Google Calendar notifications not popping up: what to check, in order

When Google Calendar notifications stop popping up on a computer, the cause is almost always one of four switches, and they sit in four different places: the Notifications setting inside Google Calendar, the browser's permission for calendar.google.com, the operating system's notification settings for the browser, and a Focus or Do Not Disturb mode. A fifth condition catches many people out: Google states that desktop notifications only appear while Google Calendar is still open in a browser. Close the tab, and the pop-ups stop.

The checks below go in the order that rules out the most causes fastest. Menu names are taken from Google's and Apple's help pages as they read on October 18, 2026, and the Mac steps match macOS 27 and macOS Tahoe 26.

First, know which kind of notification is missing

Google Calendar on the web sends notifications in three forms. Google's help page on changing Google Calendar notifications defines them this way:

Type	Where it appears	What it needs
Desktop notifications	Outside the browser window, as a system pop-up	Calendar open in a browser tab, browser permission, system permission
Alerts	Inside the Google Calendar window	Calendar open in a browser tab
Email	In the inbox	Nothing on the computer side

"Not popping up" almost always means desktop notifications. That narrows things down. If an email reminder arrives but no pop-up does, the event and its reminder are fine, and the problem is somewhere between the browser and the screen. If neither arrives, start with the event's own notification settings in the next section.

Phone notifications are a separate system. The Google Calendar app on iPhone or Android sends its own notifications through the phone's settings, so a working phone and a silent computer, or the reverse, is normal and points at the device that is silent.

Check 1: the setting inside Google Calendar

Start at the source, because nothing downstream helps if Calendar is not trying to send anything.

1. Open Google Calendar on a computer.
2. Click the Settings menu at the top right, then Settings.
3. On the left, under General, click Notification settings.
4. Open the Notifications drop-down and choose Desktop notifications.

Google notes that the setting can only be changed in a web browser such as Chrome or Safari, and that if the browser asks whether to let "calendar.google.com" show notifications, it has to be allowed.

On the same screen there is a checkbox that silently removes many notifications: Notify me only if I have responded Yes or Maybe. When it is ticked, any event that has not been answered gets no notification at all. Invitations accepted from an email client sometimes do not register a response in Calendar, so this box can make a whole category of meetings go quiet. Untick it if unanswered events should still alert.

Next, check the calendar and the event:

• The calendar's defaults. Under Settings for my calendars on the left, click the calendar, and look at Event notifications and All-day event notifications. These defaults apply to new events. A calendar with no default notification creates events with no reminder.
• The event itself. Open the event, click Edit event, and look next to Notifications. Each event can override the calendar default. Choose notification rather than email, and set how far in advance.

Google also points out a case that cannot be fixed by settings: on a work or school account, when an administrator changes an event on a user's calendar, the user does not get a notification about that change.

Check 2: the browser's permission for calendar.google.com

If Calendar is set to send desktop notifications but nothing appears, the browser may be blocking the site. Google's help page gives the Chrome steps:

1. Open Chrome.
2. Click More at the top right, then Settings.
3. Click Privacy and security, then Site settings, then Notifications.
4. Next to "Allowed to send notifications," click Add.
5. Enter "calendar.google.com" and click Add.

Two details are worth checking while that page is open. First, look at the "Not allowed to send notifications" list. If calendar.google.com is there, a past click on Block is the whole problem, and it needs to be removed from that list. Second, Chrome can use quieter notification prompts for sites, which means the permission request may never have been shown in the first place. Adding the site manually avoids that.

For Safari, Firefox, and Edge, Google's advice is the same in principle: open the browser's notification preferences and add a permission for calendar.google.com. In Safari, that is Safari > Settings > Websites > Notifications, where calendar.google.com should be set to Allow.

Google mentions one more browser difference: snoozing notifications only works in Chrome. If a snooze button is missing in another browser, that is expected behavior, not a fault.

Check 3: macOS notification settings for the browser

This is the step most guides skip, and on a Mac it is the most common cause once the first two are fine. The browser can be allowed to show notifications for calendar.google.com while macOS itself is blocking the browser from showing anything.

Apple's page on Notifications settings on Mac describes the path: choose Apple menu > System Settings, then click Notifications in the sidebar. Under Application Notifications, find the browser, for example Google Chrome or Safari, and click it.

Check these options for the browser:

• Allow notifications must be on. When it is off, every other option on that screen is dimmed.
• Desktop must be selected among the places notifications appear. If only Notification Center is selected, notifications are filed in the list without popping up, which looks exactly like "not popping up."
• The style. Apple lists two styles. Temporary notifications disappear after a while. Persistent notifications stay on screen until dismissed. Someone who often misses a pop-up that vanished while they were looking elsewhere should choose Persistent.

On the main Notifications screen, there are also three settings under Notification Center: show notifications when the display is sleeping, when the screen is locked, and when mirroring or sharing the display. The last one matters for anyone who presents. When it is set to Notifications Off, which suits screen sharing, reminders for the next meeting will not appear while the screen is being shared.

Check 4: Focus and Do Not Disturb

A Focus mode on a Mac silences notifications from apps that are not on its allowed list. A browser is rarely on that list, so Calendar pop-ups disappear as soon as a Focus such as Work or Do Not Disturb turns on.

The quickest test is to open Control Center in the menu bar and look at the Focus button. If a Focus is active, turn it off and wait for the next reminder. If the reminders return, either add the browser to the Focus's allowed apps in System Settings > Focus, or accept that Focus is doing its job during those hours.

Focus modes can also be shared across devices. When a Focus is turned on from an iPhone signed in to the same Apple Account, it can turn on for the Mac as well, which explains pop-ups that vanish on a Mac nobody touched. The share setting is in System Settings > Focus.

Scheduled Focus modes deserve a look too. A Focus that turns on every weekday at 9:00 will make Calendar pop-ups disappear at the start of every working day, which is exactly when most meeting reminders fire.

Check 5: the tab, sleep, and other conditions that silence pop-ups

Google's own checklist ends with a condition that is easy to overlook: Google Calendar has to still be open in the web browser. Desktop notifications are generated by the open Calendar page. If the tab is closed, the browser has quit, or the Mac has been asleep, nothing is running to send the pop-up. Several everyday situations break this condition:

• Closing the tab at the end of the day. The next morning's first reminder will not appear until Calendar is opened again.
• Tab memory saving. Browsers can put inactive tabs to sleep to save memory. In Chrome, Memory Saver can discard a background tab. Adding calendar.google.com to Chrome's list of sites that always stay active, under Settings > Performance, keeps the tab running.
• Sleep and lid closed. A sleeping Mac sends nothing. Reminders that were due while it slept will not catch up as pop-ups.
• Multiple accounts. A notification only comes from the account whose Calendar tab is open. Someone with a work and a personal Google account open in different profiles needs both tabs open, and each profile has its own site permissions.

There is also a quieter cause for missing notifications about invitations rather than event reminders. Google Workspace's troubleshooting article Not receiving Google Calendar event notifications says that notifications for new, changed, or canceled invitations depend on the default notification settings. In Calendar, those are under the calendar's settings, in the section called Other notifications, where each category such as Changed events or Event responses can be set to Email or None.

When the browser is not the right place for reminders

All five checks above come back to one design fact: Google Calendar on the web only notifies while a browser tab is open and awake. For people whose day is mostly meetings, that dependency is the weak point. Closing the browser to free memory, restarting for an update, or opening a fresh profile all stop reminders without any warning.

There are two common ways to move reminders out of the browser. The first is to rely on the Google Calendar app on the phone, which sends notifications through the phone even when no computer is open. The second is to use a calendar app for Mac that syncs with Google Calendar and sends reminders as native macOS notifications. A native app appears in System Settings > Notifications under its own name, so it can be given its own style, its own place on the Focus allow list, and its own setting while sharing the screen, without changing anything about the browser.

One example on this site sends event alerts as macOS notifications, with the number of minutes set per event or as a calendar default, and for events with a location it can also send a "time to leave" notification based on the travel time from the previous place. The Travel time section of the guide explains how that is worked out, and the Features page lists the rest. The notification settings described in Check 3 and Check 4 apply to any such app in the same way.

What to change first

Open Google Calendar's Notification settings and confirm Desktop notifications is chosen and the Notify me only if I have responded Yes or Maybe box is clear. Then open System Settings > Notifications, find the browser, and make sure Allow notifications and Desktop are both on. If reminders still stop whenever the tab is closed, consider moving them to a native app such as Caltimate.
