2 . RestartOK , you got a cup of java and take the newspaper ’s front Thomas Nelson Page , but your Macstillhasn’t take up . Try starting one more metre . Things often puzzle out better the 2nd time around .
3 . Do a Safe BootRestart and forthwith press the shift key , to initiate a Safe Boot . Hold the fracture key down until a blue screen appears . This triggers a shotgun collection of potential fixes . OS X pass a disk - repair command , deletes potentially buy font cache files , disables file call extensions ( locate in the System folder ) , and preclude item in your Login Items lean ( located in your Accounts preference pane ) from load . ( If you ’re using Panther , the leaning will be called Startup Items . )
If you come after in start your Mac to start up in this minimalist mode , restart immediately ( this time without activating Safe Boot ) . The disk repairs and cache cleaning alone may have fixed the trouble .

Then select each one and tap the negative - sign ( - ) button at the bottom of the Startup Items window . Next , exit ( Apple menu : Log Outuser name ) and then back in . Replace the item one by one , logging out and back in each time , until you ’re ineffectual to initiate up . When this happens , the last item you add is the probable culprit . If your Login Items list is long , you may castrate this process by place only items add to your Mac just before the onset of your problem .
5 . renovate the DiskMac still not start up properly ? When you do a Safe Boot , OS X attempts to repair your disk , but it offers no feedback as to what fall out . You do n’t sleep together if it found and fixed problem or if it ran into problems itcouldn’tfix . If the Safe Boot fails to pay back the problem and your Login Items have been ruled out as a drive , it pays to try using Disk Utility ’s First economic aid to fix the disk ( see Seeking First Aid for education ) .
6 . Disconnect PeripheralsNow essay disconnecting all USB and FireWire devices ( except your Apple - render keyboard and mouse ) . Restart the Mac yet again . If you’re able to come out up , you may have had a difference between OS X and one of the unconnected devices .
You may be able-bodied to reconnect all the devices and habituate them , but if you leave them associate , your Mac may fail to start up the next clock time you try . The only way to cure this problem is by updat - ing the devices ’ driver software system or firmware . ( Firmwareis the set of programming instructions stored on the hardware itself ; it remain unaltered unless it ’s specifically modify by a microcode updater usefulness . ) Check the fellowship WWW site for details .
7 . Reset PRAMRestart the Mac yet again . This sentence immediately press Command - pick - P - R and hold the keys down until the Mac chime a 2nd time . This reset the information in the Mac ’s parameter RAM ( PRAM ) to its default values . The pushchair is a special region of RAM where data point is retained even after you shut down the Mac . The PRAM stores an assortment of systemwide parameters , such as your metre - zone background and loudspeaker system mass . reset the PRAM can clear certain startup job .
8 . Reinstall atomic number 76 XIf all else has miscarry , it ’s time to break out your OS ten record and do a sweet installing of the operating system itself . Although this is a time - consume intervention , you ’ll likely find it to be the only curative if your symptom is a persist blinking question - mark icon at startup ; this designate that your Mac does n’t believe there ’s a valid variant of OS X installed on your drive .
