Get all drives in MAC ?

and what kind of drives i have in MAC?

Your question is not clear. Unix has a unified file system. Drives are mounted into file system, so you just use directory services. macOS supports both auto mounts and hard mounts.

if you programmatically want device info, then you would use IOKit sdk.

https://developer.apple.com/library/archive/documentation/DeviceDrivers/Conceptual/IOKitFundamentals/Introduction/Introduction.html

note: as Maui build catalyst apps, you have limited permissions.

Can you please supply code sniped how to get programmatically the device info,

use IOKit sdk?

what info do you want? the standard unix approach would be to spawn (fork) the ioreg or system_profiler utility and parse the output:

http://www.manpagez.com/man/8/ioreg/ https://ss64.com/mac/system_profiler.html

example - usb device info:

% ioreg -p IOUSB
+-o Root  <class IORegistryEntry, id 0x100000100, retain 30>
  +-o AppleT8103USBXHCI@00000000  <class AppleT8103USBXHCI, id 0x1000004ed, registered, matched, active, busy 0 (13 ms), retain 39>
  +-o AppleT8103USBXHCI@01000000  <class AppleT8103USBXHCI, id 0x10000037f, registered, matched, active, busy 0 (2 ms), retain 39>
  +-o AppleUSBXHCITR@02000000  <class AppleUSBXHCITR, id 0x1000a7757, registered, matched, active, busy 0 (1226 ms), retain 375>
    +-o USB2 Hub@02100000  <class IOUSBHostDevice, id 0x1000a7762, registered, matched, active, busy 0 (1215 ms), retain 36>
    | +-o Studio Display@02140000  <class IOUSBHostDevice, id 0x1000a777f, registered, matched, active, busy 0 (882 ms), retain 159>
    | +-o USB Flash Disk  @02130000  <class IOUSBHostDevice, id 0x1000dc51b, registered, matched, active, busy 0 (118 ms), retain 29>
    +-o USB3 Gen2 Hub@02300000  <class IOUSBHostDevice, id 0x1000a7771, registered, matched, active, busy 0 (256 ms), retain 33>
      +-o INIC-3609       @02310000  <class IOUSBHostDevice, id 0x1000a778c, registered, matched, active, busy 0 (251 ms), retain 45>

example - list USB device name only:

% ioreg -p IOUSB -w0 | sed 's/[^o]*o //; s/@.*$//' | grep -v '^Root.*'
AppleT8103USBXHCI
AppleT8103USBXHCI
AppleUSBXHCITR
USB2 Hub
Studio Display
USB Flash Disk  
USB3 Gen2 Hub
INIC-3609       

example usb profile in json:

% system_profiler SPUSBDataType -json

Hi,

There is no code in C# to get all the drives and volumes?

In windows i did :

DriveInfo[] drives = DriveInfo.GetDrives();
