What if this doesn’t work for you?

To do so, press and hold down the power button for a few seconds until the Mac or MacBook turns off. Wait a few more seconds, then turn it back on.

If you're having trouble logging into your Mac or MacBook after installing macOS Catalina, or you're stuck in a loop where you log in, then get logged out again, the following steps might help. This removes a file, which makes it appear like you're starting Catalina up for the first time. Don't worry, nothing important is getting deleted. Press Enter, then restart your Mac.

Find com. MailServiceAgent and move them, either to Trash or somewhere temporary like your desktop. Empty Trash, then restart your Mac and see if that works. There are reports that the search function no longer works in the Mail app after installing macOS Catalina. The first thing to try, if you encounter this problem, is first close Mail completely. Then hold Shift and click on the Mail icon to open it in Safe Mode.

Then, close Mail again, then hold Shift and open Mail again. Finally, close Mail yet again, then reboot your Mac. Open Mail normally, and search should work again. Reboot the Mac and load up Mail to see if search works. Once macOS Catalina is installed on your Mac or MacBook, you may notice that your device is running slower than before. If macOS Catalina also showed a notification that said "Optimizing Your Mac: Performance and battery life may be affected until completed," then this is normal, as macOS Catalina is doing things behind the scenes which can initially impact performance.

After a day or so, your Mac should be running just as well if not better as before. If you don't see an improvement by then, try restarting your Mac or MacBook. Another thing to check is to make sure that all of your apps and software are updated to the latest version. If any of them have issues with Catalina, that could be slowing down your machine.

I suspect the email composer has been "updated" and is functioning more like Google Docs, which also doesn't support MacOS text replacements. It would be great to get an official work on this. I use text replacements constantly. Loss of this in Gmail is a deal breaker for me. Mike Dauber.
