2006/2007 Mac Pro (1,1/2,1) and OS X El Capitan

[Krech44]

Hey Krech - I'm sending mine back. I've gotten it to output video putting it in alternate slots, but it's literally cutting the performance in half to run it with only 8 lanes. So strange that it's recognized and functional in the other slots and not the main. All I can guess is it's a power/PCI 1.0 issue...

Let's stay in touch and help each other out if we find another card of a solution. I'm crawling every forum and poking anyone I can...

Cheers

EDIT:
Is your GT610 the 1GB variety? I just searched Amazon and found this variation
for $50?!?
Is that too good to be true? It does say PCI 2.0... but if it works for $50, I'll jump on it.
I play games on PSX...

Yes the gt610 is the 1gb variety I bought it on Amazon a few years back and it works very well, for some sort of benchmark it runs minecraft around 70fps with the built in OSX driver

After talking to a few people just about ANY 600 series nvidia card will work I would go for a gt640 if you can

HAL - PLEASE don't make blanket statements like "any Geforce will work". There are hundreds of variations of cards with the "GeForce" moniker and I absolutely guarantee that your statement is far from accurate and likely to frustrate and waste someone's time. In my case, I've spent three super frustrating days on this and other forums because I have not been able to get my EVGA GeForce GTX 750 Ti SC to work at all in my MacPro 1,1.

I bought it from Amazon 3 days ago bc it has great specs for <$150 and I read here and in multiple other places that Yosemite and El Capitan support any nVidia card OOB.

This is the exact card on Amazon.

Not only does it not work OOB, it doesn't work with the latest web drivers in Yosemite or El Capitan. I've tried literally everything. No go.

I can't speak for sure about other variants of the GTX 750. Several people report it works for them but it gets very hard to be sure that someone is talking about a completely stock MacPro 1,1 or a hackintosh or something in-between.

I do absolutely guarantee that the card linked above will not work in a stock MacPro 1,1. I'll *speculate* that none of the "maxwell" generation will work because the PCI in the cMP is 1.0. Just my theory and I'd be happy to be corrected and educated by someone who is more knowledgeable than I. (MacVidCards?)

People are coming here looking for answers. I understand and appreciate that you're trying to help, but unless you have a MacPro 1,1 and you've tested every single GeForce card and they all work, don't say they do. Please and thank you, sir.

EDIT: I'm not trying to offend HAL or anyone else. I'm just sayin'. I read a similar blanket statement three days ago and pulled the trigger on the linked card. It's going back and I'm *still* not sure enough to pull the trigger on another card. It seems crazy to spend ~$150 or more on a used card on eBay or some other place where returns will be questionable when there are so many choices of brand-new cards.

I'm practically begging someone who owns a stock MacPro 1,1 and has upgraded to El Capitan in the last few days to tell me what currently available mid-range card ($150) will work. So much that I'm going to start a new thread.

iMatt -

I totally agree with you - blanket statements are frustrating and time wasting - your missive is accurate and well expressed.

To your point regarding video cards, I have been using a Apple-issue (two MDP ports on the back) ATI Radeon HD 5770 1024 MB. This has served me incredibly well, all through to 10.10.5 on my Mac Pro 1,1 to 2, 1, 2.66 dual quad core (upgraded processors). I think the problem with the 5770 under El Cap is that it won't handle some of the features of "Metal" (the graphics API). You basically won't reap the full benefits if you're playing games and need accelerated graphics.

An option that Ive been led to believe will be able to exploit all the "power" of Metal is the Apple edition of the Sapphire Radeon HD 7950.

I hope this helps in your search.

ok let's see...



I think boot.efi.Tiamo doesn't do any harm, but since this file belongs to Mavericks, I'd remove it - it's useless anyway.



PikeYoseFix is only for Yosemite. No point in installing it for El Capitan. Since you are already running 10.10.5 which is maybe the last Yosemite update, it might not be necessary. If you're still unsuccessful with 10.11 and a 10.10.6 comes out, then run the script... But you DON'T need it for 10.11.



I wouldn't do it - PikeYoseFix makes sure one specific version of the boot.efi is in place, and that's not the El Capitan one. So I would avoid it.



No. Just don't do it



/Library/LaunchDaemons/

Morpheo!

Great!! Much appreciated!!

So, you think there is no additional modification (besides boot files) by YosePikeFix that El Cap might be dependent on??

/Library/LaunchDaemons/ - I looked here and I don't have a YosePikeFix plist, but I do have a Tiamo:

file:///Library/LaunchDaemons/com.tiamo.macprofix.plist

There's something that tells me that there might be something about the YosePikeFix being deployed in in Yosemite that prepares it for the El Cap - but, that's a "feeling" based on limited knowledge of the nuts and bolts!

 

[sweetspud]

If you had used yosepikefix . It would have shown in I386 . I don't think it made a difference . Since it gets over written by el Cap install. After full install did you boot it up directly from the Mac Pro ?

Yup, I think I did put the drive back in the MP and try to fire it up after the El Cap installer completed its work.

I think I may have installed El Cap to the MD HD by setting the MP into Target mode - via firewire (maybe that's a prob??).

 

[sweetspud]

Hi Sweets - Did you use the latest macosxbootloader file for El Capitan? On Github here

I installed El Capitan from an eligible iMac, replaced the boot.efi files and - aside from my video issues - El Cap is working like a charm.

LMK how it goes ;-)

iMatt -

That's exactly what i did. Via Target mode on the MP connected to a MBP via firewire.

 

[nsotiriou]

No! There is no Tiamo version of boot.efi that supports Yosemite. Mine only!

Pike Hi,
I need your help with this update. I have the Mac Pro 1.1 and 5770 and so far with no problems I was using the previous boot.efi for Yiosemity. I read this thread and I decided to proceed to 10.11. All the guys here have attempt to upgrade with no problem. After the installation clean or with restore from backup I have a crash after 30 sec to max 1 minute. The system reboots and again the same story. I will give you the crash report if you can see something there. I went back to 10.10.5 and I will wait for your opinion to this matter.
Thank you in advance
Nicholas

the way i did it was using my mac b pro..via usb. i think ..not sure but the firewire method might give people problems .

If pIke doesn't come along soon, I think you should yank most of that USB gunk and just get back to keyboard and mouse. Same with Firewire. Even if El Cap wasn't known for USB issues, this would be standard troubleshooting procedure. Since it IS known for USB issues, doubly so.

 

[dcloud45]

Dum question why do we need to disable SIP?

Hi, I remove all the internal HD, also all the external USB devices and the crash remains as hell... Also I reset the PRAM. It is very difficult to explain because it is so simple. After a 30 to 45 sec the system reboots. First the mouse (Bluetooth) hangs and then there is a black screen with restart. It is strange that I can use the machine everywhere with no problem for the first minute.
Thank you

Continue removing/replacing things.

When you reboot next there should be a dialog box offering to send a report to Apple, say "yes" then open it and copy and paste to here.

 

[DevilDante24]

I installed El Capitan on an empty hard disk (connected externally) on a iMac.
After this I copied the boot.efi to the 2 correct folders.

However when I put back the hard disk into my Mac Pro 1,1 (upgraded to 2,1) I get the following error:
can't find mach_kernel.

I tried absolutely everything. I really hope one of you guys has an answer for me.

 

[MacVidCards]

"I tried everything" doesn't tell us anything.

Which post did you get the boot.efi from?

Did you see if it still boots in newer Mac?

What size is the file in all 3 locations?

 

[andsat]

Do you think the GeForce GT 520 would work? I am using the NVidia Web Drivers on 10.10.5 right now...

and am I understanding this correctly:

I just run the normal 10.11 installer and do the usual EFI file replacing? because I've done that a hundred times (whenever Yosemite had an upgrade)...

Hello,

First of all: thank you for helping to keep the Mac Pro 1.1 running!

I have a Mac Pro 1.1 with ATI Radeon HD 4890 running Yosemite on an SSD.
Luckily I bought a new one for El Capitan. But I can't get it to work.

I created an El Capitan USB installation stick with the procedure in this thread and installed over my Yosemite on the old SSD. Installation worked but after replacing the boot.efi with the new one from Github it does simply not boot but stops with a Kernel Panic. I used the "grey background and logo" one for legacy hardware as it is called on Github.

I have attached a file with the kernel panic during booting.

Do you have any idea what is wrong and what I can do?

Thanks a lot!

 

[MacVidCards]

I seem to recall that the 4890 requires a driver fix usually.

this boot.efi is the ones i use http://piker-alpha.github.io/macosxbootloader/

 

[yuser]

Yes, I use the same one boot_grey.efi from there (there is a link "View on GitHub" --> I got it from there).

The driver fix was usually needed to get the QE/CI graphics acceleration but it did not prevent the machine from booting itself (at least this was the case for Yosemite, Mavericks). Don't know what is different this time.

What is size of boot.efi in all 3 locations?

looks like one got missed

 

[sarthak]

Still seems like a risky install. Will continue holding off until (hopefully) it becomes a click and update.

It is a simple one, biggest issue is operator error.

Hum ...try using the non grey . Efi

 

[dcloud45]

Am doing a second one. On another HDD same way I did the first one. See if I hit twice.

Already tried the non grey but still the same.
I am just cloning back from my new SSD with Yosemite to my old SSD... Give it a new try...
