Okay it looks as though I have done a stupid thing! OSX: 10.11.6 I have a Lacie HD that I am using as Time Machine back up. I decided to delete some very old back ups that I no longer needed and dragged them direct to my desk top trash. I now cannot delete these files from my trash. I have researched and some recommend going to Utilities > Terminal > csrutil disable to disable the SIP and then delete from the trash. Even disabling the SIP I cannot delete the folders from my trash. I have also looked to 'put back' the files to the original external HD but some files have this right click option, but most don't. When I do chose the put back option it dumps the folder on my desk top and not back to the HD. Any suggestions how I delete all these many folders from my trash?
