Thanks for reaching out to us, @bryan-solidrockc.
 

We're always here to help. However, we require additional information so we can understand the issue better and provide an accurate resolution.
 

May I ask what specific issues did you encounter in QuickBooks Online (QBO) after the Mac update? We'd also appreciate it if you could share more details about the printing problem you experienced. Feel free to include screenshots as well so we can have a visual reference of the error.
 

We're looking forward to your response, Bryan. Just leave your reply below, and we'll chime in right away to provide further assistance. Keep safe and have a wonderful rest of the day!
