I copied the latest (April 18th) Raspbian lite image to a 32 GB SD card with Imager. Then I created an empty ssh file and the wpa_supplicant.conf file with ssid and psk as I use them on my laptop. After booting the pi I tried to ping (from Mac or Linux) it but:

ping: cannot resolve pi@raspberrypi.local: Unknown host

Here the file:

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=DE

network={
 ssid="myNet"
 psk="xxx"
}

What could be missing? Thanks for any help

If you can log on to the Pi, try executing this command:

rfkill list all

You may see something like this:

0: phy0: Wireless LAN

  Soft blocked: yes

  Hard blocked: no

1: hci0: Bluetooth

  Soft blocked: yes

  Hard blocked: no

A hard block is caused by a hardware switch, which I don't think the Pi has. A soft block can be removed with:

rfkill unblock wifi

This worked for me, even after a reboot. I got the hint from https://askubuntu.com/questions/566799/wifi-soft-blocked-by-rfkill-on-startup

I found out that model B+ V 1.2 doesn't have a WIFI chip
