You’ll want to securely erase that SSD, but it’s a bit tricker than a plain hard disk. The first thing to do is read Apple support article. “ What to do before you sell or give away your Mac. Option 1: Selective erase files or folders on MacBook Air. If you don’t want to erase the entire hard drive, this option is good for you. Just select the files or folders that contain your sensitive data, then click on Erase button, Super Eraser will help you permanently erase.

Depending on the edition, iShredder™ Mac® comes with secure deletion algorithms such as DoD 5220.22-ME, US Air Force (AFSSI-5020), US Army AR380-19, DoD 5220.22-M ECE, BSI/VS-ITR TL-03423, BSI-2011-VS, CSEC ITSG-06, NATO Standard, Gutmann, HMG InfoSec No.5, DoD 5220.22 SSD and others.

Click Erase, then complete these items: Name: Type the name that you want the volume to have after you erase it. Format: Choose APFS or Mac OS Extended (Journaled). Disk Utility shows a compatible format by default. If you see an Erase Volume Group button, the volume you selected is part of a volume group.

Each algorithm has been analyzed by authorities and independent organizations to make sure it does what it says on the tin – data destruction beyond redemption.

Specifically developed by Protectstar™ Inc. in 2007 it runs through fifty erasure routines.
Data will be overwritten for two times with a random value, afterwards with their complements. It includes and the DoD 5220.22-M (E) standard and Peter Gutmann method and random algorithms.

The algorithm from Peter Gutmann was found in 1996 and makes 35 overwrite passes in total.
This algorithm is one of the state-of-the-art methods for data destruction.

In March 2010 the German Federal office for IT Security (BSI) published a new technical BSI Guideline for 'Requirements to overwrite memory media'.
The method is similar to VSITR standard for magnetic storage media.
In total the new algorithm has 8 cycles, which has to be worked through in chronological order. Includes one cycle of verification.

The NATO method is the deletion standard of North Atlantic Treaty Organization (NATO).
It will overwrite the target data area 7 times.
The first six overwrites are with the fixed values (0x00) and (0xff), alternating between passes.
The 7th overwrite is with a random value i.e. 0x00,0xFF,0x00,0xFF,0x00,0xFF and 7th pass with a random value.

The method for high security is based on the January 1995 'National Industrial Security Program Operating Manual'by the Department of Defense (DoD).
In this seven cycle variation (DoD 5220.22-M ECE), data is first overwritten three times with DoD 5220.22-M (E) Standards, then with a specific random value, and finally once again with DoD 5220.22-M (E).

The Royal Canadian Mounted Police Standard RCMP TSSIT OPS-II overwrites data securely with alternating sequences with a total of seven cycles.

The German Federal office for IT Security (BSI) describes in the technical BSI guideline for 'Requirements to overwrite memory media' from July 2010 the modern method BSI-2011.
This clause includes 5 steps, which is implemented in sequential order.

The Advanced Secure Deletion Algorithm developed by Protectstar™ in 2017 includes a pass that encrypts the blocks completely using the 256-bit AES doing a complete verification of written data.
The last pass wipes all data through a random pattern, while high-quality random numbers are generated based on Federal information processing standards (FIPS).

This method is specially developed for SSD (Solid State Drive) and flash memory, based on the U.S.
Department of Defense's standard DoD 5220.22-M E. It will overwrite data four times.

The Canadian CSEC ITSG-06 sanitization method has three cycles and was published in 2006 by Communication Security Establishment Canada (CSEC).

The HMG Infosec Standard No 5 - enhanced level is approved to wipe UK Government Top Secret data and has also been approved by NATO.
The algorithm is a three pass overwriting algorithm: first pass - with zeros (0), second and third passes with its compliment and random values(with last pass verification).

The AFSSI-5020 sanitization method was originally defined in the Air Force System Security Instruction 5020 by the United States Air Force (USAF) in 1996 and may still be today.

This is the US Navy standard NAVSO P-5239-26 for MFM encoded drives.
This deletion method first writes the fixed value (0xffffffff) to the target data area, then the fixed value (0xbfffffff) and then random values.
Finally, the target data area is read to verify the overwrites.

This is the US Navy standard NAVSO P-5239-26 for RLL encoded drives.
This deletion method first writes the fixed value (0xffffffff) to the target data area, then the fixed value (0x27ffffff) and then random values.
Finally, the target data area is read to verify the overwrites.

AR380-19 is the data shredding algorithm specified and published by the U.S. Army.
The algorithm is a three pass overwriting algorithm: first pass - with random bytes, second and third passes with certain bytes and with its compliment (with last pass verification).

The method for low security but for high execution speed is based on the January 1995 'National Industry Security Program Operating Manual' from the DoD (US DoD 5220.22-M).
The variation (DoD 5220.22-M E) offers 3 cycles in which the data are overwritten with first a set value, then its compliment, and then a random value.

The American NCSC-TG-025 standard of the National Computer Security Center (NCSC) securely overwrites existing information on a data medium three times.

The in 2006 released standard is the Special Publication 800-88 from NIST, which is the go-to data erasure standard for organizations in the United States. Its principles can apply to magnetic, flash-based, and other storage technologies, from USB drives to servers.

The Russian data deletion standard GOST R 50739-95 for secure data erasure overwrites the target data are two tome. In the first pass with a zero, and in the second pass with random characters.

ISM 6.2.92 is the Australian government's data sanitization standard.
The method was originally defined in the Information Security Manual (ISM) issued by the Australian Department of Defense: Intelligence & Security.
The ISM 6.2.92 sanitization can not be used to sanitize classified information.

This method is specially developed for SSD (Solid State Drive) and flash memory.
It offers one cycle which data are overwritten by the pattern '0xFF'.

This method for lowest security but for very high execution on speed. It offers only one cycle which data are overwritten with random values.

GDPR-compliant data erasure

With the latest European General Data Protection Regulation (EU GDPR), new requirements for the secure deletion of data have arrived, which applies to all companies.
If sensitive information falls into the wrong hands, this can result in a serious loss of revenue, penalties, or damage to reputation. In addition to the GDPR Art.17 'Right to erasure (‘right to be forgotten’)', please see article: https://gdpr-info.eu/art-17-gdpr/ - data protection laws prescribe a thoroughly documented destruction of data. Personal data is no longer required, for which there is no legal basis for long-term storage, and must be permanently and securely removed from the IT systems.
iShredder™ offers all possibilities for complete protection of sensitive information, and GDPR-compliant data deletion, including detailed erasure reports.

That little silver trash can on your Mac’s desktop represents an invisible Mac trash folder. Technically, items in your trash are still on your Mac, as you can drag them right back out. To delete those items, you simply empty the trash. But are they really gone?

In this post, we’ll talk about the difference between “empty trash”, “empty trash securely”, and how to make sure your deleted files are well and truly gone.

And if you'd like your files to completely annihilate, try a Shredder tool in CleanMyMac X. This tool is absolutely free to use.

The difference between Empty Trash and Secure Empty Trash

When you empty trash in macOS, the files inside aren’t actually erased. The space they occupied is marked by the system as available for overwriting, but the files themselves remain on your drive until they’re overwritten by something else. This means if someone wanted to recover deleted files with special software, they have a chance to succeed, although it’s a tedious process. This is where the secure empty trash feature comes in.

When you empty trash securely, the system writes a series of ones and zeroes over the file you’ve deleted, making it impossible to recover. This feature was an option in OS X until the release of El Capitan, when Apple removed it.

Secure erase is different for SSD and HDD drives
Before 2012, all MacBooks had HDDs (magnetic drives). Today, the industry standard is SDD and all MacBooks are shipped with those. The old way of 'secure erase' doesn't work for solid state drives. But if you need to make sure the files are 100% gone, still there are ways to do it.

How to secure empty Trash on macOS Catalina

1. Force empty trash using Terminal

Before we begin, a note. You can make a mess of things with Apple’s Terminal. It’s crucial to understand the commands and type them without errors. If you start to sweat a bit just reading this, move on. There are alternatives. Otherwise, here we go.

First, you should enable Terminal as a service in the right-click menu.

Click on Apple menu > System Preferences > Keyboard.
Now, choose Services.
Make sure 'New Terminal at Folder' is ticked.

This command allows to apply Terminal commands to a particular folder. In our case, the Terminal will secure erase the entire folder content.

Put your undesired documents in a new folder
Now, right-click this folder to reveal Services.
Choose New Terminal at Folder
Enter the final Terminal command

We've come to the final part. Now we need to tell Terminal which files to secure erase from the folder we've just specified.
Paste in the following command into the Terminal window:

rm -P Archive.zip

But replace Archive.zip with the name of YOUR file and its extension — it's the file inside the folder you want to erase.
Click Enter and wait for magic to happen. The file or archive should now be completely and securely erased. Check your folder to see the file gone.

2. Empty trash securely with CleanMyMac X

Fortunately, you can empty trash securely in a click with CleanMyMac X app by MacPaw. Not only does it empty your desktop trash, but it also cleans up all the other trash bins on your Mac, including those most often overlooked. This program is also notarized by Apple.

Multiple trash bins? Yes! For example, Photos has its very own trash. When you delete an image from Apple’s Photos app, it’s actually moved to the Photos trash. You won’t see it in your desktop trash can. The same goes for Mail, Aperture, external drives and more. Even if you forget about theses bins, CleanMyMac does not. So, let’s take a closer look at how you can empty all the trash bins securely with CleanMyMac X.

Once CleanMyMac is running, click the “Trash Bins” icon on the left hand side, and then hit Scan. CleanMyMac X browses all the trash bins on your drive and in your apps, finds everything that can be securely removed, and shows you a list of what it has found.

After completing a scan, you can browse what’s been found, and easily de-select any file you’d rather keep. For a more detailed view, click Review Files to see what’s been identified in each individual trash bin. If you’d like to inspect a file itself, just hover your cursor over its name and then click the magnifying glass icon to open that item’s enclosing folder.

Finally, we’ve been talking about securely removing files once and for all, so let’s do that with CleanMyMac X.

Even though Secure Empty Trash is no longer a native function in OS X El Capitan, you can still empty your Mac’s trash securely with CleanMyMac X. Try CleanMyMac and be sure the files you delete are really gone.

A free Shredder tool in CleanMyMac X

Secure deletion means replacing the original file with random sets of zeroes and ones. That prevents anyone from recovering the file. That's what digital shredding does. It removes the file and overwrites it afterwards. Such free tool is available in CleanMyMac X.
In CleanMyMac X, choose Shredder tab at the bottom of the sidebar.
Now, select files you want to erase.
Be careful, you can't un-shred an important file.

3. Delete files straightforwardly

Finally, there is a way to delete files immediately, without putting them into Trash first. This is not a secure deletion (doesn't overwrite files) — but rather analogous to emptying the Trash.
1. Highlight a file you'd like to delete.
2. Click File in the top menu.
3. Hold down the Option key.

Immediately, you'll see an option for 'Delete immediately' in the menu.

Use this at your own risk.

Okay. Now you know how to securely erase files on macOS. And, hopefully, your Terminal experience hasn't been too stressful. For easier options, there are many free tools you can use. One of those is CleanMyMac X's Shredder.
