macbook air m1, 13.4 mac os, I have two errors when diagnosing VFD001 and ALS001, the light sensor works fine for me, I checked by changing the lighting, but I can't find true tone in the display settings, I can't turn on true tone, what could be the error, I would like to solve at home?
MacBook Air 13″, macOS 13.4
Hi masterfftg,
Thanks for posting in Apple Support Communities.
Both of the error messages indicate a hardware issue that need to be inspected at the Apple Authorized Service Provider or Apple Store. VFD001 refers to an issue with display or graphics processor. ALS001 indicates an issue with the ambient light sensor. You can find these details and their solution in Apple Diagnostics reference codes - Apple Support.
Regards.
true tone not work
