Not yet running macOS 10.12 however under OS X 10.8.5 the man page for srm in the NOTES section states: Development and discussion of srm is carried out at, which is also accessible via. Now you'd have to download the source code and compile it for yourself. This would require Command Line Tools for Xcode be installed. Not sure if still applicable under macOS 10.12 however, see for details. Or in Terminal use the following command: xcode-select -install I downloaded the latest source code and it compiled without errors under OS X 10.8.5, although that doesn't mean it will under macOS 10.12 but it's probably the only choice you've got if srm has been removed. That said, I probably would only srm on rotational HDD's not SSD's. From this comment: can you come up with a better idea or safely removing files from SSD on newer macs?
– Niktin Roman There's no need for srm; provided that TRIM is enabled on your machine 1 TRIM support handles this for you. When you delete a file from your drive, the OS will mark the file space as 'not in use' - this applies to any drive. On an SSD, unlike a HDD, a TRIM command is sent to wipe any data in that marked space. This allows your SSD to be able to write data to that marked space as if it was brand new and never used, and skip the traditional deletion process.
If you are looking for more security, turn on. Per: Note: With an SSD drive, Secure Erase and Erasing Free Space are not available in Disk Utility. These options are not needed for an SSD drive because a standard erase makes it difficult to recover data from an SSD. For more security, consider turning on FileVault encryption when you start using your SSD drive. I also advise against using srm because it issues more and unnecessary write operations to the SSD, thus shortening it's lifespan. From the: srm removes each specified file by overwriting, renaming, and truncating it before unlinking 1 TRIM comes enabled by default if you your Mac came with an SSD preinstalled. If you added an SSD after the fact, then you must enable TRIM by issuing the command sudo trimforce enable in Terminal.

To securely delete a file/folder on MacOS Sierra without external utilities use rm with the -P switch: ## delete a single file rm -Pv wikileak1.txt ## delete a folder recursively rm -Pvrf /.wikileaks From the: -P Overwrite regular files before deleting them. Files are overwritten three times, first with the byte pattern 0xff, then 0x00, and then 0xff again, before they are deleted.v increase verbosity NOTE: In case you installed from homebrew with the default names, e.g. Brew install coreutils -default-names, then, depending on how you configured your PATH, the GNU version of rm could shadow the Mac version at /bin/rm and it won't accept the -P option. Use which -a rm to double-check.
