Today I tried to open a VMware fusion virtual machine on my mac. Last time I had used it is more than 8 month ago. As far as I can remember, everything worked flawlessly at the time and I can’t remember upgrading VMware since. But today it complained: “VMware Fusion cannot connect to the virtual machine. Make sure you have rights to run the program and to access all directories it uses and rights to access all directories for temporary files.” Bugger.
Some forum thread on the offcial website suggests to reinstall the software. That obviously sucks. The working solution I found elsewhere is much simpler:
sudo /Library/Application\ Support/VMware\ Fusion/boot.sh --restart
