Has anyone figured out a workaround? I recently switched to mac and it’s really frustrating to copy data across mutliple tabs instead of windows.
Hello @GutmenschAlex
We are still working on the mentioned feature in this thread.
Please accept our sincere apologies for the length of the situation. We will update this thread once we have something to share.
I am finding that franswateebo’s workaround is working for me on macOS
open -na "OnlyOffice"
https://ss64.com/mac/open.html
It does create multiple instances, but the RAM overhead is tiny (50-60MB), compared to what I was experiencing with my previous office product (WPS). The residual headache is keeping track of the multiple instances, and perhaps the arguable clutter in the macOS dock. Otherwise seems to do the job.
Stay FOSSy.
macOS 12.7.6
OnlyOffice 8.1.1
