Ever have a problem on your Mac, where you can’t type the letters and numbers 7, 8, 9, U, I, O, J, K, L, and M—and maybe some others?

It’s probably Mouse Keys at play, an accessibility feature in macOS that mimics an old IBM-style keypad feature.

Num Lock and its computer history

Keyboards still have vestiges of their origins on typewriters and mechanical calculators. We mostly ignore those in our day-to-day work. The Shift key, originally meant to literally raise a set of typebars in a typewriter, merely shifts among upper and lower case. And you know better than to press Caps Lock when entering passwords—Apple even alerts you when you have it accidentally enabled.

The Num Lock key was a product of the intermediate age, where mechanical and digital met. Some IBM computer keyboards didn’t have separate arrow keys, but they did have a numeric keypad for fast number entry. IBM doubled up: It added a Num Lock key that flipped the numeric keypad to act as arrow keys to move a cursor around a screen-based interface, before computer mouses.

On certain laptops, including older Macs, Num Lock had a different function. Lacking a numeric keypad, Num Lock turned part of the main keyboard into a pseudo-keypad. (There was sometimes a unique Num Lock key, sometimes it doubled with a Clear key and Shift, and sometimes it was a function to invoke, like through F6 on a Mac.)

The pseudo-keypad layout relied on sets of four keys starting with 7, 8, 9, 0 and going down three rows to M. With this mode invoked, you could still type 7, 8, 9, and 0 and have those characters appear, as they’re still mapped to the same position. But U, I, O, P, J, K, l, semicolon, M, command, period, slash take on keypad functions.

Apple stopped supporting Num Lock via F6 quietly back in 2008. It shouldn’t be possible to invoke this mode accidentally, as it shouldn’t exist. It’s available in Boot Camp with some laptops, although Apple doesn’t specify which.

An independent developer did create a Num Lock app—called simply NumLock—that would invoke the feature within Mac OS X; it hasn’t been updated in a few years, and I haven’t tested it in Mojave.

Mouse Keys and its modern usage

Apple lets you hearken back to those IBM days with an accessibility feature in macOS called Mouse Keys. With Mouse Keys enabled in the Accessibility preference pane in the Mouse & Trackpad section, the number keys on a keypad turn into cursor diagonal, left, right, up, and down cursor movement in tiny increments—or hold down and it moves faster. To click the mouse, press 5; to click and hold, press 0; to release, press the dot on the keypad.

However, if you’re using a laptop or a keyboard without a keypad, Mouse Keys hijacks a subset of that old IBM layout. 7, 8, 9, I, O, P, J, K, L, M, and period are turned into the same layout as a keypad (789/456/123/0.).

One Macworld reader has found that a keyboard they plugged in invoked Mouse Keys even though they didn’t know it was turned on. You can disable Mouse Keys via the Accessibility preference pane, but if you haven’t changed defaults, you can also tap the Option key five times and an onscreen accessibility message appears briefly noting it’s turned off. You can similarly re-enable it the same way.

Both Safari and Chrome browsers on your Mac allow websites to send Push Notification Pop-ups, asking whether they would like to allow or Enable Push Notifications for the website.

Disable Push Notifications From Websites On Mac

As soon as you start browsing any website on your Mac, you will immediately see a pop-up, prompting you to either Allow or Deny Notifications from the particular website that you are trying to browse.

In case you click on Allow, you will start getting Notifications from the website, every time a new article is published on that website. As you can imagine, this feature in Safari and Chrome Browsers is good for website owners and it allows them to reach their readers.

However, the problem with this feature is that these pop-ups never stop and you will continue to get these Push Notification Pop-ups even if you click on the Deny option.

Hence, the only way to stop Push Notification pop-ups from appearing on your Mac is to completely disable this feature on Safari and Chrome browsers on your Mac.

Disable Push Notifications Pop-ups in Safari Browser
