The problem with the early Mac Pros

is that Apple built them with a 32 bit EFI that is incompatible with versions of OS X newer than Lion.  The machine is a true 64 bit machine, does run 64 bit software just fine.  Unfortunately there is no 64 bit upgrade for this EFI ROM, and even if there were, the chip is soldered to the board.  I did find a work around I'm gonna try on a spare disk this week-end.  It involves replacing the boot.efi files in the installer for Mavericks with a modified one, and disabling the hardware checker in the OS installation program.  It'll probably work, but when Apple releases a new level of the OS, it will probably replace the modified files and break the system.  Not good.  Just going to have to give it a try and see what happens.
 
I got a new MacBook Air last week, I love it so slim and lightweight and what struck me was that it's completely silent no fan noise. It's remarkably quick with a solid state hard drive too boots up in a few seconds, I have installed Windows 8.1 (takes some getting used to coming from Windows 7!!!) on it too with Boot Camp so I have the best of both worlds. I also have an original MacBook in Black that I got in 2008 it runs OS10.6 and XP Pro with Boot Camp and it is still going strong and I have an original Mac Mini G4 that I purchased around 2004 it's like a tank just keeps on going!!! Macs are expensive but in my opinion they last a very long time, my Dell XPS laptop that I got in 2010 needed a new motherboard and keyboard luckily it was still under warranty but when the faults occurred I'm about to give that to my parents now I have my new MacBook.
 
Well, I got the iBook G3 and I installed 10.4.11, and divided the drive so I could install OS 9. I'm posting this from the Classilla browser on OS 9.2.1 right now. Its a very diffeent and interesting OS from what I'm used to on a Mac, I barely remember using this backin elementary school.
 
I think the cutoff for OS 9 boot ability was in 2003. The mirrored drive doors PowerMac G4 kept it til it was discontinued. In OS 10.4.11 and older on PPC Macs you can run in "Classic Mode" which emulates OS 9 and runs most of its applications. You can download an emulator on Intel Macs to run it if you want.

I might have found a Mac Pro for $75 with a bad video card. Well see today if it works out.
 
If that is true, get it. Mac video cards are expensive, but if you have a PC with the correct video card connector, then you can flash the Mac bios to it....

Maybe I'm thinking PPC macs... Hopefully not.
 
Mac G3 and G4

We used to have the old Mac G3 and G4 all in one units for the art users and those were true workhorses.

But I have had not too good experience working with the A1181 and A1342 white Macbook laptops in my school district. I am the building tech so have to come up with fixes whenever these go sour. Common problems we have experienced are broken magnetic power connectors that were recalled on the early 1181's, to units that will not charge to locked up keyboards requiring PRAM resets to certain software incompatibilities with our Smartboards. Also annoying are the built in batteries on the 1342 models requiring Apple to change them out and the lack of USB ports. The interesting thing is that we have the same number of Mac laptops and Dell E6400 laptops being used by the same students and teachers. Both are of the 2008-2009 vintage. I now have a pile of 15 dead Macbook laptops whose cost to repair far exceeded there value and only one Dell that was dropped and smashed. Every other Dell is still in use with Windows 7 and still run reasonably well. I am impartial to either OS or company as they are both made in China and each have there pluses and minuses but the newer mac laptops just do not seem to hold up as well in daily use from what I can see.
 
If I get it, so long as I run 10.7 or newer I can use a stock Nvidia card and it will work with the OS, but I won't get the boot screen or any tin before he driver loads. I'd buy a PC card that I could eventually glass though. I flashed the card for my G5 because it didn't come with the ROM I wanted it to.
 
Still... It's only $75. That's a pretty damn good deal.

I'd love to find a Mac Pro 1,1 to replace my current secondary iMac (Core 2 Duo 2.16ghz, 2gb RAM, Early 2007) as it's starting to bite the dust and running a Minecraft and Terraria server isn't doing it any favours.
 
My Mac Pro is a 1,1

and I bought it about 6 months ago for $700.  It has 2 dual core Xeon processors and it came with a stock nVidia card, 4 GB RAM, 250 GB HDD.  I upgraded the video card to the one I posted in the link in my last reply, and it rocks.  I get the power on chime, the gray boot screen and all.


 


I also upgraded the RAM to 16 GB and added a 128 GB SSD and a 1 TB HDD.  Installed OS X 10.7 and apps on the SSD and Windows 8.1 on the 250 GB HDD in a boot camp partition.  I also installed Mavericks in a VM under Parallels Desktop 9 and it runs like a champ.  Funny I can't install Mavericks natively, but can in a VM.  Goes to show how unfortunately Apple tries to obsolete older hardware by deciding which machines newer software is "allowed" to run on.
 
I ended up passing on it. The thing that killed it for me was that it didn't have much RAM, and the 2006-2008 models use expensive RAM compared to the newer models. I see 2009 ones going for $500-700 and I think I'd rather save up and get one of those.
 
OS 9 will not run on Intel based Macs.

Thanks for letting me know Joe, I've installed Virtual Box and have tested with an old Win XP Pro volume license I have. I'm very impressed with it for a free bit of software, I'm going to try OS 9 and install it. I wish i'd been old enough to have been able to afford the old crt iMacs when they where available I loved the look of them so much!
 
Where there is a will ...

There is a way!


 


I got Mavericks installed natively on my old 2006 Pro, and it runs great. Everything works, and now I can easily get a few more years out of it.   Apple doesn't support running any OS newer than OS X Lion on my model Mac Pro, and in the installation program for Mavericks, it explicitly checks the machine's model against a list of supported models.  If your machine isn't on the list, then it refuses to install.  I knew I could install it by connecting my machine to a compatible model with FireWire, and install it that way, but it still wouldn't run because the EFI built in the machine was 32 bit, and Maverics requires a 64 bit EFI to run.  Well, after searching the internet, I came across several methods of performing this install using an alternate bootloader called Chameleon, but that install was pretty cumbersome, and required a small dedicated drive for the bootloader and installation software.  Reviews I read indicated that though it worked, it had issues.  I didn't want to go this route, and was considering buying a newer model that would support Mavericks directly.  Then I read an article about installing on my model without having to jump through so many hoops, and from revies, it was stable as a rock and didn't break anything.  All I needed extra to do it was a replacement BOOT.EFI program to replace the one in Mavericks, and I would be good to go.  I downloaded the new module and below is how I did it:



On my Mac Pro I have three internal drives:, 1 250 GB HHD, 1 128 GB SSD, and one 1 TB HHD.  I wiped my 250 GB Boot Camp volume, since I run Windows in a VM, and didn't really need it. Then I connected my Pro to my MacBook Pro via FireWire and booted the Pro into Target Mode. My MBP is Mavericks compatible, so I booted it and my Pro's disk volumes appeared on the MBP's  desktop as external drives. I ran the Mavericks installer and <span class="text_exposed_show">used the 250 GB volume as the destination drive. When the installer finished, and wanted to reboot, I made sure the MBP booted from it's own disk instead of the newly created volume. I replaced a file called boot.efi in two locations on the new volume with one that was modified to work on the old Pro. Then I shut down both machines and rebooted the Pro normally making sure to boot from the new Mavericks drive. It came up and runs like a champ. I used Migration assistant to copy all my settings and apps from my Lion disk, and it all runs perfectly.

Then, being a glutton for punishment that I am, I decided to combine the 128 GB SSD and the 1 TB HDD into a Fusion drive. After I successfully created the Fusion volume, I used Carbon Copy Cloner to move Mavericks from the 250 GB HHD to the Fusion volume. Now it is REALLY fast. I kept the old Mavericks disk to use as an emergency boot device in case of emergency.</span>
 
I heard about that listening to Rush yesterday. I guess a lot of people were all annoyed and whining because Apple didn't make a big deal about the whole thing. Personally I think keeping it quiet until its fixed is better, if they'd have made a big deal about it before releasing the fix then more people would know to try and take advantage of it. I always install updates soon as they one out tho, I never understood the people that put updates off forever. I also always upgrade the OS to the newer version as soon as I can too. I don't plan on upgrading my Windows PC to Windows 8 though, I really don't care for the new interface in the least bit, they just made it harder and more aggravating to use, they really had 7 figured out pretty well, the best part of 7 in my eyes was how easy it was to disable that annoying UAC that constantly popped up and harassed you, it was kind of difficult to kill in Vista but I know how to do it and believe me I did.
