can’t see any tcp/udp/icmp traffic

To see the layer 3+ information in 802.11 captures you need two things, at a minimum:

1. Data frames
2. Decryption capability if the data is encrypted (good practice says it should be...)

For item 2, here is a good link: https://wiki.wireshark.org/HowToDecrypt802.11

I bring up item 1 because it is a common cause of issue when working with wireless packet captures. The data frames tend to go at higher data rates so require better capture capability to match the modulation capabilities of the AP and the client. In particular, I do not see data frames in your picture but do see ACKs. With no more information than this picture, it appears you are not able to capture data frames; however, MAC laptops are known to be excellent capture tools. Something does not look right. You sill have to solve this problem first before working on decryption.

As a test, you may be able to reduce the AP's capabilities so it uses lower data rates and then it will be easier to capture data frames. Otherwise, provide more information on the setup of the system you are analyzing - it could be you are just out of range to capture the high speed frames, etc.

I use this free tool on my MAC to speed up capture setup:
