can anybody help me on the following, thank you in advance!

• can you use the RTH button on the virtual flight videos? (doesn't seem to work on mine)
• do you need to calibrate the drone as it was compulsory on the Mavic Pro?
• are there any adjustment needed before the first flight
• do I need this: DJI Assistant 2 (DJI FPV series)? I tried to download it on my mac but...where is it? is there a special procedure to install it to a Mac?
