Unable to open Numbers file on iMac
I'm trying to open a Numbers file on my iMac that I just used last week but continue to get the following message: "Numbers couldn’t read the file. You can try restoring to a previous version." I click on Browse Old Versions and it says there are none available and then "operation not permitted". I am able to open the file on my MacBook Pro without any issues but how can I get this file to open again on my iMac??? The file is saved in iCloud.
