The reason you are worried about that is your startup drive is not secured, which means that file you deleted is just one of many that someone could read. Enable full-disk encryption on the startup disk by enabling System Preferences > Security > FileVault, then a would-be thief won't be able to boot from or access the encrypted data on the startup disk - even if they remove it from the computer and put it into another computer or enclosure. Your data is safely encrypted. Set a firmware password on your Mac so the computer will refuse to start up from any internal or external storage device other than the startup disk you have selected in the System Preferences > Startup Disk preference pane. Enable Find My Mac in System Preferences > iCloud > Find My Mac, then if your Mac is lost or stolen, you'll be able to remotely lock it, track its physical location, display a custom message on it, play an alarm sound on it, and even erase the contents of the startup drive remotely from any iOS device or any computer with a web browser. With that setup if you delete a file on the startup disk, you don’t have to take any further action, because all of your data is encrypted. -- E-mail sent to this address may be devoured by my ravenous SPAM filter.
