Hello:
I have an Mid 2009 Macbook Pro 15, which I cannot get updated to Mavericks.....
Here are the details:
- this computer had issues in the past with replacement HDs ( various WD Blue and Black models ). I had to downgrade EFI to 1.6 to make it work with WD 750GB Black.
- I have tried in the past OS X 10.8, it failed ( many beachballs afer installation ), so I went back to 10.7
- now I would like to sell the computer, with a clean Mavericks installation
- Mavericks install fails, the difference from the 10.8 installation is that the installation itself fails
- I have even tried an Toshiba 500GB HD from my 2011 Macbook, same failure
My guess is 10.8 and 10.9 do not play well with EFI 1.6. And I cannot go to EFI 1.7, unless I limit the SATA speed to 1.5 GBPS.
I am wondering:
- is there an HD or SSD, where the SATA negotiation can be forced to 1.5 GBPS ? Via jumper settings, or some engineering utility ?
- any other advise ?
Thanks, Paul.
