I'm trying to set up a MacBook 4,1 as a replacement for a dead MacBook 7,1:
originally trying to take the internal drive from the dead laptop and move it
directly into the replacement.
However, installing a new version of MacOS on the drive ran into the sand, so
I took Sam's advice, and bought a new drive; installed Snow Leopard from a
DVD, migrating user accounts etc from the old drive - all worked fine. I ran
System update twice until it said everything was updated that could be. Now it
was on 10.6.8, and had all the data from dead laptop, happy as could be.
Then I attempted to update from Snow Leopard (10.6) to Lion (10.7). I logged
into the App Store on the machine - I've bought 10.7 before so it offers it
for download again. When I run the "Install Mac OS X Lion" app it runs, says
it is complete, restarts the machine... and then shows the 'no entry' sign and
shuts down. Now the machine is unbootable.
I can boot off the Snow Leopard DVD and repair the install, it's back to 10.6.
Run the "Install Mac OS X Lion" app again, same issue.
So I have three drives
drive A, 160GB, has 10.7.5, was original internal drive
drive B, 250GB, no longer has working System, came from dead laptop
drive C, 320GB, has 10.6.8, currently internal drive
I can still boot the machine from drive A, mounted externally. (Just for fun,
I tried booting from drive A, then running "Install Mac OS X Lion" and
directing it at drive C again... same result, it doesn't report any issues,
says it has successfully completed the installation, but the machine won't boot.)
Everything suggests this should be possible, but in practise it just doesn't
work. Is there something else I should try? Or am I just doomed to either
stick at 10.6, or get a newer old laptop?
TIA,
Ben
