Using the Sony wi-if transfer is a bit of a hassle. Here is what I do to transfer to my iOS devices.
I first set up the camera to Send to Smartphone and have been using the Select on Smartphone option. With either option you end up at the screen showing the SSID, password, and camera Device Name. Leave that screen on.
I then go into settings for the iOS device and the Wi-Fi setting. Under CHOOSE A NETWORK you should see the SSID name. It may take while or much longer. When it takes too long, I turn off wi-if and turn it back on. That seems to help it some times. I believe you can use Other to manually enter the name. When you see the SSD name tap on it. Enter the password that is displayed on the camera. You iOS device will remember it for next time.
Now open PlayMemories Mobile (PMM) on the iOS device. Depending on what share option you choose either the iOS device will show a list or send chosen files.
After changing the iOS device to connect to the wi-if on the camera, it is likely that your device will appear to continue to search for the camera. I start PMM and often the network connection completes. This is the most flaky part of the setup.
I don't use the Sony Mac software as it wants to do a low level kext install requiring an administrator password. I don't trust Sony software on my computers given their history of adding crap that they should not.
