I am trying to get disk information from a sandboxed macOS app bundle. system_profiler SPSerialATADataType SPNVMeDataType will run in both sandboxed and non-sandboxed. However their outputs are slightly different. I am wondering how from within the sandbox I am able to get the information similar to the non-sandboxed output. Specifically I am looking at SMART status and size. Is there and entitlement I can add that specifies storage devices? What specifically is being changed being inside a sandbox that is changing the output of this command?

  • You'd be probably better off using DiskArbitration Framework https://developer.apple.com/library/archive/documentation/DriversKernelHardware/Conceptual/DiskArbitrationProgGuide/ManipulatingDisks/ManipulatingDisks.html#//apple_ref/doc/uid/TP40009310-CH3-SW7 – mahal tertin Apr 02 '20 at 09:00
  • That framework seems to lack support for S.M.A.R.T status' and appears to be severely limited when inside a sandboxed app. There is a ```App Sandbox Note``` describing the limits on one of the related pages. – AnotherUser Apr 02 '20 at 13:26
