There is a bug I discovered and I have verified with others that was present from the beginning of Sequoia, which has not been corrected in any update up to 15.4.1, to which I'm about to update. The bug is, if in Finder, you highlight the title of a file by double clicking it, and then click the Edit button in the top menu bar, then choose Copy from the drop-down menu, unless you have just restarted your MacBook, "Copy" will be followed by the name of a file, but it will not be the file you have highlighted and are about to copy, it will be a previous file, either directly previously copied or sometimes several copies before. However, if you do copy that way the file title highlighted will be properly copied. The proper function should be that there is no title following the word "Copy", as when you do a right click and copy something from the drop-down menu, or how it has been from the top menu in all previous OS before Sequoia. Showing the title of file should only occur from the top menu bar if you click on the file once to select it with that highlighting the text, after which you can copy the entire file, not just the text of the title. This persistence of a file title in the Copy button from the Edit function of the top menu bar, in my opinion, can be a security issue if someone is using your computer and they see the name of a previous file copied that may have been private (no one else uses my computer so that particular issue is not concerned for me, but it's the principle). I have had titles persist in that copy button even after I deleted the original file it came from. I pointed this out to Apple several times even filing a bug report but they told me they didn't consider it a security issue. Nonetheless, it is a bug that has not been fixed. I hope it will be fixed in the next OS.
