If you have multiple Macs, you can also download and use the installinstallmacos.py file. When you run the tool, it will download the full installer for the Mac version you are installing. The tool will then save it on your desktop (or wherever you specify). If you have multiple Macs and want to use a single file to make the USB installer, this is the way to go. And if you want to use the full macOS installer to install the Mojave version, then you can do the same. (I’m not sure how to do this with the High Sierra installer.)
The installinstallmacos.py tool allows you to download the macOS Mojave installer for any Mac model, without needing the App Store. We’ll show you how to use this tool and how to make a bootable macOS USB for your Mac.
Step 1: Download and install installinstallmacos.py to your Mac. You can find the installinstallmacos.py tool in the download section of the GitHub site. Download this tool on your Mac and install it.
A macOS USB installer is used to make a bootable macOS installer from your Mac OS. The procedure is pretty easy, but you should take some precautions before proceeding. Read this post carefully to make sure you don’t affect the integrity of your Mac OS.
I have been using macOS Catalina for a couple of weeks now. I can confirm that the new features are excellent and you should be patient and wait a little bit before you make a judgment call about how your device is performing. There is no way of knowing how an upgrade will work until you upgrade. I wish I could give you a definite answer to the how much better it is now. That is a matter of personal opinion and experience. All I can say is that it is worth the upgrade. The UI is an improvement over Mojave and I am sure you will like the new features. There are some issues to be aware of but I have been able to work around them. My big concern is the performance. As a software engineer, I have high expectations and I am shocked at how slow the system feels. It is not a case of the new Catalina is slow but it is how slow. In fact, it is so slow that I have been discussing the issue with Apple Support. They are aware of the issue and I am told to see them next week to discuss the issue and hopefully get some resolution.
If you have an older Mac, you may not be able to upgrade directly from 10.15 to 10.15.1. Depending on your Mac, the upgrade process may work but could be temperamental. We still recommend that you follow the general instructions above to download the installer. Once downloaded, you can launch the installer application and follow the prompts that appear.
