Mac computer suddenly special card

Apple notebook is becoming more and more popular because of its thin body, aluminum alloy shell and different OS systems. Due to the continuous improvement of people's living standards, Apple notebooks have gradually become popular. Although Apple's notebook has many advantages, apart from the high price, it is not too awesome to go wrong. Today, Bian Xiao will tell you how to rescue Apple's notebook quickly when it goes wrong.

Problem 1: The system boot card is in boot mode.

If your Mac card does not move for a long time in the startup screen, you should pay attention at this time. It is very likely that your hard disk is broken, and of course, the system failure is not ruled out. So let's solve the simple problem first. Turn off the phone, press the power button, and then press and hold Command+S, you will enter single-user mode, and then see the white text displayed on the screen. When you see the # command prompt, type/sbin/fsck-fy–fy and press enter. At this time, the computer self-checks, and if there is a fault, it will try to repair it automatically. This process takes about 15 minutes. If the problem is not solved, 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 select the application availability disk utility option, then select your hard disk, and then select repair disk to wait for the hard disk to be repaired. If there are no errors on the disk, click Repair Disk Permissions, and then restart the computer. If your system is 10.2, please repeat the above steps, but the program directory is in the InstallerOpen Disk utility.

Question 2: It is not displayed when the computer is turned on.

Press the power button to start the machine, the system does not respond, the indicator light does not light up, and the fan does not turn. Don't be nervous. Let's disconnect the power cord first, then take out the battery, wait 1 minute, and then put the battery back in place and try again. If this method doesn't work, please unplug the power cord and battery again and reset the system management controller. There may be a problem with the settings of the SystemManagement controller. Then press and hold the power button for 5 seconds, and then turn on the power to start the computer. Other mobile versions of Macs are slightly different. The specific operation process can refer to Apple Support or Baidu SMC+ your computer model.

Question 3: The computer is stuck.

If you find your MAC card, it is likely that there are too many junk or downloaded software, resulting in too many startup items. At this time, it is necessary to optimize the computer. Just like we use windows, we need to optimize the system frequently to run fast. At this time, we can use software optimization to download TinkerTool, a very practical free software. At the same time, if possible, you can clean up the computer. If your MAC computer has a severe fever in winter, you should be careful. If you don't want to burn the computer, it is recommended to clean it up, that is, to speed up the operation of the computer and avoid burning it out. Finally, see if there is something wrong with your memory. If your system crashes without any 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 4: The software reported an error or could not be opened.

If a software can't be opened suddenly, or an error is reported directly, it is necessary to check whether the computer system has been upgraded recently, or some settings have been modified. If you change the settings, you have to change them back to see if the software needs to be upgraded or reinstalled. 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. For software such as Photoshop, you can hold down Command+Option+Shift when the software starts to restore the default settings.

Question 5: The font is garbled.

If your computer font is garbled, it's probably your font. The garbled font file will lead to printing or display errors, and even damage the program. At this point, you can enter the Applications folder, and then start Font Book to check the broken font file. 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.
