Delete Personal Information Properly When Selling Your Computer

This seems like a no-brainer when it comes to selling your computer, whether it be a PC or a Mac. No one wants any of their personal information compromised and fall into the hands of the wrong person.

But according to Kim Komando, a blogger named Josh Frantz spent roughly around $600 on different used devices for security research. What he found was absolutely startling.

“Frantz posted what he discovered on his rapid7 blog — and it was shocking! Of the 85 devices he bought, only two were correctly wiped. Most of the devices still had tons of information on them.

With help from a script he wrote, Frantz found 214,019 images, 148,903 emails and 3,406 documents. From all that, he was able to see email addresses, dates of birth, Social Security numbers and credit card numbers.”

If you are ready to sell any device you have, make sure you use apps, such as Eraser, or Permanent Eraser to delete any and all information that could easily be stolen. You can also look up apps in the App Store to give you options of which disk eraser works best for you.

These devices aren’t limited to just computers. Phones, printers, tablets and other electronic devices acquire certain information that you would not want leaked. Take the appropriate steps to remove the goods, so the goods don’t become tainted when you sell your device.

Clearing the Clipboard on your Mac

When you use your Mac, one of the numerous apps that runs in the background is the Clipboard. This is a very handy application when it comes to copy/paste. When you copy anything, macOS just remembers it and pastes it to your clipboard.

Thankfully, it only copies one thing at a time. Once you copy something else, the previous is erased immediately.

[T]he native clipboard application on Mac doesn’t allow you to keep multiple text copies in your memory at once. It only opens the last one, overwriting anything you might have copied earlier. Although managing a single entry, it can be difficult for some people to come to terms with the idea of a clipboard storing your search phrases.

It uses RAM, which may slow down your surfing performance on your Mac. Clearing the Clipboard frees up memory and protects personal or sensitive data.

The Quickest Eraser

While there are a handful of ways to clear the Clipboard by using commands, the easiest is simply restarting your Mac. Head to the top left of your screen and click on the Apple icon.

Scroll down and select “Restart” on the drop down menu. Make sure to save anything you were working on before restarting.

How to Use Dictate on a Mac

Dictation, Apple’s fully featured accessibility tool, is simple to use. It also does a good job of interpreting your voice. And not everyone enjoys typing. Fortunately, Apple’s software allows you to say what you want to type instead of typing it.

“Do you want to enable dictation?”

To quickly enable Dictation on your Mac, head over to your System Preferences. Next, click Keyboard. Once there, click on the Dictation tab. You will be able to turn it on and select your language and a shortcut.

After you’ve enabled Dictation, begin speaking what you want to put in to see it appear on your screen. This also implies that you must dictate punctuation. Apple recommends dictating in small intervals of 40 seconds or less. You can talk far more quickly than your Mac can receive.

To stop dictating you can either click your shortcut button, click done under the microphone, or simply click return.

While your Mac is analyzing your dictated words, they show underlined. After you have finished dictating, the reformat themselves, as well as any words that your Mac has queried.

Things you need to know about Dictation

Dictation connects with Apple servers in order to transform your speech to text. As a result, it is never totally private. Dictation files can be saved and reviewed by Apple. They do this to enhance dictation, but you can turn it off in Security & Privacy of System Settings.

To utilize Dictation on a MacBook, you must have an active Internet connection. Apple uses linguistic data to analyze your speech on its servers. You will be unable to utilize Dictation if you do not have an internet connection.

Hope this helps make work or school a bit easier!

How to Know What OS Your Mac is Utilizing

While this may seem like a simple, unneeded bit of information, knowing what operating system your Mac computer is using can help when you’re needing certain aspects of features – which often requires a certain version. If you have the wrong version, it may not work for you.

The OS software controls your entire computer, including memory and hardware devices like printers and drivers. It works with the CPU (central processing unit) to make sure your computer runs the best it can. The software and the hardware go hand-in-hand.

Here’s how to find out what OS your Mac uses:

  1. Go to the Apple Menu Icon
  2. Click on “About This Mac”

From there, you’ll see the overview of information, including the name and version. There are a plethora of names, including Catalina, Mojave, and High Sierra.

In order to get the most out of your Mac, make sure that your operating system is up to date with the newest version. This will allow security to be on top of its game. Simply click on the Software Update button and follow the prompts.

Apple Event Highlight: M1

Today, Apple announced new iMacs and iPads set to be released by mid-May during their Apple Event. These new devices will incorporate Apple’s brand new M1 chip, which will replace Intel’s chip.

Before this, Apple had to involve several chips to do what the new M1 chip can do. This includes memory, security, and processing. But with this new innovative design, the M1 is all around powerful. The graph below, from Apple’s website, shows a 2x faster CPU performance in the M1. Also, the M1 only uses 25% performance of what a PC normally uses. This is mind-blowing!

“The 8‑core CPU in M1 is by far the highest‑performance CPU we’ve ever built. Designed to crush tasks using the least amount of power, M1 features two types of cores: high performance and high efficiency. So from editing family photos to exporting iMovie videos for the web to managing huge RAW libraries in Lightroom to checking your email, M1 blazes right through it all — without blazing through battery life.”

Intel Reveals Thunderbolt 4 Port

With technology modernizing, companies are working hard to keep PC and Macs innovative, up-to-date, and useful for everyone. Yesterday, Intel announced their upcoming universal cable, called the Thunderbolt 4.

This new connectivity port will allow a plethora of benefits, capable of amplifying the “minimum performance requirements, expanded capabilities and USB4 specification compliance,” according to the Intel Newsroom. It also features up to four port docks, giving quite the advantage for those requiring multiple ports for work purposes.

Jason Ziller, the general manager of the Client Connectivity Division of Intel, stated that, “the arrival of Thunderbolt 4 underscores how Intel is advancing the PC ecosystem toward truly universal connectivity solutions.”

They also shared the Thunderbolt 4 controller 8000 series, which would add a Thunderbolt 3 PC collaboration. The experience of using Intel’s ports is expected to receive positive feedback due to a rise in productivity.

Apple and Intel partnered together years ago, establishing the Thunderbolt to bring additional perks. So if you have a Mac, there’s a good chance you’ll find an Intel port. According to The Verge, “Apple is moving away from Intel’s chipsets in favor of its new, custom-designed ARM chips — but the company is promising that it’ll still support Intel’s Thunderbolt USB-C connectivity standard on new Apple silicon computers, despite the lack of Intel processors.”

In July 2020, Intel announces the Thunderbolt 4 controller 8000 series, which includes JHL8540 and JHL8340 host controllers for computer makers and JHL8440 device controller for accessory makers. Thunderbolt 4 developer kits and certification testing are available. (Credit: Intel Corporation)
Other benefits of Intel’s Thunderbolt 4 involve:
  • Thunderbolt Security protection
  • 2X minimum video requirements of Thunderbolt 3
  • PC charging on one computer port
  • and more!

At this time, the developer kits and testing for certification are accessible. And developers are excited about it.
