sorry if this has been posted a million times but i have read a few and tried all suggestions but im stuck.

 

have a Unibody 15" pro with snow leopard. i have got a new hard disk and setting up a new copy of OSX onto the mac.

 

i have partitioned the disk and formatted. tried to install but recieve the error Install Failed: The installer could not copy the necessary support files

 

i have mad an image of the CD onto a usb disk and booted off that but get the same error. the OSX DVD is slightly scuffed so maybe its making a bad image of it? i have tried removing printer support etc. i have also tried another new disk.

 

is there anything else i can try?

i have taken one stick of ram out at random and got past this error now. is it likely the ram is faulty or that the slot is faulty?

 

That's interesting. I was getting the same error. I discovered that one of my RAM sticks was faulty using MemTest86 on my PC. I've sent them back to the manufacturer to be replaced. I'll let you know if I still get the error when I receive my new RAM sticks.

I got my new RAM sticks delivered on Friday. Tried the install process again yesterday and Snow Leopard installed first time.

 

One thing I did differently was to select "Customise" and deselect all additional options at the start of the install wizard.

 

I am now faced with a new problem of my system not detecting the IDE harddrive I installed onto. However, I am pretty sure it's just because it's a really old HDD so I might need to get another one and try again. Still haven't booted into OSX yet.

 

I'll keep you updated.

Funny enough as a HACKINTOSH user i had this same problem.. but now im in middle of doing the install with only 1 stick of ram and it looks to be working i will update to say if complete and how i fixed it if not..

 

this is a little note for hackintosh users.. just because its worked once doesn't mean it will work all the time and if you are using a retail version like me (purchased) then be sure to keep the disk well looked after :)

 

Mordzy thanks for this post i found it on google and it helped a lot !

This post got my machine to work. My HD died and I put in a new one. When I went to load the original image disk it kept stopping after it counted down to 32 minutes. I selected custom and deselected everything, Snow Leopard loaded without a problem, I hooked up my Time machine drive and in an hour my imac looked like it did before it died. Thanks for the tip!
