My MacBook won't recognize any HDMI device (I restarted, reconnected on several devices).

Curious how much of the above reference article you were able to use to

troubleshoot; by using any other adapters, cables, &/or external displays.

• Use external monitors with your Mac - Apple Support

• Get help with video issues on external displays connected to your Mac - Apple Support

Between cables, adapters, hubs, Docks; multiple port accessories, etc.

Many choices would need sorted through and some testing done.

Which 'macbook' build model year does yours identify with?

Not sure how you'd go about troubleshooting your situation w/o

additional (and different branded gear?) to work around issues.
