Hardware :: Downgrading/Switching From Penryn MBP To Penryn Black MacBook
Jul 14, 2008
I think I have to give a brief history of my Mac life first. I previously owned the last generation iBook, then a MacBook (entry-level) 3rd gen before I upgraded to Penryn MBP this April.
I bought the MBP because I fell in love with the keyboard when I got to try the display unit in one of the Apple resellers here (I am from Manila, btw) so I sold my MacBook then upgraded to the Penryn MBP (entrylevel - 2.4ghz, 15inch).

Wouldn't that have been more impressive than that razor blade thing they're calling the MacBook Air?

I originally purchased a SR MBP a couple weeks ago and come to find out, the LCD was bad and Apple declared it DOA. I went to the Apple store and swapped it out for a new 2.4GHz Penryn MBP. I am running Vista via bootcamp and am noticing a high pitched whine coming from the top left hand side of the keyboard, near the LCD. Puzzled as to the cause, I started playing with some controls to see if anything made a difference and noticed that when I dim the LCD to the min, it almost goes away. When I turn off the LCD it does in fact go away and when I increase it to maximum brightness it also vanishes. The noise seems to be the loudest when the LCD brightness is set in the middle. This problem only occurs in Vista, not OSX. I thoroughly toyed with the brightness in OSX and listed carefully, but like I said, not noise is present.
Should I be concerned and call Apple, or just ride it out? It does bother me a bit considering I use Vista for Office 2007 tasks. However, since the problem only occurs in Vista and not OSX, it this indicative of a software issue, or do you guys think it is hardware related? cmm26red

Anyone know if I can go to the AppleStore to fix this? I've had this Penryn since March. Also any idea how long?

I bought 160GB X25G2 only to realize (later) that my MBP17 SATA is indeed limited to 1.5Gb so it made me think - shouln'd I utilize this Intel in my i7 iMac and get some cheaper slower SSD for my MBP? If so which one?
Or is the read speed only half of benefits of SSD and the access time and write management being the other part? (I read about some issues with jmicron controllers etc.)

I take a T7200 board and put it in a penryn T8300 machine? I know little things like the battery connector and the inverter board connector change from removing so many of these boards, but I never kept good documentation of the connector types between the different boards.
I am totally fine with this not being the same specs as it was before, it will still be a nice machine, but I don't feel like spending $500 on a logic board for it.

I have a White MacBook (13-inch Early 2008 model A1181) Penryn 2.4Ghz. The current logic board in there is Apple part# 820-2279-A. Is a late 2007 Santa Rosa 2.2Ghz board (with the same part number 820-2279-A) a direct swap for the Penryn board?

How can I tell what my MBP is? 2007 2.4 model.
Am I right in thinking Penryn is a newer better motherboard?

so I'm thinking of upgrading to 4GB RAM for my Penryn MBP....and I'm wondering if i can swap my current two 1GB sticks in a 1.25GHz Powerbook G4 that my friend has? I double-checked and found out that the Powerbook G4 could take in 2GB of RAM max.

I've just bought a 500GB Western digital scorpio blue HD. I'm going to put it in my mac mini which I don't have yet. I have a macbook at the moment, so want to format the new drive so it's ready to put straight in the mini and use
Is it OK if i put the 500GB HD in the macbook, then boot it from disc and install leopard onto it that way? Or do i need to format the disc in some way before I install leopard?

I just got a new MBP i7, and whenever the graphics switch from the Nvidia 330m chip to the Intel chip, the screen "flickers" black for a short moment before reappearing. Can anyone with a new MBP comment on this behavior? It doesn't happen on the switch from Intel->Nvidia, just the other way around.

I have had my iMac for about 4 months, i have been using it as my main desktop since. I have noticed black smudges, kinda like finger prints on the screen that would not go away after cleaning it with a damp cloth. I removed the glass panel and cleaned inside the glass and the problem still remained.
This is not the main issue, i can live it with. I have two iMacs with the same specs, one is in my main home office that i used most of the time while the other is my home that i use not that much. The smudges does annoy me when i watch movies a little bit but its not enough to get me to replace my mac. I was thinking since i used my office iMac more is it possible to switch the hard drives on them so that i get all the info from my office iMac onto my home iMac without complications?
Since i dont use the home iMac as much as the office one i can tolerate a few black smudges more and i would have an iMac in the office that looked new.If i switch the hard drives will it be as if i switch macs and if anyones knows how to fix the black smudges it would be a great help.

I have been having strange issues with my 2.13GHZ SSD Air hanging on boot disk errors and a complete restore didnt help much. Also the fans would run when doing next to nothing and the air was cool to the touch. I cant really think of anything else to try so im going to try to have it replaced with a refurb rev B. Is there any internal differences between the two besides speed etc?

Upgraded to the lastest OS in December and its utterly killed my 1st gen MBA - within 15-20 minutes of watching video its operating at 100 degrees and thermally cuts out. Genius bar has replaced the thermal module and then advised me to go back to a previous OS as they reckon the machine simply can't handle the OS. I'm pretty sure it had Leopard on when I bought it, and I soon after upgraded to Snow Leopard. Can I get hold of installation disks anywhere? I've probably got the originals somewhere, but as half my stuff is in storage, not sure where. Â
Other thing is how do I physically do this? Whilst I've got an external disk to backup to as I don't have the airport extreme I used to have it connected through with me, time machine isn't recognising it as the back up. Presumably if I do back up I won't then be able to restore files anyway to an older OS?Â
My superdrive isn't with me either, so can I load the files from the disk to a USB stick and boot/install from there? I'm going to manually back up and will lose a load of software, but frankly the machine is useless now anyway so I've got to try something. No idea what it will do to my iphones and ipad apps, but again, I'm pretty well stuffed for a laptop as is..Â

I upgraded my 13" unibody MacBook to Snow Leopard today and immediately began experiencing the same wireless connection problems that everyone has been having (sure wish I'd Googled "wireless network problems snow leopard" before installing... but the reviews were so glowing...) I would like to downgrade to Leopard but am afraid I will lose my files as I did not clone my HD before upgrading. I have Time Machine set to backup my files whenever my external HD is connected, so I connected my HD and did a Time Machine backup before installing SL. I did not clone my HD, which I am now regretting, but I thought that Time Machine backups were safe enough. I have the Leopard disks that came with my MacBook.
What I need to know is how I can reinstall Leopard and then restore my files as they were from the Time Machine backup I made before installing SL. As I have never tried to downgrade before I am worried and am hoping for step-by-step instructions for how I would do this. I am reading that I would need to do a clean install that would erase my hard drive but am not certain that I would then be able to restore my files using the Time Machine backup I made right before installing SL. The situation is complicated by the fact that I already tried to restore from the Time Machine backup I made before I installed SL, naively thinking that this would fix everything, but of course it only restated my files as they were before the SL install without changing the system back to Leopard.
(1) Reinstall Leopard using original disks (assuming it would have to be a clean install, as in erase hard drive and install system, but if not, all the better).
(2) Hook up the external HD and then ask Time Machine to "restore" the image of my MacBook's HD from the backup made immediately before installing SL.
I would like to have my wireless back.

I just got the new upgrade and it's caused a definite problem for me.
I use some audio connection software and while it will transfer from the mac to the external disk (an IDE drive in a proprietary format), it won't do the reverse. I believe this was an issue even with 10.5.3.
How can I go back to 10.5.2 when everything was rosy? Can I just download the 10.5.2 updater off the Appe, site and run that? Or do I basically need to back up my machine and reinstall my whole system over again?

Is it possible to delete the whole software system from my iMac (version 10.7.3, Lion), and put on everything from my MacBook (version 10.6, including all applications, like the older iTunes version etc.) on it? Not so that I'd see my MacBook on my big screen, but so that the iMac would independently run with 10.6 instead of Lion? The iMac is new and came with Lion.Nothing I work with/on on an every day basis works with Lion and I'm ready to throw the iMac out the window. Everything's fine under 10.6. I just wanted a bigger screen and more space.
I'm sure there are other threads about this when you know where to look, but I don't. I'm not very knowledgeable with computers, but I start to understand that I'm not the only one having a set of problems with Lion.

Basically I installed Snow Leopard but am not happy with it, buggy etc. I want to downgrade to regular Leopard. Is there any way I can do a Time Machine backup now just to save my "user files" and not my system files. Basically I would like to do a system restore but take my current state of user files in Snow Leopard. Is this possible?

After I bought and installed Snow Leopard, I realized some of the most important apps that I use do not work under the new OS and I've been waiting for weeks (months maybe) for some update from the developers but seeing as they are more likely to wait, I've decided to downgrade back to Leopard again, the thing is that I'm on a VERY tight schedule these weeks, I have a lot of deadlines to meet and I don't want to install the apps that do work on Snow Leopard back again in Leopard. I don't have a Time Machine backup from back when I was on Leopard, and I haven't even made one of SL either, just an external HHD with my data (but no apps).
I've read online that people are having a hard time downgrading because there are a lot of errors in Time Machine and Migration Assistant, the most common one I've read about is that the Migration Assistant does not allow you to migrate from a newer OS to an old one. Since the most important thing I wanna migrate are the applications I've already installed in SL, this would be counterproductive.

I have a new 27" 2.66Ghz Quad Core iMac which has got 10.6 installed. Does anyone know if I can go back and install 10.5?
Reason being, we run a content management system using quark 7.5 and are unable to upgrade to v8. There are operating issues running quark 7.5 on 10.6 and if I can go back to 10.5 that would solve everything.

I have recently downgraded my OSX from 10.9 to 10.8.5. I downloaded Mountain Lion on another computer running 10.9, and I partitioned a hard drive to boot the software. I was able to run 10.8.5 fine, but finder never opens. When I click on finder, open trash, or open a folder on the desktop, finder becomes the current application, but nothing else happens.Â
I am running an early 2009 iMac with a 20 inch display.Processor: 2.66 GHz Intel Core 2 DueMemory: 8 GB 1067 MHz DDR3 (originally 2 GB)Â What works:I can spotlight search any file or applicationI can open any file on my desktop and any application on my dockI can view files in file browsers (such as selecting an image to upload)Â What doesn't work:I can't open finder, trash, or any folders on the desktop.
Preview crashes when I try to open a file.Menu bar items in the dock display differently (see picture)  What I've tried:Creating a new account (still the same)Setting finder to assign to different desktops (doesn't change anything)Hiding and showing finder (no change)Repairing disk permissions in disk utility (nothing)Relaunching finder (nothing)executing killall dock; killall finder in terminal (nothing)booting the mac in safe mode (still doesn't work)deleting finder settings via terminal (no change) Also, when I booted up the mac, it said that the boot-up failed. However, it opened up 10.8.5. Other notes:All administrator accounts were changed to standard accounts.When I create a new desktop, it is labeled as DesktopNum.

I've been having a few problems with my MacBook Pro ever since I upgraded to Snow Leopard, and some of these problems haven't been remedied even after several reinstalls. The main thing that's bothering me is my screen has started to flicker slightly (most noticable when a page has a white background), and it occurs on any brightness. It used to do this in Leopard as well, but not to this extent - it only ever did it if I was running on battery power and if the brightness was turned down quite low. Under Snow Leopard it's doing it under all brightness levels and regardless of if it's charging or on battery. It doesn't happen at all in my Boot Camp partition, so although it could just be a hardware thing that happened to start around the time Snow Leopard installed, I'd like to reinstall Leopard and see if it helps at all.
However, my question is - I have a Time Machine backup from Snow Leopard, would I be able to use this at all after I reinstall Leopard? Even if it's just to get my documents and apps back?

OS X 10.7 is clearly the most advanced operating system ever (until the next one) but I'm not digging it at all. I wanna go back to 10.6. I still have my 10.6 disk. Upgraded from 10.6 to 10.7., and am now on 10.7.3. Tried running the 10.6 install disk at boot-up and the 10.6 install was all going fine but then nearly at the end Installer said "Installation Failed. Some support files couldn't be found."
