What I want to do is Format my SSD disk of my Mac Book Pro (2019), but I want to do it in a VERY safe way. So that there is no trace of the deleted files and nobody can access them anymore.

That's why I think the best option is to look for a software that formats the disk doing a lot of reading and writing.

I can't find good and reliable software that does that on a Mac. Is there one?

Writing multiple zeros on an SSD does nothing to improve the secure elimination of the data, and significantly reduces the life of the drive.

If you want to make sure that your files are safe: encrypt the drive.

  • Okey.. But what method improve te secure elimination of the data without encrypting the drive? Because I want to delete the file for ever.. – Pedro Gimenez Jul 01 '20 at 17:46
  • Just delete it. Without encryption, that's as good as you can get. – benwiggy Jul 01 '20 at 17:51
  • Oh okey. I'm going to do that, but I'm not 100% convinced. Thanks anyway – Pedro Gimenez Jul 01 '20 at 17:56
  • you could do a lot of reading and writing after you remove the file. Try downloading a very big file. Maybe several copies. After a week or so of use get a data recovery app, one with a free trial, and see if you can recover your file. if you can't then its been written over probably. – Natsfan Jul 31 '20 at 19:42
