It is not a cause for concern if mobileassetd consumes high CPU resources. This process that you see with "high CPU usage" in Activity Monitor is not part of a virus, malware or

The problem data is very simple. On a MacBook Pro (13-inch, mid. 2012) with macOS Catalina, there are times when load CPU exceeded 100%, and this high CPU usage is given by the process "mobileassetd". Although by their nature MacBook and Mac are very quiet calculators, when the CPU exceeds 100%, the sound given by the fans (CPU FAN) cannot be ignored.

In the image below, “mobileassetd”Shows that it uses 78.8% of the CPU, which is not small at all. Not to mention that there were times when he overcame 100% CPU usage.

Fortunately, "mobileassetd" it's not a virus and not even a process that interacts with third-party applications, apart from those developed by Apple for their own systems. “mobileassetd”Was present both on iOS 13 as well as macOS, up to version macOS Catalina.

Why mobileassetd consumes high CPU resources – High CPU Usage?

Normally, "mobileassetd”Is seen running alongside Xcode or other software applications for development, being responsible for downloading and handling data for system applications.

The fact that on macOS Catalina we see a very high load of the CPU in some moments because of this process, we don't have to worry. Most likely this high CPU usage occurs because of the MacBook we have Catalina it has not been open for several days, and in the meantime there have been updates to the archives that need updating. Therefore, this high usage caused by mobileassetd it will be temporary.

If we leave Mac open for a few minutes. without requesting it in other operations, the process "mobileassetdWill reduce its CPU requirements on its own.
