MacBook Pro Memory Question

[KenJulio]

In regards to the 8gb, it is doable on the new unibody MBP, not the pre unibodies.

waters, which kexts did you have to swap out to run SL in 64 bit? I know my MBP is 64 bit EFI, so it should fire up fine, but the ol' 6+4 key boot isn't getting me into 64 bit mode.

Here's where I started: netkas.org Unlocking 64-bit efi Macbooks for 64-bit kernel.

I had posted this in another thread, but that one's a bit messy, so here's the synopsis:

1 - replace the boot.efi file and bless it (see post #35 in that thread)
2 - replace the WiFi driver using IO80211Family.kext (see post #66)
3 - edit /Library/Preferences/SystemConfiguration/com.apple.Boot.plist add arch=x86_64 (see post #22)

Reboot once, perhaps twice. I only needed one reboot.

Here's what the current system profiler says:

Awesome, much appreciated! I'll give it a whirl when I get back home tonight!

Thanks again! Just a mere couple minutes of work and I'm rockin and rollin.

You're welcome Brian. The real thanks go to the bleeding edge folks who figured it out in the first place. I'm just a Google head that can find them...

LOL! When is that not the case?! I did buy two laptops from them this Christmas for my daughters but they were just, what I consider, "toys" as they were only $450 each. Not bad, spec wise, but "cheap".

Memory (RAM) is definitely one of those things that makes or breaks a computer. Good RAM is always something not to skimp on... as you're seeing right now. Stay away from FRY'S for RAM as well.

What A Difference! No, Really, WHAT A DIFFERENCE!



I guess now I will dive into the Snow Leopard upgrade...

[srwatters]

Once you do that, then follow the instructions I posted above in #18 to get full 64 bit kernel goodness

I was reading up on it last night, and downloaded the little file in anticipation.

alright... everything so far has gone without a hitch... I got the proper memory from memorytogo.com this morning (that was quick!). I installed Snow Leopard, just did the upgrade process, and it was painless. All of my programs still work, just FASTER than before. Now I am trying the 64bit thing and while in terminal I get this, any ideas?

[srwatters]

Don't use the nvram program. Just edit the file I referenced to add the arch=x86_64 parameter. I used emacs as an editor, but if you know vi, you can use that too. The file must remain a plain text file though so you can't use textedit.

[dixonduke]

Alright... Thanks. I was just following post #35 too literally I guess. I really appreciate you sharing your experiences / advice.

The PLACE for MAC ram is OWC. You should be able to go to 6gig.

And they will give you credit for your old memory.
