I bought my first Mac computer in January of 2020. I taught at a school that used Mac computers and loved them. I also had IPhones and iPad so I was a big familiar with Apple products. My computer worked well at first and soon it became sooooooooo slow. It would take fifteen minutes just to start up. I called Apple Care numerous times trying to fix the problem. In the meantime, I had bought a MacBook Air laptop and used that instead of my desktop computer since it was so slow. On Saturday I tried to install the latest update on my desktop computer. I tried for two and a half days. I finally called Apple Care. Since I have all my files backed up to Backblaze, we decided it was best to wipe my hard drive clean and then install the latest update. I feel like I have a new computer! I can't believe how fast it is now!
