Data is the goldmine today; whether it’s your data or professional, it doesn’t matter; what matters is how this data is used—the chances of it getting used in an inappropriate or potentially harmful way are much higher than that of the rest.

Therefore its safety and security must be a top priority for anyone who uses any machine, especially a Mac. The file deleted is not deleted and recoverable, and it’s become more obvious if you sell your Mac or want to scrap it without taking any measures to wipe out your data.

Erasing data on Mac:

One way to erase your data from Mac is to delete them securely first. If you are using the older models of Macs having HDD in them, you can securely wipe out the free spaces on your Mac and prevent your data from getting recovered by any third person.

Macs with SSD don’t need wiping of free spaces; that’s what Apple claims; according to them, erasing free space on your Mac is unnecessary because standard data erase it difficult for anyone to recover it.

Secure Erase Free Space:

A disk utility feature adds a layer of privacy and security to free space left after file deletion. The secure erase free space allows you to overwrite the free space that eventually protects or prevents your deleted data from being recovered.

The latest Macs or models with OS X or later versions don’t have a secure erase free space feature in their disk utility because all these models come with SSDs. According to Apple, they don’t need any extra features to protect deleted data. Their standard deletion of the file wipes it out completely from memory.

How to erase a drive using Disk Utility on Apple Silicon Chip Mac:

Suppose you plan to upgrade your Mac or change its ownership by selling it. In that case, it is highly recommended to erase your data before handing it out to someone else and secure your deleted data from getting recovered by any third person.

Disk Utility, among other features, also holds a feature to wipe out your data securely and completely from your hard drive. One important tip is to backup your important files before erasing a disk. For erasing your Mac startup disk, you need to access macOS recovery first. For that, follow the following steps:

  • Restart your Mac, hold power button until you see the startup options window. Select Options, then click Continue.
  • If prompted, select a user, then click Next and enter the password.
  • From the utilities window, select Disk Utility and click Continue.
  • Then use Disk Utility to erase the entire startup disk.

How to free up space:

If you only want to free up space on your Mac rather erasing the data, then freeing up space by removing junk files is much easier to do, and you can do it in two ways:

You can use the optimized storage feature found under Apple > about this Mac > Storage > Manage.

Or you can use the dedicated junk destroyer that may come in third-party software - such as MacClean360.
