The core macOS process sits in between the programs you run and their graphical manifestation you see on the display. It is also defined as a compositing engine responsible for reflecting application behavior on the Mac’s screen. First things first, here is some wiki stuff on this matter: WindowServer is a collection of services tasked with window management. So, what is WindowServer on a Mac? And why does its CPU usage occasionally skyrocket? Let’s try to figure out. It’s worth mentioning that the WindowServer related bug is often observed alongside unproportioned CPU consumption by the following processes: nsurlsessiond, mdnsresponder, mds_stores, hidd, trustd, photoanalysisd, gamecontrollerd and syslogd. This bug doesn’t appear to survive Mac reboots, but this measure has a short-time effect and the issue eventually re-emerges. In many cases, this drag co-occurs with abnormally high memory consumption. Many users who run into such a situation and open the Activity Monitor to do some reconnaissance discover that a process named WindowServer is constantly using up most of the CPU resources.
But what if the performance of a brand-new or recently released MacBook, iMac, Mac Pro is running slower than usual? This condition requires some insight into the whys.
If the machine’s hardware is upgradeable, one decent workaround is to install more RAM and replace the standard “spinning” storage media with a faster SSD drive. Slowdown issues are a natural upshot of a Mac starting to age and lacking the resources to support increasingly resource-intensive applications. Use the tool to remove the infection if found. Scan your Mac with Combo Cleaner to detect all files related to the malware. Serious Mac performance hit, kernel panics, random reboots

If you have any problems, please post a message on the SourceForge Serial Port Notifier Forums.Mac adware, potentially unwanted application (PUA) Serial Port Notifier can be downloaded from the project’s SourceForge page. A custom label can be added to a port, making it easier to identify. The Launcher dialog allowing new launchers to be defined. The settings dialog showing multiple defined launchers. Programs can be quickly launched using the selected port. Right-clicking on the tray icon brings up a list of serial ports in the order that they were added. A notification message is displayed when a port is added or removed. Custom labels can also be added to ports to allow for easy identification.
Program launchers can be defined that allow programs to be quickly started using the selected serial port. This saves having to navigate to Device Manager to figure out what’s been plugged in. When a port is added or removed, a notification is shown containing the COM port name, allowing you to easily keep track of what’s been plugged in and out. Serial Port Notifier (formerly Serial Port Monitor) is a utility that sits in your notification tray and monitors the serial ports on your computer.
