Is there a way to find out which apps already installed on my Mac with High Sierra will potentially have problems with Mojave.

Before trying to figure out the sometimes hard to understand messages and errors occurring after Mojave install.

Some examples of frustration finding it afterwards...

GarageBand stopped recognizing my piano/keyboard after installing MacOS Mojave

or others not always pre-installed app or hardware related https://apple.stackexchange.com/questions/tagged/mojave

Please edit the question to limit it to a specific problem with enough detail to identify an adequate answer. Avoid asking multiple distinct questions at once. See the How to Ask page for help clarifying this question. If this question can be reworded to fit the rules in the help center, please edit the question.

    How about you share a list of installed app (or just the app you think could possibly not run as they are no longer actively developed) and folks who have them installed share their feedback? The way it is put currently, the query is very broad and may not end up being helpful (for your case). – Nimesh Neema Sep 26 '18 at 7:03
  • We stopped doing this kind of "list" questions a while ago as they didn't really work very well on the long run. Asking for apps which don't work with Mojave doesn't provide useful information on the long run, nobody will come back and update their answer in case an update makes the app run, and there are sites out there who take care of maintaining such lists. – nohillside Sep 27 '18 at 20:09
  • @nohillside Just trying to spare the ppl the frustration of things not working after upgrade. This site is full of that kind of questions at the moment. – Ruskes Sep 27 '18 at 20:17
  • There are some (few) specific questions about issues with specific applications, which is fine. If you want to make a case for a more welcome handling of "list" type questions please raise it on the Meta site. – nohillside Sep 27 '18 at 20:20
  • And the list above is actually a good example for why it doesn't really fit the site: There are at least three applications on the list for which Mojave-ready versions have been available since Monday or before. – nohillside Sep 27 '18 at 20:26

Rule of thumb:

Big applications, professional applications, essential applications and audio applications will not work immediately correctly.

This is just Murphy's law.

Therefore you should wait a bit in principle.

Audio application developers now routinely issue warnings on new macOS releases.

There is no perfect list for this.

But the manufacturer of your software should ideally have a support page on this.

If you insist on a list, then there are the forums at MacRumors, especially MacOS Mojave - App Compatibility

and the almost comprehensive RoaringApps


Apps that don't work at all as of Sep. 26 2018.

    Out of curiosity I looked at my machine and I have only 3 of them; two are fairly obscure or obsolete but the third is Kindle from Amazon (admittedly, I almost never use the Kindle app on the mac, 99% of the time I read books on the iPad). It's mind boggling that a company with as much resources cannot update their app, they will likely wait until the next update when they will be forced to do so :) – rawpower Sep 26 '18 at 8:01

    If Apple says "macOS Mojave is the last release to support 32-bit" then this list you propose is for 10.15, not Mojave. – LangLangC Sep 26 '18 at 9:44

    The transition could still take a while. Also from, support.apple.com/HT208436 When will the 64-bit transition be complete? The 64-bit transition for macOS and macOS apps is still underway, so final transition dates have not yet been established. But now is a good time to check with the software developer to see if 64-bit versions of your favorite titles are available. – Nimesh Neema Sep 26 '18 at 11:09
