Common macOS Catalina Installation Problems
There are many problems you may come across while installing macOS Catalina. These include the following:
1. Compatibility Issues
Not all Macs support Catalina. Only Macs released in 2012 or later are compatible with macOS Catalina. Here is a complete list of Macs that support the latest macOS version:
- 12” MacBook (2015 or later)
- MacBook Air (2012 or later)
- MacBook Pro (2012 or later)
- Mac Mini (2012 or later)
- iMac (2012 or later)
- iMac Pro (2017)
- Mac Pro (2013 or later)
2. Disk Space Problems
To be able to download the macOS Catalina installer, you need to have 6.5 GB of free storage space. However, you have to be aware that the amount of disk space required may vary depending on the type of installation that you are doing: a clean install or an upgrade.
Generally, a macOS Catalina clean install requires 20 GB of storage space. Then again, you will need more to allocate space for other apps and future updates. An upgrade, on the other hand, requires 6.5 GB of free space plus a few more gigabytes for the files the installer will have to copy to the startup disk. For an upgrade, it’s hard to give a rough estimate about the total free space needed as many factors need to be taken into account. But to be safe, make sure you have at least 25 GB of free storage space available.
If you are tight on space and can’t proceed with the installation, you might need to install a reliable tool to get rid of unnecessary files on your Mac. One that we recommend is Outbyte macAries. In just a few clicks, this tool can identify any space hoggers on your system.

3. macOS Catalina Could Not Be Installed

4. Mac Is Frozen While Installing Catalina
If your Mac is stuck while installing Catalina, there could be many reasons behind it. While some are associated with the software, others are hardware-related. But regardless of what’s causing this problem, we can guarantee you that there is a fix. You’ll know more about it below.
What to Do When Catalina Installation Is Stuck?
Is your Mac stuck in the “Setting up Your Mac” part during Catalina installation? We suggest that you try the fixes below:
1. Restart Your Mac.
Oftentimes, your Mac gets stuck while installing Catalina because there are system processes that simply need to be restarted. All you need to do is simply restart your Mac.
You have three ways to restart your Mac. The first one requires you to press the Power button and select Restart from the list of options. The second one is about pressing the Apple key and hitting Restart. Lastly, to restart your Mac, you can press the CTRL + CMD + Eject combo.
2. Reset the NVRAM and SMC.
The NVRAM and SMC store information required when your Mac starts up. Once any of them becomes corrupted, it can cause your machine to freeze. Though resetting the NVRAM and SMC doesn’t always guarantee fixing the problem, it’s still worth trying as it has worked for some.
Here’s how to reset the NVRAM and SMC of a Mac:
- Turn off your Mac.
- Press and hold the Power button for at least 10 seconds.
- Release it and wait for a few seconds more before restarting your computer.
- If the issue persists, switch off your Mac again.
- Remove the power cord.
- Wait for 15 seconds before reconnecting the power cord.
- Turn on your Mac.
3. Check the Log Screen.
When you’re stuck in the “Setting Up Your Mac” part of the Catalina installation, you might want to check the Log screen. There might be missing files that need to be installed. If it shows nothing is happening, then proceed to the next possible fix.
4. Install the Combo Update Instead.
If you are having problems with installing Catalina, you can visit Apple’s website and download the Combo update. This includes all the important files required to update to the latest macOS. Downloading and installing this Combo update will replace all outdated system files.
5. Seek Help from Experts.
When all else fails, your last resort is to seek help from the experts. Take your Mac to the nearest Apple Center and have it checked by an Apple Genius. If your Mac is still under warranty, then great because this service might not cost you a lot. Otherwise, prepare to spend a few hundred bucks.
If visiting an Apple Center is not a good idea in your case, then you can reach out to Apple’s online support team. Head over to their website, answer a few questions, and you might just be given a quick fix.
Catalina installation issues are inevitable, especially considering that the macOS version is new. Lots of features still need to be checked and improved, and errors may not have been seen by the QA teams. But even if installation issues are common, they should not stop you from trying the features that the new OS has to offer. After all, the developers of the OS are constantly working to improve Catalina and are regularly releasing patches with fixes to commonly reported bugs and errors. As long as you take note of the important details and try out different solutions being shared on forums and blogs, then you should be able to enjoy Catalina the way other Mac users do.

Can you install macOS Catalina on an external SSD connected to your Mac? Yes, it's definitely possible. However, since Apple initiated a relatively new partition scheme (APFS) with macOS High Sierra, the process is slightly different than with older versions of macOS. This article shows you how to set up a new SSD with macOS Catalina that you can boot from.
Why Installing macOS Catalina on External SSD?
macOS can be installed on an external storage device by default, such as HDD, SSD or USB flash drive. And this priciple also applies to macOS Catalina. For permance consideration, external SSD is much better becaus of faster reading and writing speed. The good news is that external SSD is much cheaper than before and the price gap is much smaller.
Now, the big question is why you don't want to install macOS Catalina on your main hard drive. After all, if you're upgrading to macOS Catalina, you want your Mac to boot to it all the time, don't you? Not necessarily. There are several reasons why you might not want to disturb your current installation, whether it's Catalina or an older version of macOS. Here are some possible reasons.
● You might want to try macOS Catalina without having to uninstall and roll back to Mojave or High Sierra if you change your mind. Uninstalling and rolling back to an older version of macOS is time-consuming and a tedious process that is prone to errors, so you may not want the hassles that come with it.
● Your Mac (Mostly Mac Mini or iMac) is built upon on a HDD and it runs slowly. You are looking for a way to boost the performance without untouching the internal drive.
● Since there are bound to be bugs in early versions of any new OS, you might want to avoid the hassle of having it as your default OS. This way, you can update it as new versions are released, then install it as your main OS when you're happy with the stability of the software.
● You may want to have the SSD run macOS Catalina on more than one machine. Since your SSD is essentially an external drive that is portable, you may want to switch it between one Mac and the other. Instead of installing Catalina on both, you have the flexibility of simply connecting the SSD to one of the Macs when you want to boot from it.
● It's also possible that you want to run a different set of apps and, therefore, need more memory. If you use a larger-capacity SSD, this will allow you to load a ton of heavy apps like Photoshop and so on, which might not be possible with your current hard drive because it is already full of data.
How to Pick up the Right External SSD for Catalina
Mac computers are made different from PCs. It has its own hardware port and unique standards. So not all external SSDs are suitable for Macs. To maximize the performance of SSD, it should be USB 3.0 compatible, if you have enough budget, ThunderBolt port is more welcome as it has much faster reading and writing speed. Besides, the volume should be 128 GB or larger. Below is a list of best external SSDs for Mac:
