FACE A SYSTEM PROBLEM
After upgrading to macos catalina my laptop became working very slowly and also I'm facing a massive problem with hanging once opening folder or document, it takes long time for loading and opening the file or document, also the worst thing that makes me tell you my problem is that as you know because of COVID-19 we are having an online exam, so yesterday I was extremely disappointed because I got zero in my exam due to the suspension of the laptop, however a couple of weeks ago I bought myMac cleaner program which I was thinking will help me to improve my laptop system conversely the application raise the time out. So, can you please help me with this issue, I would be very happy to hear from you.
MacBook Pro 13", macOS 10.15
