Catalina, the latest version of macOS, offers beefed-up security, solid performance, the ability to use an iPad as a second screen, and many smaller enhancements. It also ends 32-bit app support. MacOS Catalina 10.15 is the latest operating system that runs on Apple Mac laptops and desktops. However, it is still in beta test and only available for part of Mac computers with high profile or enrolled in Apple Beta Program. Is there any way to upgrade the macOS to Catalina manually or install Catalina on Mac from scratch? The answer is Yes. As updates that change the macOS version number become available, this article is updated to show the latest version of that macOS. If your Mac is using an earlier version of any Mac operating system, you should install the latest Apple software updates, which can include important security updates and updates for the apps that are installed.

People accuse electronics manufacturers of built-in obsolescence: that hardware is designed to stop working or not be useful after a relatively short period of time. Apple has generally avoided that with Macs, letting many of its models receive OS X and macOS updates for five to seven years after the computer version’s initial release. And some people keep older systems running indefinitely, as I noted in a recent column that started with people’s love of 10.6.8 Snow Leopard, now over a decade old.

But Apple doesn’t provide a guide as such as to the “terminal” version of its operating system you can install on any given computer. That is, how do you find the last version your computer is compatible with? Mac os catalina on usb.

You can track it down, but you have to work in reverse. Apple has a page for each release that in older versions of the OS describes the features required in Macs to handle it, and in newer versions lists the oldest models supported or spell out every model. There may be additional requirements, such as minimum RAM installed, and one always needs a certain amount of free disk space, often specified.

For example, for Mac OS X 10.7 Lion, released in mid-2011, Apple notes that an “Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor” is required, but not which models; 2GB of RAM is also needed. Fortunately, third-party sites can provide the reverse lookup that helps narrow this down. EveryMac.com, which dates back nearly 25 years, has pages that list every Mac model by processor. Click on Core 2 Duo, and you can find that the late 2006 17-inch iMac is among the earliest that can be upgraded to Lion.

Finding some of these Mac updates is tricky, but our colleagues at Macworld UK have a rundown of how to find downloads for OS X and macOS releases over the last decade. If you can only find an installer that upgrades from an existing OS X or macOS release, you may have to install a later version, often 10.6.8, before using the upgrader.

Here are the links to find system requirements for Lion and later:
