It's private for a reason and you should respect that. You have to add them as a friend, otherwise if there were anyway for Mac it would be creepy. I'm not sure if there's a setting to have it always private or not even if friended so I think you're out of luck.
How do you view a private Facebook profile or photo? The only program I see is for a PC and I use a Mac
Bad news for you, no matter what device you're using, none of those "Facebook private profile viewers" actually work, Not only do they not work, but they're also a really bad idea.
Here's a few reasons you'd want to forget about private facebook profile or photo viewers for Mac, PC, or even Android, WIndows Phone, or iOS.
- It's just plain creepy.
- Hacking is illegal.
- If a hacker created software that illegally accesses private information from Facebook, what makes you think that software won't also be spying on you? After all, the Facebook hack would be violating a public network, but the software is actually downloaded to your machine, where it can access much more personal stuff such as all the files on your computer, your browsing history, or even your bank or credit card details.
In light of all that, I'd say it's probably easier to just man up and send the friend request.
Or if you don't get one accepted, leave it at that and move on!
