After Upgraded to latest OS Notes search bar is transparent, cursor not visible.

Since Notes accepts the text you type and performs the search, while the typed text and cursor are not visible, first quit Notes with Command-Q, reopen it, and test again. If the problem remains, restart your Mac and test Notes again.

Type some text into a normal note. If text appears normally there but remains invisible only in the search field, that helps narrow the issue to the search field. 

Also test another text-entry field, such as Safari's address/search field or TextEdit.

If you use an external display or display-related accessory, disconnect it temporarily and test Notes using only the Mac's built-in display.

If the problem continues, start your Mac in Safe Mode and test the Notes search field. Safe Mode can help determine whether software that loads during startup is contributing to the issue. 

If necessary, create a temporary user account and test Notes there. 

If the text is visible in the temporary account but not in your normal account, the issue may be specific to your normal account. 

If it occurs in both accounts, it is not specific to that account.

I would not delete Notes preferences or modify your Notes data at this stage. These initial tests do not require those changes.

Finally, check System Settings >> General >> Software Update for any available macOS update. Apple Support — Update macOS on Mac

I am using Golden Gate 27.0  with these setting >> Appearance in Light Mode

Notes search Bar

Because the problem occurs specifically in the Find field within an individual note, rather than the main Notes search, focus on Command-F. 

Apple documents this function by having you open the note, click in the note body, press Command-F, and enter the search text. (Apple Support)

You have already quit and reopened Notes, restarted the Mac multiple times, and reproduced the same behaviour in Safe Mode, so those steps do not need to be repeated.

Open an existing note, click in its body, press Command-F, and type a word that appears in the note. 

Check whether the matching text is still found and highlighted even though the typed characters and cursor remain invisible. 

Then create a new note and perform the same test. Also type normally in the note body to confirm that ordinary text remains visible.

Try Command-F in another application, such as Safari or TextEdit. This provides a comparison with another Find field.

The next useful test is a temporary macOS user account. 

Open a note there and perform the same Command-F test. If the behaviour differs between the two accounts, that result can help narrow down the problem.

For now, avoid deleting Notes preferences, signing out of iCloud, or removing Notes data.

Finally, check System Settings >> General >> Software Update for an available update. 

Apple states that macOS updates also include the built-in Notes app. (Apple Support) 

If no update is available and the problem remains, include these test results when reporting the issue to Apple.

Thanks for testing those steps. Your results are now quite conclusive from a troubleshooting standpoint: the problem occurs specifically with Command-F in an individual note, including a newly created note. It also occurs in Safe Mode and a new macOS user account, while Command-F works normally in Safari and TextEdit. You have also confirmed that macOS is up to date.

At this point, I would not make further changes to your Notes data or iCloud settings.

The results indicate that the behaviour is specific to Notes rather than a particular note, user account, or normal startup environment.

I would report this to Apple as a Notes issue that began after upgrading to macOS 27.0, including these test results and your screenshot. I would avoid calling it definitively a macOS bug until Apple confirms the cause.

I tested all almost.

Quit the notes, restart it but nothing works. then restart Mac multiple times still no change.

see this i typed this in search box which not appearing but it actually select the text and highlight it.

For safemode i tried. When i follow the instructions at the last stage when i ask to type the pass on right top corner i can see red safe mode but after a second it ask me again to type the login screen to type the password after that i cant see the safe mode option.

please note i am talking about invidual notes search not all notes search. the screen shoot is seems like all notes search.

invidual note search seems not working

My software is update to date. I double checked that.

i checked the other application Safari broswer, TextEdit all working fine with command F and text cursor is visible only its not working on nOTEs.

I quite notes and create a new one even its still happening with that.

Tried with new user is having same issue. so seems like it some where bug in new updates.

Hello Dear yesterday got new and first update of this new macOS 27.0 but still notes issue is not fixed. Is that way or work arround to fix that its really annoying while searching or any way i can report to apple as well.
