Since a couple of weeks I am facing weird crashes on my 8core Mac Pro (May 2007). They happen from time to time. Sometimes directly after starting up, sometimes there are no crashes for a couple of days.
I have a problem with my iMac 2 GHz Intel Core 2 Duo (2 GB 667 MHz DDR 2 SDRAM), running OSX 10.6.5. OSX crashes and freezes all the time. Nothing works anymore. Sometimes it just freezes, and I can only move my cursor, but nothing reacts anymore. Sometimes the screen blacks (or sometimes blanks) out or shows the weird moving colours as shown on the photo I just took below: After restart, it often happens again and again. Then the iMac is fine for a couple of days, before it freezes again. Can anyone diagnose the problem from the info above?

I shut it down using the shut off button and unplugging it from power for more than 5 munites.
I turned it back on, it does the usual startup chime and then gray screen. I have restarted twice from the shot off button and still getting the same result.

I see the numbers of everything from Core 2 Duo, to the slightly faster and cooler Core i3, to the supposedly faster core i5s and i7s. The benchmarks go up accordingly, but I found this does not always equate in a faster experience on most tasks.
Here's my experience so far on processor upgrade:
In one computer trade school re-certification class I am in, we are working with Windows Server 2003 on a Quad Xeon platform and it's incredibly slow.
But in a previous class we had the previous generation server edition on older Xeons, and while not fast, it was much better. On paper the newer multi-core Xeons should have made a difference, but could 2003 server software be that much more bloated than the previous Windows server edition that it would stall like that and make us wish we had the older setup?
I am going to try out the Adobe CS lab and put the new high end Dells to the test there and see if they work better than when we had an older CS version on older Xeon equipped Dells.
I don't know if this is something to do with Dell, or if Apple's increasing processor bumps/generations are going to similarly not make a difference in the speed things appear to go at, whether it's Adobe stuff, server stuff, or anything else that needs power.
I know somebody who plans on a Core 2 Duo, i5 or i7 MBP and I was wondering if the higher end processor is worth it in that case (iMovie being the main program of use).
I have a week 50, i7, 2TB Imac. It has a very distinct yellow "tinge", and the Bluetooth does not work properly. Every time I reboot or start, the "Bluetooth setup assistant" starts, which I have to force quit. The wireless keyboard and mouse work fine, but I can't add either of my two bluetooth headsets. They pair, but when I try to activate them, it goes to the bluetooth settings screen, where it says that bluetooth is "off", despite the on checkbox being checked and the keyboard and mouse working. I called support and they had me do a bunch of things, the last thing being reinstalling the OS. Didn't work. So now I need to call them back. I have two problems, the yellow screen and the Bluetooth. Should I ask for a replacement? I see that a lot of people have gotten a replacement just for the yellow screen problem. I have two faults.
View 2 Replies View RelatedThe first MacBook Pro I got had the screen off centre (it was left in the bezel - there was no black perimeter on the left but a big one on the right). I did notice it also had a reddish tint to it. That display was a 9CB7.
The replacement has the screen more centred, so happy with that. But there is a red tint to this one too on the top left.
The bottom right is fine, colours look great, but middle and top left there is a red tint. The Safari bar is very warm when I have it up the top left, but when I move to the bottom right, it is perfect grey.
Anyone else got the 9CB7 screen? Red tint to that?
I'm going to have to exchange it again.. and hope I don't end up with the 9CB7 or any other issues.
Just curious as to how much of an improvement in performance I would see upgrading my system as it states above, since my 2006 machine is 3 years old and getting close to the end of my apple care, figured I would trade it in and upgrade.

View 5 Replies View RelatedI have an opportunity to get a single 3.0 GHz quad core Clovertown.
Should I go for it? There's no advantage to having two cores in two sockets versus having four cores in one socket, right?
is it even possible to upgrade an old dual core powermac g5 to a quad core or even an 8 core.
I have a dual core one and i really need to upgrade to a quad or even 8 but it is so expensive to buy a whole brand new one and i was wondering if there was a way to just get a new processor and more ram or what not.

What you say guys?
I know the same article is on main page
So the older Mac Pro's from 2008 have 2 2.8ghz Quad Core Intel Xeon processors, without hyperthreading, for a total of 8 cores, and the top of the line iMac has a Quar Core i7 2,8ghz with hyperthreading for a total of 8 (virtual) cores.
With the ghz being the same but less "real" cores, but probably newer CPU architecture, which CPU will actually be faster?
There's a lot of people wondering if the 13" MBPs would have been a lot better with a Core i3 processor, but everything has been just hangups over perceived old vs. new technology, and really the only thing the Core i3 adds is Hyper-Threading, but it doesn't have Turbo Boost, which helps the Core i5/i7s tremendously. Let's compare using Geekbench since it is cross-platform and one of the few available sources of info...
Core 2 Duo P8600 2.4GHz (~3362)

vs.
Core i3 330m 2.13GHz (~3472)

Core 2 Duo P8800 2.66GHz (~3700)
[URL]
vs.
Core i3 350m 2.26GHz (~3680)

As you can see in both cases, the difference is pretty minimal indeed, and in single threaded applications, the C2D will easily outdo the Core i3 which lacks Turbo Boost and runs at lower clock rates.
And you get a 320M instead of Intel HD graphics with the new 13".
The Geekbench results from the old 15/17" to the new 15/17" are quite an order of magnitude better.
So unless people are expecting Core i5 processors in the 13", sticking to the C2D was actually a good decision, and given the differences between 2.4 and 2.53 isn't so large, one is far better buying the base 13" and then putting the money saved towards a good 7.2k HDD or SSD.
Note - I took averages of the 32-bit numbers and added them.
Note 2 - The C2D Pxxxx are 25W TDP processors, which are more efficient than the Core i3 which are 35W TDP processors. Less heat, better battery life from C2Ds.
I've been debating whether or not to upgrade my 3 year old 15" Macbook Pro that has a 2.2Ghz Core 2 Duo (Santa Rosa) to the new 13" 2.4Ghz Macbook Pro. FYI... My current system also has 4GB of RAM. Since both systems are Core 2 Duo, what kind of speed bump am I going to see? Would this be a substantial upgrade?

The ivy bridge processors are coming out soon (or may already be out). I have heard that macbook pro 13" models might be able to use the new processers due to their lower energy useage. I presume that I will be able to take my mac to an apple store and have it installed. Is this information true?

Just in case Apple surprise us with a Sandybridge Quad core, and even if they don't I was wondering the following.
1 ) During sustained use in 3D gaming does a Quadcore with lower clock speeds beat a dual core with higher clock speeds.
2) Can the quoted turbo speeds be achieved in sustained use (ie 3D gaming where maximal load can be applied for a couple of hours).

I know other threads exist, but they don't have responses specific to me so what's the harm in one more?
So, I am going to be selling my late 2008 15" MacBook Pro this week to get a new 27" iMac and I just need some legitimate advice from those "in the know" on processors.
I plan on having this iMac for about 3 years to do the following tasks:
1.) Record and edit HD cable (1080i) from an Elgato EyeTV HD - will include some encoding of 2+ hour sports game recordings
2.) Some light editing of 720p iPhone 4 clips in iMovie
3.) Surf the web, iTunes, iPhoto, Mail, and all the other standard stuff
Assuming budget is an issue, would you recommend me spending the extra money for a Quad Core i5 iMac or would I be ok based on the info above just going with the base Dual Core i3 model?
Like, will there be a considerable difference in the two machines (factoring in processor and graphics card) that will really be worth the extra $300 - $400 for 3 years of use?
I have been offered a 2008 3.2GHz 8 Core with 10GB RAM, ATI 4870, 320HD, no warranty/applecare left.
Or, I can buy a new 2009 2.93GHz 4 Core, 3GB RAM, 640HD, GT120
Both about the same price: $2850.00 USD
Which would you choose, and why?
I'm one of the many many people who are juggling mac pro options in my head.
is the 3.33GHz Westmere worth the extra 640? Probably not, but now much faster will be it? 20%....30%?
I think I'm set on either of these two options, mainly using FCP and photoshop and a bit of motion. maybe a bit of gaming
Also I can max out them four RAM slots and get a 5870 with the extra cash.
I've upgraded my iMac 4,1 to a core 2 duo processor in order to install Lion although I still get a message from App Store saying that Lion cant be installed on my computer - I have all the basic system requirments - RAM - free space - latest version of Snow Leopard and processor ...

My 2006(ish) Intel core 2duo 2.16 mhz 20" imac wont start up, it only stays at the loading screen, how can I fix this? I have tried:
• safe mode reboot
• restart using p, r , command and option (resetting the pram)
• restart using the original Mac OS 10.4 disc
• restart so I get the image of the HD but I can't click on it to continue and restart again! • single user mode (CMD+s keys at bootup, and then /sbin/fsck -fy)
It just doesn't do anything else than display the grey screen, the apple and the spinning wheel (sometime, I do get a scrolling bar also!). I managed to perform a hardware test from the Mac OS disc and there seems to be no hardware problem. Nothing works.It stays stuck on the grey screen, with the apple and the wheel turning endlessly.

When I boot up this ibook it works fine for a little while then it gets all wavy and crashes. Would this be the screen, board, or the connector? Everything looks solid.

View 1 Replies View RelatedEvery few weeks my iMac will suddenly freeze, the screen going black or white or pink etc. The only way I can get the computer back is to hold down the power button to force a shutdown. Then after a restart everything is OK for a few more weeks. Usually it occurs when I am on the internet. I click on something and suddenly the computer is frozen. I am on OS X 10.6.8 and usually use Safari. Ironically when I opened this forum 5 minutes ago there was a similar sounding problem at the top of the list!

When switching from the normal video window to full screen while watching a podcast in my iTunes library, the program immediately crashes. I've tried several different podcast, starting with the smaller video window, then trying to expand using the opposing diagonal arrows symbol in the bottom right corner. The result has been the same. As soon as I click on that the window screen goes black, and iTunes shuts down. I'm on a MacBook Pro 4,1 using OS 10.6.8 and iTunes 10.6 (40). Meanwhile, hope someone is working on the problem with the clickable scroll bars being inoperable.

I have faced some known symptoms of a problem for which I was not able to find any sound resolution. I have an account with which I am unable to login. When I enter login details for a session, the system immediately kicks me out showing a blue screen, logs out and goes back to the login window. An interesting observation during a sudden logout is that I spotted a vague image or window of an open application (probably Finder) at the background which is like 95% transparent in comparison to the Mac's desktop and therefore barely visible. The white-ish edges of that window is more distingushable though for a short duration.
I can ssh to this username and work remotely. But there is another username which has not been affected with this issue and works fine. The console logs show that loginwindow process is crashing everytime. Look at the output below. There have been notes with similar effects but with specific causes (e.g. MS Excel 2004 inc Rosetta, Blootooth peripherials, eBook Studio, Photoshop CS3 etc.) which might be related cases.

The first Core i7 and Core i5 benchmarks are available. Quite amazing to see how much faster the Core i7 is even compared to the Core i5. (via digg) I'll definitely go for the Core i7 now that I've seen these results.
