Activity monitor mac viurs reddit9/10/2023 ![]() It is worth noting that all known versions of this malware family are already detected and blocked by Jamf Protect, which also informs admins if Gatekeeper is disabled on any managed devices. (Certainly, the platform has become more attractive to attackers.) That may make Macs an even more attractive target for crypto mining malware. The researchers speculate such attacks may become more prevalent, in part because of Apple’s success with creating computationally powerful Apple Silicon chips. Following the money, chasing the processors ![]() They found that almost every pirated app shared by the particular user hosted crypto-mining malware. In this case, researchers were able to identify the Pirate Bay account that distributed the files. “Adware has traditionally been the most widespread type of macOS malware, but cryptojacking, a stealthy and large-scale crypto-mining scheme, is becoming increasingly prevalent,” Jamf warned in a extensive report today explaining the attack. The malware is also intelligently designed to evade detection - when a user opens Activity Monitor to see if something is amiss on their Mac, it immediately ceases activity to avoid being spotted. And finally, stay up to date with the latest version of Big Sur or Monterey, as a fix will hopefully arrive soon.Once installed, the malware secretly mines cryptocurrency using the infected Macs. Running that periodically will help keep your resources available. You can also use a third-party memory cleaner that lets you quickly clear RAM. As I said, keep Activity Monitor open, and when you see an app’s memory usage creeping up, address it. In the meantime, there are a few ways to mitigate the issue. The memory bug is an actual issue that needs to be fixed as soon as possible. That’s what happened with the excessive SSD usage earlier this year, though that Apple says that was a “data reporting error” and not an actual problem. We’ve reached out to Apple for comment but haven’t heard back, and it’s entirely possible that Apple fixes it in a future version of macOS without ever addressing the issue publicly. Maybe now that it’s more of a widespread issue, Apple will figure it out. Safari sites spiking memory use happen on a regular basis. On other systems, the data has to be copied from one portion of memory to another-but on the M1, it’s just instantly accessible.” Even better, because all the aspects of the processor can access all of the system memory, there’s no performance hit when the graphics cores need to access something that was previously being accessed by a processor core. ![]() ![]() If it needs more memory for the Neural Engine, likewise. If the system needs more memory for graphics, it can allocate that. The M1 Pro and M1 Max come with higher memory options, but the M1 tops out at 16GB and that’s that.Īs Jason Snell wrote back when the M1 was released, that tidy system has benefits: “The M1 processor’s memory is a single pool that’s accessible by any portion of the processor. As in the iPhone and iPad, the memory was now affixed on the same package as the system-on-chip. When the M1 chip was released, Apple changed the way we think of RAM on our Macs. Perhaps it’s because developers tend to be more hyper-aware of things like this or it’s exacerbated by the extra RAM in the new MacBook Pro, but the number of people experiencing this issue appears to be growing. That leads me to believe it’s a bigger problem that wasn’t as widely reported until now. That’s extremely similar to the MacBook Pro and Monterey issues I’ve read this week-except I’m still running Big Sur. Activity Monitor often shows my memory pressure in the red. ![]()
