• Try safe mode if your Mac doesn't finish starting up - Apple Support


This says Yosemite, but information will work on most other OS X:

• OS X Yosemite: If you see a blue screen at startup


There may be a hardware problem with the computer, however that

may be difficult to troubleshoot if you cannot boot from OS X install

system install DVD, to see what it's version of Disk Utility says about

the main hard disk drive. The included Hardware Tests are not a sign

of confidence nor are their results conclusive. (Basically unhelpful.)


• ID Your Mac - iFixit info: (non-portable desktop models)

Would be helpful if you have any information on the build model Mac

and if the unit is a Tower, is aluminum or plastic, what it looks like, etc.


In any event...

Good luck in this matter! 🙂

I think it's a hardware problem


Then we must have the exact Mac model and sub-model. No one here can "use the Force" to see what is wrong unless you fully describe the product and the problem. There are hundreds of Mac computer models and different groups have different troubeshooting steps.


For what it 's worth, all Macs this forum section covers were made prior to 2006 so are all over ten years old.
