The new miner has been using much higher percentages. Developers programmed the miner to use 10 percent to 20 percent of a Mac's computing power, depending on whether the machine was plugged in. The second bug caused the miner to consume more resources than planned. The first flaw caused the miner to run indefinitely, even when users changed the default setting. In an email, Qbix founder Gregory Magarshak said the rollout of the currency miner has been complicated by two bugs that prevented it from working as intended. Patrick Wardle, a researcher specializing in macOS security, has a detailed analysis of the miner here. Almost 24 hours after Ars alerted them to app, it remained available for download.
