Apple has released a firmware update for its 140W USB-C Power Adapter. The update upgrades the device from version v1.4.84 to v1.4.90.
The company did not provide a detailed changelog for this release. Typically, such updates are designed to optimize charging behavior, improve power stability, and enhance safety and thermal performance.
The update is delivered via an automatic push mechanism. Users cannot manually trigger the update or track its progress. The process occurs in the background when the adapter is connected to a Mac or other compatible device.
