I have a iMac late 2015, El Capitan 10.11.5 and I use SoftRAID for my OWC Raid. The SoftRAID program find the Samsung T3, and list that the SMART status as passed test median life remaining 100%. The Apple disk utility list the drive correctly also with the S.M.A.R.T status: verified.
It seems that the driver for the T3 is a build with debug information. When I run the system profiler the storage and usb status return 'There was an error while gathering this information' - looking in the system log i get the following details.
6/4/16 4:42:29.297 PM System Information[820]: Failed to parse plist output from '/usr/sbin/system_profiler -nospawn -xml SPUSBDataType -detailLevel full', error: Error Domain=NSCocoaErrorDomain Code=3840 "Unexpected character S at line 1" UserInfo={NSDebugDescription=Unexpected character S at line 1, kCFPropertyListOldStyleParsingError=Error Domain=NSCocoaErrorDomain Code=3840 "Unexpected ';' or '=' after key at line 1" UserInfo={NSDebugDescription=Unexpected ';' or '=' after key at line 1}}
However, i have not had issues with the drive that is just awesomely fast.
