Problems encountered during use of MacBook and Solutions

1. Mac cannot be started

The application is not closed after Mac is used todayProgramSimply put the Mac lid together, and then the boot won't be available (always flashing). At that time, I felt like Apple's products were too brittle. However, after searching online, the problem was quickly solved.

The solution is as follows:

Reset SMC (that is, restore the initial settings of the motherboard, which can solve non-hardware problems on Mac). The specific operation is to press and hold down the shif + Control + Option + power key on the left of the computer, 5 seconds later, press the power button to start the computer.

 

2. Your security preference settings only allow installation of apps from MAC App Store and recognized developers

This problem is very crashing, but the solution is very simple. You only need to set it in the system preference settings.

 

3. How can applications on Mac be uninstalled and spam be cleared?

We recommend that you use the cleanmymac tool. You can download the installation package and the registration machine at the following address, which is valid for the test, but does not guarantee that the link is valid for a long time:
