Hi, I unfortunately couldn't find good data on the current Intel/Mac market share, but isn't it a bit too soon?
The requirement for x86_64 is the App Store was just dropped last month. macOS Tahoe will get support for several more years (My guess would be 2028). It would be unfortunate if Qt users who still need to support x86_64 would have to stick to 6.12 (in the worst case that it breaks in >= 6.13 and nobody fixes it). Is there the option to move macos/Intel to a lower tier with less frequent builds, to reduce the CI load? — Frank Gonçalves Osterfeld | [email protected] | Senior Software Engineer & Teamlead KDAB (Deutschland) GmbH, a KDAB Group Company Tel: +49-30-521325470 KDAB - Trusted Software Excellence > On 5.
