OpenAI's official ChatGPT app for macOS is now available to all users for the first time, provided they're running macOS Sonoma or later.

It was previously being rolled out gradually to paid subscribers to ChatGPT's Plus premium plan.

The ChatGPT Mac app mostly acts as a desktop window version of the web app, allowing you to carry on back-and-forth prompt-and-response conversations. You can select between the GPT-3.5, GPT-4, and GPT-4o models. It also supports the more specialized GPTs available in the web version, including the DALL-E image generator and custom GPTs.

As the Intel Mac era has wound down over the last couple of years, we've been painstakingly tracking the amount of software support that each outgoing model is getting. We did this to establish, with over 20 years' worth of hard data, whether Intel Mac owners were getting short shrift as Apple shifted its focus to Apple Silicon hardware and to software that leveraged Apple Silicon-exclusive capabilities.

So far, we've found that owners of Intel Macs made in the mid-to-late 2010s are definitely getting fewer major macOS updates and fewer years' worth of security updates than owners of Intel Macs made in the late 2000s and early 2010s but that these systems are still getting more generous support than old PowerPC Macs did after Apple switched to Intel's processors.

The good news with the macOS 15 Sequoia release is that Apple is dropping very few Intel Mac models this year, a much-needed pause that slows the steady acceleration of support-dropping we've seen over the last few macOS releases.

We’ve written before about Apple’s handy virtualization framework in recent versions of macOS, which allows users of Apple Silicon Macs with sufficient RAM to easily set up macOS and Linux virtual machines using a number of lightweight third-party apps. This is useful for anyone who needs to test software in multiple macOS versions but doesn’t own a fleet of Mac hardware or multiple boot partitions. (Intel Macs support the virtualization framework, too, but only for Linux VMs, making it less useful.)

But up until now, you haven’t been able to sign into iCloud using macOS on a VM. This made the feature less useful for developers or users hoping to test iCloud features in macOS, or whose apps rely on some kind of syncing with iCloud, or people who just wanted easy access to their iCloud data from within a VM.

This limitation is going away in macOS 15 Sequoia, according to developer documentation that Apple released yesterday. As long as your host operating system is macOS 15 or newer and your guest operating system is macOS 15 or newer, VMs will now be able to sign into and use iCloud and other Apple ID-related services just as they would when running directly on the hardware.
