If a macOS installer can't be used on your Mac, the installer will let you know. For example, it might say that your Mac doesn't have enough free storage space for the installation, or that the installer is too old to be opened on this version of macOS.

If you want to check compatibility before downloading the installer, learn about the minimum requirements for macOS Catalina, Mojave, High Sierra, Sierra, El Capitan, or Yosemite. You can also check compatible operating systems on the product-ID page for MacBook Pro, MacBook Air, MacBook, iMac, Mac mini, or Mac Pro.

Make a backup
Before installing, 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.

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.

What Macs do you Own? We posted a poll to see what computer has the most votes. While a G5 may be a decent day-to-day computer, the G3's are vintage and still can do some amazing things such as being the jukebox at a party or a kitchen computer, or go to extreme lengths and use them as your daily machine! The list is a bit long, so why not fill the text here! Quite a few people still have Power Mac G5s kicking around, and quite a few people have iMac G3s around as well. That's our guess of what still has the most ground in the PowerPC World. The PPC Archive team ourselves has a variety of machines, ranging from iMac G3s, Blue and Whites, iBooks, PowerBooks, and G5 systems! Some, still have Xserve computers that they use! Crazy thought, a rack server as a main PPC mac, but hey it's still a Mac! All the computers on the list to the right are cool, and each one pushed Apple further and further into the modern world. No other PC was designed like the early 2000 Apple computers. Today, there is a boatload of all in one computers like the current iMac. All the laptops out there are out to beat the 'ultrabook' MacBook Air. Companies such as Dell and HP attempt to steal the design that makes the MacBook Pro what it is. People look at the Mac mini as a excellent home computer or to make a super cool TV Media Center Setup, or even go to the extreme and use one as a server for 30+ iMacs! All of these design terms were the same during the PowerPC era of time! At the end of the day, Apple is still the one to beat! |
