Since Tahoe, Keyboard often misses first character.

The first character typed sometimes doesn't show if I haven't typed for about 10 minutes. WIRED keyboards as well as wireless. "Slow Keys" in Settings is NOT turned on.


This never happened before i switched to OSX26. Nothing else has changed.


This was covered here many years ago (15 years+ on the forum) when many people reported it then. I haven't experienced this since that time.

See if the problem is present when you boot in safe mode, which disables 3rd party extensions and performs some system cleanup.

It is possible there are processes running in the background that are using significant resources. Check Activity Monitor, CPU tab, sort by % CPU to see what's running hard.
