苹果放出 macOS Catalina 正式版更新后，因为改动较大，所以不兼容的应用还是蛮多的，不过好在大部分是旧版本问题不兼容，apps更新到最新后应该可以解决绝对部分。
值得注意的macOS Catalina 10.15不再支持32位应用，仅支持64位应用，这也意味着将有一大批旧应用不能在新系统中运行。
一名 iOS开发者在macOS Catalina的/ Library / Apple / Library / Bundles
/中找到了名为IncompatibleAppsList.bundle的捆绑包，其中包含了多达235种与Catalina不兼容的应用程序。这份列表的主要用途是在用户安装
Catalina 过程中提醒其不兼容新系统的已安装应用程序。列表中包含一些较为常用的应用程序：
Transmit 4.1.7
1Password 2.12.2
iStats Menu 2.9
Box Sync 4.0

SugarSync 1.0

VMWare Fusion 3.1.4
