mac os x: Mathematica 12 compatibility with earlier versions in macOS 10.15 Catalina

I currently run the following:

  • Mathematica 10.3.0.0 in a
  • Mac Pro (late 2013) running
  • macOS Mojave Version 10.14.6.

I want to update the operating system to macOS 10.15 Catalina.

To do this, I understand that I will need to upgrade to Mathematica 12 since Catalina will no longer support previous versions of Mathematica.

Is there any means or are there guidelines to evaluate the compatibility of the code developed in previous versions of Mathematica with Mathematica 12 running in Catalina?

Note: I don't mind updating the code, I only have things that I need to execute during the next month or so. If I need to spend time updating the code for the newest version, I need to plan when I will.

In addition, given the contemplated update of the operating system, I will not have the option of maintaining an earlier version of Mathematica to run what I need until I have everything updated for compatibility.

music.app – macOS Catalina 10.15 music application error

I recently updated to MacOS Catalina and discovered that all my iTunes songs were not there. The files are present in the iTunes folder but every time I play a song, it shows an error. The music library file cannot be saved. An unknown error occurred (-54) appears.

hang – Mail.app and accountsd are taking all Mac OS 10.15 CPUs

Suddenly (I did not see when it is happening and when it is stopping) the CPU peaks, which come from Mail.app and all accounts.

I took a screenshot of the activity monitor, as well as the console, where, when this peak is happening, it is creating +/- 3500 messages per second, all the same as the one shown in the screenshot.

Screen capture activity monitor: https://bazinga.lu/mail1.png
Screen capture console: https://bazinga.lu/mail2.png

Most messages are like this:

Connection error changed for account:

This for all email accounts. Killing all accounts and reading or disabling them didn't help

In addition, another strange thing that happens is that, in the message list, some users (I discovered that they are in the contacts and have a different chain in the contact entry than in the one they provide in the email header) will flash every second of to each other name on this list It is a constant blinking, say every second, a little delayed the further down the list is the mail.

The current "solution" is to stop the mail.app and restart it, it will be good for up to 10 minutes and will happen again.

any ideas ? Started updating from 10.14 to 10.15

Latest version of Mac OS 10.15.1 (19B88)

Thank you

Tom
