Solving Slow Charging Speeds on Ubuntu for MacBook Air 2017

Checking the Hardware

The first step is to ensure that the hardware is functioning correctly. Perform a basic hardware check by:

1. Checking the charging cable and adapter for any signs of damage.
2. Testing the charging cable and adapter on another device to rule out any issues with the hardware itself.
3. Updating the BIOS and SMC firmware on your MacBook Air 2017.

Configuring Power Management Settings

Incorrect power management settings can lead to slow charging. To configure power management settings:

1. Open the Terminal by pressing Ctrl + Alt + T.
2. Type sudo gedit /etc/default/grub and press Enter.
3. Locate the line that starts with GRUB_CMDLINE_LINUX_DEFAULT and add i915.i915_enable_rc6=1 to it. Save and close the file.
4. Run sudo update-grub to apply the changes.

Checking the Power Supply

The power supply may not be delivering the required power to the laptop. To check the power supply:

1. Use the acpi command in the Terminal to check the battery and power supply status.
2. Check the system logs for any power-related issues using the journalctl command.

Updating the Kernel

An outdated kernel can cause slow charging. To update the kernel:

1. Open the Terminal and type sudo apt update.
2. Type sudo apt upgrade linux-image-generic and press Enter.

Installing Additional Drivers

Installing additional drivers can help improve charging performance. To install additional drivers:

1. Install the intel-microcode package by typing sudo apt install intel-microcode in the Terminal.
2. Install the linux-firmware package by typing sudo apt install linux-firmware in the Terminal.

If you've followed the steps outlined above and are still experiencing slow charging speeds on your Ubuntu installation on MacBook Air 2017, consider consulting a professional for further assistance.
