In general, I haven't had a good experience with Parallels. The big issue for me is related to memory. Every time I use the software, it doesn't matter how much memory is available on my Mac (8, 9, 10, 11GB) and, even without downloading anything, a message about almost full storage space appears. At such times I need to restart the computer. For example, yesterday, with 8GB storage available, I needed to used Notepad to paste something and that message appeared on the screen.So, I have avoided using the software, which is a shame, because, when I started using it, everything was working perfectly.
