Also disappointed
I didn’t do my homework, and wrongly assumed that iPhone 5S and Macbook Pro can see each other using Bluetooth. The only way this can work is by connecting the devices using a Personal Hotspot connection (kinda defeats the purpose, doesn’t it?). Even when I did this ridiculousness, Instashare crashed on most file share attempts. I have been unsuccessful in simply putting both devices on the same Wifi network to enable file sharing. Wasted alot of time and effort. Until Apple can fix the glitch regarding Bluetooth sharing between iPhone and Macbook, this app really has no utility.
