MAC Studio will not let me use Safari to type in comments sections of newspaper

when things are not working right, we often suspect "added software" as the culprit.

the test for that is too run in Safe mode, and try the same activity from safe mode.

"Works in Safe mode, fails in regular mode" implies "It's something you added".

How to use Safe Mode on your Mac

Use safe mode on your Mac - Apple Support

.

Try a different browser to test. Firefox, Edge, Google Chrome, etc. I seriously doubt it is Safari or macOS. Does this issue appear on every website you visit and can enter text? If not then it’s the website, not your software.

<<. I am having a lot of problems with Mac Studio M2 Max and very disappointed. >>

I am really sorry about that.

But unless/until you articulate exactly what those problem are, in substantial detail, Readers here can not do more than say, "That's too bad."

Chrome:

if you want to be running Chrome, provided by a company whose only visible means of support is selling your personal data, you should buy a Chromebook. Chrome on Mac is an Enormous resource hog and crowds out most other things you try to run at the same time.

Downloads:

Your Mac in general and Safari in particular are designed to keep unwanted junk from being downloaded without your EXPLICIT consent. you should be seeing a dialog-box asking if you want to allow downloads from that site. if not, and you want those downloads, you can use this to provide authorization on a site-by-site basis:

Safari > Preferences > WebSites > Downloads

Facebook:

there are many restrictions about what items you can add your comments to. Often, it is only on Users who are "Friends" of groups of which you are a member.

Facebook is unique in the speed at which the interface changes in arbitrary and capricious ways. The pace of user-interface changes on Facebook is unmatched by anything else on the internet. Anything you learned yesterday about how it works will be obsolete by tomorrow. It's NOT your Mac that is doing this.

Yours is the first I’ve heard of this. I certainly have no issues like this on my Mac Studio. And it’s not the hardware, there’s some kind of glitch goin on.

Have you tried starting i safe mode like Mr. Bennet-Alder suggested?
