I find the easiest way to find these directories is to launch terminal and enter ‘open -a finder /volumes/volumename/usr/standalone/i386’ where ‘volumename’ is the name of the disk on which you’ve just installed Mavericks and ‘open -a finder /volumes/volumename/system/library/coreservices’. When the installation had finished and before rebooting I used the iMac to overwrite the boot.efi in the following two locations on the new drive with Tiamo’s modified version. I ran the Mavericks installation via the iMac and after initialising the new SSD installed the OS.
I removed all other drives and inserted a new Crucial M500 SSD, booted the machine into TDM and attached it via Firewire to my Mavericks friendly 2010 iMac. I decided therefore to attempt the same trick with the Mac Pro. This was achieved by launching the machines in Target Disk Mode (TDM), attaching them via Firewire to my Mac Mini G4 and running the installation from there. Some months ago I managed to install a later, unsupported version of OS X onto both my iMac G4 and Cube. I actually took an alternative route to get Mavericks on to my 1,1 but still required Tiamo’s rewritten boot.efi. Recently it has become possible, thanks to the excellent work of Tiamo over on the Mac Rumours forum to install Mavericks on the 1,1 without the need for Legacy Boot and additional drives. The most common I’ve seen being running the Chameleon boot loader from a separate drive using legacy boot, Jabbawok created a guide. A number of hacks have been in the wild for some time and allow you to get around this limitation. My Pro is the very first of the Intel machines introduced and is crippled by a 32bit EFI although the Xeon CPUs are of course 64 bit. Later versions require a 64bit EFI to boot. The last version of OS X officially supported for the Mac Pro 1,1 is 10.7.5 Lion. However I have a number of other Macs and have become accustomed to running OS X Mavericks and would really like to be able to run it on the 1,1. From a performance perspective I’m still not suffering any great hardship with my Mac Pro 1,1. After factoring in the costs of adding Thunderbolt equipped external storage it is also impossible to justify the cost. It therefore seems likely that I’m not alone in still running one of these venerable machines.Īfter what seems like an eternity waiting for the new Mac Pro to arrive, as superb as it is it doesn’t suit my needs.
The upgrades were a success and the posts I made such as upgrading the Xeon CPUs remain some of this blog’s most popular. Back in 2012 I made a numer of upgrades to my Mac Pro to try to extend its useful life.
