Been running Catalina since the beginning on a 2012 Mini and a 2018 MBP.

I have never experienced any problems with Catalina on either Mac.


Lots of people install system modifications like cleaning apps, anti-virus apps, optimization tools, maintenance tools, or just plain garbage. All of those things cause issues with the OS, especially after an upgrade because the garbage ware isn't compatible.

They think it is bugs in the OS, but it is really just poorly designed garbage they chose to install.


There is a wake from sleep problem that mostly affects the new 16" MacBook Pros.


There are also things that are different that has apparently caused the sky to start falling for quite a few people. Mail doesn't really have the "Classic Layout" anymore. There is a column implementation, but the columns are not configurable nor sortable. I had no idea so many people's lives depended on that layout.


iTunes was finally split into component parts and the syncing features to iOS devices is now in the Finder. There have been reports of problems viewing the contents of the iOS device, so that could be a problem for you.

People complained about iTunes forever, now thy get to complain about three or four different apps.


Apple is slowly working to eliminate third-party kernel extensions. Catalina goes a step further down that path making it somewhat difficult to install them and get them working, but they do still work.


Catalina locks down the OS part of the system by mounting it read only. If you liked to store your files outside of your home folder, Catalina pretty much won't let you. Anything you have stored in protected locations will be moved to a Relocated Items folder.


Catalina drops all Apple support for Java. You have to install Oracle's Java implementations if you rely on Java for anything. However, there are plenty of ignorant developers who hard coded their apps to only use Apple's Java 1.6 implementation. Since that doesn't exist and they failed to properly write their code, some apps that use Java tools won't work in Catalina.


File Sharing has also changed, but that change is just an extension of the switch to APFS. If you were running an OS prior to Mojave, then it is different. Any APFS drives can only be shared out via SMB. AFP will not work for them.


Any 32-bit apps you have will not run at all under Catalina. You can find them in the System Information under Software > Applications, 64-bit Intel column, but St. Claire Software created a nice app to do the same, Go64.

If you depend on any 32-bit apps, you need to find an alternative or see if there is an update. Some may be a free update, but most large software suites require you to purchase a new version, or use an alternative.

I will report on bugs experienced on two Macs. Given how late we are in the release, it is certainly safe to install, assuming you have confirmed your Mac is on the compatibility list.


-Macbook 2015

*unable to access any tags, they come up blank: did not get this on my Mac mini, so presuming a fresh install fixes

*unable to access iPhone over wifi, it does not display: did not get this on my Mac mini, so presuming a fresh install fixes


-Mac mini 2020

*left airpod, no sound : occurred because the audio balance defaults to right ear, this was fixed manually

*menu bar icons sometimes invisible, at random intervals(the menu bar app is there, it is just invisible, and there when I click on it)

*very slow resume from sleep, up to 50 seconds

I've been running it on a 2012 Mini and a 2018 Mini.

2012 Mini is unusable. 2018 Mini has issues with Logitech Trackball. Many others have reported this also. Supposedly Logitech is trying to work it out with Apple, but I'll be surprised if it gets fixed. I'd blame Logitech, not Apple for this issue.

Likely needs an SSD, either alone or as a Fusion drive.

I had a Laser MX mouse about a decade ago. Logitech could not write a kernel extension that would survive an update much less an upgrade. I haven't used any Logitech products since. I don't know why they must hack the system to make their input devices work. My guess is they won't make any products for the next macOS when Apple prevents the current kernel extensions.
