Resolved 2006/2007 Mac Pro (1,1/2,1) and OS X Yosemite

bumping thread for a hopeful answer...as it normally doesn't take this long for someone to respond

I don't have experience of Nvidia cards but have you checked this is compatible with Yosemite? Some of the Radeon cards aren't. Is you card a Mac version? If not, has it been flashed? I believe this can be more difficult on Nvidia cards. If not, are you sure you are just not just experiencing the lack of boot screen? Was the card working under your previous OS - if so can you boot into that to check it is still working? have you tried checking output from any other ports?

Perhaps a stupid question, but have you / do you need a separate power feed to the card - some Radeon cards use 2 cables + the PCIe slot to get enough power.

There is some info on this card in a Hackintosh setup requiring messing with kext files but not sure if this is applicable to your issue.

 

[cms062407]

The card works fine in my windows machine.

It does take a 6pin power feed, it is connected.

I am not 100% sure if the card is compatible, but I googled it before trying it and people seem to have made it work.

Do you have several hard drives with different OS installed? You could pull the other drives so it forces the Mac to boot into Yosemite - without a boot screen it is difficult to choose manually. What card were you using before the update?

I was just using the stock 7300GT.

I only have 1 OS installed in RAID0.

Now, I did just press the "diags led" button on the motherboard with that GTS 250 in...and the "GPU present" LED is NOT lit..

I then took out the 250 and put the 7300 back in and now the "GPU Present" led IS lit.

 

[Ant3000]

Not able to help on the LEDs, sorry. On some Radeon cards there is sometimes a switch to select either the PC or Mac ROM - not sure if yours has that. Was it sold to you as being a Mac card with boot screens - I would guess if it works OK in a PC but not on a Mac it is probably a PC card. What port are you connecting your monitor to - DVI?

Just looked up a GTS 250 for sale - flashed for Mac and it states "VGA/D-Sub not supported" the fact your monitor says no signal makes me think you may be using VGA as I have never seen this message on my Mac using DVI.

I am using a DVI, yes.

I am going to try a HDMI connection.

HDMI same thing...display shows "no signal"

Hello Hennesie2000,


I had reinstalled Yosemite, but now I don´t see the letters just the grey screen with the apple logo and no spinning wheel, I can´t pass that stage. I have a genius wireless mouse that I use¨The USB device to connect the wireless mouse is attached to a USB port on the back of the monitor¨, I also have an internal bluray that I had added some time ago.

I had never ecountered any issue upgrading previous OS versions with these devices on the computer. What might be the isse?.


Thanks.




=Hennesie2000;20287895]Do you have any FireWire devices plugged in?

I have this same issue but with a iMac late 2006 model

This may help if you read all the replies on the thread linked to.
A quick bit of research points to this card only working when flashed - where did you get the info it would work in your Mac?

With Yosemite? I didn't think the 2006 iMac was capable of running Yosemite at all - the 2006 Mac Pros can with a bit of work but not the iMacs of the same era. Can you clarify which Mac and OS you are using?

has successfully running Lion - Mavericks - Yosemite - ElCapitan on my MacPro1.1 sidebyside;
but now when i want to make a fresh install of Yosemite through USB installer on a fresh HDD it always says that i have Yosemite already installed, even if i have no HDD with Osx attached.Any Idea why so?

This is the best ElCaptian method for MacPro available i guess
(OPEN LINK ON YOUTUBE - THERE IS DMG.FILE FOR DOWNLOAD)

is ths pre-patched version still available?

thanks


ps. i still prefer Mavericks over all the other especially because you can run Quicktime 7 Plugin on Safari with clicktoplugin which is still aewseome

 

[Ant3000]

There is more info on the El Capitan thread on the pros and cons of this installer and alternatives. Posts in the last couple of weeks as well as post no 1 give good info.
Have you performed a Spotlight search to see if there are any refs to Yosemite still on your Mac. I know if you have a copy of Yosemite in your downloads folder you cannot download the installer again, so you may have a similar conflict perhaps.
Are you trying to use the same installer as before? If so this will not work a second time without blessing the system folder - info on the El Capitan thread.
FWIW I used the pre patched Yosemite but used Pikify to build an El Capitan installer - not the one you listed above.

 

[mrkapqa]

could you share the pre-patched? I made install USB with SFOTT and manually, made all the steps (supposedly) - but then after the reboot and after the MacLogo comes up - it says - Mac OS X Yosemite is not installable as OS X is already installed or so - even after i remove the Mavericks which is on SSD ... this is really strange to me.


(EDIT)

i got it installed now - had to install it directly on the HDD - seems that from USB to HDD something did not work out as desired. cheers + happy computing!

 

[Ant3000]

Glad to hear its working. I use SFOTT with Mavericks but never got it to work with Yosemite - for anyone else the prepatched installer of Yosemite is linked to on Post 1 of this thread.

Hi everyone.

After a few weeks of successfully running Yosemite on my computer I am noticing it has become a bit sluggish for no reason. Even booting takes much longer than it took at the beginning. I haven't clocked it but it is definitely slower. Also now I am in the middle of a 10+ min holiday-pics-importing process which definitely shouldn't take this long. Any ideas? Is there anything I can do about it?

Many thanks!

 

[Ant3000]

I doubt it is specific to Yosemite on a Mac Pro 1.1 so use the usual trouble shooting techniques.
Have you checked your RAM is all showing in system profiler and that your HD is good? Are any apps running in the background (check in Activity Monitor) that may be hogging resources? Resetting PRAM may be worth a try too.

Wow! I'm so glad I found this forum! I recently picked up a 2,1 MacPro (3.0 Ghz/8 core), 8800GT video card, 12 GB RAM, and 750 GB of HD space ($200). My son has been using the box under OS X 10.7.5 and I decided to test my hacked upgrade skills. Took a little looking around but I found the option for installing an unsupported version on a secondary HD on a box running Yosemite, replacing the efi files with Pike's, repairing permissions, and blessing system. I'm now able to boot into 10.10.5 by holding down the ALT key upon reboot and selecting the Yosemite drive. Minor annoyance for something that was so easy to do. I do have a couple questions:
1. Apple wants me to install the latest Security Update (2016-004). Is that a problem?
2. Because I installed Yosemite on the external disk on a different hardware box (iMac), is it advisable to wipe the kext cache files that may ID the iMac and reboot so that the hardware cache files rebuild, or will this break everything?

Thanks for all you do here. It has really made it easy to upgrade this awesome box.

 

[Ant3000]

I think the security update should be OK but you could install PikeYoseFix to protect the boot.efi files and be sure. Why did you install on an external drive? with 4+ drive bays you could install on an internal drive or SSD - even from an iMac using Target Disk or by building an installer using instructions on this thread. Usually, selecting startup disk in system prefs is all you need but wonder if the drive is not being picked up by the Mac at boot if it is USB powered? I have SSDs installed and have both Yosemite and El Capitan running well.
I don't know about the kext files but usually the boot.efi files are all you need to replace if doing it manually - as I understand it anyway.

 

[BRnPA]

Ant3000 - Thanks for the clarification. I'll checkout PikeYoseFix. Long story on the iMac (different physical location): Long and short of it is that Carbon Copy Cloner was able to clone 10.10.5 to my internal drive from the external USB drive and I applied the boot.efi fix. After blessing the CoreServices dir, with the correct arguments, booting is much better. System is very stable and fast.

I (finally) successfully updated my Mac Pro 1,1 from 10.6 to 10.10 last night. For the most part this guide worked, but I have a few tips for anyone having issues:

• you must have upgraded your video card - the stock ones will not work in Yosemite. I luckily had a Radeon 6870 installed using this guide, but before I did the machine would crash right after logging in.
• In my opinion the easiest way to install Yosemite is to use another computer and access your Mac Pro's drive either by using Target Disk Mode or by removing the HDD and using a dock. That way you can install OS X using the stock installer. After that you only need to replace the boot.efi file in its 2 locations and updated PlatformSupport.plist.
• For what it's worth, I am using Pike's latest boot.efi (v3.1)
• I have not tested Recovery Mode yet, but it should work since I mounted it and replaced boot.efi and PlatformSupport.plist on it as well.
• This guide is very helpful for when it comes time to replace boot.efi as it walks you through where to find the file and how to give yourself access to it.

My apologies for the very late reply, this is a computer I don't really use that often and I've been away from it for a long time. In any case, I have checked RAM and HD, as well as Activity Monitor and nothing stands out, everything looks ok. I just reset PRAM and nothing. It takes a reaaaaly long time, I would say around 45 seconds for the load bar to crawl to two thirds, then the screen blips and switches off briefly and after that the system loads in 5 secs. It is quite odd....

 

[Ant3000]

I think there was a similar slow down reported on El Cap thread that was possibly a failing HD - despite the fact it may be reported as OK in Disk Utility, it could be the issue if other things check out. Have you another Drive - or even better an SSD you could use to install again?

I can try to get one, I suppose, but it would be a bummer, I got this SSD specifically for this, had Yose installed for less than two months when it started happening and quite little workload. Drive is around 90 percent empty....

 

[Ant3000]

I assumed it was a HD - have you enabled TRIM?
There is more info here... http://www.howtogeek.com/222077/how-to-enable-trim-for-third-party-ssds-on-mac-os-x/

I had Yosemite on a Crucial MX200 and enabled TRIM with no problems.
