I'm having troubles with my client. I use the Mac version, and I tried to update today, only getting an osu.exe error message saying, "Unable to find a version of the runtime to run this application." I tried restarting, and the problem persisted. I checked the logs, and the update log mentions nothing, while runtime says "Initialized" and listed basically all the files in the game for today, likely in the previous session today. Is there a reason that this is happening, and how can it be fixed?
