It seems like you're facing an issue with your macOS Calendar subscriptions after migrating to your M2 Pro Mac mini. Here are some steps you can take to resolve this problem:
1. Check Internet Connection:
Ensure that your Mac mini has a stable internet connection. Calendar subscriptions require an active internet connection to fetch and update data.
2. Update macOS:
Make sure your Mac mini is running the latest version of macOS Ventura. Sometimes, software updates include fixes for issues like this.
3. iCloud Sign-In:
Confirm that you are signed in to iCloud on your Mac mini using the same Apple ID that you use on your iPhone and iPad. This ensures that your calendars remain in sync across your devices.
4. Delete and Re-Add Subscriptions:
Since you've already tried this, you can attempt it again, but with a twist:
- Delete the problematic subscriptions from your macOS Calendar.
- Restart your Mac mini.
- Add the subscriptions again, one at a time, and check if they work after each addition. This will help identify if a specific subscription is causing the issue.
5. Firewall and Security Software:
Check if any firewall or security software on your Mac mini might be blocking Calendar from accessing the internet. Temporarily disabling such software can help diagnose the issue.
6. Keychain Access:
Sometimes, there could be keychain-related issues causing problems with subscriptions. You can try these steps:
- Open "Keychain Access" from Applications > Utilities.
- Search for "iCloud" in the keychain list.
- Delete any keychain entries related to iCloud.
- Restart your Mac mini.
- Re-add the calendar subscriptions.
7. Check iCloud Status:
Occasionally, iCloud services may experience downtime. You can check the status of iCloud services on Apple's System Status page (Apple - Support - System Status). If iCloud Calendar has an issue, you may need to wait until it's resolved.
8. Contact Apple Support:
If none of the above solutions work, it might be beneficial to contact Apple Support. They can provide more specific guidance and assistance, especially if the issue is related to your iCloud account.
Remember to back up any important calendar data before attempting any major changes or contacting support. This way, you can restore your data if necessary.
