You don’t need to buy an old Macintosh to experience classic Mac OS anymore. In fact, you don’t even need to fiddle around installing an emulator and downloading ROMs. Thanks to a new project, you can boot up every major release of Mac OS from the 1980s and ’90s right in your web browser.

With more than 25 Apple computers and devices in my collection, I’m something of a vintage Mac collector. It’s an expensive hobby that few can indulge in, but the Infinite Mac website lets you experience one of the joys of collecting vintage gear: Taking ancient software for a spin on a vintage Mac.

You could have dozens of copies of the same images in your Photos library, taking up space on your phone and in your iCloud account. Luckily, Apple offers an easy-to-use little tool that lets you find duplicate photos and delete the copies, all right from the Photos app.

Update: In iOS 16.4, released today, duplicates will now be detected between Shared iCloud Photo Libraries. If you have this set up, check for duplicates again — there’s likely to be hundreds more after updating.

These types of duplicate images can accumulate more quickly than you might expect. They arise if you make a copy of a photo to edit, if you screenshot a photo to bump it to the top of your Camera Roll, or if you and your partner both upload the same picture to your Shared iCloud Photo Library. In fact, I found hundreds of duplicates in my own carefully curated library.

It’s a surprisingly sophisticated feature that took Apple engineers a fair amount of smarts to cook up (more on that later). Here’s how to use Apple’s duplicate image remover and get rid of all those unnecessary files.

The wait is over for macOS Ventura 13.3 and iPadOS 16.4, which Apple released Monday. While not major upgrades, they do bring new emoji, a better way for devs to work with betas, and other changes (including security updates).

Apple also released iOS 16.4, as well as watchOS 9.4 and tvOS 16.4, today.

I occasionally run across someone criticizing Apple because MacBook Pro supports only a single external display. But that’s a limitation of only a couple of MBP models — most recent ones can connect to many more.

It affected the first professional-grade MacBook with Apple silicon, which is probably why people are still confused today. Current models support two or more external screens, with one weird exception.

Some software is just essential. And until April 3 at 11:59 p.m. Pacific, we’ve got a great deal on one of computing’s bedrock software suites: Microsoft Office Pro for Mac or Windows. This multi-app bundle comes with the software that functionally runs the professional world.

Right now, a lifetime license to these essential Microsoft Office programs is on sale for just $39.97 (regularly $349) during our Spring Digital Blowout sale.

March 23, 1992: The “headless” Macintosh LC II arrives, wooing value-oriented customers with a beguiling mix of updated internals and budget pricing.

Designed to take up minimal space underneath a monitor (sold separately), the Mac LC II is destined to become a hit. In retrospect, the entry-level machine is roughly analogous to today’s Mac mini.

Mac users get plenty out of their computers, but things can get a little complicated when trying to incorporate Windows software. Now, you can eliminate those frustrations and maximize your Mac experience by picking up a subscription that supplies seamless access to your favorite Windows apps.

For those tired of the slowness of running Windows software on their Mac, meet the CrossOver Windows compatibility app. You can get a one-year subscription to it for only $49 (regularly $74). You won’t find a better price than this anywhere on the web.

I always use Apple’s privacy-focused Sign in with Apple and Hide My Email services whenever I get the option.

The Sign in with Apple feature, which lets you log into third-party accounts using your Apple ID while keeping your personal info private, is so easy to use that I utilize it everywhere. But that also means my disguised logins pile up, accumulating in the digital junk drawer that is iCloud Settings.

I’ll show you where you can find, manage or delete these accounts. Perhaps you’re jumping ship from iPhone to Android, and you want to make sure you still have another way of signing into your Chipotle account.

The Hide My Email service is similar. It creates a temporary email address that forwards to your real one — handy if you’re signing up for a shady website, or if you need a public contact email. I’ll show you where you can create new ones and delete the old ones.

March 19, 1990: The ultra-fast Macintosh IIfx makes its debut, sporting a hefty price tag appropriate for such a speedy machine.

The fastest Macintosh of its day, it boasts a CPU running at a “wicked fast” 40 MHz. It gains an additional speed bump from a pair of Apple-designed, application-specific integrated circuits. Prices start at $9,870 and run up to $12,000 — the equivalent of $22,718 to $27,621 in 2023 money!

The Apple TV app for macOS is reportedly about to get a redesign that includes a left sidebar. That will apparently make it nearly identical to the iPad version.

The update might debut in macOS Ventura 13.3, which is currently in beta.
