Chapter in this post:
If you want to equip your old Apple Mac, iMac or MacBook with its original operating system or if you want to get an old collector's item back up and running after repairs, you need an appropriate installer. The installation file for the Mac OS X system or the macOS version is of course available on the Internet. From a recent dialogue with a reader, however, I know that some users end up looking for an installer on dubious sites or fall for fraudsters on eBay. That's why I've put together a reputable download list for installers for old macOS and Mac OS X versions in this post.
A reader recently asked me about a macOS High Sierra installer. I still had the El Capitan and the Sierra Installer on the disk, but of all things High Sierra no longer. He then made an attempt to download it from a shady website, which turned out to be a virus thrower. A second attempt was to order a DVD on eBay, but here was only a self-burned DVD that was not even bootable for nine euros. Now I have told him that I am him with DiskMaker X make a bootable medium and one of it ISO generate. I'll send it to him and he can then burn a bootable DVD for his Mac on his PC.
If you are also looking for old macOS versions, you will find a list of downloads here. It takes you directly to the Apple Mac App Store, the Apple online shop or the developer area. Because in addition to more recent macOS versions, which are available for free in the App Store, others are only available at face value in the store and still others only as beta builds for developers. In return, you get the security that no viruses or Trojans, ransomware or other malware are included in the download.
Here is the Mac OS X and macOS Installer download list:
(As of March 14, 2019; iTunes links can independently open the App Store on Apple Mac, iMac and MacBook)
You are welcome to send me your questions about and problems with your Apple products. I will then try to help you solve the problem. If the topic - like the installers for old Mac OS X and macOS versions - could also affect other readers, then I'll make a public contribution in addition to personal advice. So everyone benefits from your request. A win-win situation that also brings more serious and tested Apple knowledge to the Internet;)
