I want to know if there are ways to identify the cause of the delay and lags in cursor when I use the mouse and Magic Pad. Any tools or indicators on Mac to monitor to see the root causes?
I’m using Mac mini with a Logitech mouse and a Magic Pad, connecting to the Mac with unifying (wireless USB transmitter) and Bluetooth respectively.
I don’t think the CPU and the memory are the issue. According to the activity monitor, the CPU idle is usually at 80%, and the memory still not busy.
By the way, I feel the lag after upgrading to MacOS Mojave.
--Answer for my situation-- With some investigation, I found that the cause might be that I had a poor USB connector. According to the thread, some USB connectors disturb the network of Wifi 2.4GHz and Bluetooth devices. After removing the connector, I haven't experience the problem so far.
