Using MapMan

trouble with download for MacOS

trouble with download for MacOS
6/19/20 4:37 PM
I get the error statement:
"MapManInst.app" needs to be updated. The developer of this app needs to update it toward with this version of macOS. Contact the developer for more information. I am using macOS Catalina version 10.15.5.
Two other people I work with have successfully downloaded on their Macs with the same operating system, but for some reason I get this message and the download only get 40.4 MB in the zip file that is downloaded.

I had similar problems with my Mac (also using Catalina). However, I was finally able to install MapMan following these steps:
- download Java 6 SE Legacy (https://support.apple.com/kb/dl1572?locale=en_US)
- however this doesn't run on Catalina on it's own, so that you need to first run the following simple script (copy-paste it on your Script Editor in utility folder):

set theDMG to choose file with prompt "Please select javaforosx.dmg:" of type {"dmg"}
do shell script "hdiutil mount " & quoted form of POSIX path of theDMG
do shell script "pkgutil --expand /Volumes/Java\\ for\\ macOS\\ 2017-001/JavaForOSX.pkg ~/tmp"
do shell script "hdiutil unmount /Volumes/Java\\ for\\ macOS\\ 2017-001/"
do shell script "sed -i '' 's/return false/return true/g' ~/tmp/Distribution"
do shell script "pkgutil --flatten ~/tmp ~/Desktop/Java.pkg"
do shell script "rm -rf ~/tmp"
display dialog "Modified Java.pkg saved on desktop" buttons {"Ok"}

- the script will ask you to choose the file to open so that you can select the previously downloaded java 6, afterwards installation should work fine.
- After installing java (you can check from the terminal by writing "java -version" and the terminal should print the java version), you can download the MapManInst-3_6_0RC1.jar from the download page.
- MacOS doesn't allow installation of software from unknown developers, so you should enable installation from the terminal by writing (do not copy-paste) "sudo spctl --master-disable"
- double click on the downloaded file and it should be installed

Note that no icon will appear on the desktop/application folder. However, the program is installed and located at the following path (unless you changed during installation): "/Applications/MapMan"
You can run the program by writing on your terminal:
"sh ../../Applications/MapMan/MapMan.sh"

This worked for me, there might be easier more straightforward methods I am not aware of. Hope it was useful
