Understanding the Apple MacBook and Bluetooth Connectivity

Sunday, August 30th, 2009

You should know whether your MacBook supports Bluetooth connections. However, latest Apple laptops have internal Bluetooth component. If you’re using an earlier Mac laptop without built in Bluetooth, though, you’re certainly out of the Bluetooth loop. Even so, you don’t have to pitch your faithful Mac if it doesn’t yet communicate to other Bluetooth-enabled devices! You can add Bluetooth feature to your Macbook with a widely available USB Bluetooth adapter. A regular Bluetooth adapter sells online for approximately $30.

Your external Bluetooth adapter should have automatic data encryption capability, which can protect your Macbook if there’s a Bluetooth cracker within about thirty to sixty feet of your Macbook. The adaptor may link with up to eight other Bluetooth devices as the same time. (Come to think of it, if there are a lot of people within 60 feet of your MacBook Pro during a LAN party bash, you’ll guess this feature really is important!) You’d expect any modern and high-tech operating systems like Mac OS X should come with basic Bluetooth supports. You’d be right; however Apple goes one step further.

Your Macbook comes with System Preferences and utility software to help you get your Macbook connected with nearby Bluetooth devices.

Choose the System Preferences icon located in the Dock. With the Bluetooth pane, you can

* Create new Bluetooth devices. Just click the ‘Set Up New Device’ to open the Bluetooth Setup Assistant utility, which sets up other Bluetooth devices for connection with Leopard. Read the onscreen instructions to configure a number of common Bluetooth gadgets (including mice, cellphones, keyboards, and printers), or you can also choose Other, Setup Assistant will looks for other Bluetooth devices and adjust the settings so that those devices are ready to party with your MacBook. Be sure that Bluetooth devices are discoverable and in range (available for connection with your Macbook) before you open the Bluetooth Setup Assistant utility. Read your user manual to understand how to set a Bluetooth device as “discoverable”, the device should be about twenty feet away (or less) from your laptop.
* Set up Bluetooth connections. Choose the Advanced button to establish, remove, enable, or disable a Bluetooth connection, using a Bluetooth connection as virtual serial port (for the simple file transfer) or as virtual modem (for bidirectional transfer, including using Internet connection through a Bluetooth cellphone).

You may also specify if a Bluetooth port should be encrypted.

It is recommended that you activate the Show Bluetooth Status located in the Menu Bar check box. Luckily, the Bluetooth menu allows you to conserve power by disabling your Bluetooth feature until you need it. It is quite convenient to toggle your Macbook’s discovery status and also configure a device or send a file. It’s also easy to know which devices are connected to your Macbook.

If you won’t be connected with Bluetooth devices while you are on the road, disactivating a Bluetooth service on a Macbook will help save battery power. There is another handy Bluetooth resource, the Bluetooth File Exchange. You have to launch Bluetooth File Exchange the old-fashioned way; just go to your Utilities folder, inside the Applications folder. It’s quite similar to a traditional file transfer protocol (FTP) application, choose the Bluetooth File Exchange icon to go to the file selection dialog; then browse the file you want to send to a connected Bluetooth device. You can also choose to browse the file in other networked Bluetooth device so that you know what the user of that device is offering.

You may also configure your default settings for file exchange in the Sharing pane, which is located in the System Preferences. Just click the Sharing icon and then choose the Bluetooth Sharing check-box to display the setting parameters. Here you can manage what Leopard does when you get files or PIM (Personal Information Manager) data with Bluetooth File Exchange. For example, with this setting, Leopard can

Ask you for permission to receive a file or Personal Information Manager item

* Accept any files and PIM items without any prompting or restriction
* Keep all incoming items and files to a specified folder
* Restrict file-sharing only for the items and files in the specified folder when other Bluetooth devices browse your MacBook.

It is recommended that you use these default setting in Leopard for file exchange:

* You know when someone’s sending you something.
* Anything you receive will be saved in your Downloads folder.
* If you turn on the File Transfer, you can allow others to see the content of your Public folder.

Even so, feel free to enable, disable, and adjust the setting to your heart’s content.

Fix Mac Disk Errors

Sunday, June 21st, 2009

In this article we teach you how to fix MAC disk errors for the Apple Macbook using the operating system OS X10.4.x. If your MAC computer is no longer working as quickly, efficiently or effectively as it used to when you had just purchased it, chances are that there is some malfunctioning of the disks of the computer systems. Such problems are known as disk errors and need to be fixed as soon as possible to prevent further damage and to restore the computer to its optimal condition.

Customers of Apple using the Apple Macbook are provided with a disk known as the Apple Software Restore disk which is to be used for such times where an emergency arises and the disk needs to be cleaned of unwanted applications and kinks need to be smoothened out.

Getting started!

The first step is to place the disk into the disk drive and then choose the ‘restart’ option to begin loading the computer up again. Once the start up process begins again you will be alerted to it by the startup sound. After you hear this sound press the C key down and hold it so until the screen displays the Apple logo. The logo display is in tones of gray.

Once the computer has started up the disk will automatically begin to initiate the OS installation process. Be careful not to begin to reinstall the operating system yourself manually.

You might be presented with the option of choosing another language. To work with English, which is the default language, click on the Next tab.

What next?

A window with the option Utilities will pop up. Click on the window and then choose the Disk Utility button. This will start up the Disk Utility function which will pop up as a new window. Towards the left hand side of the window will be a list of the disks out of which you need to select the one which you wish to heal. For the present time being, you will select the option listing Macintosh HD. There will be a bar running horizontal near the upper end of the window with the option First Aid. It is imperative to select this option as well. At the lower end of the Disk Utility window, towards the right hand side, you will be a tab with the label Repair Disk. To start the repairing process click on this tab.

And lastly…..

This action will initiate a scan in which the system will go through the drive that you have chosen to repair and will check to see if there are any problems in the drive. If the drive is safe and free of problems a message stating the same will be displayed. If there are errors in the drive a window detailing the same will pop up. After reading through the list of problems detected by the scan you only need to click on Repair Disk and the computer will start to fix the problems within the drive on its own.

Disk Software

Another highly recommended option for the Mac is to use some type of disk management and backup software such as Disk Tools. Read the full review of Disk Tools here.

How To Recover From The Top 10 Crucial Mac Disasters

Sunday, March 22nd, 2009

1. Mac Keyboard Gets Liquid Exposure

Immediately disconnect the power cord and remove the battery from your Mac. Turn your Mac upside down at an angle to allow the moisture to drain out. Do not lay the machine flat because we want to separate the machine from the moisture. Be sure to have a towel or cloth underneath the Mac to collect the dry liquid. Be sure to allow at least 3 days to pass before you reinstall the battery and power up the Mac. This will allow the moisture to dry completely.

DO NOT USE A HAIRDRYER! Hairdryers can burn the liquid onto important Mac components which can cause a application or software malfunction. If you are desperate and money isn’t a concern, you can contact a data recovery company such as Techserve or DriveSavers after you pull the plug from your Mac. Another option is to take your Mac in to an Apple Store but remember food and liquid damage is not covered by Apple Care.

If you computer starts up, and you are a self sufficient type of guy, you may be able to do the next step by yourself. You will have to disassemble your Mac and swab down the affected area with distilled water or denature alcohol which is available at hardware stores. If you aren’t confident in dissembling your Mac, take it to a local Apple Store for cleaning. Be sure to clean the affected area because if left, the liquid may corrode the Mac’s inwards overtime.

2. Mac Stuck in StartUp Mode

What do you do when your Mac stays stuck on the start up screen? First step is to reboot the Mac and hold down the Command and S key as the Mac is starting up. This will allow you to boot in single user mode and you will see white text appear on your screen. Once you see the # command prompt, type /sbin/fsck/-fy and hit return. The Mac will go into file system consistency check.

Be patient this process may take anywhere from 15 minutes to an hour depending on the problem that is plaguing the Mac. Don’t be alarmed when you see the message “File System was modified”. Repeat the command prompt step again and again until you see a message stating “no problems were found”. Once this message appears, type in reboot.

If this doesn’t work and your computer is still stuck in start up mode, insert your OS X install disc into the disc drive and reboot. As the Mac is starting up, hold down the C key. If you are running 10.4 or later go to ApplicationsUtilitiesDisk Utility, select your hard drive and click Repair Disk on the First Aid tab. If there aren’t any disk errors, click Repair Disk Permissions. When this process is complete, restart your Mac.

If you are running OS 10.2 you can do the same steps except you will go to the InstallerOpen Disk Utility. If all the above fails, you will probably need to take your Mac to the Apple Store for professional repairing.

3. Mac Will Not Power On

If you attempt to power up your Mac and there is no start up chime, sound from the hard drive or Mac’s fan, and the light on the power indicator isn’t on, unplug you power cord and remove your battery. Also remove any other peripherals that may be connected such as printers, displays, etc. Now after waiting about 2 minutes, reconnect the battery and power cord to check if your Mac will start up normally. If it does, you are safe and can plug back in all peripherals.

If this doesn’t work, unplug the power cord and disconnect the battery again. Now try to reset the System Management Controller. If the System Management Controller’s file has been corrupted the Mac may not recognize it’s power supply. If you have a Mac Book or Mac Book Pro, hold the power button down for 5 seconds, then reconnect the adapter and press power to hopefully start up the Mac.

If you have a Mac Book Air you will need to hold Shift-Control-Option on the left side of the keyboard and press power. If you use another model, check with Apple Support, or Google the model name of your Mac + SMC to learn how to reset the System Management Controller.

4. Mac is Running Slow

One reason your Mac may tend to run slow is because a lot of applications and toolbars we may not use may be utilizing a lot of the Mac processing memory. Its time to erase / consolidate some of those resources you do not need. Create a new folder and put all the icons and folders into the newly created folder.

We do this because desktop icons and folders also use processing memory. If you want to consolidate even more, turn off some of the features you don’t need like animations, effects, and scrolling bars. The simplest way to do this is to use TinkerTool a free app that lets you customize OS X.

5. Mac Application Crashes

One cause of application failures could be because of system updates, downloading or installing a new piece of software or editing or changing the preferences on your Mac. If you have did none of the above the problem may be the application’s preferences. Go to ACCOUNTS create a new account and log in as the new user. If the application works with the new user account, the problem may be with the application preferences.

If this is the case you could either reset application preferences by holding down command+option+shift keys when starting the application or you could go to Users/Library/Preferences folder and removing the crashed application’s preferences. If you still can’t figure out how to reset the application default preferences, you could go to the manufacturer’s website.

6. Mac Makes a Mysterious Buzz Noise

If you hear a high pitched noise or weird buzz coming from your Mac’s hard drive that may be a warning sign it may be time to replace it. Another sign may be frequent application freezes or start up freezes. Also if files are starting up slowly or closing slowly that is another sign it may be time to replace the hard drive. Your Mac’s monitoring system may say the hard drive is o.k. but don’t take any chances! Back up the drive asap!

7. Macbook Gets a Scratch

Some people have tried the DIY approach to repairing scratches. I have heard stories of people taking their MAC in to jewelers to have the scratches buffed out. Other people have used put Vaseline into the scratch to mask it. You can try Apple Care but usually they won’t cover this.

One solution is TechRestore. TechRestore can replace a MacBook display anywhere from $350 to $500 depending on the display size of your MacBook’s screen. If you are handy and want to do it yourself, PowerBookMedic is a good source to purchase a new display.

8. Your Mac’s Fonts Are Going Exorcist

Small font files and corrupt files can cause application crashes and display issues. If you are running OS X (Tiger or Leopard) you can avoid by going into applications and launching Font Book. Once Font Book is open command click a group of fonts to check if they are corrupt and then select validate fonts. Bad files and corrupt fonts can enter your system from being downloaded from bad websites.

If a particular file is corrupt, you will see a round icon with an X on it. Click the box next to the bad font and then select Remove Checked to remove the file from your system. If there is a yellow warning sign next to the font, remove the font file from the Font folder, restart the system and hopefully this will resolve your issue.

If you are running an older OS system on your Mac I would suggest a font manager like Extensis Suitcase Fusion. This app is highly recommended and offer many ways to organize and work with your fonts.

9. SAFARI IS RUNNING SLOW ON YOUR MAC

If Safari is having performance issues try Resetting Safari (go to Safari>Reset Safari). Doing this will give you the option to delete stored login information, cache, favicons, history, and cookies. Before you delete everything try only deleting cache, favicons, and history first.

10. REMOVING SCRATCHES FROM YOUR IPOD OR IPHONE

Many people use toothpaste! Yes toothpastes can be used to remove the blemishes and scratches on your screen but I wouldn’t recommend it because certain brands of toothpaste may be more abrasive and could possibly add more scratches.

One solution I would suggest is Applesauce polish. Applesauce is simple to use, just follow the self explanatory directions.
