Man, I hate this crap.
My mouse died ( the cute white one that goes "click" when you push in it, not the gray one that craps in the dog food bowl.)
So I went to order a new mouse and lo and behold Apple has a better one - Magic Mouse 2. Like an idiot I fell for it.
Upon opening the box and reading the instructions I learned that the OS on my Mac won't properly recognize the Magic Mouse 2. I have to upgrade the OS or send the mouse back. Like and idiot I opted to "upgrade." Took an hour, frustrating but it will all be over soon.
But wait! It seems half a dozen of my apps that are not compatible with Sierra - one of them being the encryption app that holds all my passwords. The solution is to upgrade the encryption app. All I have to do is decrypt my files so they can be reencrypted by the new improved encryption app that is compatible with Sierra but not compatible with its own previous version (!!) The new app is so improved that it won't even read the old version's files. The solution - reload the old OS so the old encryption app will run and allow be to decrypt the files. All I need to do is download Yosemite and ... wait. I need my Apple ID password to access the app store and I don't know it. Wouldn't be a problem except it is stored in an encrypted file. Which I can no longer get to.
So at this point, 4 hours after I opened my shiny new mouse, I've changed my Apple ID password and now I'm sitting here picking my nose while the old OS downloads. Presumably, once the OS is restored I can use my Timemachine backup from 11 AM this morning to restore my computer, decrypt my password files, redownload Sierra and install it (about an hour & fifteen minutes), upgrade my encryption app, and re-encript my password files.
I am hopeful, but not confident, that the mouse will work then. It better be a damn fine mouse.
