Call or visit the lab and ask the consultant for specifics. Some software doesn't work on some machines while it does work on others. Ask the consultant on duty about the machine and software you want to use. Please bring your own. The equipment and network are fairly old and slow by modern standards.
Patience is a requirement.
The Macs have a hard time keeping track of where things are in a server environment like we use in the labs, so double-clicking on documents and aliases isn' t always reliable. Sometimes double-clicking on a file a second time will make it work. If you use the same lab you can make your own aliases and you'll always be able to get into the proper folder when you come to the lab, except when we rename or move things, which happens from time to time.
