I then uninstalled Malwarebytes and Avast and restarted my MacBook Pro. That did not resolve the Mail Preferences opening issue. Okay - I followed your instructions in your post above (leroydouglas) without having removed the "Cleaners/Optimizers/Anti-Virus" third-party apps. The next step will be to restart the Mac and testĪfter the computer is restarted, open the Mail.app> Preferences to see if it opens properly. Do not move the new folder from this current location. Then Control click (right-click) and choose "New Folder with Selection”. Highlight all the contents in this folder. I do not know if this will sort your issue or not, but it is simple enough to try, with little down sideįrom the Finder>Go>Go to Folder, copy & Paste: Uninstall all third party apps that are Cleaners/Optimizers/Anti-Virus No preferences, no sound in Notifications, no notifications what so ever for mail. I have seen several issues report with Mac's Mail.app after up grade. I found an older forum post ( ) which attempted many fixes and/or workarounds to no avail and the post has gone dormant due to inactivity. Today, after the reinstall of Big Sur, after about 13 minutes Mail opened up (no longer frozen), but Preferences was never opened. The other day (prior to the reinstall of the Big Sur OS) it took about 10 minutes for Mail's Preferences to finally open, while I worked in other apps. I get the spinning "beach ball" while it attempts to open Preferences - while the Mail app remains frozen. : )Īfter installing Big Sur (Version 11.0.1), and again redownloading / installing it to fix Notice sounds - the reinstall of Big Sur fixed the Notice sounds, but not the issue I'm having with the Mail app failing to open Mail Preferences. Maybe after the install (and reinstall) of Big Sur, Mail has to reconfigure / rebuild something about Preferences - and once it has completed that task, it's good to go (until any possible reinstall of Big Sur again). Upon clicking to open Preferences again, it opened immediately. Today, after the reinstall of Big Sur, after about 13 minutes Mail opened up (no longer frozen), but Preferences did not appear. After installing Big Sur (Version 11.0.1), and again redownloading / installing it to fix Notice sounds - the reinstall of Big Sur fixed the Notice sounds, but not the issue I'm having with the Mail app failing to open Mail Preferences.
