So it is better to permanently and säkert radera filer på Mac if you are planning to sell it to someone else. And before you put it up for sale, be sure to completely remove all the traces of files inside the device.

Part 1. How Do You Securely Delete Files on Mac?
When you delete files Mac and other iOS devices such as iPhone, the information stays hidden inside the hard drive until the data is overwritten. Meaning, they are not completely gone. These data can even be taken against you in case it can be recovered. This means, your personal information is susceptible to identity theft.

Så är det ett sätt att säkert radera filer på Mac forever? Don’t worry; we’ll give you more options on how to säkert radera filer på Mac that no one can still recover, ever!
1. Secure Empty Trash on Mac
This is the basic way to delete the files from Mac. You can do this on a regular or weekly basis to also speed-up Mac’s performance.
- On the keyboard, hold down the ‘
Control’ key. - Click on the ‘Trash’ icon.
- Tryck "
Command” on OS X Yosemite/higher. You can press “Control"Eller"Option" istället. - Klicka på "Säkert tomt papperskorgen".
Detta garanterar dock inte att filerna är borta för alltid. Säkert kommer det att finnas spår av koderna som fortfarande kan användas för att hämta informationen.
Securely Delete Files on El Capitan and Higher:
För det senaste Mac OS verkade det som att papperskorgen togs bort eller ännu hellre "doldes". Följ dessa steg om hur du startar papperskorgen och tar bort viktiga filer.
- Open Launch Pad
- Öppna Annan mapp
- Hitta och klicka på Terminal
- Skriv in
srm –v(add space after the v, srm means ‘secure remove’) - Dra och släpp filen/filerna du vill ta bort

Kom ihåg det "fragmentering" means that the files will be overwritten using random code so that if in case it is recovered then the original files will not be decoded.
2. Securely Delete Files on Mac with Terminal
In earlier macOS versions, the srm command allowed secure file deletion in Terminal. With macOS Sierra, Apple removed this feature, but you can still securely delete files using the rm kommando.
First, configure some settings:
- Open System Settings från Apple-menyn.
- Navigate to Keyboard inställningar.
- Under Keyboard Shortcuts, Gå till Tjänsteroch sedan Filer och mappar.
- Möjliggöra New Terminal at Folder och New Terminal Tab at Folder.
Next, locate the file in Finder:
- Högerklicka på mappen containing the file.
- Välja Services > New Terminal at Folder.
In the Terminal window:
- Typ
rm -P filename.ext, byter utfilename.extwith your file’s name and extension. - Klicka Retur för att utföra kommandot.
3. Securely Delete Files via Disk Image
Disk images (.dmg) are versatile for packing and sharing files on macOS. You can create and encrypt them using Disk Utility, turning them into secure vaults for sensitive data. To securely delete files using a disk image:
- Öppna Disk Utility.
- Go to File > New Image > Blank Image.
- Name your image, choose size, and select 128-bit AES encryption. Set a password.
- Copy files to the encrypted disk image.
- Eject the disk image to lock it.
- Move the .dmg file to Trash and empty it to securely delete.
4. Securely Delete Files Using TRIM
Many modern Macs are equipped with SSDs (Solid State Drives) rather than traditional HDDs (Hard Disk Drives). Secure file deletion is more challenging on SSDs, but achievable with TRIM.
TRIM is a tool that automatically clears data in designated "not in use" spaces, allowing new data to overwrite these spaces. While HDDs lack this feature, you can enable TRIM on SSDs using the trimforce command in Terminal.
Steps to Enable TRIM:
- Öppna Terminal.
- Typ:
sudo trimforce enable - Confirm the prompts by typing
yoch trycka påEnter.
Obs: Back up your files with Time Machine before proceeding, as Apple advises caution when using TRIM.

I tried erasing my MacBook Air's HD, following the steps of "Securely Delete Files on El Capitan and Higher" in your article. But I didn't see any options for security. Why?
iMyMac2018-11-12 09:35:19
Apple's removed the secure erase functionality on SSD-based systems like your MacBook starting with the version of Disk Utility included with El Capitan onward, so you're not missing anything - the option isn't there.
