To reset the SMC, shut down your MacBook Air. Once it's powered off, press Shift + Control + Option on the left side of the built-in keyboard, then press the power button at the same time. Hold these keys and the power button for 10 seconds. Release all keys and the power button, then press the power button again to turn on your MacBook Air.
First, ensure the MacBook is charged by connecting it to its power adapter. If it still won't turn on, try resetting the SMC. If the issue persists, try starting in Safe Mode by holding the Shift key during startup. If none of these steps work, contact Apple Support.
To access Recovery Mode, restart your MacBook Air and immediately press and hold Command + R keys until the Apple logo appears. This will boot your Mac into Recovery Mode, where you can access various recovery tools.
Use a soft, lint-free cloth slightly dampened with water to clean the screen. Avoid using window cleaners, household cleaners, aerosol sprays, solvents, alcohol, ammonia, or abrasives.
To check the battery health, click the Apple logo in the top-left corner, select "About This Mac," then click "System Report." In the left sidebar, under "Hardware," select "Power," and you'll find the battery health information under "Battery Information."
No, the RAM on the MacBook Air Retina 13 Inch 2018 is soldered onto the motherboard and cannot be upgraded after purchase.
To perform a factory reset, restart your MacBook Air and hold Command + R to enter Recovery Mode. Select "Disk Utility," then erase your startup disk. Afterwards, exit Disk Utility, and select "Reinstall macOS" to reinstall the operating system.
To improve performance, ensure your macOS is up to date, close unnecessary applications, manage startup programs, clear cache files, and consider upgrading to an SSD if you haven't already.
Use a USB-C to HDMI or USB-C to DisplayPort adapter to connect your MacBook Air to an external monitor. Once connected, go to "System Preferences" > "Displays" to configure the display settings.
If your trackpad is unresponsive, try resetting the SMC. Ensure the macOS is updated to the latest version. If the issue persists, boot into Safe Mode to see if the problem continues, which can help determine if it's a software or hardware issue.
