In the event that conceivable attempt to use an alternate show, or an alternate connector (use DVI rather than VGA, for instance).
Apple at that point encourages users to take a stab at resetting the PRAM or beginning up in Safe Mode and modifying the determination in System Preferences. (Both of these means are canvassed additionally down in this article).
Like any PC, a Mac is inclined to significant issues through the span of its life. A wide assortment of things can turn out badly. From a total inability to begin to that alarming piece freeze screen, here’s the way to investigate (and ideally fix) what’s tormenting your Mac.
Generally, the issues you run into on a Mac are truly widespread over all adaptations of OS X, however we’ll adhere to the most present day working frameworks here: Lion and Mountain Lion (the greater part of these tips ought to likewise work with Snow Leopard however). In case regardless you’re secured by Apple’s guarantee or AppleCare, the simplest arrangement is to stroll into the Apple Store and have them fix everything for nothing. On the off chance that you would prefer not to sit around idly or you’re not secured any longer, you can do a ton of the investigating yourself.
The Problem: Blue or Gray Screen on Startup
When you turn on your PC and get a dim or blue screen (or it stalls out at the Apple logo) that never stacks OS X, it’s a quite decent cause for concern. This can occur for various reasons, so it’s a standout amongst the most disappointing things that can happen to a Mac, and investigating it is no simple undertaking. Along these lines, how about we separate it into a couple of steps you can take to make sense of what’s happening.
Disconnect All Peripherals
One of the primary driver of a dim or blue screen on startup is contradictory equipment associated with the machine. This may be a printer, an outer hard drive, or even a USB center point. Along these lines, separate everything aside from the mouse and console, and restart your PC.
On the off chance that your Mac begins along these lines, at that point it’s an issue with one of those peripherals.

Safe boot influences your Mac to boot up with the base measure of drivers expected to influence it to work, and it checks your hard disk all the while (it may take somewhat longer to boot up). Do this, start up your PC while holding down the Shift key until the point that the Apple logo passes. On the off chance that your Mac begins up with the protected boot, simply ahead and restart the PC again and check whether it boots up ordinarily (as odd as it sounds this fixes the issue an amazing measure of the time). If not, it’s a great opportunity to give the hard drive a more intensive look.
Run Disk Utility
In the event that despite everything you can’t boot up OS X typically, it’s a great opportunity to run Disk Utility and check out your hard drive:
Boot up your PC while holding down Command+R (in case you’re running Snow Leopard or prior, discover your OS establishment disk, place it in the drive, and reboot your PC holding down C). This will boot you into a demonstrative mode.
- Select the Disk Utility Option.
