You should not need to reboot the Mac to see the difference.įor an added customization bonus, don’t forget you can add a message to the login screen of OS X too, this is a good place to put an ownership note or message, maybe even a phone number or email address to signify who owns the specific Mac. Your newly customized background login screen image will be set and you’ll see it upon the new login screen again, you will see this image when you log a user out, boot into the new login screen, or lock the screen to a login authentication window.

Close the /Library/Caches/ folder and log out of the current user account to see the change.

Now copy the version of your custom wallpaper named “.png” from the Desktop into the /Library/Caches/ folder.Locate the file named “.png”, select it, and hit Command+D to make a copy or drag it somewhere like your user folder and make a copy that way (this will serve as a backup of the default login screen background image – do not skip this).Now go to the Finder of OS X, and hit Command+Shift+G, enter the following path in Go To Folder:.Pull down the “File” menu and choose “Save As”, select PNG as the format, and name the file “.png” – save it to somewhere like the Desktop for easy access.Open the image you want to set as the login wallpaper into Preview app of OS X.Whatever image you wish to set as the login background must be a PNG file, and it should be at least the size of your screen resolution if not larger.

If not, I doubt anything would go wrong with the full installer for us, but we should back up our systems anyway ahead of that.Setting a unique login wallpaper this way is easily done and easily undone too. So I assume we’ll get normal updates into that version sometime next week or the week after. Nowhere other than this thread, including in Apple’s own developer forums, have I heard anyone even hint that the previews can’t be upgraded out to the released version.

Even if we aren’t able to simply/even automatically update to the released version using the Software Update functionality, there’s nothing that would stop us from downloading and installing the final OS X 10.10.0 release like any other system upgrade, it would just be over an earlier Yosemite release rather than over Mavericks.

Such an update would be evident to us all ahead of public release because the version that will be shipped publicly, and we ought to see as a simple update, won’t have the letters at the end of the build number. I haven’t heard anything specific (I have GM 2 installed right now), but it seems odd to me that Apple would not enable both Dev Preview (let’s say “a” users based on build numbering) and Public Beta (or “b” users) Macs to get the same delta update to the released (or soon to be released, perhaps, as they’d do well to let us use it for at least a few days prior to unleashing it to the public, just in case severe issues come up) version of Yosemite.
