So it is best to have a suitable (smaller) SSD under APFS with a bootable clone of the system that is regularly created via CCC or similar (although you can exclude "work data folders" and the like from the CCC start clone in order to keep it compact keep) and additionally a normal TM-BackUp on another external HFS+ disk, especially for all data that is not "start-relevant". for a MacOs other version) there is actually nothing to prevent a conventional partition, especially since from Mojave an APFS volume is required as a start volume anyway.īut what will then no longer work from Mojave onwards is that a smaller partition of an external HFS + backup disk is equipped with a bootable clone of the startup volume and a larger partition is used for the TM backup, because the Mac then no longer even starts should start from the clone. If, however, currently (only) backing up a TM backup on an (external) APFS disk can be the problem, then formatting the internal disk with APFS - and thus also creating another (virtual) APFS volume there (e.g.
If I understand the linked post correctly, the problem is apparently more that a Time Machine BackUp TO an APFS-formatted disk can currently cause problems and less because it is from an HFS + -formatted (external) disk to an internal (possibly. Resolving an APFS volume is currently only possible via the terminal Partition can be changed again in the disk utility Installation of older Mac OS as well as Windows, Linux or similar possible
More background knowledge and planning required Individual allocation of file system and formatting / partition table In the following I have compiled an overview for you. If not only Mojave is to be installed next to Catalina or perhaps High Sierra, but a completely different system, then the partition is preferable to the volume. Advantages and disadvantages of Mac hard drive partitionsĮven if it is a little more complex, there are - if necessary and desired by the user - more options for using the specially allocated hard disk space. How much storage space do the system, apps and files require? How much should you leave free for the other partitions? All of this flows into the preparatory work. However, you have to know about the properties of the systems, the formatting and the required memory. Partitioning a hard drive is ideal for experienced users if they want to use a different file system and a different or older operating system on the newly created partition. Hard disk partition for more individual use Optimized for use with SSD memories and hard drivesĬan cause problems with Time Machine backups Only from 10.13 High Sierra for Fusion Drives or HDD hard drives Not suitable for Windows, Linux or others
Not suitable for macOS 10.12.6 Sierra or older
