First, I was satisfied, even if the presentation does not look as chic as the normal Office for Windows and the programs frequently have even hung. After an update of the Mac operating system, the office suite does not work anymore, unfortunately. Reinstall did nothing. I waited for months and tried to reopen it for further updates, or to update Office, but all failed. I am now switched to OpenOffice, have not tired of the office problems. For the price this is simply not acceptable !!!
