Occasionally, when trying to open a file or document library in one of our SharePoint sites, instead of opening the file/folder, SharePoint prompts the user to download a file named "preload" (Speicific message - "Do you want to download "preload"?"). If the file is downloaded, then the downloaded file is empty; it has no file extension, is 0 KB large, and opening it in NotePad opens a blank window. This issue does not lock users out of files or folders - when attempting to open the file or folder again, then the user is able to open the file/folder without issue.Currently this issue has only been observed on Apple devices and only while using Safari. Efforts to recreate problem on Windows/Firefox and iOS/Safari/Different SP site have been fruitless.Could this be an issue with the specific SharePoint site or a general Apple-wide problem with SharePoint Online?

I am facing the same issue, which is overall annoying and don't know how to make it stop.
I don't think this is a specific tenant issue, same experience here. I *can* use Chrome, but I am using Safari for everything else and it is embedded in my way of working, so it would be great if this could be addressed.
I am not experiencing similar issues outside of Sharepoint/OneDrive. Outlook, PowerBI, Project etc. are all working fine.
Same issue on Safari, 0kb "preload" file downloaded when opening Sharepoint. Others using Chrome don't have it.
me too. why is microsoft preloading spyware on the mac? are u collecting data?
Same issue here. It’s not a tenant issue. We don’t know whether it’s a change on Safari or something MS have done. Either way it needs sorting. There are enough infuriating things with Sharepoint without this!
