I have tried 4 times to upgrade from Sonoma to Sequoia on a Mid 2010 13” MacBook Pro. Each time, it fails and gives me the same dreaded message: “An error occurred while preparing the update”
PRAM/NVRAM reset did not work, tried that twice. Any other suggestions to get this working? I’m racking my brain trying to figure out what else could be the issue. This happens almost every time I do a software update.
