Remember that the problem can also be a bad cable, so if you plug a peripheral back in and it causes the gray screen issue, try the peripheral with a new cable before you replace the peripheral. Swap your mouse and keyboard with a known good pair, and then restart your Mac.
If you don't have spares, just disconnect them and restart by pressing and holding the power key. If your Mac gets to the login screen or desktop, then you'll need to determine whether the problem is the mouse or the keyboard. Try plugging in one at a time and then restarting to confirm. Start your Mac using the Safe Boot process if no peripheral or cable appears to be at fault.
To do that, first disconnect all of the peripherals, except the mouse and keyboard. During the Safe Boot, your Mac performs a directory check of your startup drive. If the drive directory is intact, the OS continues the startup process by loading only the minimum number of kernel extensions it needs to boot. If your Mac successfully starts up in Safe Boot mode, try restarting your Mac again in normal mode. If your Mac starts and makes it to the login screen or the desktop, then verify that your startup drive is working correctly.
Chances are the drive has some issues that need to be repaired.
You can use Disk Utility's First Aid tools to check and repair your drive; you may even need to replace the drive. For instance, sound levels are set to the default, the internal speakers are set as the source of audio output, and the display options and brightness reset. If it comes on normally, reattach your peripherals one at a time, restarting the Mac after each, to verify that none of them caused the original gray screen issue. Remove all but the minimum amount of RAM from your Mac.
If it does, then one or more pieces of RAM have failed, and you'll need to replace it. However, you should be able to continue working with your Mac until you get the replacement RAM. Unfortunately, we're getting to the point where the troubleshooting steps will likely cause you to lose some, if not all, of the data on your startup drive. So, before we go there, be sure to try this RAM fix first. Repair the startup drive by booting to external media, like an install disk. This verifies if the startup drive is having problems. Start from the Recovery HD :. If at this point you successfully started your Mac but the repair process didn't work, the startup drive may need to be replaced, which involves reinstalling the entire operating system.
If you can't repair your startup drive using Disk Utility, try a third-party drive utility. If you do repair the startup drive, it may need to be replaced in the near future. Boot into single-user mode to repair the startup drive. One of the less well-known special startup modes that a Mac can operate in is known as single-user.
This special startup mode boots the Mac to a screen that displays information about the startup process. The display looks like an old-fashioned terminal from the days of mainframes and time-share computing systems, but it's more akin to the startup sequence in many Unix and Linux operating systems. In fact, many of the same commands are available from the prompt.
When in single-user mode, the Mac doesn't automatically load the GUI, including the Desktop; instead, it stops the boot process after launching the basic OS kernel. Remove or replace the startup drive, or take your Mac to an authorized service center, such as the Genius Bar at an Apple store. If you are unable to start your Mac with any of the methods listed above, you may have a damaged startup drive or another internal component that's preventing your Mac from booting.

The Go Menu in Mac OS X Mountain Lion
Tom Nelson has written hundreds of articles, tutorials, and reviews for Other World Computing and About. Notification Center can be accessed by clicking the icon in the right corner of the menu bar. When open, the user can click a button to tweet , post status updates to Facebook , or view all notifications in the sidebar pane. Swiping up will reveal the option to disable Notification Center for one day.
Each application can have three ways to display notifications: none, banners, and alerts. Options to toggle the app icons and sounds are also available.
Users can click and drag an app in the pane to change the order the applications are displayed within Notification Center. Notes, another transfer from iOS , is added. It is separate from Mail in its own application, with support for desktop notes added syncs along with its iOS counterpart. When the application is closed, the pinned note still remains. Notes can be created in three different default fonts - Noteworthy, Marker Felt, and Helvetica.
Users can add custom fonts by visiting the Show Fonts menu. The menu allows users to change text size, format lists, choose the alignment left, center, justify, or right , assign a writing direction, and indent text. Attachments, images, and hyperlinks can also be added into a note. Attachments cannot be viewed on iOS devices.
Messages, an instant messaging software application , is added in Mountain Lion. As with its predecessor, Messages has text messaging, audio, and screen-sharing capabilities. Messages also contains native video conversation support, utilizing Apple's FaceTime video calling application where possible. However, it does retain video capabilities for interfacing with other instant messaging clients. It also offers a direct connection to Yahoo!
Messenger and Google Talk.
It is an online multiplayer social-gaming network, and allows users to invite friends to play a game, start a multiplayer game through matchmaking, track their achievements, and compare their high scores on a leader board. Players can earn points by meeting specific in-game challenges. Only one nickname may be associated with an Apple ID at any given time. A profile consists of the player's nickname, the number of Game Center-compatible games the player owns, the number of friends the player has, the number of achievement points a player has, and an optional photo and player-defined status.
OS X Mountain Lion added updates for many applications on the operating system. The Chess app supports Game Center. Dashboard widgets can be managed in a UI similar to Launchpad. Reminders is a new to-do list application, separate from Calendar in its own application that syncs along with its iOS counterpart. The address bar also has a "Reader" button, showing the user just the text of the article without advertisements and distraction.
When the user is on a website with no article, the button is disabled. Time Machine is able to do rotating backups on more than one storage medium. Some of the features include single-sign on and integration in Notification Center, Contacts and Share Sheets. Several new screensavers were added. Application updates automatically install from the Mac App Store. The iCloud library User interface UI was integrated throughout the operating systems, which includes new Open and Save dialog boxes across built-in applications, iWork and third-party applications via an Application programming interface API.
Applications that make use of this API support a new user interface to view and manage documents in the cloud that are specific to the application being used. The full screen ability is on every display. The Dock has received an updated look, emulating the appearance of the aluminum metal surface that much of Apple's current hardware line-up sports.

Reception for OS X Mountain Lion has generally been positive, with users considering it to be a major improvement over John Siracusa of Ars Technica said that I'll take Even prerelease builds were far more stable than I've come to expect from OS X betas, leading me to wonder if Apple's new annual schedule is leading to more careful incremental updates with fewer bugs rather than great leaps with more, nastier bugs.
The general attitude towards Mountain Lion was that it was faster and smoother, including Brian Heater of Engadget , who said the following:. Taken as a whole, the features mark a fairly aggressive bid to fold the best of OS X and iOS into one product -- a strategy we first saw with the introduction of the Mac App Store on Snow Leopard, and with the arrival of Launchpad last year in Lion. That said, it seems time for Apple to make a bold new pronouncement on the desktop front.
The company appears to have most of its resources invested in the mobile side -- and there's no question as to why: the iPhone and iPad have reinvigorated the company, making it a computing player on a scale that no one save, perhaps, for Jobs himself could have predicted a decade ago.
Still, it might be hard for OS X users not to feel neglected -- many of the latest new features feel a bit like iOS hand-me-downs. When and if Apple rolls out a new operating system this time next year, hopefully we'll be seeing a very different side of Mac OS. He also praised the application compatibility and said that the only updates needed were to add Notification Center features to applications. All new features? No, not really.
But 10 that you'll use every day? While the operating system in general was well received, some reviewers dissented from that viewpoint. Game Center was the most criticised aspect of Mountain Lion. Reviewers criticized the service for the lack of games available, reliability issues and the lack of integration with iOS games. Mountain Lion sold 3 million units in the first four days, making it Apple's most successful OS X release to date.
