Catalina macOS Promise to bring a lot of fine changes for users of macOS and a better interaction with devices iPad, with the launch of the dedicated system Ipados.
In addition to the good things (many) that we could list about Macos Catalina, the current beta version has some obviously unfinished bugs and things. News like elimination of iTunes, adding applications Apple Music and Apple TV on macos, redesigning applications Reminders and Notes, but also the new features of the application Photos, they also brought some problems for beta tests.
After a clean installation of Macs Catalina Beta on a MacBook Pro 13-inch, Mid. 2012, I noticed a Graduate noise enlargement produced by the cooling fan. At least strange thing for a MacBook, which is very quiet. Be he and an older model.
The noise produced by the fan of a Mac and of a PC is directly proportional to CPU temperature. The more the temperature it rises, the stronger it will turn it to try to bring it to an optimum operating temperature. The temperature of a processor (CPU) increases as it receives processes or services with demanding operations, most of the time over his power. The best way to see which process or service requires the most CPU, is the user Activity Monitor.
We open Activity Monitor, we go to the CPU tab and select "%CPU"In decreasing order.
It was easy to realize that the process ”mstreamd"It is the one that causes a marked heating of the processor.
What is "mstreamd" and why does CPU ask a lot?
Fortunately "mstreamd" is not a virus or malware, but a legitimate process of the Catalina macos operating system. This process is also met on iOS, and the developmental developmental knows it very well. Especially the applications that interact with the IOS photo gallery.
“mstreamd” – Media Stream Daemon, is the process that deals with the management and transport of images and video files from the photo galleries stored on the Apple servers. "Shared Albums"Like many other processes," Mstreamd "is part of the" Photos "native application.
Why does the "MSREAMD" (Media Stream Daemon) require the processor (CPU)?
Most of the time, the CPU overload by this process appears immediately after the installation of the operating system, and in time everything returns to normal. The CPU is requested when the photo gallery was accessed for the first time on a new installed system.
After installing a maccos operating system, it needs the period of "peace" in which to finish the data synchronization in iCloud. The contacts that will be brought in the application "Contacts", Notes, Reminders, Mail, Calendar, files stored in the ICLOUS space and many more.
If during the synchronization period the user forces to open a "Shared Albums" album from the application Photos, then this process will be priority to bring the contents to Mac. To the synchronizations already encountered by default system will be added a large task with the photo gallery. From here there is the problem of overloading the processor. Which leads to Mac heating and a rather annoying noise of the cooling fan - fan.
You can interrupt without problems the "MStreamd" process by double-clicking on it and click on the "quit" barrel → "Force Quit".
After restarting the operating system it will restart and resume its activity.
