A good way to separate your data is to partition your Mac hard drive. A partition splits your storage into two spaces, like putting a trunk divider in your car. The most common use case is to install a second operating system on the same computer. In college, I had a separate partition so I could boot into Ubuntu, and a third partition with Windows. With today’s Macs running Apple silicon, there’s no easy way to natively install Windows or Linux… yet.

But you’re probably here so you can install the beta version of macOS 13. The developer beta is anticipated for release the first week of June at WWDC22, Apple’s annual developer conference. The smart way to install it — especially with the developer betas, which can be notoriously rocky — is to use a separate partition.

The Mac comes with a very handy tool to partition your hard drive for free. Read on to partition your hard drive with Disk Utility.

Secure-erasing your Mac’s disks is no longer secure, Apple says

In the olden days, when you wanted to replace your hard drive with a bigger one, you’d run a “secure erase” on it to completely remove any personal data. This would write zeros to the entire disk, overwriting anything already there.

But now, thanks to advances in storage tech, this no longer does the trick. (Not that you can change your own Mac SSDs now anyway.) The new secure-erase, says Apple, is to just encrypt your disk.

Apple’s latest update for the Mac finally arrived today in the form of macOS High Sierra, bringing a host of improvements to Mac users.

How To Repair & Verify Your Hard Drive From The Command Line [OS X Tips]

OS X offers a very nice graphical user interface to verify and repair your hard drive, located in the Utilities folder. It’s called Disk Utility, and you can use it as the first line of defense when weird disk-related things happen to your Mac’s hard drive.

If, however, you want to dig in a bit deeper, or you’re already running Terminal a lot and don’t want to launch a separate app, you can use the following commands to both verify (check for problems) and repair any problems that you might find when verifying.

Deep Clean Your Mac’s System With Detox My Mac [Sponsored Post]

This post is brought to you by Detox My Mac.

Prudent Mac users often “clean” their machines to keep them running in tip-top shape. Those in the know repair permissions with Disk Utility, empty caches, delete unused applications and transfer large media files onto external drives on a regular basis so as to clear up space and optimize running speeds. But while all these actions are sensible routine maintenance, they probably won’t make much difference to a heavily used machine running loads of applications whose performance becomes noticeably compromised. Such systems don’t need just a clean but a detox. Detox My Mac selects, scans and deep-cleans your Mac’s system for a thorough detox.

Detox My Mac does not simply offer what the regular OS X disk utilities do but much, much more.

Many of us pass our Macs and some external devices on to others when we upgrade. Family and friends may get our hand-me-downs, but quite frequently we’ll sell an old Mac, printer, or external drive on eBay or some other venue. Regardless of where our computers and related technology end up when we outgrow them, it’s important to make sure we scrub any personal data from them.

The importance of securely erasing personal and/or business data from hardware that is being passed on, sold, or even recycled was highlighted in a recent study by Britain’s Information Commissioner’s Office, which discovered that half of all used hard drives contained information from their previous owners.
