How To Erase And Factory Reset Macbook Pro

Currently I owned three old laptops. Those three laptops are running with three different operating systems. My first purchased was my Acer Timeline X which is 10 years old now. The installed OS is Windows 7 Home. I used this for editing photos especially photoshop. Although a bit outdated but running in a good condition. My second is the Sony Vaio 13" laptop. It is not actually mine but since no one is using it, I  considered it as officially mine.  The operating system before was Windows 7 Home but I had changed  in to Kali Linux for  educational and learning purposes. Changing the system from Windows 7 to Kali Linux is not that complicated if you have gathered all the information before you proceed to reinstall it otherwise your laptop will be compromised. 

My 3rd is my Apple Macbook Pro 13" 2012 laptop which is having a Catalina OS. This is a 9 years old laptop but it works like a beast. A very powerful machine yet it has only a 128GB SSD HD and 8 GB 1600 DDR3 memory.  

To erase and factory reset please follow some steps. Firstly, you must backup all your important files and save it to the other external drive. Next, sign out all your iTunes, iCloud and iMessage then shutdown your machine. After shutting down press altogether the following keys from your keyboard which are Option Command and R then hit the power button. Do not release and keep your fingers on hold in the keyboard until you  will see the the spinning circle (earth). From there you will be given options from MacOS Utilities.

Choose and click Disk Utility and start erasing Macintosh HD. After erasing the HD click the option Reinstall MacOS then follow and read the steps.  Done. You have now a  fresh and newly installed OS. 

iPhone 4s SIRI and iPhone 4

Now you can use your voice to use your iPhone. Just talk to Siri as you would to a person: “Do I need an umbrella?” or “Any great burgers around here?” or “Where’s the closest ATM?” Siri not only understands what you say, it knows what you mean.¹ It figures out the right apps to use to find the right answer. Then, just like a personal assistant, it answers you. Siri makes phone calls, sends messages, schedules meetings, sets reminders, and more. How much more? Just ask, and Siri tells you that, too.

Apple iPhone 3G will last only for 3 more hours

The latest incarnation of Apple’s mobile device, the iPhone 3G, lasts for only half a day (or just a few hours if you’re a heavy user) on a fully charged battery. And since it does not have an accessible battery compartment, you won’t be able to replace the drained battery with a new one, either.
Moreover, for such an expensive device, the 16GB prepaid kit costs P43,799 while the 8GB, P37,599, it does not have a “business card” feature or even a text-forwarding function, important items for text-savvy Filipinos.

Nahh! What The Fact!! iPhone 3G is in my wishlist. By this month Im planning to buy a new one to preplace my old one. But Im a heavy user and I don't want to get it drain so fast. Ahh, I'll get the battery of my uncle's car and Im sure it will take days before it will get drain. Huhh! That's too heavy and bulky. I don't have a pack bag for that. Ah ok, I'll find some later. lolz.

What is a 3G?

3G or third generation, is the generic term used for the next generation of mobile communications systems. The new systems will enhance the services available today and offer multimedia and internet access and the ability to view video footage.

iPhone 3G. With fast 3G wireless technology, GPS mapping, support for enterprise features like Microsoft Exchange, and the new App Store, iPhone 3G puts even more features at your fingertips. And like the original iPhone, it combines three products in one — a revolutionary phone, a widescreen iPod, and a breakthrough Internet device with rich HTML email and a desktop-class web browser.

I'll buy this iPhone by the time it will be launched here in the Philippines. I heard from the news that Globe telecom is the first telecommunication company to introduce it to the public. From now on I will start soliciting money from the street where I live. (crying out loud!)
