Mac Pro :: Won't Work With 24" ACD To 4870 / Can't Work With Adaptor
Mar 13, 2010
I just picked up a second 24" ACD with the mini display port. I already have one, so the mini display port on my 4870 is in use. So I think I need an adaptor to go from the MDP on the second display to the DVI on the 4870.
However, this adaptor has a male MDP and a female DVI. The ACD has a male MDP, so I think I need an adaptor which is a female MDP and a female DVI.
I find it a little strange that it is so difficult to put two identical monitors on the Mac Pro. I did search the forums, but kept getting hits for the above adaptor and I am not sure how it would work.

In the last 2 weeks before my MP shipped, I've asked 3 Apple Geniuses at Apple stores and Apple Tech support about running dual DVI 23" Cinema Displays with 4870's. They ALL said I would need a second card. When I attempted the install, there were only 2 power cord clips on the back face of the main board. Both being used by the onboard Radeon 4870. What to do next? Another call to Apple support offered me a nice Indian girl who I could not really understand. Finally, I called a local non-Apple shop that I frequent for hardware and service issues. The very nice service tech told me to take the 2nd card back, since that original 4870 will drive 2 monitors perfectly, in my case, with a simple Mini DisplayPort to DVI adaptor for the 2nd 23" display.
how would you install any 2nd graphics card, if a 4870 takes up both power clips?

Airport seems to have stopped working on my iBook G4 (it only detects networks intermittently). If I buy a USB WiFi adaptor, will the iBook still backup wirelessly to my Time Capsule and share (screen and file) with the other Mac in the house?

I have a 2009 - Mac Pro 8 Core with a 4870 Video Card. I know this card uses both the six pin power plugs. I want to add a ATi 2600 Xt card to be able to drive a third monitor and Wacom Cintiq tablet.
Will there be any problems doing this? Does the 2600 just plug into the PCI slot and fire right up? Do I have to adjust the card from 16 to 8?

I am looking at putting one of these cards in my first gen Mac Pro and was wondering if anyone has had any problems with compatibility issues etc.
I am looking at getting one from bruinmacs and was looking for feedback from others that may have bought one and whether there have been any problems.

I have bought a flashed 4870 for my 1st Gen Mac Pro and it works fine. But yesterday i wanted to plug a second 23" ACD in and woundered that its not working.
Can i flash my card with another ROM so that i can use two monitors? In a german forum there are some people who has the same card and for them it works with 2 monitors.

I have an issue with my 4870 (Mac edition) that has been occurring since day one (when I purchased it last month), but it's not something that happens every single time.
I've run into a problem that the 4870 has trouble recognizing one or both monitors plugged in. If I shut off power to my displayport-connected main monitor, it'll throw the menu bar, all the desktop items, and application windows onto the second monitor (DVI-connected). This also happens when I shut off the second monitor (desktop items and app windows get shuffled to the main monitor).
The other issue is that on startup, it may just be slow to recognize one of them, and the above screen-swapping issues happen anyway, followed seconds later by the screen once again being recognized.

I recently purchased a second 22" Dell 2209WA to go with my Mac Pro. They are both running from the ATI Radeon 4870 on my Mac Pro (2009 Quad) but the Expose performance seems to be really quite poor. Displaying all the windows is very juddery and not smooth at all. Is that what I should be expecting now? I wouldn't have on a �2000 Machine. Going into Spaces is fine, it's just Expose thats poor.

Apparently, Apple is seeding updated Graphics drivers .
Can any of our GPU gurus hazard a guess at whether these will benefit those of us with flashed cards, or will they more likely brick them, or do we just not know until we test them?
I don't want to get my hopes up for improvements that might never happen!

So I have an Early 2009 Octocore 2.93 and I have a flashed ATI Radeo HD 4870 video card that is supposed to work on a PC but its flashed so it works on a mac. I know its not officially supported but the issue im running into is that the operating system cannot recognize the full resolution the HP LP3065 30 inch display is capable of. The display can run up to 2560x1600 on any other system but not with my ten thousand dollar machine. The windows side can display at the full resolution but Snow Leopard can only run 1280x800 and it makes the OS look like a pile of dog **** on sunday.
Anyone else run into this issue?
Heres the link btw to where this guy shows how to flash the card.

I am looking to connect my macbook pro to an Acer G24 monitor, but am not sure what best way to do it.The resolution of the monitor is 1920x1200, and it is a 24" screen, with VGA, DVI, and HDMI ports.My macbook pro is the late 2011 entry model.
Will there be a difference in the quality of the picture on my external monitor, depending on whether I connect using a HDMI cable or a DVI cable? I will have to buy an adapter for each of these, to plug into the mini DVI port on my mac, will this alter the quality of the picture at all? If I were to buy an Apple Tv, would I be able to plug it straight into my monitor using a HDMI cable? If so, how would I manage the audio, as my monitor does not have speakers. Would using a thunderbolt cable (with HDMI adaptor) increase the quality of the picture of my monitor?

MacBook Pro (13-inch Late 2011), Mac OS X (10.7.4), Apple TV, Thunderbolt, Monitor

I have a 2008 black macbook with 10.7.2 installed (2.4 GHz Intel Core 2 Duo, 2 GB 667 MHz DDR2 SDRAM). When I press caps lock, no green light turns on and letters remain in non-capital form. Even when I hold Caps lock for a few seconds, nothing happens. If I physically connect an apple keyboard via usb to my computer, caps lock doesn't work.

I told myself not to do it. Don't update the Safari software to 4.0, you know how they always mess up these things. And yet, per accident I did. Of course Safari 4.0 doesn't work. Every time I open it, it shuts down. iChat also doesn't work anymore, and even the Dashboard shuts down every now and then. In addition, the computer feels incredibly slow. I can't download rapidshare links on iGetter anymore and everything just feels wrong. Countless threads have been opened on this matter with a variety of different problems for different people. Yet I have not read a proper solution. I have seen all kinds of technical solutions being offered but I'm not a computer wiz and I do not know the terms they use. I just want to go back to Safari 3.2 or at least the one before the 4.0 But I read that deleting Safari 4 and reinstalling 3.2 won't work because of a certain webkit that got installed with it, making it impossible to go back.

Since I just lost my hard drive on my iMac 24 Intel, I am using external hard drive to backup via Time Machine. My question is what procedures are needed when you disconnect ext. hard drive? Do you change Time Machine from ON to OFF?
I know that I have to eject the ext. hard drive using proper commands, but what happens whenever I reinstall the ext. hard drive? Does Time Machine start over from the beginning or just update for changes since my last backup via Time Machine?
When I go on trips, I store ext hard drive in a safe and this is why I am asking.

Why are Apple applications are so much larger than similar Microsoft applications. Some examples: Word -12.7 MB and Pages - 273.4 MB: Excel - 11.7 MB and Numbers - 138.6 MB. Both Word and Excel are sophisticated programs and I would have assumed they would be large, and that since Pages and Numbers are relatively new so they would be lean, but the opposite seems to be the case. They all work well except Numbers is slow. Is that a function of size? Is obesity epidemic in programming as well as programmers?

Just made an image slideshow in Final Cut.
Just a bunch of images and some audio.
When I export via File > Export > Quicktime Movie..., the cross dissolves between images disappear when I watch the movie in Quicktime.
When I export via File > Export > Using Quicktime Conversion... the color looks horrible in the Quicktime movie.

I'm on a IMac OS X (version 10.5.8) and I just noticed a bit of a change in the graphics while playing Heroes of Newerth. I left all the graphic stuff on medium quality, and I've noticed now that when it is on full screen the picture is sketchy. When I minimize the full screen (apple m) i realize its a lot smoother than it is in wide screen (no kidding huh?). Before I thought it was just due to me having the IMac wireless, but I've noticed it's been happening for a week already and I usually get better bandwidth when no one is home. So is this a graphics card issue or what and if so how would i deal with this?

Just had to replace the logic board on my PMG4 DP 1.25GHz machine. For the life of me, I can't remember the operating temperature before I swapped the board. Currently it's running at 130F - 140F. This seem about right for the other folks running these machines?

I just got my new Mac Pro and installed a second 8800GT which works perfectly fine, and also 8GB (2x4) of OWC RAM. When I boot the system it now says 8GB RAM instead of the 10GB I have installed (8GB from OWC and 2GB default Apple).
I have them installed as:
Riser 1:
2GB | 2GB | 2GB | 2GB
Riser 2:
empty | empty | 1GB | 1GB
The little book that came with the system said if I had 3 pairs to use slots 3&4 which is why I set it up that way. Are there any issues with doing this? Do I have the RAM in the right slots? How can I set this up to see the full 10GB?

I gave him my Mac Mini (it was one of the first ones out, several years ago), so we can communicate a little easier, and just because it's time he goes Mac! Anyway he gets home and tells me I forgot the vga to dvi adaptor. >.< I had forgotten its existence since I never used it... Is this: it? The code on the package is 603-0607. I googled that code, and did find something about DVI, but I figure it can't hurt to ask, before I go and mail a package all the way out there. Does that look like what came with the old minis?
