Mac pro video card not working

It has the upgraded Apple HD graphics card. I use all 4 SATA hard drive bays. My config is 1. SSD with OS 2. Trad HDD 3. Time Machine drive 4. Apparently that was a mistake, becasue now my Mac boot or even won't post video. It shuts itself off after trying to boot for about 10 seconds. I have tried:.

Lion USB. I have time machine backups, I just need it to start posting video again.

Everything on the boot and OS drives should be the same, if I can just get video to post, it should work again. Any ideas greatly appreicated!! I'd start with disconnecting all SATA drives, putting a new one in, and booting from hardware supported version of OS.

Rule out any hardware problems first. Will do, thanks. Also going to try putting the original graphics card back in if that doesn't help. Luckily I held onto it. Try an SMC reset. Otherwise I would run a disk check on the boot partition. You should be able to by booting into a bootable installer. Shut down the computer. Unplug the computer's power cord. Wait fifteen seconds. Attach the computer's power cord. Wait five seconds, then press the power button to turn on the computer. I can't wait 5 seconds, as the KB says to do.

I hear the Apple "chime" then the the Mac turns itself off after about 10 seconds. If I hold down the option key, the machine stays, but there is still no video. Man, I am super glad I kept the old graphics card! I'm reverting back to OS X Lion Going to check the Apple HD graphics card to see if it died after Lion is stable I'm sticking with Lion for the foreseeable future.

Although I'd much rather have a newer OS, Lion is the latest one supported and I've found machines are much happier when used as the manufacturer intended. With the SSD and other upgrades, there is little difference in performance with the Mac Pro, even the benchmarks prove that. You sir, have inspired me!! I'm loving the possibilities here. Should've done my homework more before I jumped in on Mtn Lion, but I'd read bad things about Mavericks. My graphics card ATI , 1 GB pales in comparison to yours edit: after re-reading your post I think they're about the same actually , but I've read it should be able to run Mavericks no problem.

Also, I'm curious if you've been able to get Messages working in Mavericks.

I never could login to iMessage, that's how I broke my Mtn Lion install. Just put in new cables and the monitors are one years old. Have 64 ram on the machine. Have the new Radeon RX a month ago. When powering down on the Mac it will give black and white checker board screen before it goes off. So is it the new video or is it in the machine itself?

Does less than one hour of operation count as new, for you? I have an unemployed RX; make me an offer, if you are US-based. Have you or anyone tested dual monitor configurations with either a GTX or in an older Mac Pro? That would be good info. Yes , I have a mac pro 3,1 upgraded to Mohave dosdude just like you.

I have a mac flashed GTX and I run dual monitors with no issues. My Mac Pro 5. It seems no Nvidia driver is available for Mojave, although I am told that one was submitted to Apple for approval soon after Mojave was released. Six months later, this approval is still on hold.

How to Verify Your Mac’s Hardware Is Working Properly

A big thumbs down to Apple for treating their customers with such utter contempt. It should not be possible to upgrade the operating system unless the hardware is compatible with the upgrade, and Apple needs to address this problem without delay. It would be helpful if update scanned your hardware for compatibility, but sadly. A sorry situation!

Nobody knows when the right driver will be released. Some cards have a driver built into the operating system by Apple, but these are usually of moderate performance. I would really like to return to High Sierra, but sadly my backup disk failed! Successful update from Late Mac Pro 4. Then installed the Sapphire Radeon Pulse RX with double mini 6 pin to 8 pin connector — not easy to find — and updated easily to Mojave. Original processor and 16 GB old Memory, no serious trouble so far.

So I need to know if it will works fine, and may not cause problem with the original power supply. I seen that the rx works fine with mac pro , and I think that there are no great difference in power comsuption between these two cards, please help me to make my choise. Not yet endorsed by Apple, as the current draw seems right on the watt limit. A bit tempted, but might wait to see how it goes.

The performance is better with older Snow Leopard on this system, so I installed Mojave on another partition. Thanks so much, I am going to understand what you are saying. I want to do this, but I am a bit paranoid. I am on I just want to make sure I know what I am doing! Thanks for the info. I would guess that it would run better that way.

This message was directed to Sobriquet Johnson. I personally would flash the motherboard firmware to that of the 5,1 model. The only hitch I have heard is that the Apple Store will still see your Mac as a 4,1 model and not let you download Mojave. If you know someone with a Mac that will download it, do so and make your USB installer stick.
