softraid.driver.SoftRAID
/usr/bin/kmutil showloaded --bundle-identifier com.softraid.driver.SoftRAID
No variant specified, falling back to release
Index Refs Address Size Wired Name (Version) UUID
Thanks!
Do not disable SIP on M1 in particular. SIP is not necessary to disable.
reenable with csrutil enable.
I sent you something try off line. Let me know if it worked.
