Once I have scanned a document to my Mac can I make changes on the scanned document? - Answered by a verified Mac Support Specialist. Is there any way to recover a deleted file from a usb once it has been pulled out. Please give me help to scan a document on to my Mac computer. I have put the document face down in the correct place. The face recognition is a good authentication system which makes your confidential files or folders more secured. Having the face recognition login system with the Windows computer ensures that no one can break into your system without you as there is no chance of stealing your log-in password.
I don't know of any that are touted as 'portable'. Usually they want to install low-level services to monitor activity. I guess if you found one that just ran as an app you could add it to a boot USB, which you can easily make with TechTool ProToGo or Paragon's Hard Disk Manager. Note, Macs don't have optical drives since about 2010, so you might need one of each type, disk/USB & OS to match depending on the age of the Mac. If you have 2 Macs, you could boot the one you wanted to test into Target Disk Mode, though that would potentially expose the other machine to any threat. – Aug 25 '16 at 16:13.
