Nov 07, 2014 Like others, I have tried to install 10.10.4 on a Mac Pro 1,1 with no success. It ran fine with 10.10.3 and I mistakenly ran the update on from the app store as opposed to updating from my Macbook Pro with the MP in target disk mode – temporary loss of sanity. But now I have tried to do a clean install on the MP with no success. Then, choose the disk you want to install the El Capitan installer on. Click install and prompt your password. Boot the computer you want to install El Capitan on with 'alt' held and select your USB drive. Once booted, Click Continue, Agree and choose the partition you want to install on. May 21, 2019 Question: Q: Mac Pro 1,1 running El Capitan 10.11.5 So I had a 2007 Mac Pro (MacPro1,1) with OS X El Capitan 10.11.5 installed, using an NVidia Quadro FX 4800 video card because the original video card will not work with this OS X.
Upgrading to El Capitan
You can upgrade to El Capitan from Lion or directly from Snow Leopard. El Capitan can be downloaded from the Mac App Store for FREE.
Upgrading to El Capitan
To upgrade to El Capitan you must have Snow Leopard 10.6.8 or Lion installed. Download El Capitan from the App Store. Sign in using your Apple ID. El Capitan is free. The file is quite large, over 5 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
Macs that can be upgraded to OS X El Capitan
1. iMac (Mid 2007 or newer) - Model Identifier 7,1 or later
2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) - Model Identifier 5,1 or later
3. MacBook Pro (Mid/Late 2007 or newer) - Model Identifier 3,1 or later
4. MacBook Air (Late 2008 or newer) - Model Identifier 2,1 or later
5. Mac mini (Early 2009 or newer) - Model Identifier 3,1 or later
6. Mac Pro (Early 2008 or newer) - Model Identifier 3,1 or later
7. Xserve (Early 2009) - Model Identifier 3,1 or later
El Capitan Os X Download
To find the model identifier open System Profiler in the Utilities folder. It's displayed in the panel on the right.
Are my applications compatible?
See App Compatibility Table - RoaringApps
Note that upgrading to El Capitan is quite possible from Snow Leopard.l Please be sure your model is included in the above and that your computer meets the installation requirements.
If you need to reinstall El Capitan then try:
Reinstall El Capitan Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility and press the Continue button. After Disk Utility loads select the indented Macintosh HD entry from the the left side list. Click on the First Aid button in the toolbar. Wait until the operation completes, then quit Disk Utility and return to the main menu.
Reinstall OS X: Select Reinstall OS X and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless and more reliable.
If you cannot do the above, then you need to reinstall Snow Leopard and try again:
Reinstall OS X without erasing the drive
Installare El Capitan Mac Pro 1.1
1. Repair the Hard Drive and Permissions
Mac Pro 1 1 El Capitan Install
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say 'Verified' then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is 'Verified' then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
Mac Pro 1.1 El Capitan Installieren
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install Mac OS X 10.6.8 Update Combo v1.1.
