As a long time user of Mac - more than 10 years, actually - I can confirm this is true.
What is not known, though, is that this also works for some of the users registered in Steemit (Apple being a hidden angel investor in the platform). There is only caveat, though, you need to have at least 10 consecutive comments like the following ones, during the last 10 days:
- cool post, bro
- nice, upvoted, pls upvote me
- followed you, do you follow me back?
- good one, sir, resteemd
- nice article, upvoted
If you qualify, then good luck mining. Do come back and share your results.
I'm a serial entrepreneur, blogger and ultrarunner. You can find me mainly on my blog at Dragos Roua where I write about productivity, business, relationships and running. Here on Steemit you may stay updated by following me
