Can you connect the Kickr v5 to the build in MacBook Pro Bluetooth? Zwiftalizer 2.0 as am getting a lot of drop out
Yes you can. Your ANT+ dropouts may be due to wireless interference or too much distance between the ANT+ receiver and the trainer. Most people use a USB extension cable to move the ANT+ dongle closer to the trainer. Other devices such as cordless phones, baby monitors, microwaves, fans/motors, Bluetooth things, and 2.4GHz WiFi can also interfere with ANT+.
With the Kickr v5 you also have the option of using direct connect (Ethernet to the trainer). For that you would need to buy the Wahoo direct connect device:
I have it on a USB extension behind the front wheel may try a new Ant+ dongle. I may also turn off the Bluetooth on the MacBook see if that help.
You can also try relocating the dongle to various positions around the trainer and uploading logs to Zwiftalizer to see if things improve.
