SardusX86 Posted October 10, 2018 Share Posted October 10, 2018 Hi All, I would like to replace macOS Sierra with macOS Mojave in a Sierra / High Sierra multiboot system in the same ssd (Asus P5G41T-M LX mb - Intel Core2Duo E8600 cpu - legacy-bios mode with Clover bootloader). Unfortunately both existing partitions are HFS + and I read that installing MacOS Mojave requires an APFS partition. Is it possible to format/convert, for example, the existing macOS Sierra partition from HFS+ to APFS without deleting the other existing macOS High Sierra partition? Thanks in advance for Your help Link to comment Share on other sites More sharing options...
pjg61 Posted October 14, 2018 Share Posted October 14, 2018 Mojave does not require APFS. APFS is only installed by default if you have an SSD drive. My experience is that if you format your disk to HFS+ before install, the Mojave installer will leave it as such during the install. Link to comment Share on other sites More sharing options...
