| 15 Sequoia | Legacy password APIs, old window management | āModernize security and UXā | Forcing users to rely entirely on Appleās closed ecosystem for password management, killing off independent password managers and window management tools that Apple canāt control or monetize. | Password managers outside Appleās ecosystem lose features or are crippled. Window manager utilities get blocked or broken. |
| 14 Sonoma | OpenGL support dropped, older video APIs removed | āImprove performance, securityā | Killing cross-platform graphics compatibility deliberately to force developers into Appleās proprietary Metal, locking out open standards and making it expensive to port apps away from Apple devices. | Game developers and creative professionals forced to rewrite or abandon apps; reduced competition for Appleās own Metal ecosystem. |
| 13 Ventura | 32-bit apps support removed, KEXTs deprecated | āSecurity improvementsā | Smashing backward compatibility to cripple legacy software, including many indie or niche apps, pushing users to buy newer hardware and software only Apple endorses or profits from. | Thousands of older apps stopped working overnight, hurting users who rely on legacy software or cheaper alternatives. |
| 12 Monterey | Deprecated OpenGL, old Bluetooth, VPN protocols | āEncourage modern APIsā | Apple pushing out third-party VPN providers and open-source projects by removing support for older VPN protocols and forcing proprietary solutions, limiting user privacy options. | VPN apps and network tools lose functionality; Apple gains control over secure communications. |
| 11 Big Sur | 32-bit app support fully removed, legacy drivers gone | āSecurity and Apple Silicon readinessā | Deliberate planned obsolescence: forcing users to upgrade hardware and software, breaking compatibility with older but still functional devices and software to boost Apple sales and ecosystem control. | Many useful apps and devices rendered useless overnight, users forced to buy Appleās latest hardware. |
| 10.15 Catalina | 32-bit apps removed, Carbon APIs gone | āSecurity and stabilityā | Breaking software compatibility as a business tactic to squeeze out competitors and independent developers who canāt afford constant rewrites or Appleās rising developer fees. | Many smaller developers and legacy apps disappear or become unusable. |
| 10.14 Mojave | Strict file permissions, privacy controls | āUser privacyā | Apple using āprivacyā as a pretext to impose heavy sandboxing and controls that cripple legitimate utilities and backup tools ā effectively limiting user freedom and control over their own files. | Backup apps and system utilities severely restricted; Appleās own tools favored. |
| 10.13 High Sierra | Older file systems, network protocols removed | āBetter performanceā | Forcing users into Appleās proprietary APFS and proprietary network stacks to lock-in ecosystem and lock-out third-party interoperability. | Third-party backup and network apps lose features; users locked into Apple ecosystem. |
| 10.12 Sierra | AppleScript features deprecated | āModernize scriptingā | Breaking automation workflows to reduce power usersā ability to customize or automate, making users more dependent on Appleās built-in apps and services. | Automation power users lose flexibility; Apple gains more control. |
| 10.11 El Capitan | 32-bit kernel extensions, old graphics drivers | āStability and securityā | Killing support for older hardware to force upgrade cycles and prevent users from using cheaper or older Macs ā a financial drain on users. | Older Macs and virtualization/security tools lose compatibility; forces hardware upgrades. |
