"No keyboard"
New 2020 MBA. Sporadically, when opening the clam shell, neither the keyboard nor trackpad will work. After about 15-20 seconds, a Bluetooth Setup Assistant dialog appears and says "There isn't a wireless mouse or trackpad connected." 10 second more and the dialog goes away and my keyboad and trackpad start working as normal. 30 seconds too long of a wait though.
I've had this laptop for about 2 months. It happens a couple times per week. Others have reported the exact same problem with the 2020 MBP. See for example https://cfenollosa.com/blog/seven-years-later-i-bought-a-new-macbook-for-the-first-time-i-dont-love-it.html.
I typically keep bluetooth turned off. I thought that might be the problem, but even after re-enabling it, the problem continued to occur.
This must be a sleep-related bug in the OS. Apple, please help.
MacBook Air 13″, macOS 10.15
