The only chance I see would be for Pike to "inject" an emulation layer within boot.efi that will automatically translate all SSE 4.1 microcode calls to the relevant instructions that the older processors can understand. If that were achievable, it wouldn't be the end of the matter, since performance issues might be relevant. In other words, would such emulated operations be fast enough to justify running macOS Sierra on such obsolete and increasingly slower hardware?

You're right ... if so it would not make any sense

That has to be done in kernel, cuz only kernel can control unexpected instruction faults.

But MacPro 1,1 is actually too old. There is no USB 3, no Thunderbolt, slow PCIE bus, old display technology.
We can add extra hardware to help, but the life time of power supply, ram modules are dying.
I have ram modules replaced from time to time.

I think It is time to let it go.

Sad but true. My 1,1 has given my almost 10 years of solid service. That's way more value than any other computer I have ever, or probably will ever, own. It might have been on the expensive side but over the years it's worked out to be a bit of a bargain.

I have recently replaced the Pro with a 12" rMB, which performs decently for what I was using the Pro for these days and is a tad more portable!

I mean usb and display port can all be added though pci expansion, I still think that modding the uefi to run sse4 might work like I said on the last page anyway, it's just a matter of someone translating it into a uefi update.

I am just getting to the Mac Pro party having picked up a 1,1 last week. I had been planning on upgrading it and running Sierra but i guess the wife will have to live with El Cap (it's not like she likes change anyway :p). This reminds me of the days of running Panther on my beige G3 where applying an update ran the risk of rendering it un-bootable.
Still, it's a nice machine, gonna max it with SSD, 5355s and a GTX 670. It will have a dignified retirement.

:)

Besides, being "stuck to El Cap" doesn't necessarily mean retiring it. As long as mine meets the system requirements to run my software, and as long as it gets my work done, I'll keep it. When it can no longer meet *my* requirements, I'll find a nice spot in my closet near my beige G3, which for some bizarre reason, I still have ;)

I got my 1,1 last month to experiment, develop, and render on. I hope Piker finds a way or I'll have to get a 3,1 to keep developing

My problem is that the "system requirements" of my wife are nebulous and ever-shifting :rolleyes::D The beast should do her fine until it's time to pass down my iMac.

Just upgraded mine to 16 gigs of ram and a 660 ti. (I left the regular card in so I can see boot screen too) and mines been running great! It has so much potential for such an old computer and it would be sad to see it finally being put down. However it'll probably support Windows for a long long time, so that's a plus.

How does that work, do you have dual monitors then?
That's how I do it, I bought the cheapest monitor I could find on eBay just for the boot screen and menus (Plus you can extend the desktop on it a bit too but I haven't used the other desktop for anything but more wallpaper). But you could also buy a monitor that accepts two inputs and switch between the two

Eactly what I do too.

Hey guys, running a one year old OS (El Cap) on the 2006/2007 Mac Pros is not the end of the world :) If it is not capable running the Instructions of Death then we fiddle with El Cap until the box passes by...

I do not understand why on VMWare updating Sierra to El Capitan I get kernel panics (MacPro 2.1)... SSE4.1 also affects the VM?

That was probably to be expected. VMware Fusion and similar applications do not emulate a processor. In fact, they use one of your Mac's internal processors and pass the microcode instructions on to it. In other words, if macOS Sierra calls a microcode function that your processor can't interpret, the machine, whether physical or virtual, will crash.

I still have two beige G3 MiniTowers which is what I used till my Sawtooth G4. All 3 still run well, just haven't used them in better part of 5 years. I bought my 1,1 brand new in late 06' which was the upgrade from the Sawtooth. I recently picked up a 4,1 by trading some surplus machines I had to a reseller/recycler. My 1,1 will probably stay on El Capitan being it has 24GB of RAM, boots off of a 120GB SSD and is getting a pair of Xeon 5355s as soon as I get the chance to sit down and do it. Right now it is also my server running the Open Directory and Caching Service for my home network. It'll be awhile before it's retired.

I too have a similar Mac collection - G4 Sawtooth and Performa 6200 are in the attic now though. Mac Pro 1.1 (2.1) with new CPUs and El Cap will probably be around for a while unless it breaks, as Adobe CS6 in likely to start misbehaving on the newer OS and I refuse to be forced into Adobe's rental scheme. There needs to be some huge shift in both hardware and software to make replacing this set-up a viable proposition financially.

My 2006 Mac Pro is probably the best computer purchase I'll ever make. Going on 10 years old, and it still runs circles around my work-provided iMac (which they replace every other year, with a new but bottom-of-the-barrel model). The Mac Pro is still a joy to use.

I just popped a couple of 5365 CPUs in there, which I got for a song. Doing that little upgrade project reminded me of just how nicely engineered these machines are.

El Capitan may be the end of the line in terms of OS (we'll see), but I anticipate using this machine for years more to come.

Yeper Ill go further then that on the MDD some panther updates would hose the system so I would check on xlr8yourmac before updating

Actually the upgrades went well, it's now flashed to 2,1 and running dual x5355s with 12 GB memory and the GTX 670. I cloned the wife's SSD to an HDD for testing an everything looks good. *Except* i cannot get it to sleep. I check pmset and everything looks good. The screen goes off but the Mac keeps running. Have you guys seen this and managed to deal with it? I'd really like such a beast to be able to sleep when idle.

ETA: i have already tried PRAM/SMC resets

This is an old app that I've used for years when I encountered problems with sleep.
It uses a brute-strength method to force sleep when all else fails.
Might be worth a try, can't see where it would hurt anything.
