Catilalina (null) ????

Does anybody know how this same update is displayed In System Preferences > Software Update on a Mac that is already running Catalina?

Can anybody that is concerned about this explain exactly why they are concerned?

It is apparently a glitch in the update server because it cannot tell the difference between the 10.15.4 version of Catalina and the 10.15.4 w/supplemental update version of Catalina. Both will have the same version number, 10.15.4. However was supposed to give the updated version a name failed to do so, hence the "(null)"

People with Catalina installed (but without the 10.15.4 Supplemental Update) will see an available update for the 10.15.4 Supplemental Update. They will not see the Catalina Upgrade like people who do not have Catalina installed.

I am not getting the AVAILABLE update that could be available if I decided to go to Catalina.. that is always there UNDER about my Mac ... then software update 10.15.4...Its there whether I want to update now or not and wait...But suddenly you get a null.... I am not updating YET and the 10.15.4 should still be there... It went from the original Catalina and the various updates if one does not choose to update it still remained there..THATS IS THE ISSUE!! I am not looking g to get rid of Mojave just yet but the Catalina update 10.15.4 was there ..Now it null... Something is wrong somewhere. I HAVE NOT UPGRADED TO CATALINA YET

…

But suddenly you get a null....

That is the Upgrade. The Upgrade will always be the most current version. The most current version is not named correctly (or likely not at all) so you see (null). Stop freaking out. It means nothing.

As I believe that I have been the only one who has asked this question in this thread.

So someone who has been on Catalina for several versions could have updated to 10.15.4 when it first became available, only to see soon thereafter that 10.15.4 Supplemental Update was available, whereas somebody who had already updated to 10.15.4 would see the same supplemental update on Catalina that is displaying as (null) on Mojave?

It matters not what version of macOS we are talking about.

If you are on a previous OS, you will see an "Upgrade" available for the most current OS (Catalina in this case). An Upgrade is always the most current version of that OS. You can also get that from the App Store.

If you are on a particular version of the current major OS release, but not the most current version, you will see an "Update" that will take your current installed version of that OS to the most current version.

In both cases, the most current version is 10.15.4 w/Supplemental Update. If you install either the Update or the Upgrade, you will see the version as 10.15.4. It will have a different build number than the original 10.15.4, but that is a horse of another color.

Someone listened..Its fixed!!

They didn't listen to this thread or anything else, here.

It would always eventually get "fixed."

The mass freakout about something so inconsequential was entertaining, though.

Calm down. It was not a mass freakout. One person seems very inclined to use CAPS. Then many of the most recent posters evidently did not bother to read the previous posts before reporting problems that had already been solved. That, in my experience, is par for the course.

Must be just a fluke, I just tested and the Software Update pane will download 10.15.4 just fine. The full installer app will be in /Applications when the download is complete.

I have the exact same problem. OS is the exact same.

Strange ... is there a free-stand download? Afraid to install a "null" ...

That is the "free-stand download."

Same issue here

I have the Exact Same Message! A week or so ago it was ready to go but said 10.15.3. Now it is the same as the snapshot above ??? Not gonna update at this point.

Is this another way to update from Mojave to Catalina. There are no instructions; no explanations of why there are three files. I have only guesses about how to proceed.

What "three files?" There aren't three files. It's a single application that is downloaded.

No, there is no other way to get macOS.
