Determine Volume Groups in macOS Catalina, Big Sur and later

由 空扰寡人 提交于 2020-12-06 12:32:49
问题 Since macOS 10.15 (Catalina), a volume, as the user sees it, may actually be comprised of multiple volumes, such as the System and the Data volume. I'm writing a tool that needs to identify these volumes separately because when using specific file operations, such as searchfs and fts_read , which do not cross such volume boundaries, I need to understand which volumes belong together, so that, when the user wants to search a system volume, I know to include both the "System" and its "Data"

如何使用Mojave将APFS卷上的MacOS Catalina Beta安装到双引导

如果你想与macOS Mojave或macOS High Sierra一起运行MacOS Catalina Beta，你可以通过向Mac添加一个新的APFS卷来实现这一点，如果该Macs硬盘被格式化为APFS。这有效地为MacOS Catalina 10.15和Mojave 10.14.x（或High Sierra）创建了双启动方案，并提供了一种在Mac上作为主要操作系统简单安装MacOS Catalina Beta的替代方法。这种方法有一些优点，特别是你可以使用一台Mac来运行两个操作系统，而且你不需要为Catalina指定存储容量，因为它将与其他MacOS版本共享驱动器空间并扩展如所须。 https://www.macdown.com 重要说明：这仅适用于高级Mac用户。有关运行MacOS Catalina以及其他macOS版本的问题的报道不一，特别是对于具有T2安全芯片和Touch ID的Mac。在尝试此操作之前，请确保您拥有数据和Mac的完整备份。 要开始使用，您需要完整备份Mac和计算机上的所有数据，与MacOS Catalina兼容的Mac，您需要注册MacOS Catalina beta测试计划，并且您需要至少提供35GB的可用磁盘空间虽然更多，但尝试使用Catalina可获得最佳效果。 如何在MacOS Mojave / High

问题 usually creating RAM disks works with the following commands hdid -nomount ram://<blocksize> Returns e.g. /dev/disk2 Then I would format the disk, with say newfs_hfs /dev/disk2 followed by mounting it: mount -t hfs /dev/disk2 /some/mount/target This procedure doesn't seem to work with APFS. I'm on High Sierra beta 9. The mount command doesn't output any error, but the path is not mounted. In my case, after the hdid command finished, newfs_apfs -i /dev/disk2 yields nx_kernel_mount:1364:
