On a preliminary test on our two Macs running 10.11.6 and Suitcase Fusion 18.2.1, this has resolved our issue with not being able to open Office product files due to what the programs called permissions issues. After months
of struggling on brand new machines...thank you!
In the past, a restart would solve the issue temporarily, so I am interested to see if this resolves it permanently in our case! (Logic would point to the conclusion that it very well could, with the way sandboxing seems to work.)
That's excellent news, I'm glad it helped you out. Please report back if the issue comes back, we all need as much info as possible to pinpoint this problem.
I will be conducting more research this week to see if I can come to similar conclusions.
