Not the commenter but macOS regularly spams people with: - Ads to try Apple Music free for a month. - Ads to try News+ - Ads to try Fitness+ - Try Safari (if it’s not your default browser) - Try/log into iCloud if you’re not logged into iCloud. - Try the latest macOS release if you aren’t on it. As an aside, you do not want to even log into the Mac App Store with a personal account on a work computer. Logging into just the Mac App Store effectively logs you into your iCloud on that machine and sensitive personal data is then strewn across various files under ~/Library. The iCloud sysprefs will claim you are not logged into iCloud but ~/Library will show you the truth.
