Golden Gate is bringing more than AI. Here are some of the improvements already detailed, some cautions to be aware of, notes on running GG in a VM, Intel support info, and an app update.
Rosetta
Virtualising macOS, Linux and Windows on Intel Macs has been relatively straightforward, and device support left to the developer. That won’t work for Apple silicon Macs. This explains what happens, its strengths and limitations as a result.
Do you still need Rosetta to translate Intel code so it runs on Apple silicon? With macOS 26.4, Rosetta warnings will start, telling that it won’t be available for much longer.
What to do when you know there’s an update available, but Software Update pretends that it can’t find it. With details of undocumented options for softwareupdate command and more.
Apps supplied through the App Store aren’t signed by their developer, but by Apple. Many now have certificates that have expired. When will they stop running?
If you’re still using an Intel Mac, do you know when its macOS support will end? Is it worth upgrading any more when most of the new features are for Apple silicon Macs?
68K to PowerPC in 1994-1998, on to Intel in 2006-2009, and to Apple silicon from 2020. The 68K emulator, Rosetta, and Rosetta 2 that enabled backward compatibility.
Which versions of macOS can run in a VM? Can they run Intel apps too, and Intel macOS? How well do they perform? Can they access iCloud and run App Store apps?
Safari and its supporting frameworks and components, used to be installed in the Data volume, but now come in cryptexes. These also account for the larger macOS updates for Apple silicon.
From Hypervisor APIs in OS X 10.10 Yosemite in 2014, through early VirtIO kernel extensions in Mojave in 2018, and Arm hypervisor support in Big Sur.
