Subscribe to Syndicate
We have tested Theatre Manager with High Sierra and we have seen limited adverse effects in our test lab. There has been one issue reported to support. Those wishing to update to High Sierra should be ok to do so subject to the following advice:

  • Update one Macintosh at a time.
  • Use that Macintosh for a week with Theatre Manager and all your other applications.
  • Let us know of any issues you encounter with Theatre Manager
  • Once you are satisfied that your first upgraded Macintosh works with all your applications (including Theatre Manager), then do another Macintosh and wait a couple of days
  • Alternatively, wait until version 10.13.02 of High Sierra comes out -- and then start the above process


The only known issue with high sierra is after updating some older mac mini's, printing tickets to an ethernet based ticket printer may cause TM to crash since apple also updated the EFI firmware.

  • High Sierra is a free update to OSX users
  • We suggest users put plans in place to update OSX to High Sierra at a time convenient for your venue if you are using Yosemite or earlier (over the next few weeks to 9 months). There are

    It also means if you are already using El Capitan or Sierra, or High Sierra, you can use both 32 bit or 64 bit Theatre Manager without doing anything to your machines to upgrade them.

For Windows Users, there will also be a 64 bit version of Theatre Manager.
