The latest offering of Apple’s desktop operating system is the macOS Catalina. It was announced at WWDC 2019 on June 3, 2019, and became publicly available on Oct 7, 2019. macOS Catalina introduced a plethora of features that people were expecting from apple as debated on the internet much before the official release.
Most Mac users get their feet wet by updating as soon its available. But there are also various users who wait for any issues to surface before updating their macs. It might be a smart thoughtful manoeuvre from their side, but they could still face issues with the installation or after it.
Download and Installation Issues in macOS Catalina
Before diving into the issues and their fixes, check to ensure the macOS Catalina is compatible with your Apple hardware. Here’s a list of compatible machines.
- iMac (2012 or later)
- iMac Pro (2017)
- Mac Pro (2013 or later)
- MacBook 12-inch (2015 or later)
- MacBook Air (2012 or later)
- MacBook Pro (2012 or later)
People with compatible systems still show up with problems afflicted with the macOS download and installation even though it’s a simple process done in the Appstore.
If you are getting the prompt: “The network connection was lost”, you don’t need to stress about it. This error is usually the cause of a faulty server or an unstable network connection. It’s advised to update your machine over a wired ethernet connection than the less reliable Wifi connection.
If you are getting the prompt: “Installation of macOS cannot continue” it’s a not a stressful matter either. This error commonly prompts when you don’t have the required space for the update. The download file is around 6 Gb and the installation requires about 20 GB on your drive. To check your storage click the Apple icon on the top left and click About This Mac > Storage(tab).
If you have insufficient space then you need to remove unnecessary files from your computer or, transfer your data to an external drive to alleviate the process.
Corrupted/interrupted update? Make a search query: Install macOS 10.15 in the Finder app and delete the file. Then try downloading the file again.”
“Gateway timed out” or “bad gateway” prompt? Start your mac in safe mode and try downloading and installing the update. Logging out and Logging in their iCloud account has worked for many as well.
Update file downloaded, but didn’t start? Search for Install macOS 10.15 in your Finder app and open it to begin the update.
Sidecar Issues in macOS Catalina
Sidecar is a dominant addition to the macOS Catalina. It transforms iPad into a secondary display to your Mac, helpful for Artists and multitaskers to accomplish more with high precision. Check to ensure your iPad Is eligible to work as a Sidecar.
- iPad 6
- iPad 7
- iPad Air 3
- iPad Mini 5
- iPad Pro (All Versions)
Check your iPad is running the latest iPad OS.
Secondly, check your Mac or Macbook if it’s compatible with Sidecar.
- iMac 27-inch (Late 2015 or newer)
- Mac Mini (2018)
- Mac Pro (2019)
- MacBook (Early 2016 or newer)
- MacBook Air (2018)
- MacBook Pro (2016 or newer)
You can find the Sidecar settings in your System Preferences located in your Mac dock and need to turn-on Bluetooth, Wi-fi and Handoff both on your Mac and iPad. Note that both your iPad and Mac are connected to the same network, as sidecar won’t work otherwise.
In case your iPad isn’t in the compatibility list, don’t worry, you can try third-party apps like Deut Display which has been providing Sidecar functionalities for a long time now. There is also a Reddit guide to using Sidecar on older mac machines that you can follow.
Bluetooth Issues in macOS Catalina
People are addressing issues with their Bluetooth accessories not working in Catalina. First of all, open the settings and navigate to Bluetooth preferences. Point out the devices troubling you, delete them and repair.
This should resolve your Bluetooth problems, but in case you are still facing them, open your Finder app and click on Go in the menu. Click on Go to Folder and enter “/Library/Preferences.”. Here, delete the file named “com.apple.Bluetooth.plist.” You may save the file before deleting as a backup to be on the safe side. Now restart your Mac and the Bluetooth pairing process will initiate again.
Mouse Issues in macOS Catalina
Some Catalina users also faced issues with Mouse not working. Just like before, head over to the menu and click Go > Go to Folder and type in “/Library/Preferences.”. Now here you’ll need to delete two files namely, “com.apple.AppleMultitouchMouse.plist” and “com.apple.driver.AppleBluetoothMultitouch.mouse.plist”.
After this, restart your Mac and hopefully, your mouse will be working again.
Login Issues in macOS Catalina
Some people encountered problems logging into their system after updating to macOS Catalina.
Restart your macOS Catalina, press and hold Command + S as it’s booting up, a command prompt will show up. In the prompt type in: /sbin/mount -uw / and press Enter. Then, type in rm /var/db/.applesetupdone
Doing this will remove any bad file that might be interfering the login process, and reinstate it to its freshly installed state.
Now you can enter your mac flawlessly.
No More 32-bit apps on in macOS Catalina
Yes. Starting from macOS Catalina, you won’t be able to use 32-bit apps anymore. So, if you’re using any 32-bit app like 1password 2.12.2, VMWare Fusion 3.1.4 etc you will be needing to update to its 64-bit variant or find an alternative, which, is quite possible with the availability of a large number of apps in the Appstore.
If you haven’t upgraded to macOS Catalina yet, you can check if the app you are using is 64-bit or not, and whether it would work on macOS Catalina. Go to About This Mac > System Report > Software > Applications. In the list, you’ll see a column called 64-bit (Intel) it if it shows “No” next to your app, then that version of the app won’t work in Catalina.
File Access (not actually an issue) in macOS Catalina
The revamped security system in macOS Catalina will now ask for your permission when your app wants access to certain files and folders on your Mac. Such behaviour has long been seen in the iPhone, and now it’s on Mac. I wonder why Apple took so long to add it to the Macs. Anyways, if you happen to unexpectedly deny access and want to change permission. You can easily do it.
Click the System Preferences in your Mac dock and click Security & Privacy, then on the next window click the Privacy tab. First on the left pane, click the component, for example, Files and folders, Camera, Microphone and then on the right pane select and check the app to grant them the required permission to access your component.
Once you’re done with granting or repealing accessing rights. Restart the app to see the changes.
Slow Performance Issues in macOS Catalina
After a new upgrade to the OS, lethargic behaviour is often seen by many users due to OS updating files and upgrading libraries in the background. After some days the OS would start working normally but, in case you don’t notice any drop in slothfulness, try restarting your Mac, and if it still persists then you might need to do a fresh installation of Catalina instead of updating it, to check if the performance issue ensues.
Although it’s not considered to be a game-changer for your mac’s issues according to experts online, you can give it a try.
If you don’t have trouble using the terminal commands then follow the guide to make a bootable installer, by Apple. However, you can also visit the Apple Genius Bar to assist you in the fresh installation of macOS.
To tell you the truth, I had NONE of these issues updating to Catalina on my 13-inch early 2015 MacBook pro. In fact, none at all since its release. It came to me as a surprise that people are facing issues with it. Anyways, I hope these fixes resolve your macOS Catalina issues.
