I put a third-party SSD in my Mac mini, and High SierraвЂ™s installer managed the conversion to APFS without complaint.

The conversion to APFS even happens if youвЂ™ve upgraded your Mac with some Solid State Drives (SSDs).

If youвЂ™re using a Mac equipped with all-flash storage вЂ“ a Retina MacBook Pro, for example, or a MacBook Air, MacBook, a 2013 or later MacBook, some Mac mini and iMac models вЂ“ the conversion to APFS will be automatic when you first install High Sierra. With the general release of High Sierra for the Mac, APFS has come to Macs too.ДЄuto-Conversion to APFS for Flash-Only Macs You wonвЂ™t notice anything visibly different, but the way in which your Mac stores files and interacts with its storage system are more efficient and better suited for the future than how itвЂ™s worked up until now.ДЄPFS was rolled out to iPhone and iPad users earlier this year with the release of iOS 10.3. ItвЂ™s also tremendously more efficient when it comes to copying files and folders вЂ“ youвЂ™ll see almost instant operations.ДЄPFS is very much an вЂњunder the hoodвЂќ change. APFS employs advanced data integrity features to make sure your data is safe. Now devices across AppleвЂ™s product like rely on flash storage вЂ“ writing data to silicon instead of to the surface of a spinning disk.ДЄpple needed to future-proof its core file system technology, and needed to adapt it to the changing needs of flash storage. Floppy disks are a historical relic, and hard drives are headed that way too.

When HFS Plus was introduced floppy disks and spinning hard drives were the way most devices stored data. WhatвЂ™s more, thereвЂ™s been a sea change in how storage works. Now devices in your pocket can hold 128 GB or more. At the time HFS was first introduced, a 20 MB hard drive was astonishingly big. Times change, and so does technology вЂ“ rapidly.В Storage needs have increased exponentiallyВ HFS debuted in 1985. So the Mac вЂ“ and by extension, the iPhone, iPad, iPod touch and other Apple devices вЂ“ used a file system that was 30 years old. HFS Plus was introduced in 1998, updating an earlier file system (plain old HFS) that had already been around for 13 years. The file system Apple has used on its device up until recently was called HFS Plus.

Read on for the full story.ДЄll computing devices rely on a file system to control how your device stores and retrieves data. File systems arenвЂ™t a sexy feature or even a visible one, but the last time the MacвЂ™s file system changed, Bill Clinton was president. ThereвЂ™s a hitch if youвЂ™re using a Mac with a hard drive, including Macs with Fusion Drives. One of the key features of High Sierra is a new file system.

Thank you for everyone's time reading this, I know it was kind of a long one.Apple has released High Sierra, a new upgrade to macOS thatвЂ™s installable on most Macs built since 20. TL DR So, I guess my question ends up being: does anyone know why I can't partition a drive that is in APFS format? And why does Time Machine use JHFS+ format if the new native format is APFS? As far as the first question, is it just me or maybe because High Sierra is in Beta and it's just something that hasn't been fixed? And for the second, also maybe because it's in Beta and it's just something that hasn't been updated? What I learned after setting up Time Machine, is that it actually needs to be in the JHFS+ format to work. From there I was able to partition it off and reformat one volume to APFS for Time Machine and use the other for extra storage. So, being the hard-head I am, I went into terminal and used the 'diskutil eraseDisk' option to reformat it to JHFS+, which worked. In the drop-down for the Erase menu, I was only given the four APFS options as the format.

Down below where they normally display the errors it only said that 'This volume cannot be resized.' I did also run into the issue where I thought that I would just reformat it back to Mac OS Extended (Journaled) (AKA: JHFS+). However, once it was in the APFS format and in the partition drop-down, everything was grayed out from the plus/minus buttons to the resize text box. So, I naturally thought I would reformat the drive as APFS and then partition it so everything is in the same format as my internal hard drive.

I have a 4TB WD MyPassport for Mac and I was planning on partitioning it so I could have half of it to use as a Time Machine and the other half for storage. I have impatiently updated my Mac to the High Sierra Public Beta and I noticed something strange when I was trying to mess with my external hard drive.
