Text color changer disappeared? (Preview app, MacOS 27.2)

Some users have reported a graphics rendering bug introduced in the macOS 27.2 update that affects the Preview toolbar.

Steps to clear the issue:

• Force Quit Preview: Press Cmd + Q, or open the Apple Menu > Force Quit and select Preview. Reopen your document.
• Toggle the Toolbar: Press Shift + Cmd + A twice to quickly hide and unhide the Markup toolbar. This forces macOS to redraw the UI elements.

Personally, I cannot replicate the problem. The color picker is there whenever the text tool button is clicked.

Note that if another graphical element (a drawn line, for example) is selected, then the text button becomes grayed out and not clickable.

Additional troubleshooting steps:

Have you rebooted your Mac? If not, that's the first step. If that does not help, then see if the problem is present when you boot in safe mode. That process performs some system cleanup and clears caches, and also disables 3rd party extensions that may cause problems.

If that does not correct the issue, test in a new user account. A newly-created user account will have all settings at default, and if the issue does not occur in that new account then it provides guidance on what may need to be changed to correct the issue.

Add a user or group on Mac - Apple Support

Once the testing is complete, the new account can easily be deleted.

Those steps will help to isolate the problem.

If the issue occurs in safe mode and a new user account, that suggests a bug. Bugs can be reported to Apple here:

It appears it's just you…

Try restarting. If that doesn't work try booting into Safe Mode then restart normally. Sometimes that will fix anomalies.
