1. Charger Compatibility Issues

It’s essential to use a genuine Apple charger that is compatible with your MacBook model. Using counterfeit or third-party chargers may lead to compatibility issues and cause the charger LED light to blink green. To ensure compatibility, follow these steps:

  1. Check the charger’s power rating: Ensure that the power rating of the charger matches the requirements of your MacBook. This information can usually be found on the charger itself or in the MacBook’s user manual.
  2. Inspect the charger’s connector: Make sure the charger’s connector is clean and free from any debris or damage. If you notice any issues, such as bent pins or frayed cables, consider replacing the charger.
  3. Verify the charger’s authenticity: Counterfeit chargers may not meet Apple’s quality standards, leading to compatibility issues. Purchase replacement chargers from authorized Apple retailers to guarantee authenticity.

2. MacBook Hardware Issues

If your MacBook has any hardware issues, it may prevent the charger from functioning correctly. Here are some steps you can take to troubleshoot potential MacBook hardware issues:

  1. Check the charging port: Inspect the charging port on your MacBook for any signs of damage, dust, or debris. Use a soft brush or clean cloth to remove any foreign objects gently.
  2. Reset the System Management Controller (SMC): Resetting the SMC can sometimes resolve charging-related issues. To do this, shut down your MacBook, then press and hold the Shift + Control + Option + Power buttons simultaneously for about ten seconds. Release the keys and turn on your MacBook.
  3. Test a different charger: If possible, try charging your MacBook with a different compatible charger. This will help determine whether the issue lies with your charger or your MacBook.
