Cleaning the laptop fan and repasting once a year would be nice, or if the computer is heating up than normal.
There are lots of application that monitors CPU and GPU temperature,
If you want to refresh the thermal paste / repaste your laptop, This is what we normally use

Follow these instructions to uninstall MacKeeper. They have been tested with the most recent version of MacKeeper. Earlier versions than the one released in 2012 require more extensive work to uninstall all its components. Never install such junk on a Mac.
If you actually used MacKeeper to alter your system, e.g. "remove excess binaries" or such, you will need to reinstall OS X as well as all your additional software. Uninstalling MacKeeper is insufficient to reverse the corruption it is capable of - once again, that is if you used it.
If you merely installed MacKeeper but did not use it to perform any particular action, the following instructions will suffice.
If you used MacKeeper to encrypt any files or folders, use MacKeeper to un-encrypt them first.
Quit the MacKeeper app if it is running.
Open your Applications folder: Using the Finder's Go menu, select Applications.
Drag the MacKeeper icon from your Applications folder (not the Dock) to the Trash.
You will be asked to authenticate (twice):
You do not need to provide a reason for uninstalling it:
Just click the Uninstall MacKeeper button. You will be asked to authenticate again.
After it uninstalls you may empty the Trash and restart your Mac. All that will remain is an inert log file that does nothing but occupy space on your hard disk.
May I suggest that you review the following setting in System Preferences?
Although you may easily override that setting, it will serve to protect you from inadvertently installing garbage. The overwhelming majority of Macs I come across have the MacKeeper installer file already present in their Downloads folder, often multiple copies of it. The downloaded file itself can do nothing until it is opened and installed, and the above setting (known as Gatekeeper - not to be confused with MacKeeper) will prevent that from occurring.

Never install any product that claims to "speed up", "clean up", "optimize", or "accelerate" your Mac. Without exception, they will do the opposite.
Never install pirated or "cracked" software, software obtained from dubious websites, or other questionable sources. Illegally obtained software is almost certain to contain malware.
Don’t supply your password in response to a popup window requesting it, unless you know what it is and the reason your credentials are required.
Don’t open email attachments from email addresses that you do not recognize, or click links contained in an email:
Most of these are scams that direct you to fraudulent sites that attempt to convince you to disclose personal information.
Such "phishing" attempts are the 21st century equivalent of a social exploit that has existed since the dawn of civilization. Don’t fall for it.
Apple will never ask you to reveal personal information in an email. If you receive an unexpected email from Apple saying your account will be closed unless you take immediate action, just ignore it. If your iTunes or App Store account becomes disabled for valid reasons, you will know when you try to buy something or log in to this support site, and are unable to.
Don’t install browser extensions unless you understand their purpose. Go to the Safari menu > Preferences > Extensions. If you see any extensions that you do not recognize or understand, simply click the Uninstall button and they will be gone.
Don’t install Java unless you are certain that you need it:
Java, a non-Apple product, is a potential vector for malware. If you are required to use Java, be mindful of that possibility.
Java can be disabled in System Preferences.
Despite its name JavaScript is unrelated to Java. No malware can infect your Mac through JavaScript. It’s OK to leave it enabled.
Block browser popups: Safari menu > Preferences > Security > and check "Block popup windows":
Popup windows are useful and required for some websites, but popups have devolved to become a common means to deliver targeted advertising that you probably do not want.
Popups themselves cannot infect your Mac, but many contain resource-hungry code that will slow down Internet browsing.
If you ever see a popup indicating it detected registry errors, that your Mac is infected with some ick, or that you won some prize, it is 100% fraudulent. Ignore it.
Ignore hyperventilating popular media outlets that thrive by promoting fear and discord with entertainment products arrogantly presented as "news". Learn what real threats actually exist and how to arm yourself against them:
The most serious threat to your data security is phishing. To date, most of these attempts have been pathetic and are easily recognized, but that is likely to change in the future as criminals become more clever.
OS X viruses do not exist, but intentionally malicious or poorly written code, created by either nefarious or inept individuals, is nothing new.
Never install something without first knowing what it is, what it does, how it works, and how to get rid of it when you don’t want it any more.
If you elect to use "anti-virus" software, familiarize yourself with its limitations and potential to cause adverse effects, and apply the principle immediately preceding this one.
Most such utilities will only slow down and destabilize your Mac while they look for viruses that do not exist, conveying no benefit whatsoever - other than to make you "feel good" about security, when you should actually be exercising sound judgment, derived from accurate knowledge, based on verifiable facts.
Do install updates from Apple as they become available. No one knows more about Macs and how to protect them than the company that builds them.
Summary: Use common sense and caution when you use your Mac, just like you would in any social context. There is no product, utility, or magic talisman that can protect you from all the evils of mankind.

I wanted to know how to unlock my iphone, since I had to restore it and when it restarted, it appeared this message: "The SIM card que you currently have installed in this iphone is from a carrier that is not supported under the Currently actuvation policy that is assigned by the server activion. this is not a hardware issue with the iPhone. Please insert another SIM card from a supported carrier or request que this iphone be unlocked by your carrier. Please contact Apple for more information. "
I need help, I use my phone for everything enclusive to work. I appreciate if you can help. I'm from Brazil. My name and giullia.

Did you purchase this device from Apple or an authorized reseller? It sounds as if you had a device that was jailbroken/hacked to operate on your carrier. Upon updating the iOS, it is now locked back to the original carrier the device was locked to.
Only the carrier the device is locked to can authorize an unlock. You will need to make contact with that carrier and see if they provide unlocking services, and if they do, if you qualify for an unlock. Otherwise, you are out of luck. One that carrier can take care of the unlocking.

Want to know how to check for new line character in text file

Hi All,
I`m trying to read data from text file. However I`m not sure whether the data is in 1st line or nth line. Now I`m trying to read the text from the readline. But if text is "" and not NULL then my code fails. So I want to know how to check for new line character and go to next line to find the data. Please help.
Thanks

          try     {
          if(new File(filepath).exists())
          fr= new File(filepath);
                    System.out.println("FileName: "+fr);
               if(fr != null){

     else{

     out.write("0");
            out.close();
               }          //Reading of the row count file ended.

               e.printStackTrace();
          finally {
               try{               if (in != null) {
                         in.close();
          if (out != null) {
                         out.close();
          catch(Exception e) {
                    e.printStackTrace();
          return get_count;

You are calling the readline() only once which means you are reading only the first line from the file...
Use a loop (Do-While preferably)
do{
//your code
}while(text == "")

I want to know how to take music out of other folders in my iTunes...

I can't take music from other folders on my iTunes and put them on my iPod. I want to know how I can do this, because I feel like I have tried everything but I may not have tried everything. Can someone tell me how I can go about doing this; taking music from another folder and or file from my iTunes and put them onto my iPod.

Your post is somewhat confusing. If all of your music is in your iTunes music folder, it should sync to your iPod. If you have music on your system's HD that is not in iTunes, you will need to use the "add file or folder" function in iTunes to bring these other files into the iTunes music folder.

I have an airport express and want to know how to set up two different wireless networks. One with 5GHZ and one with 2.4GHZ so different devices can connect to either.

I have an airport express and want to know how to set up two different wireless networks. One with 5GHZ and one with 2.4GHZ so different devices can connect to either. I have an iphone 4 that will not connect to 5ghz.
thank you!

Your AirPort Express is already providing two separate 2.4 GHz and 5 GHz bands, but each band is using the same wireless network name.
This is the default setup for the AirPort Express, which is recommended for most users. The theory here is that devices will automatically connect to the best quality signal based on their capabilities and distance in relation to the AirPort Express.
It is possible to assign a different name to the 5 GHz band, and then "point" devices at that network to connect. Some users swear by this option.....(I am not one of them).... but you might want to give it a try to see how it works for you.
Open Macintosh HD > Applications > Utilities > AirPort Utility
Click on the AirPort Express
Click Edit in the smaller window that appears
Click the Wireless tab at the top of the next window
Click Wireless Options near the bottom of the next window
Enter a check mark next to 5 GHz Name.....which will automatically add "5 GHz" to the network name....so you can identify it
Click Save, then click Update and wait a full minute for the Express to restart
Now you will need to "point" your 5 GHz capable devices at the 5 GHz network name. 2.4 GHz devices will connect to your "other" network name.

I have an ipad 2 and I noticed I have over 3000 emails in All Mail. I want to know how can I delete these emails. It looks like you can only do it one at a time. It will take me forever. Please help me.

I have an ipad 2 and I noticed I have over 3000 emails in All Mail. I want to know how can I delete these emails. It looks like you can only do it one at a time. It will take me forever. Please help me.

You can only delete them one at a time on the iPad. If you have an IMAP email account, go to your email in on the server using a web browser and select as many as you can at a time and delete them that way. That action will be reflected on the iPad. In IMAP - whatever you do on one device syncs across all devices. If you have POP email - start deleting one at a time.

I have an old ipod and want to know how to get everything off it and into my iTunes library. My old computer died and the original library was lost, so don't have any of the content saved anywhere else.

I have an old ipod (it's the very thin oblong one in purple, the one before the one that does video) and want to know how to get everything off it and into my iTunes library. My old computer died and the original library was lost, so don't have any of the content saved anywhere else. I now have an iPhone 5S and listen to music on that, so want to be able to listen to things from the old ipod too.
Can anyone help please?
Thanks very much
Jane

Apple normally does not get involved in handling lost objects like this. Since a real name is not installed it will be much more difficult.
You can try contacting Apple support at the US number, assume you are US going to BWI from the listing: http://support.apple.com/kb/HE57 and explain the situation and see if they offer any suggestions.

There are many apps in the App Store for transferring files between a computer and an iPhone using a cable, WiFi, or a cloud connection. Box and Dropbox cloud services are the easiest to use; I use Dropbox routinely to transfer business documents to our offices around the world.
Evernote is another widely used cloud service.
For local WiFi transfers there's Documents to Go, Airsharing, QuickOffice, and several dozen more. Documents to Go and QuickOffice also let you edit MS Word documents on the iPhone.
