Numbers not working on iMac but working on MacBook Pro
I have a 2018 27" iMac and a 2019 MacBook Pro both running the latest OS. Numbers works just fine on The MacBook Pro but not on the iMac. When I try to open an Excel file I either get blank cells or warning symbols but nothing else. I could use the MacBook but I have two large projects for which I need to use the iMac. I've tried trashing my preferences and re-downloading the app but nothing seems to work.
Thanks.
