After updating my iMac to Catalina, I realized I needed to download a large number of photos from my Google Photos account, but learned that Backup & Sync from Google is not supported under the new operating system. Searching for help I’ve found only complaints about this same problem. Google had plenty of advance notice that the app needed updating, but there’s no word I can find about when it might finally happen.
Does anyone have a workaround that would allow me to batch-download a bunch of photos from Google Photos to my iMac?
Best I can suggest is to keep trying to isolate variables, such as downloading in another browser, trying in a different user account, and seeing if it’s different on a different Mac.
I finally got the problem resolved after multiple calls to Apple and Google phone support each saying it was the other’s fault. Finally got a Google person to tell me to use Go to Folder and enter ~/Library/Application Support/Google. He had me delete Google Drive and erase it, then re-download Backup & Sync and this time it installed properly and is now running OK.
