Cannot install MacOS-10.14.4

[Yang]

Hello,

I have a naive question on the installation of the new version MacOS-10.14.4. My Mac system is x86_64 10.14.6, and when I try to install the Macaulay2 MacOS-10.14.4, the following message always appear. The same problem appears too when I try 10.14.2 and 10.13.5. On the other hand, I tried very early versions, like 1.6 and 1.9.2, there is no any problems. Could someone give me some advice? Thanks a lot in advance!

This is a bug in Macaulay2 : you have previously used "installPackage" to install the package 

"Polyhedra".  But now that old version of "Polyhedra" is incompatible with the new version of Macaulay2.
The bug is that it gets loaded from your home directory application directory instead of from the files that

come with 1.14.  You could start M2 with "-q" on the command line to avoid the error, or you could run

uninstallPackage "Polyhedra"

to get rid of that old installation.

I've reported the bug here: https://github.com/Macaulay2/M2/issues/1032
