@Zunbileg On a Mac it’s basically the same idea as profiles, Apple just calls them user accounts.

If you want a separate space for work, gaming, or someone else in the house, go to System Settings then Users and Groups. Hit the little add button, pick the type of account, give it a name and password, and you’re done.

Each account stays completely separate, so it’s a simple way to keep things organized.

@Ellafe Here’s a clean, genuine, to the point reply:

I’ve run into this with Opera before. In my case it was just the browser getting stuck. Clearing the cache and opening wp admin in a private window fixed it instantly. If that doesn’t work, try turning off Opera’s built in ad blocker because it can block some WordPress login scripts. Usually one of these three solves it.
