So far, "Pro Video Formats" version 2.0.1 has installed itself four times on my iMac in the last two days. For some reason, the iMac doesn't seem to know/understand that this software update is already installed. Suggestions on how I can tell the Mac this was installed? (I've tried rebooting, etc.) Thanks, - m P.S This update issue is sort of like, but not as bad as, my Windows VM where updates routinely fail for no good reason.
