Partitioning and formatting drives in OS X is much different than it is in Windows, even though the concepts are similar. Apple’s Disk Utility application ships with OS X, and it is simple yet powerful. It gives you a great deal of control over your disks by Apple Computer Repair Hong Kong and Mac Repair Hong Kong.
1. Connect your drive to the Mac. If you have an internal hard drive, follow Apple’s instructions for installing it in your machine. If you have an external USB or FireWire hard drive, plug the drive into a port and power it up.
If you are using a Flash drive, simply plug it into the USB port. If the drive is already formatted, OS X will mount it, and it will appear on the Desktop. If OS X cannot read the drive’s format (or if it is not formatted), OS X will prompt you to partition and format it.
2. Launch the Disk Utility application if it has not already launched.
3. Choose the disk you wish to partition from the list in the left pane, and then click on the Partition button. The current partition information, if there is any, will appear in the right pane of the window.
4. Choose the Volume Scheme from the drop-down menu in the right pane of the screen. If you choose to create multiple partitions, you can resize the partitions by dragging the divider between them on the screen, or clicking on an individual partition and entering the size in the Size field.
5. Enter the Name of each partition, and choose the Format from the drop-down menu. If you want to use the partitions on Windows machines, make sure to choose FAT as the format type.
6. If you would like to boot from either of the partitions, click on the Options button. If you would like to boot an Intel Mac, choose the GUID Partition Table. If you would like to boot a PowerPC, choose the Apple Partition Map. If you would like to boot a Windows computer, choose Master Boot Record. Once you are done, clickOK.
7. When you are satisfied with the settings, click Apply. OS X will unmount the disk, repartition it, and mount the partitions on the Desktop.
1. Choose the partition you would like to format from the list of partitions and drives in the left pane.
2. Click the Erase button.
3. If security is an issue, click on the Security Options button. You will be given additional erase options, including performing a zero-fill, and performing multiple-pass erases. Choose the option that suits you and click OK.
4. When you are satisfied with the settings, click the Erase button near the bottom of the window. OS X will unmount the partition and perform the erase actions you selected. When it is done, it will re-mount the partition.
5. Repeat steps 1-4 for additional partitions and disks you would like to erase.
When you are done, if you would like to shut down, disconnect, or eject the disks, don’t forget to unmount them so your data does not get damaged. To do this, you can drag the disk images on your Desktop to the trash.

Whether you like to travel a lot or just like to surf the web from the local coffee shop, you cannot deny that freely available public wi-fi is a very useful amenity.
The problem is that you do not know who around you could be attempting to steal your personal information via that same public wireless network, or just peeking over your shoulder to steal your password. There are a few ways recommended by Laptop Repair Hong Kong & Computer Repair Hong Kong so you can protect yourself when you are surfing the web from a public access point.
Do Not Make Purchases or Tinker with Online Banking
Even though it may seem like an obvious security precaution, you may want to refrain from making any purchases or logging into your online banking account. Someone may be able to obtain your password or credit card number, and the websites you are connecting to may not be secure. A little paranoia may be enough to keep your personal information safe.
Secure Your Laptop
If you have to run to the bathroom or leave your laptop for more than a minute or two, make sure that you secure it. Lock it with a password, so no one can look at what you were working on while you’re not there. If there is no one trustworthy you can ask to keep an eye on your laptop (store employee, librarian, friend, etc.), pack it up and take it with you. You may lose your table or your seat, but it will be a lot less difficult to find another than it will be to battle identity theft recommended by Laptop Repair Hong Kong
If you have a Bluetooth enabled laptop, make sure that the Bluetooth is off or that it is not in discovery mode. This also applies for smartphones. Once you have paired your devices, there is no need to leave them in discovery mode. We recently spent some time in a Barnes & Noble Bookstore, and were surprised to find out how many laptops and smartphones we discovered from our own laptop.
Use a VPN Connection
Most of us only use VPN () connections if they are issued through our place of employment. A VPN creates a secure tunnel between you and the sites that you are visiting, and that additional level of security will keep out the snoopers that may congregate at wireless access points.
If you do not have VPN, you can get free VPN through Hotspot Shield. Hotspot Shield will protect your anonymity by hiding your IP address. If you do not log in to a web site, you cannot be identified while running Hotspot Shield.
Once you download and install Hotspot Shield, double-click the Hotspot Shield Launch icon on your desktop. Hotspot Shield will create the VPN tunnel and let you know when the connection has been secured. Once you are connected, you can access the application from your system tray. Hotspot Shield is also available for OS X.

Mac OS X is a pretty sweet operating system. Most Mac users are generally satisfied with their choice of OS X. However, there are still those times when good old Windows would come in handy.
Luckily, you don’t need to make a “full switch from OS X to Windows” if you have a Mac. You can run both OS X and Windows from the same computer. Experts like Apple Computer Repair Hong Kong, Mac Repair Hong Kong or Computer Repair Hong Kong can help you with these installations. Thus, installing Windows on your Mac.
In fact, a good percentage of Mac users choose to run both Windows and Mac, particularly for things like gaming, Windows Microsoft Office, etc… There are a variety of ways that you can run Windows on a Mac computer. Here are some of the most popular.
Mac computers (iMac, Mac Pro, Mac Mini, MacBook, Macbook Pro, MacBook Air) all come equipped with Apple’s Bootcamp software. Bootcamp allows Mac users to run a second operating system, like Windows 7, on a Mac by partitioning their hard drives.
As the name suggests, using Bootcamp requires that you boot into one operating system or another, at startup. Bootcamp is completely free to use. One pro of using Bootcamp is that you get a direct install of Windows.
Whether you are using Mac OS or Windows, you are only using one operating system at a time. Thus, all of your computers power goes to running that operating system.
One downfall of using Bootcamp is that you cannot easily share files between Mac OS X and Windows. Also, you have to restart your computer each time you want to switch operating systems reported by Apple Computer Repair Hong Kong
Parallels Desktop is a premium virtualization software for running Windows on a Mac. In fact, Parallels was the first official software allowing Windows to be run within OS X via virtual machines.
Installing Windows on a Mac using Parallels is very simple, and similar to installing any program on a Mac. Simply install Parallels, insert a Windows 7 DVD, flash drive, or ISO file, and install using a step-by-step wizard interface.
One strong benefit of using Parallels is that you can run Mac and Windows simultaneously, making file sharing between the two operating systems extremely easy.
Parallels opens and closes just like any other application on a Mac, meaning no restarts required to use either operating system. One disadvantage of using Parallels is that it eats up more of your Mac’s memory, but it’s not really a problem if you have at least 2GB of RAM. reported by Mac Repair Hong Kong.
Vmware Fusion is another virtualization software, very similar in nature to Parallels. Fusion does differ from Parallels in that it has a different layout, interface, and a couple of different features. However, the functionality, pros, and cons are the same.
Virtual Box is a 3rd virtualization software allowing Mac users to run Windows using virtual machines. Although it holds the same basic concept of Parallels and VMware Fusion, it does not have as many bells and whistles. No complaints though, Virtual Box is open source, completely free.
Three out of the four major ways to run Windows on a Mac are virtualization software. Bootcamp, the non-virtualization method, is a great way to run Windows on a Mac completely free.
However, it does have some disadvantages. Virtual Box, the free virtual machine software, offers the same core concepts of the two premium applications, Parallels and VMware Fusion. However, it does not have the simplicity and convenience of Fusion and Parallels, and does lack some premium features.
