macOS 27 Intel Macs: The End of the Road for Rosetta

<!– wp:paragraph –>
<p>macOS 27 ‘Golden Gate’ is Apple silicon only, and it’s also the last release with general-purpose Rosetta 2 support. Here’s exactly which macOS 27 Intel Macs are affected and what to do before you’re caught out.</p>

<p>macOS 27 supports only Apple silicon Macs – no Intel model qualifies, full stop. Apple’s own compatibility list covers Apple silicon MacBook Air and MacBook Pro from 2020 onward, iMac from 2021, Mac mini from 2020, Mac Studio from 2022, and Mac Pro from 2023.</p>

<p>One wrinkle worth knowing: a 2020 MacBook Air, Mac mini or MacBook Pro only qualifies if it’s the Apple silicon (M1) model. Intel versions of those same machines, sold in that same year, are excluded. If you’re not certain which chip your 2020 Mac has, check About This Mac before assuming either way.</p>

<p>The specific Intel models that macOS 26 Tahoe supported, and that macOS 27 drops, are the 16-inch MacBook Pro (2019), the 13-inch MacBook Pro with four Thunderbolt 3 ports (2020), the 27-inch iMac (2020), and the Mac Pro (2019). Those machines simply stop at Tahoe – they’ll keep getting Tahoe security updates for a while, but no new macOS version.</p>

<h2 class=”wp-block-heading”>Rosetta 2 is also on its way out</h2>

<p>Separately from the hardware cutoff, macOS 27 is the last release with general-purpose Rosetta 2 support for running Intel-only apps on Apple silicon. Reporting differs slightly on the exact mechanics – one account says a limited Rosetta subset survives into macOS 28 purely for older, unmaintained games that depend on Intel-based frameworks, while general-purpose Intel app support ends with Golden Gate. Treat the precise detail as unconfirmed until Apple’s own release notes for macOS 27 are out, but the direction is consistent across sources: Intel app compatibility is closing, not staying open indefinitely.</p>

<p>Apple has already been laying groundwork for this. macOS 26.4 and 26.5 started showing a warning dialog the first time you launch an Intel-only app, flagging that support is ending in a future release – so if you’ve seen that prompt already, this is what it was warning you about.</p>

<h2 class=”wp-block-heading”>What to actually do about it</h2>

<!– wp:list {“ordered”:true} –>
<ol class=”wp-block-list”><!– wp:list-item –>
<li><strong>Check which chip you have.</strong> Apple menu → About This Mac. If it says an Intel processor, macOS 27 isn’t coming to that machine.</li>
<!– /wp:list-item –><!– wp:list-item –>
<li><strong>Audit your Intel-only apps now, not after the warning dialog starts appearing everywhere.</strong> Open Activity Monitor’s CPU tab and check the “Kind” column – anything listed as “Intel” rather than “Apple” is running under Rosetta today and needs a native build or a replacement before general Rosetta support ends.</li>
<!– /wp:list-item –><!– wp:list-item –>
<li><strong>If you’re on an excluded Intel Mac,</strong> macOS 26 Tahoe is your last stop – it’ll keep receiving security updates for a while on Apple’s usual schedule, so there’s no immediate rush, but plan hardware replacement around that timeline rather than after it lapses.</li>
<!– /wp:list-item –><!– wp:list-item –>
<li><strong>If you’re on Apple silicon already,</strong> the main action is just making sure any Intel-only software you still rely on has a native alternative lined up before you update.</li>
<!– /wp:list-item –></ol>

<!– wp:paragraph –>
<p>None of this is urgent today for every macOS 27 Intel Macs owner, but it’s exactly the kind of cutoff that’s easy to ignore until an app suddenly won’t launch after an update. A five-minute audit now beats discovering it the hard way.</p>
