Mac can t download anything. If you’re excited at the launch of macOS Catalina and want to try out all the new features for yourself, you can download the public beta from July and give it a go. However, as it’s beta software, it comes with a health warning and you should take precautions when testing it. One way you can do that is to create a dual boot system so you can still boot into Mojave, or whatever macOS you’re currently running, when you need to. Here’s how to dual boot macOS Mojave and macOS Catalina.

For Newer MacBook After 2018. The MacBook Pro, MacBook Air, and Mac Mini models. This means that if your Mac is older than 2012 it won't officially be able to run Catalina or Mojave. In the case of Catalina that includes all the old-style Mac Pro models, pre-'trash can'.
Clean up your drive beforehandShould I Upgrade To Macos Catalina
Once installed, macOS Catalina will have access to all your files and folders, so back up your Mac just in case it damages them. You can use Time Machine or any other backup tool. Just make sure you have a backup of your entire Mac before you download macOS Catalina. You should also consider turning on FileVault. It will slow your Mac down, but will force Catalina to ask for permission before it access encrypted files and folders.
The other thing you should do is clear out the junk on your Mac. We’re going to install Catalina on your main startup disk (yes, you don’t need an external disk!), so the more space you have available, the better. It’s not often that I recommend specific applications, but for this purpose, I’m a big fan of CleanMyMac X. It makes it really easy to identify what’s taking up all your disk space, thanks to its System Junk tool. And it makes it easy to remove junk files, too. You can either let it scan your whole Mac, or focus on specifics like iTunes, Photos cache files, Launch agents, or large and old files you no longer need to access regularly. You can download it here, so I recommend giving it a try, you might find that it frees up tens of gigabytes of space. What you’ll need for macOS Catalina

3. An APFS-formatted startup disk. If your Mac is running High Sierra or Mojave, its startup disk is probably formatted as APFS. The exception is hard disks or Fusion drives running High Sierra. You can check the format of your startup drive by clicking Launchpad > Disk Utility.
If your start-up disk is not formatted as APFS, your best option is to install Catalina on external drive. In this case, instead of using Disk Utility to create another volume on your startup disk as shown below, you should grab a USB stick or external hard drive with at least 16GB capacity and use Disk Utility to erase it and reformat it. Then, when you install Catalina, below, choose it, rather than the second volume, as the location for the install.

Depending on when you read this, macOS Catalina will either be in developer beta, public beta, or full release. If it’s still in developer beta, you’ll need to wait until the full public beta is available in July, unless you’re a registered Apple developer.

Before you download macOS Catalina, you’ll need to create a volume on which it can be installed. If you’re running Mojave, your startup disk will be formatted as APFS.

My apps don’t work on macOS Catalina
First thing people notice after they run a new OS is some of their apps stopped working. Annoying as it is, not all developers have yet optimized their software for Catalina. A large portion of your applications may still be 32-bit, which macOS Catalina won’t support.
There’s a quick 5 second way to check which of your apps are 32-bit.

You should never use a beta version of an OS for day to day work, so it avoids that problem too. https://potentergo332.weebly.com/blog/electrax-vst-free-download.
