I wish to have the option of Securely Deleting the items in the Trash Bin on my MacBook Pro (running OS BigSur 11.5.2).
However all the answers I can see state that there is an option to do just that in the Advanced drop down menu of Finder. However, that isn't the case on my screen!
Can someone please tell me how I can go about selecting the option to perform a Secure 7 Pass Delete of my Trash Bin?
Thank you
What year MacBook pro?
Most recent models have an SSD boot drive. When you Empty Trash on those, with TRIM active, the files GONE. Every 'Empty Trash' is a secure delete.
Within seconds, the drive controller erases the blocks where those files used to be, in preparation for new data. then the block numbers are randomized. There is no lurking data residue. NOTHING can be recovered by any means.
Secure erase was removed because it caused excessive SSD wear, but provided no additional benefit.

Thank you Grant,
My MacBook Pro is a 2019 model, so I presume it has the SSD Boot Drive you mentioned. How can I check as to whether TRIM is active, so that I can ensure I am Securely Deleting my Trash Bin?
Any further help you can give me would be gratefully received.
Thank you once again
If you have the standard Apple SSD, TRIM is active by default, and can not be turned off.
On that system, every 'Empty Trash" is a secure delete.
