[ Insta help ] Bulk Account Creation + Bulk Log In + Bulk Upload

Hi all,

I’m a new BHW user. I’m interested in managing Instagram accounts in bulk.
However, many software/apps mentioned in previous BHW threads have almost become infeasible/old tricks which don’t work now. I use Macbook OS btw. 3 aspects I want to learn:

(1) [ Bulk account creation ] software/apps
(2) [ Bulk account log in] software/apps
(3) [ Bulk account photo upload ] software/apps

Can anyone suggest viable software/apps of 3 aspects above? The more the better.

Many thanks :)
