I recently switched to a Mac, and I had no problem on Windows with this.
Basically I would screenshot lecture slides, copy them then paste them onto the cards, but on the macbook, once I copy something I typed within Anki, then the copy & paste of my screenshots won’t work and it will keep pasting what I have previously copied on Anki. I have to restart Anki to fix this.
Is this a macbook problem that several people have? It’s really bugging me. Thanks.
