19 useful Mac startup keyboard shortcuts you should know

Christian Zibreg ∙ Updated July 14, 2022

For those of you who have wondered about the many ways you can start up your Mac, here's a list of the Mac startup keyboard shortcuts you can invoke to access handy macOS features, which are only available at boot time.

Most of the time, your Mac just works—until it refuses to start up properly due to an unforeseen system error, a misbehaving app, a broken system component, and whatnot. Beyond system errors, different people have different needs when it comes to starting up their computers.

For example, you could be a pro user who dual boots between macOS and Windows on a daily basis. Others might wonder about booting a Mac from a disk other than their designated startup disk. Or perhaps you're looking to isolate the cause of a software issue in the macOS Safe Mode or boot straight into Recovery OS as the last option?

How to find the RGB or Hexadecimal value of any pixel on Mac

Anthony Bouchard ∙ Updated October 10, 2023

RGB, otherwise known as red/green/blue, is a color identification method used by digital computer monitors. Every color gets its own RGB value, and this is because a mixture of those three colors makes up the color you're looking at.

RGB values may be used for a variety of reasons, but mostly for those that do a lot of photo editing or who may be tinkering with graphics or web design.

A little-known feature of your Mac is that its operating system comes with a meter that can identify the RGB color of any single pixel on your screen, and in this tutorial, we'll show you just how that's done.

It's somewhat depressing that Android manufacturers increasingly outfit their flagship smartphones with fast-charging capability while iPhones, and especially iPads, still take forever to charge from zero to hundred percent.

iTunes tip: see Apple Music songs in your library that are no longer available for streaming

Christian Zibreg ∙ May 18, 2016

The biggest problem with subscription services like Apple Music, Spotify and others is the unnerving fact that labels make songs available for streaming on a time-limited basis. As a result, some of the tracks you add to Apple Music playlists may no longer be available for streaming, leaving you with no other choice but to purchase them on the iTunes Store.

Starting with iTunes 12.4, there's a new iCloud status of 'No Longer Available' which you can use to create a dynamically updated playlist containing the songs that you added to your Apple Music library that are no longer available for streaming, here's how.

Manually checking for Java updates for your Mac or PC

Anthony Bouchard ∙ Updated July 19, 2018

Java, just like Adobe Flash, is often a major security flaw waiting to happen for both Mac and PC owners.

Although Apple takes security very seriously and just about forces Mac users with Java to check for Java updates automatically, it's still never a bad idea to check on your own from time to time.

Since we recently showed you how to check for Flash updates manually, it only made sense to follow up with a similar guide for Java, which is also a commonly-used web plugin.

In this tutorial, we'll show you how to see if you have the latest version of Java installed on your computer or not.

Christian Zibreg ∙ May 17, 2016

SnapBack, a long-standing and very easily overlooked Safari for Mac feature, can save you a ton of clicks if you search a lot, and most of us do. With SnapBack, you can go right back to the last full search results page, even after traveling multiple pages in from your search results.

Part of the reason most users aren't familiar with SnapBack has to do with Apple's decision to remove the little orange SnapBack icon from Safari's address bar and bury the feature in the menus.

Here's that secret SnapBack shortcut that everyone should start using right now.
