Install a JDK
This is a chestnut but I keep getting the "you need to install a JDK" error message on my new iMac running Catalina.
When I try to install the Java legacy software (cf various other threads on same topic) I get the message below (Java for Mac OS 2017-001 can't be installed on this disk. A newer version of this package is already installed).
To date, I have tried to uninstall the current Java, reinstall the legacy Java and then reinstall the latest Java, both with Java's now uninstall program and Mac Terminal.
It still won't let me reinstall the legacy Java. On restart, and with no apps running, I still get the message below.
Does anyone have any bright ideas, please? Even isolating the code/app that's looking for the legacy Java would be good.
Best wishes,
cata
