Santa Rosa

I actually have two quick questions -
I just read something about Santa Rosa Macbook Pros, what exactly is it? And how do I know if mine is one of them. I purchased mine in September of 2007.
Second question is whats te max amount of RAM i can upgrade to? 2gb right?
Thanks

MacBook Pros that contain Intel's "Santa Rosa" chipset.
Which for the pedantic among us is actually none of them, as MBPs only contain 2 of the 3 chips that make up Intel's "Santa Rosa platform" IIRC

  • Design Limitation On ALL Santa Rosa MacBook Pros, 2.2 and 2.4 GHz

    While searching the Internet for answers to my new $2500.00 MBP headphone (output jack) has audible hissing sounds I found several posts on Macrumors.com and macintouch.com to explain the design Limitation/Problem. To summarize:
    The Problem
    The issue has three components, as described in this MacinTouch Report:
    - A low hiss that is constant whenever the audio circuitry is on
    - Static that occurs whenever anything is playing... even something quiet.
    - A series of high-pitched noises that occur somewhat randomly. The best comparison I've seen is that it's like listening to those hearing tests where you raise your hand when you hear a tone.
    The problem only occurs with low-impedance headphones (more on this below).
    Some Facts
    - The problem occurs on ALL Santa Rosa MacBook Pros, 2.2 and 2.4 GHz. It is a design flaw on Apple's part, and returning your machine for a new one will not help. There are plenty of people who say they can't hear the noise, but those people either have high-impedance headphones or speakers, or just don't have very good hearing.
    - Only Santa Rosa MacBook Pros seem to be affected by this particular static problem. I've seen some reports of other machines having audio issues, but they are always different.
    - The 'Audio Update 2007-001' that Apple released about two weeks ago doesn't fix it. It does fix a popping problem on all Intel Macs (including the SR MBPs), so it's worth installing, but that is a different problem than this one.
    - It does seem to be an Apple-specific problem; I've been unable to find any other reports of non-Apple Santa Rosa notebooks having the same problem.
    Just wondering if anyone else has had this issue with their new MBP?
    Thanks,
    B

    I experience the issue as well both in OS X and when I'm in Windows Vista.
    Whenever a program uses audio, there is an annoying high-pitched hissing noise from the built-in speakers.
    Of course the severity of the problem depends on the individual hearing ability, but everyone I have asked, have been able to hear the noise.
    Apple is known to be the first choice of audio professionals; however this problem is below that standard.

  • Fn + delete, other shortcuts not working with new Santa Rosa Macbooks?

    I recently received a brand new Macbook (Santa Rosa platform) as a replacement for my defunct old Macbook (which was the previous generation). I've noticed in bootcamp, Fn+Delete no longer serves as a shortcut for the Del key in windows. Nor does Fn+Up or Fn+Down serve as PgUp, PgDn respectively. Is this intentional, or something that I can get a fix for?

    I don't know if my solution will help everyone else, but I am using BootCamp 1.4b and recently reformatted my Windows drive. I had the Mac drivers for this backed up on my Windows PC and I used my PC to burn them to disk. After troubleshooting the problem described above for many hours (or at least one with the same symptoms), I found that the keyboard driver on my cd was corrupt (stupid CD-RWs never work right.) Since I had my ethernet up and running at that point, I was able to use the Windows on my Mac to pull the drivers off my network share and then I deleted the Human Interface Devices as described above and then reran the Mac driver setup program. After I restarted, everything worked fine.
    WARNING: Make sure you can do everything you need to do using only the mouse since the keyboard will not function at all after deleting the devices.

  • MBP Santa Rosa Airport Issues w/ Leopard

    Hi everyone,
    I've noticed a few "quirks" since upgrading to Leopard. Whenever my Macbook Pro (Santa Rosa, 2.4 GHz, 17", 4GB RAM) is searching for a wireless network to join, the system becomes completely unresponsive. The mouse pointer stutters and jumps around the screen and it's impossible to precisely control its movement. When I can finally manage to click on the Airport icon in the menu bar and select the appropriate network to join, the problems stop as soon as a connection to a wireless network is established. It only happens when the system is searching for a Network. I should mention that it does this when I am at work (where I connect via 802.1x and TTLS) and at home (where I connect via an Airport Express Router).
    Also, my computer no longer automatically connects to my work network (it does at home, though) after a restart or waking from sleep). I have my MBP set to prompt me for a password when it wakes from sleep, but it's near next to impossible to enter in the password because the system hangs so badly as it tries to establish a network connection. Of course, it doesn't connect unless I manage to click the Airport icon and specify the network I wish to join. Anyone have any thoughts on this?
    All of this is a little frustrating since the latest updates to Airport in Tiger fixed all of the connection issues I had had previously with my MBP. When I first bought the machine I had many issues with network connections (as did many thousands of others who bought this model). I was wondering if other MBP Santa Rosa owners have observed similar behavior since upgrading to Leopard, and if so, does anyone have any suggestions as to how to fix this issue?
    I should also mention that my Mac Mini C2D 1.83GHz (latest model) has no such issues so I think this is something that is still linked to this particular model of MBP.
    Many thanks!

    I am moving this over here, from the boot camp section. Hopefully this is more the location that this needs to be in. Well, my problem is not as extreme as some, but still an annoyance. I installed Leopard the first day, and immediately had HUGE airport issues. The computer would lose my hub. I run an Airport Extreme with an Express as a WDS. The computer would see the express, but lose the extreme completely. So no internet. If I messed with it long enough, I could get the computer to recognize the extreme, but as soon as the computer went to sleep, it would lose it again. I installed the keychain update, and the situation didn't get much better. Most of the time I get the "You are not connected to the Internet" error in Safari, and when I run network diagnostics the computer "finds" the internet again, and I get a "Network configuration change detected" message and all my lights go green.
    After I installed the Keychain update, I repaired disk permissions. Any ideas?

  • Leopard forgets color profiles when waking from sleep on MBP Santa Rosa

    I have a 15" MBP Santa Rosa with a 22" Samsung external monitor. I performed a clean (erase and) install on my machine. Upon waking from sleep, the computer seems to have forgotten the color profiles loaded for the displays. To correct this, I open system preferences and then the display option. As soon as the display options are shown on the window, my MBP loads the correct profile. This has happened for both displays, though far more frequently on the external display. The profile for my Samsung was created using color calibration hardware/software but the MBP display is running the stock profile from Leopard.
    Any thoughts? Has anyone else experienced this?

    same issue here. also had it in tiger, but much more frequently in leopard. seems to be whenever my display wakes from sleep.
    MBP 2.4 GHz SR purchased 6/07. also driving samsung 245bw external display (which has never been affected, unless perhaps my calibrated and default profiles aren't different enough for me to notice--the difference is severe on my built-in display).

  • Santa Rosa MBP - DVI to VGA Projector problems

    When hooking up a Sharp PG M20X using a [DVI toVGA cable] and a [VGA to DVI adaptor] the MBP sees the projector, but the projector cannot see the computer.
    This is a problem because, I may find myself in situations where this is the only configuration for hooking my MBP up to a projector.
    Note:
    1. A G4 Powerbook works fine with this configuration.
    2. The MacBook Pro drives the Sharp PG M20X projector DVI to DVI - without problems
    3. The MacBook Pro drives a DVI to VGA CRT monitor - using a [VGA to DVI adaptor] - without problems.
    Is there a solution?
    Thanks
    I have a 2.4 GHz Santa Rosa C2D MacBook Pro   Mac OS X (10.4.10)   Sharp PG M20X Projector (DVI-input)

    I think I solved this problem.
    It was in issue for me. My second monitor would only display the Windows XP screen when it was loading, then it would black out. I couldn't even move my mouse arrow to the other side. Then I fixed it, here's how (running Windows XP SP3):
    1. Start > Control Panel > Appearance and Themes
    2. Display
    3. Go to tab "settings"
    4. Double click the blue image with the "2" inside it. This is the second monitor, adjacent to your first, or primary, monitor. The blue box may be a desaturated, greyish blue, meaning that the monitor is disabled. Click it and it a box will pop up asking if you want to enable the monitor. Click OK, and then like magic, your monitor is resurected in it's Windows Glory! From there, adjust the resolution, and it should work perfectly.
    This isn't a Boot Camp compatability issue, it's just a problem with the lack of familiarity that users of OS X have with using XP.
    Have a nice day!

  • I have to input a password in order to log in each time I turn on my Macbook Pro Santa Rosa under Mountain Lion. Now my built-in keyboard suddenly doesn't respons at all. And the bluetooth function seems to activate automatically even though I turn it off

    I have to input a password to log in to my Macbook Pro Santa Rosa under Mountain Lion. Now suddenly the built-in keyboard doesn't work at all so I cannot use my computer. I also notice that the bluetooth function is activated automatically even though I turn it off. It looks for an external keyboard. Please help me out. Many thanks!

    I have the exact same problem trying to use the Remote app on both my iPhone 3gs and iPad 2 with either my Mac or ATV2.  My Remote app used to work on my phone - I can't recall if I ever actually used it with my iPad, but when I tried today, I got all the same results as you did (on both iPad, and then iPhone).  I  was using my ATV2 to play music from iTunes on my Mac and wanted to use the Remote app, but it would not connect to either device no matter what I did. 

  • Everyone with a santa rosa macbook pro..

    did the wireless fix sort the issues out!? i really need to no. without the wireless working on my macbook pro when i get it in a week..itl be useless!
    everyone whats going on???

    MBP Santa Rosa 17", now four days old, officially. Forgot completely about all the wireless/networking problems cited here, and, therefore, just joined my household network (LinkSys) Wednesday afternoon without thinking.
    Everything went perfectly.
    Took said MBP to another location this weekend (wi-fi'd marina), again forgetting about the potential problem joining that setup . . . but no difficulty again.
    Hope I'm not the exception. LOVE THE NEW MACHINE thus far: no display problems, no wi-fi problems, no kernal crashes, no nothing. Fingers crossed and smile on mouth!

  • Does Santa Rosa MB Pro support portrait mode on an External?

    A MacInTouch post says no.
    I'm now using a 17 in. G4 with an NEC 1980SX external that rotates.
    The display settings in my Tiger System Preferences allow me to rotate the display 90 degrees which makes working on 11x17 documents much easier.
    I want the new 17 in MacBook pro but no support for portrait mode is a bummer.

    For clarity on the external portrait display issue:

    Yeah, I have clarity...that's my post.
    I now need someone to prove it by actually trying it because I also need portrait support.

    I had been speaking with a Lenovo tech support agent earlier today, who had advised, "a Santa Rosa platform cannot run Vista 64-bit".
    I know. It did not make sense to me either. I guess the Lenovo agent was a newbie.
    I appreciate the clarification!

  • Macbook Santa Rosa Keyboard Swap

    Hello i have on of the first macbooks that was put out a couple of years ago and i was wondering if i were to switch the keyboard for the new santa rosa would the keys be the same as my old keyboard meaning would i still have to press F5 in order to turn up the volume even though the button is now on F12?

    I don't believe it will work. The keyboards have different part numbers.

  • Leopard on Santa Rosa's - Any problems?

    I am getting ready to head down to pick up a copy of Leopard. I was wondering if anyone has installed Leopard on the Santa Rosa chipset MBP models? If so, what was your experience?

    Wouldn't dream of declaring an OS defect free - Who'd take my word for it?
    But as of today Santa Rosa Macs in Apple Stores will be running Leopard and when I ran it on my machine it was fine so my point was that I'd expect it to be fine - that is take a Santa Rosa machine and add a fresh copy of Leopard and perhaps iLife.
    Michael pointed out a couple of glitches and obviously for any third party software, it depends on the software.
    As for the Airport drivers - they've been fine on our Santa Rosa machine - so I can't even say that's a defect I've come across.

  • Santa Rosa MBP Application Crashes with EXC_BAD_ACCESS (0x0001)

    I am having Application crashing problems with my brand new Santa Rosa MBP that arrived today. This machine is a 2.4 GHz 17" MBP with Hi-Res Glossy display and it came with 2 GB of RAM. I upgraded it to 4 GB but this problem occurs with the original chips or the new 2 x 2 GB chips.
    So far the applications that crash are Pages, Keynote, Aperture, Parallels Desktop, and iWeb. Other things I have tried are all right for now. Excerpts from the CrashReporter log of Aperture are below. All applications are crashing with an identical EXCBADACCESS (0x0001) and KERNPROTECTIONFAILURE (0x0002) at ... (this number differs for individual applications). Any ideas?

  • Xcode3 Completely Freezes Leopard 10.5.3 on Santa Rosa MacBook Pro

    Hi
    I am recently workin on a software project on Xcode3 (with all the latest Updates)
    with great disappointments i found out that very often (not every day or every time i use it) while in the process of editing source files the leopard user interface completely freezes (something like a kernel panic happens) and the only thing i can do is to force a shutdown.
    it happened to me at least 10 times (sometimes more than one time a-day). i have had user interface freezes before while using other applications but that i'm not having them anymore, the problem clearly re emerged by using xcode (which i never used before)
    i suspect it has to do with bugs in the graphics drivers for the GeForce 8600M GT graphics chip that is used by my Core 2 Duo Santa Rosa Macbook Pro (2.2 Ghz) and that Mac Os 10.5.3 Still has not fixed
    Anyone has the same problem? or any idea?
    Thanks

  • Santa Rosa MBP, Kernel Panics fixed by 10.4.10 Update v1.1

    A friend of mine who has the new 2.4GHz MBP just ran the 10.4.10 v1.1, and he no longer has KPs. Has anyone else tried this with their SR MBPs?
    I just got my 7th machine last night. I noticed that Apple has made the AC adapter smaller (similar to PB's). Who knows, maybe they changed something from the first release? Anyways, I tested it on battery, and within about 15 min, a KP while surfing the net! I will give the v1.1 a try when I get home tonight. will report back.
    SR MBP owners, pls let me know if there's any fix out there that I am not be aware of. Thank you!

    I run mine on battery all the time. Out on the deck, airports, hotspots, office buildings, hotels. Never had an issue with KP's.
    I purchased mine through PowerMax on a trade-in deal for my old Core Duo model. They are located in Oregon I believe.
    Something very wrong with being on 7. This is my 3rd one and only because I voluntarily keep upgrading them. Had a 15" Core Duo traded up for a 17" Core Duo and now a 17" Santa Rosa. Never had a single problem with any of them.
    Apple certainly isn't problem free, the same as any other manufacturer isn't.
    But honestly..if your on #7 I would have to start thinking that the problem is something other than the MBP. Some software...configuration...combination of hardware....something. I mean you would pretty much have to be the worlds unluckiest person I would think to have 7 bad ones.
    Honestly, I really do mean no offense, but you might want to start looking at other factors. Are you using 3rd party RAM in it? Have you tried other routers? Or just one you have at home? What security protocols are you using? What software have you loaded from the default configuration.
    I guess anything is possible, but statistically it would seem improbable that 7 of them could be suffering from the same problem.

Maybe you are looking for
