Need data.

To everyone interested in this project:

[P]eople must be aware that [this and other] interim future versions are NOT intended as a replacement for the official repository versions. Until further notice, those of you who want to use Pike's boot.efi ought to go to http://piker-alpha.github.io/macosxbootloader/ and download either the "black" version or the "grey" one, according to your particular preference (the change is purely cosmetic; otherwise, they are exactly the same; the choice is irrelevant as far as the operating system is concerned). Pike alone will decide when such repository versions will be updated with a newer version.

Please, notice that the [enclosed and other] upcoming experimental versions might contain bugs that could cripple your ability to boot your old Mac. So, unless you are absolutely certain of what you are doing and know how to reverse such undesirable situations, KEEP AWAY FROM THEM. In general terms, [these] versions ARE NOT FOR YOU!

ok thanks. Andy thanks but the issue is I won't be able to see the startup chooser with my flashed card. If I can select a CD to startup with, or if as Peter suggests the system should eventually find the original startup disk then I should be fine.

I presume therefore the startup disk selection is an order of preference and if the chosen one is not there the Mac starts trawling through the other volumes to find one that might work?

thanks

If it s a flashed 5770 it should actually show a boot screen via a dvi to vga adapter. So if you have a display that has vga port it should work.

Florian has made strides in 5xxx flashing, may be possible to re-flash and get DVI boot screen. See netkas forums in "port mapping" thread.

Hello,

--8<----

Is it possible to use the same procedure I've used to install Yosemite (from Mike Hennessie) to install El Capitan on my machine ?

This is how I and many others (who do not have supported hardware) have been doing the entire time.

I highly recommend taking the time to hand-tool one's own installation--completely--for the understanding of the process and how these thing work.

Extremely educational, to say the least.

Props to @Hennessie for continuously reminding us of the things we should already know.

I ordered the original MP 2006 in November of the same year, and it's working even better today than it did on first-boot.

Yose is fantastic, and El Cap promises many more years of the same.

If it were not for Pike, I'd still be with Mav (quite happy, I must say), but time rolls-on, and things change…many, many thanks to Tiamo and Pike for allowing me to be a part of the Future.

*props*

Odd how I missed that in the instructions... I had thought that only TWO files needed to be replaced before putting the HDD back into the Mac Pro and booting. I'll need to check out exactly where that third file goes, as I'm not quite sure (and I have also heard people talking about this 'Recovery partition'--almost with angst).

While I have never done it manually before, I DID go through putting Mountain Lion and Mavericks (and back) on this very Mac Pro, so I'm sure I can do the same with El Capitan. I have a 2009 MBP on which I can complete this, through TDM.

As for back-ups, I may leave my SSD as my boot disk AND storage disk, as I already have a secondary HDD that serves as my Time Machine back-up disk. Should anything go wrong, I could simply clone the stuff over. If I want to downgrade, I can either keep a third HDD with a clone of my Mountain Lion user on it, or simply run my Mountain Lion SFOTT installer over El Capitan to downgrade; it seemed to work when I wanted to go back to Mountain Lion from Mavericks.

3rd spot is Recovery partition. More important now then before to have it available.

Let's assume that I can't/don't make one... is "Then, after installation, copy Pike's EFI32 boot.efi to that drive's /usr/standalone/i386 and /System/Library/CoreServices/ directories overwriting the stock Apple EFI64 boot.efi and repair permissions. That drive should now be bootable on a 2006/2007 Mac Pro, although sometimes it still may need to be blessed in the 2006/2007 Mac Pro." all I need to get this working? For the heck of it, I did try this with Yosemite, but it wasn't able to boot. I simply moved the boot.efi to those two folders (replacing the old ones) and tried booting the Mac Pro. Maybe it needed to be blessed? (Also, how do I repair permissions? Apparently that was removed from Disk Utility, right?) How do I bring up the prompt in which I can bless the Mac Pro's HDD?

(Sorry for the bombardment of questions... I have only worked with SFOTT. Planned on waiting for the release of El Cap, rather than experimenting with the betas.)

Yeah, that should do it. But I have never been even mildly clear about how people manage to have as much trouble as they do.This is like "falling out of bed" easy. And yet there are pages and pages of hand-wringing and claims of days lost, data lost, lives ruined, etc.

One thing I don't think people get is that a Mac Pro can have any number of OS's and boot disks inside. I also don't think people realize that Disk Utility has a function similar to Carbon Copy Cloner with "Restore". So there is never any reason to EVER have any Data (or favorite OS install w/licensed software) at risk. NEVER EVER.

A 1TB refurb drive can be had from Newegg for $30. A Mac Pro can hold 6 @ HDs with ease. If you can't fit your Boot OS into 1 TB you probably take a steamer trunk on 1 week vacations. So, be smart. You have an OS install that has everything you want running like greased lightning but you want to move it to a newer OS? Create a restore image on a blank HD. Or just clone it and keep the original in a safety deposit box (or just not in your machine)

So, cloned/imaged boot drive is safe. YOU NO LONGER HAVE ANYTHING TO WORRY ABOUT.

Mix PPC Extensions from OS 7.5, Reinstall the Chooser. Do whatever you want to the OS and know you can just get right back to Point Zero with a few button clicks while you go make some coffee. So, now that we have removed any and all things to worry about, let's just pay really good attention to the things written by the people who have it working.

I personally think that the "build installer form real one in package editor" route is for people who have lots of time to waste and enjoy a Rubik's Cube that is missing a few panels. Someone you know has a Mac that runs 10.11 natively if you don't have one personally. Use Firewire, or SATA to USB or whatever, just get a full, solid install done on another machine.

Replace the 2 crucial boot.efi files.

I would recommend also doing the Recovery Partition. I wrote an easy way in the Mac Pro section.

I honestly and truly believe that some people form mental walls in front of themselves to keep life interesting. I awoke yesterday to 20 texts from an enraged customer. "Your card has an error and now my computer won't boot and I have a project due tomorrow and you owe me helping me" was one of the nicer ones. After hours of all caps screaming texts and emails he finally admitted that the issue had started RIGHT AFTER updating to 10.10.5, but only after I dragged it out of him.

He had to know, he hits "update", the 10.10.5 downloads and installs, computer won't boot on next boot. Nope, wouldn't admit that for hours of anguish until it got dragged out of him. Me, I'm thinking that it was such an obvious "cause and effect" moment, but he insisted there was a card fault, etc, etc.

Long story short, he wanted the fault to be mine so he wasted hours of each of our lives when he had to know somewhere in his head that IF IT STARTED AFTER UPDATE, UPDATE CAUSED IT.

So, I think some of the people who have been plagued by issues cut a corner somewhere. Hennessie says "Use a Blue USB stick" and they think to themselves "Well, my orange one hasn't given me trouble before, I'll use that and not mention it" and then come here whinging about "No Boot" symbols, and flashing question marks,and reboot loops. Ever since Tiamo did first boot.efi I have made multiple ones, never any issue. I can not for the life of me understand where all the issues come from.

Make a backup, and I don't mean copy a couple files elsewhere, i mean a disc image of boot disk, or an entire 2nd disc that functions exactly 100% like the one you are about to use/risk/ruin.

Pick one person who has made it work and who posts here a lot, and follow their posts, just theirs. Don't mix and match advice from multiple methods. More then anything, you need to realize that IT CAN WORK. You aren't climbing Everest for the first time. You are walking up a well lit path in a heated space suit with a guide rope, a GPS, and Helicopters overhead. If others have done it over and over, you can. You just need to NOT DEVIATE, no shortcuts.

I have always been a firm believer that if someone comes on a forum and says "I just used "Product A" and ran "Software B" and got "Result C" that they did it. People have very little reason to come lie about such things.

At this point I would wait 24 hours and see what results look like with the Final release. I'm sure other people will test before I do, I'm on West Coast and get up late. (And I'm going to be up late tonight) So, some of the Gurus will post what they did to get Final El Cap running. Do it.

Yep, I am all ready and set with a separate HDD that I have my info cloned to. I have never booted from a Time Machine back-up, though... I have more experience working with CCC. Anyway, if I want to be extra safe, I may have a spare HDD on which I can have my cloned system (before going to upgrade to El Cap), and then stuff that HDD in a drawer. I personally HATE the noise coming from my HDDs, whether new or old. The newer ones are quieter, but I'd still rather keep things as quiet as possible, as my 1,1 Mac Pro seems louder with 1 newer HDD than my brother's 2008 Mac Pro is with 4 newer HDDs.

I noticed those issues as well that other people had. TBH, that turns off many new-comers. I have gone through the process, as mentioned, but with SFOTT. As easy as this is, it's new to me and many others. I think it just looks way more intimidating than it really is, and I tend to overcomplicate things. I will be alright, though, as I know what I'm doing.

Now we'll see if my HD Radeon 6450 runs the graphics okay (or still boots the system, because this non-flashed card works in Mountain Lion--but who knows if it will work after the update?). Still, I'm on the hunt for a nicer passively-cooled card that will work w/o being flashed. I don't want to go through the flashing process, nor do I want noise; so, I am looking for a passively-cooled card (just like my Radeon 6450 is) but better. Someone mentioned to me the passive GTX 750ti (or something of the like), but I can't be sure if he himself has ever tested it inside of a 1,1 MP. Do you know of any random, passively-cooled cards that will work out-of-the-box? This 6450 is a dream, in that regard, but it's not as powerful as my 5770 was. (Sadly, the 5770 is temporarily out of commission. I installed an Arctic S3 passive cooler onto it, only to realize that the thumb screws on the bottom of the card obviously cause it to not be able to fit into slot #1. I then snapped the screws by mistake, so now I'm just looking for a card that's already passive and somewhat matches the performance of this 5770)

Anyway, I digress... I'll see how the full release of El Cap goes. I am also on the West Coast (in fact, I'm in LA--only about a half-hour or so from you), and I have school and homework! ;-) ) No matter, though. School comes first, then Mac Pro upgrade.


Thanks for your current help, BTW. Sorry if I possibly triggered you to write all of that. It must be annoying to have to explain all of this to newbies all the time. I myself was just confirming the steps. It IS really easy, but I was caught off-guard by all the people who were having issues, and that made me feel unconfident in my own endeavors to update my Mac Pro.)

Restricting search. Even more restrictive (__TEXT,__text only).

PS I'll be back in about one hour.

Apologies if this is a little off topic.

I have a Mac Pro 1,1 2006 running Yosemite on an SSD in the optical bay (thanks Guys!) using Tiammo's EFI and Yosefix. I have a flashed ATI 5770 GPU so obviously no boot screen until finder.

I understand how to install El Cap on one of the Mac Pro HD's using a friendly iMac and copying the EFI files etc then moving the disk back to the Mac Pro. I would then select that HD and restart. My plan would be to install it on an external firewire HD over a copy of my Yosemite boot SSD, then move the firewire disk to e Mac Pro and select it as a startup from Yosemite.

My concern is if I muck things up how will I select the original SSD startup disk as I have no bot screen. If I removed the non functioning firewire startup disk would the Mac eventually search and find the original SSD with Yosemite and restart?

Or should I leave a copy of Lion somewhere on the system in case I need to replace the original GPU and boot to that?

Many thanks!

Hi rkanaga,

You might want to try using a DVI to VGA adaptor and cable and using a VGA supported monitor/tv as this might show you the boot screen. Does for me.

Cheers

Great Thanks, I have an old VGA monitor lying around so good to have this as a backup plan!

Thanks for all the advice

Is El Capitan a click and download, safe upgrade if you have the PikeYoseFix installed?

Just got released on MAS but, given the multiple crashes I've had upgrading on the previous releases of OS X, I'm not going to be among the first to attempt an install.

PS could someone please explain how to bless the boot volume? Specifically how to find the volume name for your disk that you need to insert in the terminal command?

I presume the command is

bless --folder /Volumes/YOURHARDDRIVENAME/System/Library/CoreServices --bootinfo –bootefi

and say if my HD is "SSD 480Gb" then you replace " YOURHARDDRIVENAME" with "SSD\480Gb"?

Many thanks as always

One further thought. To say mucking with SIP, when it comes to update time, could you simply run the update, then boot from a bootable CD (Say an old Lion install disk, by holding C), and then from there replace the boot efi's on your main boot disk before rebooting again? (assuming you keep a copy of the modded efi's somewhere on your HD)

hi all

I just created a USB Installer Disk and replaced the boot.efi with Pikes latest macosxbootloader.
All seems to be good with booting on my Mac Pro 1.1 with a flashed Radeon 4870.
I stuck now on the installer... he shows me always "OSX El Capitan is already installed"

It looks like Apple have a online check in the installer for verifying supported Mac models.
