How Long Does it Take to Install macOS Catalina Beta?

If you decide to install the macOS Catalina beta on your Mac, it will take some time to download and install. You need to make sure you have enough time to complete the download and then install it on your Mac. You will need WiFi and try to stay connected to power while installing the update.

We’ll take a look at how long the macOS 10.15 beta installation will take and help you figure out if you have enough time. There’s a chance your download will take much longer the first day, but if you have a good internet connection that shouldn’t be too bad.

Apple is offering a developer macOS 10.15 beta today, but you can join without a developer using our guide. Before installing, there are a few things you need to do to get you and your Mac ready.

With the first macOS 10.15 beta release, users ask us, “How long will it take for macOS Catalina beta to complete?” We hear you ask. We will try to help you estimate using various factors.

If you are already backed up and have no issues, you should plan to set aside at least an hour for the process. Since this is a large download and connection speeds vary from user to user, the outlier will be the download time. Here’s a breakdown of how long the macOS Catalina beta has been completed;

This does not include the time it took to download and install the macOS Developer Beta Utility, which should add a few minutes to the process. If you run into problems with macOS 10.15 beta, you’ll need to make sure you have a backup, as this is the easiest way to upgrade to macOS Mojave. If you’re not ready, that’s a good reason not to install macOS 10.15 beta yet.

Prepare for macOS 10.15 Beta

Don’t approach macOS 10.15 beta as you would a traditional macOS update. This is a pre-release update that requires a bit more planning and a bit more prep work.

Before you install macOS 10.15 beta, take a look at what you need to do. It will save some time, but will make your installation and any possible downgrades much easier.

macOS Catalina Beta Download Time

On the first day of beta, the macOS Catalina beta download will likely take longer than if you had to wait a few days. This is because many other users are trying to do the same. The other factor is your internet connection speed.

In our experience, you can expect to spend at least 20 minutes downloading the update, which should be around 5GB in size, and for some home users it can take up to two hours.

macOS Catalina Beta Install Time

The macOS 10.15 beta installation can be completed in less than an hour in most cases.

The macOS Catalina Beta install time is between 30 and 60 minutes. This includes download time and installation time. If you choose to install on an external hard drive, you may need to spend a little more time installing it than on an internal SSD or Fusion drive, but that shouldn’t change things much.

Most of the time you won’t be able to use your Mac while installing macOS 10.15 beta. During this part of the process, your Mac will appear on a black screen while installing the beta, so plan accordingly.
