For developers, on the other hand, this secondary screen can be used as a drawing tablet using supported apps.
With the release of macOS Catalina 10.15, a lot of Mac users are enthusiastic to install the newest Mac operating system.

Some users experienced slow downloading of the update, while others got error messages when installing Catalina, including:
This guide will give you a detailed rundown of the most common macOS Catalina installation and update errors encountered by Mac users when upgrading or installing macOS Catalina, along with the instructions on how to deal with these hiccups.
Why macOS Catalina Won’t Install
Various problems can occur during the installation of macOS Catalina. If the installation won’t start, seems to freeze midway , or never seems to complete, then it means that there must be something wrong somewhere.
The first main reason why users can’t install macOS Catalina is compatibility problem. If your Mac doesn’t support macOS Catalina, you won’t be able to proceed with the installation. You need a fairly recent Mac to be able to run macOS Catalina. Here are the Mac models that support the newest macOS:
If your device is not on this list, then you’re sure to run into problems when installing Catalina.
Another thing you need to check before installation is your available storage space. You will need around 6.5 GB just to download the installer. Once you’ve downloaded it, the amount of space you will need during the installation depends on whether you’re doing a clean install or an upgrade.
A clean install will eat up around 20 GB of storage. On top of that, you have to make room for apps, user data, and user updates. An upgrade install, on the other hand, will only take up 6.5 GB of space for the installer, plus some installation files that the installer will copy to your startup drive.
If you’re tight on storage space, you should consider removing unneeded apps and files on your Mac. You can uninstall the apps one by one, and delete cache files and data using Outbyte MacRepair. Make sure you have at least 25 GB of free space to be able to install macOS Catalina successfully.
Aside from compatibility issues and insufficient storage, poor internet connection, incomplete or corrupted installation files, hard disk problems, and faulty software can also cause issues during the installation of macOS Catalina.

You might think that everything is over once you finish the installation process and your Mac restarts. But sometimes, errors can still happen even after the installation has been completed. Some users reported getting stuck with a black screen, while others encounter the spinning wheel during the restart following the update.
This error is usually caused by incompatible or corrupted kext files. Kext or Kernel Extension files are the drivers for macOS. To check whether kext files are causing the error, move all of them out of your Extensions folder before rebooting your Mac.

Get Setapp, a toolkit with fixes for all Mac problems
After summer comes macOS. This long-standing tradition started by Apple is the most exciting moment of the year — seeing your Macs improve and gain new bells and whistles. In 2019, we’re welcoming Catalina, the 10.15 version of macOS named after Catalina island in California. Apparently, it’s hot.
The operating system boasts a whole lot of new macOS features like Sidecar, iOS apps porting, and major Photos update. To try the features right away, you can install Catalina from the Software Update tab.
However, be prepared for some troubleshooting. The acquaintance with the new macOS doesn’t always go smooth — and with macOS 10.15 deeming support for lots of software, many things will not go smooth. We’ve collected the key macOS Catalina issues you may encounter, along with the ways to fix them.
macOS 10.15 Catalina problems and their fixes
Giving up Catalina is a decision you can choose to make. But before rolling back, ensure you use every bit of advice as to how you can fix the common problems. Sometimes, a quick fix can solve your concerns.
Get macOS problem fixes on Setapp
Beta or not, you can safely install any version of the new macOS. Setapp and its 150+ apps will solve every Mac concern you have.
Problems with macOS Catalina you can solve:
macOS 10.15 Catalina won’t install
This is the classic problem that arises with every macOS release: The installation won’t start or you face the “Catalina installation stuck” problem — when it freezes and you see no progress on the install. No matter how many times you start over, you keep getting an error trying to install Catalina.”
How to fix:
Say you’ve cleared up and backed up your disk. But your Mac still gets stuck at the installation and shows “not enough space” error, so you can’t get out of the cycle. In this case, there’s another fix you can try:
Some users also report they tried to reboot into Safe Mode and take the installation from there; the others used a newly created admin user — but most attempts have been unsuccessful.
We must agree that macOS 10.15 is one of the slowest systems in terms of installation. But if you use the hacks described above and have a little patience, you’ll be able to get to the “Catalina installed” point.
If you can’t login after upgrading to Catalina
There’s a known problem of failing to login after the installation. Unfortunately, the only way to fix it — at least for now — would be to roll back to Mojave:
One of the things Mac users are particularly excited about is the new Sidecar feature. It comes as a handy solution for those wanting to expand their workspaces. You can either mirror your Mac’s screen to iPad or use your iPad’s screen as an extension of a Mac.
If the only reason you’re here is because you want Sidecar, we have to warn you it might not work with your new macOS. Reddit is full of user reports about the feature unavailable on macOS Catalina. Most likely, this is the issue of compatibility.
How to fix:
Here are the ways to fix Sidecar problems:

Battery drain on macOS Catalina
Many of the previous macOS releases were known for battery life concerns — greedy apps, Safari and Chrome draining battery, or power-saving not working. There has been no major battery drain issues reported by the Catalina users so far.
How to fix:
Just to make sure you don’t encounter the problem as well, here are a few precautions:
Apps not working on macOS Catalina
In the attempt to speed up your Mac’s performance, Apple is killing 32-bit app architecture with the release of Catalina. This means you have to switch to 64-bit, for good. You might see the messages like this when trying to launch an app:
The chances are it’s one of the oldies.
How to fix:
CleanMyMac X can pretty much solve every app problem on macOS Catalina.
Uninstall all 32-bit apps in a click
No more digging through the settings. Download CleanMyMac X and batch uninstall every outdated app on Mac.
While app notarization takes time, you can expect many apps being unavailable after the release of Catalina. This doesn’t mean they are gone for good, though. Contact developers or follow official developer announcements to find out about compatibility plans.
OneDrive client problems on Catalina
Due to Catalina’s new security settings, Microsoft’s OneDrive may have a problem accessing your drive — even if you allow a full access. This is because macOS 10.15 comes with two disk volumes by default.
How to fix:
There are no surefire fixes just yet, but you can try to troubleshoot OneDrive by setting it up from the very beginning. This worked for some users, according to the Reddit discussion:
iCloud problems on macOS Catalina
The most common issue with iCloud is that users are unable to download their folders. You can try downloading iCloud files separately — but that’s going to be a pain if you have an extensive library.
How to fix:
The best fix would be using Forklift app for your file management. The app is Catalina-ready and allows connecting local drives, Dropbox, iCloud, and tons of other storage sites.
If you’re setting up iCloud, there might be another issue standing in your way: Not being able to agree to the Terms and Conditions. The window will just keep popping up on your screen. An easy way to fix this would be to access System Preferences > Internet Accounts and then click on the iCloud icon. You’ll see a static Terms and Conditions window — click Accept and you’re good to go.
Replacing iTunes on Catalina
The new macOS 10.15 brought along the end of iTunes and the birth of the new Music app. Basically, it looks the same — but with music-only content. There’s a huge difference for people who rely on syncing Apple Music with third-party apps. The new app doesn’t support XML file support, which makes playlist syncing impossible across many apps. So if you use Apple Music for DJing, you’ll definitely have a problem.
How to fix:
The only fix to suggest here would be to stay away from Catalina if you need your XML apps to work with iTunes.
Music library issuesNew Music app keeps freezing
There have been reports about the new music app freezing on Mac. Well, it’s the first splitting of iTunes, so it’s no wonder it doesn’t go smooth. In most cases, your Mac will keep showing the “library updating” status.
How to fix:
Memory usage problems with Apple Music app
Another problem you may come across is the Music app eating too much of your space. One user wrote the app used over 30GB of memory on his Mac.
How to fix:
Apparently, the problem is related to the memory management of Album Art. It is getting better, though. According to user reports, memory usage goes back to normal after restarting the app.
Mail search is broken
According to forum posts, your mailbox might get pretty messy after the upgrade — with no search functionality whatsoever. So if you try searching by keywords or recipient/sender name, the app will keep showing the numerical number of results. The reason could be the new Spotlight integration.
How to fix:
There have also been some early reports about emails missing from the Mail app — so you might want to wait for it to get fixed before upgrading, especially if you rely on Apple Mail.
Slowing down and overheating macOS Catalina problems
So here’s the thing: macOS Catalina should be faster than Mojave. 32-bit architecture was one of the things slowing an operating system down. It’s gone, and so are the issues with slow apps. Unfortunately, you can expect your Mac go slow and overheat anyway.
How to fix:

Dock disappearing on macOS Catalina
On the Apple forum, people mentioned Dock disappearing from their screen after upgrading to Catalina. The nature of this mistake is unknown — some users connect it to PRAM resetting, the others say they had the issue when trying to work across two screens.
How to fix:
Try Option + Command + D. If it doesn’t work for you, do the following:
Close the window and check whether it’s working now.
Internet not working after upgrading to Catalina
If you’re putting macOS 10.15 over your current system, you’re likely to encounter Internet connection problems.
How to fix:
The radical way would be to clean install macOS Catalina — it’s healthier for your Mac and will probably fix the issue. If you’re not ready to take a risk, try rebooting your Mac.
There has been a user report saying that Sophos caused the problem of network connection. So uninstalling it may be a fix as well.
Bluetooth not available on macOS Catalina
Well, that’s a problem. Definitely a huge one if you use AirPods. Deleting your Bluetooth.plist files might be the way to solve this.
How to fix:
Safari extensions not working
While Apple is trying to transition to iOS-compatible extensions, it gradually deems support for many web extensions formats. On Catalina, you’ll face the problem with .safariextz files not working.
How to fix:
Just like with 32-bit apps, there’s no way to fix the missing extensions. If you can’t find a good alternative, you can switch to Chrome or another browser.
Storage filling up too fast
If you notice unusual storage filling up progress, this might mean your Mac captured too many redundant files during the Catalina installation. In most cases, these are APFS files and Time Machine backups.
How to fix:
If you can use a good Time Machine alternative like Get Backup Pro throughout the upgrade, do it. Otherwise, you can remove Time Machine leftovers after installing Catalina with CleanMyMac X. In the Maintenance tab, select “Time Machine snapshots thinning,” and run a cleanup.

To remove snapshots manually, use the following Terminal commands:
1. To view the list of snapshots:
tmutil listlocalsnapshots / tmutil listlocalsnapshots /System/Volumes/Data
2. To delete snapshots:
deletelocalsnapshots
Here’s a quick review of all mentioned fixes, which you can take with you:
Is macOS Catalina stable?
The short answer is yes — if you use it right. So before you decide to downgrade back to Mojave, make sure you’ve done the following things right:
