A couple of days ago, we echoed a curious news and that I put in evidence again, once again, to those in charge of reviewing each and every one of the applications and the corresponding updates of the applications available both in the Mac App Store and in the App Store.
Apple removed the Calendar 2 application from the Mac App Store, after checking how did not strictly comply with the rules that developers have to comply with when creating applications for their ecosystems, but later more reasons were published that justified this decision: the mining of cryptocurrencies in the background.
One of the latest updates to the Calendar 2 application, which by the way is now available again on the Mac App Store After having eliminated the cryptocurrency mining, it included the possibility of being able to access the premium functions it offers, allowing the application to be in charge of mining cryptocurrencies in the background, a mining that had an impact on the consumption of the battery (one of the stricter Apple standards) due to increased processor performance by 10-20%.
According to the developer of this application, in just three days that option was available, earned a $ 2.000 income from the Monero cryptocurrency. If this option had been available since it arrived on the Apple App Store 7 years ago, it could have earned more than $ 700.000 in revenue.
To try to calm the waters a bit, Calendar 2 developer Magarshak states that will invest all that money in improving the operation and adding new functions to the application. The negligence of the supervisors of the applications and updates of the existing applications in the Mac App Store give us pause, since this application may not be the only one dedicated to mining cryptocurrencies in the background, although it is likely that are reviewing all the applications whose processor consumption is higher than it really should have.
In addition, it is also a warning, for all those who install applications from outside the Mac App Store, where they can sneak us applications that are dedicated to this type of activity, since there is no official supervisor that can control it, beyond the native option of macOS that does not allow us to install applications from unofficial developers, a limitation that can be skipped without any problem.
