If PC is sometimes stubborn and willful, then Mac is a bit difficult to deal with. Usually, they will only rebel when their living conditions are extremely bad, such as giving a MacBook some juice or something. Just like people, Mac works long hours and needs a little rest.
No matter what's wrong with Mac, there are ways to solve it by yourself. Sometimes with luck, the problem is obviously solved. If an application doesn't work well after upgrading the operating system, you may subconsciously think that that application may also need to be upgraded, right? More often, solving Mac problems may require you to confirm a few simple steps, starting with the most obvious and simple: are your wires plugged in the right place? If it is too complicated for you to handle, calm down, be sure to calm down, and don't break anything, especially your Mac.
Next, we will introduce you to the solutions to common Mac problems of 17, including Macs, iPhone and iPod. If you are really not sure that you can handle them well, I suggest you be careful not to make things worse. You should take your machine to a professional maintenance company and ask them to repair it for you. Of course, don't forget to backup your data. If you don't have a backup, a small problem can cost all your work. Leopard user, you have a time machine in your machine. Don't tell me you don't know how to back it up! )
Question 1. The keyboard was splashed with water!
Survival tip: If you accidentally spill water or other liquid on the MacBook keyboard, you need to clean the liquid on the surface super quickly. Cut off the power immediately, and then take out the battery. Then turn the top cover of the computer upside down and let the liquid flow out slowly. Do not shake or lay flat. You need to dry it. Absorb the water under the machine with paper or dry cloth, and replace it in time if necessary.
No matter what is spilled on your computer, don't turn it on for 72 hours. Before you start the machine, you need to make sure it is dry. Some people may use a hair dryer, but if you dry it with a hair dryer, the contents in the liquid (if it is not 100% water) will remain on your machine parts, so it is best to dry it naturally. If you really need the data on the computer, I'm sorry, get 600 yuan ready, and then go to the data rescue company.
If your data has been backed up, you just want to know whether your computer can still be used. You just have to wait for it to dry and see if it can be started. You can choose whether to take it to the Apple Store for repair or find a place nearby where you can repair apples. Please note that if the damage is caused by liquid, Apple is not responsible for it. Maintenance personnel are not stupid. Don't lie to them. It suddenly stopped working? Wait)
If you choose to save yourself and the computer has been started, it depends on what you spilled. Ordinary warm water should not be a big problem (it is not a good thing to heat the motherboard with ice water). Mac can also tolerate sugar water, acid, milk and so on, but the problem may appear after a while, because these liquids will corrode your computer hardware. So you need to clean up your computer at once. If you are sure that you have the ability to disassemble your computer, wipe all the spilled parts with distilled water or industrial alcohol and put them back intact. If not, go to the Apple Store.
If you spill water on the external keyboard, please quickly unplug the keyboard from the computer, and then turn the keyboard upside down to suck up the water. Then air it for 24 ~ 48 hours, and then insert it back.
Question 2: Stuck in startup mode.
Survival skills: If your Mac card stays still for a long time in the startup screen, please take a deep breath, then turn off the computer and select the self-test mode.
Press the power button, then hold down the Command+S, and you will enter the single-user mode, and then see the white text displayed on the screen.
When you see the # command prompt, type /sbin/fsck? Fy, and then get into the car. Then you can wait for your Mac to self-check, see what's wrong and fix it yourself. This process will take about 15 minutes, please be patient.
If it doesn't work, put your OS X system disk in the CD-ROM drive, restart the Mac, and hold down the C key. If your system is 10.4 or later, please enter the application SutilitiesDisk utility, select your hard disk, and then click RepairDisk. If there are no errors on the disk, click Repair Disk Permissions. After completing all the steps, restart the Mac.
If your system is 10.2, the above steps are the same, but the program directory is in the InstallerOpen Disk utility.
Not yet? Go to the Apple Store.
Question 3: Do not start.
Survival skills: If you press the power button, but the system doesn't respond, the indicator light doesn't light up, and you can't hear the sound of the fan? .. first, take a deep breath! Then unplug the power cord. If it is a notebook, take out the battery, disconnect all peripherals, and count from 1 to 60. Reconnect your battery and power cord to the street and see if the machine can start.
If not, unplug the power cord and battery. Attempt to reset the system management controller. The reason is that if there is a problem with the system management controller settings, your Mac will not be able to recognize the battery or power supply. On macbooks and MacBook Pro, press and hold the power button for 5 seconds, and then connect the power to start the computer. Other mobile versions of Macs are slightly different. The specific operation process can refer to Apple Support or Google SMC+ your computer model.
Question 4: Running too slowly.
Survival skills: If your Mac is as slow as an ox, it's your fault. You just download some software that you will never use several times in your life. Your desktop is full of folders and icons. Looks like you should clean it up. Uninstall unused software, tidy up folders (you know that every small icon on the desktop will occupy some system memory), and turn off some system functions, such as system animation, stretching effect, smooth scrolling and so on. The easiest way is to download this free TinkerTool (www.bresink.de) and do some system setup work.
Then, consider the sleep state of your Mac. The OS X system runs automatically at 3: 15 every morning, 4:30 every Saturday morning or 5:30 on the first day of every month by using UNIX scripts. If your computer is turned off or sleeps at these times, the temporary folder of the system will be full of junk files, and your Mac will definitely not run fast. If you use Leopard, the script will run every time you start it.
Question 5: The power supply is on fire! ! !
Survival skills: Another reason is that your Mac runs slowly, crashes, shuts down for no reason, or can't play videos smoothly. Dust, dirt or pet's hair is blocked in the machine, which will make the machine hot. If left unchecked, your Mac will be slowly roasted to death.
To solve this problem, you need to open the cover and blow it clean with a hair dryer. If you can turn on the Mac yourself, it's a piece of cake for you. If you are not sure, you'd better find Pingguo Store. If you just want to blow away the floating dust on the surface and don't want to do any deep cleaning, then stop blowing pictures and tilt the hair dryer at a certain angle.
Apple said that some MacBook have a thin layer of plastic on the back cover. This was originally used for dust prevention in factory production, and should have been removed when it was delivered, but some computers did not. If there is still plastic on the back cover of your MacBook, take it off and throw it away. Make sure that the vents at the back of your computer are not blocked by anything, or are slowly blocked because they are placed on soft surfaces or legs. Your computer needs breathing.
Question 6: The software doesn't work.
Survival skills: If a software has good performance, but suddenly it doesn't work, it must be your fault. Have you upgraded your system? Have you installed any other new software? Or have you changed any settings on your computer? You also need to upgrade the disobedient software.
If not, it depends on whether the software itself is set incorrectly. Create a new account and log in with the new account to run the software. If there is no problem, it means that your commonly used account settings are wrong. You can know the previous settings, and the directory is in the users/library/preferences folder. For example, in a software like Photoshop, when the software starts to restore the default settings, you can hold down Command+Option+Shift.
Damaged fonts can also make your software run abnormally. You can see how the problem 14 solves them.
Finally, is there anything wrong with your memory? If your software crashes without warning, there may be something wrong with your memory. Then check the memory. Everything is easy to find except air. Try another memory slot.
Question 7: My Mac scratched the bird ~ ~ ~
Survival skills: metal surfaces are easy to scratch, and the fact is so cruel. The first scratch always hurts, but if you scratch too much, you won't feel it. But if you really can't, you can try to use scratch-resistant paint, but you must follow the instructions. Then avoid the paint touching the radiator, joint or joint of your back cover. If your Mac is dirty or scratched, I suggest you try the Apple Polishing and Cleaning Set.
Question 8: dirty MacBook
Survival skills: The white MacBook will get dirty in a short time, especially at the wrist rest, and the black one will be smashed by the oil flowing out of your fingers. But you can try to wipe Colin.
Question 9: The button is loose!
Survival skills: If the keys on your keyboard drop: whether it's an old Apple computer or a new aluminum keyboard, you are unlikely to press them back. Turn the button upside down and see if the plastic card is still there. If it's still there and it's not broken, please gently open the clip and do everything you can to press it back, first to the right and then to the left. Now you need to put the keycap back. You may need a toothpick or something thin to fix the keycap. Remind friends with aluminum keyboards that those non-letters and numeric keys are very difficult to handle, because those things that drag them are very easy to bend unless you are very light.
If the plastic clip is broken, you have to check online to see if anyone sells it.
Question 10: Noise, noise.
Survival skills: If your Mac has any strange sound coming from the hard disk, whether it is high frequency or low frequency, then your hard disk may die soon. Others, such as frequent unresponsiveness of applications, mysterious disappearance of folders, frequent startup crashes, or slower opening or saving files, immediately back up your data, even if your Apple Disk Tools says your disk is in good condition.
In fact, you should be glad that your computer reminded you in advance. Generally speaking, this kind of reminder always appears in the form that the computer can't work. So don't ignore backup ~ ~
Problem11:There are scratches on the screen of iPod or iPhone.
Survival skills: Some people say that toothpaste can take out the fragile screen scratches of iPhone or iPod. The gentle grinding effect of toothpaste can not only whiten teeth, but also remove scratches on iPhone/iPod, just like we use toothpaste to clean jewelry. But we found that some toothpastes were too strong for iPod/iPhone. Why not use something professional: applesauce polish or RadTech? s Ice Cr？ Me.
Question 12: the scratch came from MacBook ~
Survival tips: If the MacBook screen is spent, don't do it at home. Any tool that can remove scratches will also damage the protective coating on the screen. We heard that some people use computers to find jewelers to clean scratches, and some people use vaseline, but we don't recommend this practice. If scratches really bother you, don't hesitate to change the screen. Of course, your Apple Care protection plan will not pay for it. But you can go to the Apple Store and say that my screen has faded.
Question13: Did the iPod take a shower?
Survival tip: Did you drop your iPod/iPhone into the water (bathtub, toilet, or sea? If it is still on, please turn off the machine quickly. If it has been closed, then we just say: amen? If the equipment is turned off before falling into the water, please dry it thoroughly. If a large amount of water has been removed, install the equipment so that no water remains in the bottom housing. If you know how to take it apart, take off the battery. Dry it for 72 hours, and then try to turn it on. If it can't be turned on, it will be broadcast for another 48 hours.
Problem 14: font disorder.
Survival skills: small fonts cause big trouble! Damaged font files can cause printing or display errors, and even damage the program. Create confusion on the screen.
In OS X system, you can enter the application folder and start the font book to check the damaged font files. If yes, hold down the command and click the suspicious font file, and then click File >; Verify the font. If the font is broken, you can see a circular X icon. Select the damaged fonts, and then delete them. If you see a yellow warning icon next to the font, please move it out of the font folder and restart to see if the problem has been solved.
Question 15: Safari is on strike.
Survival tip: if Safari is not as diligent as before, please restart Safari > reset safari. This will clear the login information, favorites, cache, history and cookies stored in safari. If it is completely emptied, you will find that the speed has been obviously improved, but your websites that need passwords will have to be restarted. If you can't remember your password, just leave cookies and login information and empty everything else.
Question 16: MobileMe broke into chaos.
Survival skills: This proves that Apple will also release such a software with serious problems. If you want to continue using software that even Apple admits is flawed, you should back up all your data, synchronize it through the cloud, and then restart iSync. System preferences & gtMobileMe, click Sync/Advanced, and then click Reset Sync Data. Select all data from the pop-up window. If only part of the data has problems, select those problem households. Right-click and you will see? Use the synchronization information on this computer on MobileMe. ? Words.
Question 17: still MobileMe?
Survival tip: If 16 doesn't solve the problem, or you receive a message with conflicting data, reset the synchronization service folder, select preferences from the iSync menu, and then click Reset Synchronization History. If you have multiple Macs, you need to run it on all computers.
