Just got email notification for an update to Piriform's CC Cleaner, and checked their site to see if there was one for the Mac. And there is! Checked here and don't see anything leaping out at me as to whether or not it is a good idea, functions, whatever. Anybody think CC Cleaner for Mac is. 5 thoughts on “ Fix double login prompts on your Mac ” Strod April 1, 2015 at 4:00 pm. Two comments: First, it is always a good idea to have an alternate admin account configured on your system. That way, if you muck your user’s account to the point where you can no longer log into it, you can still log into the alternate admin and try to fix things from there.

When booting your Mac you should only need to supply your username and password once in order to log in. However, there may be times upon cold-booting your Mac where you enter your password at the login prompt, but after the system shows a gray boot screen as expected, it displays your login window again. This problem does not affect the functionality of your Mac, and is only a minor hiccup in how FileVault disk encryption is set up on your system.

FileVault encrypts your entire disk, including the operating system. When you turn on your Mac, a login screen look-a-like is presented that shows the usernames your system has authorized to unlock the disk. Since these are users on the system, once the disk is unlocked and OS X loads, the login credentials you provided will be passed to the OS so it automatically logs in and does not require you supply the same credentials twice.

The problem here is that these credentials are not being passed to the OS, so the system will first ask for your username and password to unlock the disk, and then do so again to log into the system.

This break in the login process may happen after upgrading your system, especially to Yosemite, where Apple converts your hard drive to a CoreStorage volume (a special volume-management setup that allows for encryption). As part of Yosemite’s setup, you are encouraged to enable FileVault, so this feature may have been enabled by you somewhat in passing. This problem may also have happened when restoring from a backup, reinstalling Yosemite, changing and modifying user accounts, among other core system modifications.

The first approach for fixing this issue requires you toggle your account’s administrator status, especially if you have multiple administrator accounts set up on your system (admin status in Yosemite automatically grants the ability to unlock your hard drive):

1. Go to the Users & Groups system preferences
2. Click the lock to authenticate
3. Ensure an account other than yours is granted admin status
4. Log into that account and demote your current account to Standard
5. Reboot your system for these changes to take effect, if prompted
6. Log into your second admin account and re-enable admin status for your main account
7. Shut down your Mac, and then boot it up to test your login windows

Create a new user account and toggle this option to give it admin status. Then restart your system when prompted.

While this involves a few steps, it is overall the fastest option for addressing this issue. Once completed and if the login window only displays once, you can go back to the Users & Groups system preferences and remove any temporary administrative accounts you had to create for this process.

The second approach for this problem is to disable and re-enable FileVault completely, which will re-associate your administrative accounts to the disk encryption prompt, setting up your Mac to pass the supplied credentials to the operating system when it loads.

1. Go to the Security & Privacy system preferences.
2. Go to the FileVault tab
3. Click the lock and supply admin credentials to unlock the preference pane
4. Click the “Turn Off FileVault…” button
5. Restart your Mac when prompted

Click this button to disable FileVault, followed by restarting. Re-enabling FileVault will associate your admin accounts to unlocking the disk.

The problem with this approach is it may take a while to both decrypt and then re-encrypt the system, but it is perhaps the more thorough method of addressing this issue. Overall, I recommend you try the first approach, and then the second one if the first does not work for you.

The Finder is the first thing that you see when your Mac finishes starting up. It opens automatically and stays open as you use other apps. It includes the Finder menu bar at the top of the screen and the desktop below that. It uses windows and icons to show you the contents of your Mac, iCloud Drive, and other storage devices. It's called the Finder because it helps you to find and organize your files.

Open windows and files

To open a window and see the files on your Mac, switch to the Finder by clicking the Finder icon (pictured above) in the Dock. Switching to the Finder also reveals any Finder windows that might be hidden behind the windows of other apps. You can drag to resize windows and use the buttons to close , minimize , or maximize windows. Learn more about managing windows.

When you see a document, app, or other file that you want to open, just double-click it.

Change how your files are displayed

To change how files are displayed in Finder windows, use the View menu in the menu bar, or the row of buttons at the top of the Finder window. You can view files as icons , in a list , in columns , or in a gallery . And for each view, the View menu provides options to change how items are sorted and arranged, such as by kind, date, or size. Learn more about customizing views.

When you view files in a gallery, you can browse your files visually using large previews, so it's easy to identify images, videos, and all kinds of documents. Gallery View in macOS Mojave even lets you play videos and scroll through multipage documents. Earlier versions of macOS have a similar but less powerful gallery view called Cover Flow .

Use the Preview pane

The Preview pane is available in all views by choosing View > Show Preview from the menu bar. Or press Shift-Command (⌘)-P to quickly show or hide the Preview pane.

macOS Mojave enhances the Preview pane in several ways:

• More information, including detailed metadata, can be shown for each file. This is particularly useful when working with photos and media, because key EXIF data, like camera model and aperture value, are easy to locate. Choose View > Preview Options to control what information the Preview pane can show for the kind of file selected.
• Quick Actions let you easily manage or edit the selected file.

Use Quick Actions in the Preview pane

With Quick Actions in macOS Mojave, you can take actions on a file without opening an app. Quick Actions appear at the bottom of the Preview pane and vary depending on the kind of file selected.

• Rotate an image
• Mark up an image or PDF
• Combine images and PDFs into a single PDF file
• Trim audio and video files

To manage Quick Actions, click More , then choose Customize. macOS Mojave includes a standard set of Quick Actions, but Quick Actions installed by third-party apps also appear here. You can even create your own Quick Actions using Automator.

Use Stacks on your desktop

macOS Mojave introduces Stacks, which lets you automatically organize your desktop into neat stacks of files, so it's easy to keep your desktop tidy and find exactly what you're looking for. Learn more about Stacks.

The sidebar in Finder windows contains shortcuts to AirDrop, commonly used folders, iCloud Drive, devices such your hard drives, and more. Like items in the Dock, items in the sidebar open with just one click.

To change the items in your sidebar, choose Finder > Preferences from the Finder menu bar, then click Sidebar at the top of the preferences window. You can also drag files into or out of the sidebar. Learn more about customizing the sidebar.

Search for files

To search with Spotlight, click the magnifying glass in the menu bar, or press Command–Space bar. Spotlight is similar to Quick Search on iPhone or iPad. Learn more about Spotlight.

To search from a Finder window, use the search field in the corner of the window:

When you select a search result, its location appears at the bottom of the window. To get to this view from Spotlight, choose “Show all in Finder” from the bottom of the Spotlight search results.

In both Spotlight and Finder, you can use advanced searches to narrow your search results.

Delete files

To move a file to the Trash, drag the file to the Trash in the Dock. Or select one or more files and choose File > Move To Trash (Command-Delete).

To remove a file from the Trash, click the Trash to open it, then drag the file out of the Trash. Or select the file and choose File > Put Back.

To delete the files in the Trash, choose File > Empty Trash. The storage space used by those files then becomes available for other files. In macOS Sierra, you can set up your Mac to empty the trash automatically.
