MacOS Monterey & OneDrive issues Does anyone have an issue with opening OneDrive documents across their Apple devices? Either one of the two errors pop up when I attempt to open a file on my (2018) Macbook Pro’s OneDrive (my (2021) iMac’s OneDrive works fine when I do the same though). The error will either say “Couldn’t communicate with helper application” OR it will say “File x could not be opened. It may be damaged or use a file format that Preview doesn’t recognize”. For me, I have checked the syncing, updating iMac and Macbook Pro to Monterey 12.5.1, uninstalling and reinstalling OneDrive, checking permissions, restarting my devices...and there is still the same issue. I work on my laptop on the go, (sometimes I’ll have wifi and sometimes not) and when at home I work on my iMac. It is super inconvenient to go onto the web, log into OneDrive and search for and download x files onto my Macbook Pro just to access and work on a document. The point of having the OneDrive app on a desktop and laptop is so that it can sync together and be accessible on your devices when needed. I have been encountering this issue the past few months. Hoping someone can help or offer solutions! Thank you in advance!!

Error: "Couldn’t communicate with a helper application" when trying to compress files Suddenly when I try to compress files I receive the message 'Couldn’t communicate with a helper application.' In a previous post, it was recommended to change the Read and Write setting in the Get Info box. I made those changes and it did not make a difference. I have also updated my computer and it has not fixed the issue. I am currently having to copy folders onto a flash drive and transfer them to a PC to then compile and send which is quite frustrating. I am using Mac Ventura Version 13.3.1
