Then to install change ownership and bless a folder. You need to know terminal commands to change the file flags because the new boot_efi has to be removed. ![]() Not bad for a dinosaur down side but guys have done it both ways is to have a partition or drive with 10.7 to install the modified boot_efi or as I do remove and put it in a dock. I am using a Nvidia GT630 2GB card (peecee) so no boot screen till logon. The darn thing from chime to log on is 15 sec. I've updated mine with 250GB SSD drive for boot up used CCC. Unless you can identify specific benefits to going with Lion, or are willing to take the risk of hacking the machine to run a newer OS, I would think Snow Leopard would be the best update here. Lion supports some newer applications that Snow Leopard doesn't, but Apple seems to be trying to bump everyone up to Mavericks for iLife, iWork, & Aperture. Since you are using one of the earliest Mac Pros, and were earlier using a PowerMac G5, you might well be using many of those. Snow Leopard is the last version of Mac OS X that has support for running PowerPC-only Mac OS X applications. But keep in mind that neither Mountain Lion nor Mavericks will run on your machine without hacks. Mavericks is a free Mac App Store download and is not hidden away in "you can only find me if you know the right way to look for me" limbo like the others. I don't know if the Lion download is old enough to install on your machine Apple may have updated it to the latest Lion release. Lion (10.7) and Mountain Lion (10.8) are also still available, as Mac App Store downloads, for $20 each. You need Snow Leopard even if it is not your final destination, as 10.6.8 is the first version of Mac OS to include the Mac App Store. Apple still sells it on DVD for $30 it doesn't show up if you casually browse the Apple Store pages, but if you do a search for it, it is there. If something goes wrong, you may be left on your own for troubleshooting/fixing it.Īs to where to get newer OSes, the place to start is with Snow Leopard (10.6). These hacks may require specific new hardware (e.g., new graphics card known to be supported by later OSes extra hard drive) and require careful attention to procedure. There are technical issues that prevent running 10.8 (Mountain Lion) or 10.9 (Mavericks) and there are also guides on the Internet from people who claim to have hacked their Mac Pros to get the later OSes to work on them. That being said as long as the present software does the job you will have to make your own decision.Īccording to the references I've seen, a MacPro1,1 machine can run anything up to Mac OS X 10.7.5 (Lion). ![]() Here is an image when I had an 8600 card in it.īut I would be looking to Intel Mac as you will be hobbled with the PowerPC structure and not a lot of software or compatible browsers. I did put in a GT-630 Nvidia card that used the native mac drives but since its a Peecee card no boot screen until log in. Now my Mac Pro which has a 32 BIT EFI (Hence Road APPLE) is running 10.9. Then I stumbled onto a forum about fellows making a Hackintosh out the 2006 MacPro until one clever fellow made a custom boot_EFI that could be used. I ended up getting last year a 27" iMac 1TB Fusion drive and JBOD to hold four SATA drives. When I found out it was not able to take 10.8 or 10.9 there was a lot of grumblings from owners of that vintage. Later I picked up a "road apple" (unknown to me at the time) a 2006/2007 Intel Mac Pro. Since you are familiar with G5 looking at it after taking out the plastic case the left hand side on the lower end I put in 3 SATA drive it had an L bracket and fan. ![]() I originally added a Seri_Tek SATA card and something like Sonnet but from a company in California. ![]() I too have an old G5 Tower and just gave it new life at our church.
