Good afternoon,

A friend has tried to download Yosemite onto a quite old Macbook and her computer seems stuck on the Yosemite install screen and she can't access her usual desktop. Disc utility repair says it can't repair and connecting to another computer to try to save her files doesn't work - is it a lost cause?

Someone at the Apple Store may be able to see if the user account in the old computer can be

accessed (Target Disk Mode) and some of those old Libraries such as iPhoto, may transfer.


There is a migration assistant that could try & move files and content from an external drive or

a backup on an external; or perhaps from a computer that is booted into Target Disk Mode

where it may be seen by another computer as an external storage drive.


Was the Snow Leopard install-restore DVD used to see if an archive and install could be done

and a new system put into the old computer, in a way that does not erase the content? If the

original hard drive is worn or failing, that could contribute to issues and faulty results.


If an independent Apple authorized service provider is an option, (the computer may be too old

for Apple Store to restore it; they may be able to transfer the old Libraries from it to a new one)

the old and tired Mac may have some life left in it. Also, it may be the hard drive is too full of

user accumulated content and the Yosemite was unable to budge.


A slow internet connection may also have been a partial reason for problems, from trying to

upgrade from Snow Leopard 10.6.8 to Yosemite 10.10... Could be the computer didn't like it.


Without exact system specifications, and that means hardware build version + etc, it is hard to

say if the old Mac was ready or able to accept an upgrade. Some are happiest with 10.6.8.


A new hard disk drive, installed in the Mac, by use of Snow Leopard install DVD so it would be

formatted correctly and a new system installed properly, is one way to get the computer to run.

And the old hard disk drive could be put into an external drive housing, and attempt to transfer

or migrate any old account data, tried with Migration assistant; in the absence of time machine.


Then the old HDD would not be overwritten by a new OS X. It may have seen overwriting by

the Yosemite installer; or it may have failed if the hard drive was weak, prior to full installation.

A non-bootable drive may still be accessible by a healthy Mac. Also, a universal USB drive kit

could be used to attach a bare drive to a working computer to try & use a hard drive...

A 'univeral drive adapter' of some type may be located at a good computer shop, a better one

is this http://eshop.macsales.com/item/NewerTech/U3NVSPATA/ - newertech USB adapter.


Best of luck in this matter! 🙂

K,


To answer a question in your response - she did the original attempted download via the Apple store, and my first attempt to access her desktop and get past the Yosemite install screen was to insert a Snow Leopard install disc hoping, as you say, I could reinstall Snow Leopard with the option of retaining original work, but it had no effect, still the same Yosemite install screen - the install screen does not mention Yosemite, by the way, just says installing system X - but it has to be Yosemite as that is what she downloaded - another wee problem is how to get the Snow Leopard disc out of the machine - it doesn't eject when the machine is sut down and of course as I can't get the usual desktop screen with its icons I can't see the Snow Leopard disc icon.


Also because I can't access the original desktop I can't get at System Preferences to switch on File Sharing (which might be important) - From the Yosemite Installing screen the only items available on the Apple Menu at the top of the screen are limited to restart and shut down - thank God for the shut down option at least or the computer would remain on till it run out of battery


Best regards



Kincaid
