Microsoft posted a notice on Wednesday about the accidental posting of a security update for MS Office for Mac.
The post says, in part, "As soon as we discovered the error, we moved quickly to address it and remove the pre-release binaries from our public sites. Once our investigation into this issue is complete and we have security updates that meet our quality bar for release, we?ll release those final security updates for all products affected along with a security bulletin.? We?re also taking steps to ensure a mistake like this doesn?t happen again."
Microsoft recommends that anyone who has installed the pre-release update uninstall it.
