I was able to mirror my older MacBook to my new iPad, but I was not able to control my MacBook with my IPad. My MacBook has a broken screen and I have to connect it to an external monitor. I was hoping I could just keep it closed and plug it into my iPad to see and control it. Unfortunately it didn’t work, maybe if I connected it a different way? I connected from my MacBooks USB-A to my IPads USB-C. Maybe if I went from MacBooks Thunderbolt(mini display port) to IPads USB-C (if that’s possible) would I get better results? I don’t have chords/adaptors for that, don’t want to spend money unless I know it will work. I tried tweaking what is mirrored on my computer, that was a mistake, fixing things afterwards is too complicated to explain, but I’m not pleased. I just keep thinking, if I had bought that computer a few months later, I would be able to use side car and I wouldn’t have to deal with the useless third party apps.
