I have been updating software in the BCRC and Biology computing labs for the fall semester including updates to the MacOS and many software packages, including Adobe Creative Suite, MS OFfice, Firefox, Libreoffice, Scribus, and others. If you notice something not working, please bring it to my attention.
Note that we did not upgrade to the newer versions of the MacOS: We are not using Lion or Mountain Lion. We have several software packages that people depend on that won't work after we update to Lion. And for most things, Snow Leopard (the version we have installed) seems to work better for most people.
