Hi there! I see you're having trouble connecting your CHEF iQ probe. To help you best, could you tell me a little more about what's happening? For example, is the probe not connecting at all, or is it intermittently losing connection? Also, are you using the probe with the CHEF iQ app on your Mac running OS X 10.15.7?

Once I have a bit more detail, I can guide you step-by-step to try to resolve the issue. Meanwhile, here are some general quick checks we can start with:

1. Make sure the probe and its connector are clean and free from any food residue or debris which might block proper contact.
2. Check if the probe’s batteries (if it requires any) are fresh or fully charged.
3. Restart/power cycle the probe and the Smart Hub or base unit—turn them off, wait a few seconds, then back on.
4. Ensure your Mac’s Bluetooth and/or Wi-Fi (whichever is used for the connection) is enabled and working fine.

Could you try these and let me know what you observe? Then we can dig a little deeper if needed.

Would you like me to continue guiding you through more specific troubleshooting steps based on these initial checks?
