Cannot open numbers spreadsheet on my MacBook Pro 2011
Is there a way to update my Numbers 3.6.2 (2577) on my MacBook Pro mid 2011 (ElCapitan v 10.11.6)? I'm getting the message that an update is required when I try to open certain spreadsheets..."It's Time To Update...To open this spreadsheet, you’ll need the latest version of Numbers."
