The OS that Apple changed the name from Mac OS X to macOS Available to end users on September 20, 2016, macOS 10.12 Sierra heralded the introduction of Siri on Mac, bringing Apple's digital. Officially, the operating system that was available on that Mac at the time that you bought it is the oldest version of macOS that can run on that Mac. It's likely that an older OS won't include. I tested everything the last maybe even more then 7 days. This knowhow i would like to share, just in case somebody else has the same problems. The Version from Robert Harder is 2.1-7. With this Version you have to build a var/lock directory with the right permissions. The problem is that from Mac OS 10.5 this directory isn’t installed.

Before installing any upgrade, it’s a good idea to back up your Mac. Time Machine makes it simple, and other backup methods are also available. Learn how to back up your Mac.
It takes time to download and install macOS, so make sure that you have a reliable Internet connection. If you're using a Mac notebook computer, plug it into AC power.
If you're using macOS Mojave or later, get macOS Big Sur via Software Update: Choose Apple menu > System Preferences, then click Software Update.
Or use this link to open the macOS Big Sur page on the App Store: Get macOS Big Sur. Then click the Get button or iCloud download icon.
After downloading, the installer opens automatically.
Click Continue and follow the onscreen instructions. You might find it easiest to begin installation in the evening so that it can complete overnight, if needed.
If the installer asks for permission to install a helper tool, enter the administrator name and password that you use to log in to your Mac, then click Add Helper.
Please allow installation to complete without putting your Mac to sleep or closing its lid. Your Mac might restart, show a progress bar, or show a blank screen several times as it installs both macOS and related updates to your Mac firmware.

If you're using OS X El Capitan v10.11.5 or later and your App Store preferences or Software Update preferences are set to download new updates when available, macOS Big Sur will download conveniently in the background, making it even easier to upgrade. A notification will inform you when macOS Big Sur is ready to be installed. Click Install to get started, or dismiss the notification to install later. When you're ready to install, just open the file named Install macOS Big Sur from your Applications folder.
Sure! Thing is-Apple doesn't put out a list of which video cards out there on the market do and don't work for sure.you could try looking around on the forums to see if others have had success. That being said the process is easy-shut down the Mac Pro and take off the side panel.lever for doing so is on the back of the Mac. Touch the frame. Look by the fan.there should be a button.press it and you're able to slide something out of the way.that one stumped me the most. The video card goes in slot 1. Wiggle it in.oh,and you're going to want to undo the bar with the 2 screws on it first( screws can't come out) then wiggle the card in. It sorta goes in at an angle. You're also gonna want to make sure the power cables to the card are hooked up as well.the connectors for that should be on the board and they are 6 pin( molex??) and you should have gotten the cables with the card. So after you have put the card's connector in at a slight angle,making sure it is seated all the way in,and the power cables are connected,and the bar on the side? is back in place, press the button and slide the bar underneath back, and put the side panel back on.touch the frame before doing so.and power up your Mac after plugging in the monitor to one of the video outputs. If you see a picture on the screen,congrats,you are done,if not, certain types of that card may work better than others,or it may need to be flashed to work with Mac. No,I don't know how to do it or who does it,apart from macvidcards.com
