After updating to Catalina, Mac Mini 2018 does not send any HDMI signal.
It was working fine today, until the Catalina update.
Can not enter safe mode nor recovery mode.
Tried resetting NVRAM, no change.
Just in case, I tried another cable and I also tried connecting it to AVR, but still no signal.
Mini is connected to 4K TV, I don’t have any other option (except USB-C to HDMI adapter which I don’t have).
Mac mini 2018 or later
This worked for me, too - after trying all the other suggested fixes in this thread
Same here. Updated to 10.15.2, but same issue as before.
Screen is black when booting and „blind typing password“ is still a thing. Meanwhile I get used to it. 🙄
How can I get my firmware version?
OMFG...... This got fixed with 10.15.1, then yesterday I stupidly updated to 10.15.2 and NO MORE HDMI!!
WTF Apple? Seriously, this is freaking ridiculous!
In the end, I bought an HDMI/USB-C adapter with 4K support
No HDMI signal after update
