Uploading photos is another story altogether. You can, however, go to on any computer and log in to your account to view and comment on photos. There is not an Instagram app for posting photos to Instagram from your Mac. Unfortunately, it’s not as straightforward as using the mobile app, but once you get the steps down, it almost becomes second nature. One of those workarounds involves sharing your photos to Instagram from your Mac. Photographers who shoot with cameras have always been at a disadvantage - having to use an array of workarounds to edit photos on their computers before sharing them to a mobile device. They have always been dedicated to being an app exclusively for mobile devices. You’ve got to give Instagram credit for staying the course.
