I just installed a ASUS radeon RX 560 installed in my MP5,1. I get no video, but 10.13.6 recognises the card in PCI devices when GT 120 is installed as well. My screen also registers a connected device when HDMI or DVI is connected, but no signal. Initially I thought it needed external power but...

Hello, I have a MacPro 4,1 dual cpu that I inherited. When I initially got it there was no power, so I replaced the PSU. It boots up now, the HDD Spins, and so does the fan on the NVIDIA GeForce GT 120. But I don't get any video out. I think the HDD was wiped as well. I will post more...

Hi I'm using a 1,1 Mac Pro on El Capitan. I have a GTX750 alongside the original 7300GT installed with the latest driver for this version. However, when I boot the system, there's no image. I have to reboot the Mac a few times, then it starts to work. Can you please help me? Thanks in advance

I have a Mac Pro 1,1 that I am attempting to upgrade for the purposes of updating it to El Capitan. I hadn't used the computer in a year or two, and there was not an HDD installed in the system. (I pulled drive from it a while back for another project) When I stopped using it a few years ago...

Hi, I recently got a B&W tower PowerMac G3 (don't know exactly which model) without DVD reader and HDD. I powered it and saw a grey screen with a folder and a question mark followed by the finder logo. Probably couldn't find OS X (duh). At least it booted. I powered it off, got a OS X Tiger...

A Short Introduction Hi MacRumors, you guys are my last hope. I come to you from the official Apple forums (Apple Communities), where a lot of people on iOS 10 on the 6, 6 Plus, 6s and 6s Plus, and the iPhone 7 are experiencing headphone audio loss, or just random bouts of complete audio loss...

Hi, All. I ordered a Macintosh SE from eBay the other day in working condition. As I'm sure you've all experienced before, USPS really doesn't care about your packages, so when I saw the USPS guy throw it off the truck I had a feeling it wasn't going to work... and I was right. When I connect...
