I attempted to open Console and figure out what the error was but I was unable to find anything in Console’s Crash Reports during a cursory search.

For reference, I am running the latest version of Insync (Version

This error occurs when I attempted to launch Insync for the first time (this was a fresh install).


Thanks for the heads up! Will notify our Mac team regarding this.

Same with me, I emailed support as well and they are looking into it.

Any update on when this will be fixed? I’m having issues where my files are not in sync with MacOS Big Sur.

Hello, how are you? it would be very good to at least get a solution preview or even try the solution because we are facing problems with the synchronization of the files, we know that the version is beta but other app providers are already approving for a new version of macOS. We are waiting for a return from you …

Hello devteam have a good news for we about Big Sur. I wait this for purchage other license for my OneDrive, i want put Google Drive and OneDrive in my MacBook.

Help please.

Looking forward to some sort of update.

Hey guys! Appreciate all the +1s to this. Our Mac team has been working on Big Sur support-- could you check out 3.2.6 and let us know if the crashing issue persists?

Dear @mia

This seems not to work. At least not for me.
After updating Insync nothing happens. The icons changes to the green checkmark status, but nothing has been synced.

Are there still any issues with this version?

Hi @mia,

I can confirm, that I am on 3.2.7:

But I have not been “autoupdated”.
Anyhow, I will try to do a fresh re-install…



Good news, @mia.

Did a CleanMyMay with Insync and a fresh reinstall on Big Sur.
Sync works again now!

Thans for your assistance
