    APFS for fusion

    yes, yes it is coming I hear and yes I hope to win the lottery some day Has anyone heard anything about when or even if Apple is going to have the APFS for the Fusion Drive owners? I am beginning to think that they can't get it to work.

    Convert to APFS

    I wish to reformat my HDDs (2x 1 TB WD) from the OS Extended (Journaled) format to the new APFS, and to make a stripped RAID with these disks. One of these disks is currently my boot drive. The machine is the Mac Pro 5,1 Tower (not a flashed 4,1), running High Sierra. Blackmagic shows that I...

    Cloning APFS to HFS+

    What are folks using to clone an APFS boot disk to HFS+? CarbonCopy Cloner 5 and 4 appear to refuse to copy system data due to lack of attribute mapping.

    APFS + TRIM slows down some SSDs

    Let's try make a report here with make and models of the SSDs affected by boot and r/w slow downs. I have a 256Gb 840 EVO. HS w/ supplemental update and trim enabled takes 47 seconds from chime to desktop (auto login). I will add the time later with TRIM disabled. Macmini late 2014 2.6Ghz.

    Question - a laptop and an iMac, APFS and HFS+, iCloud

    I hope someone here may be able to answer this. I am using a MacBook (2016) and an iMac (2015). Of course the MacBook has a solid state drive, and would be converted to APFS on upgrading to High Sierra. That machine hasn't been upgraded yet. The iMac has a fusion drive, and remains HFS+...

    APFS not compatible with OWC SSDs

    Argh. I tried installing the public beta a few weeks ago and got a weird message about firmware verification failure and that I couldn't install it. I figured it would be fixed with the real release today. Nope! APFS doesn't play with some 3rd-party SSDs - apparently including my OWC 6G...

    Just wondering about APFS...

    So, I have a Mid-2015 27"iMac that came with a 1Tb Fusion drive. I've replaced the HDD for a 960Gb Sandisk SSD. As Apple SSD is super fast, I kept it. As you know, this iMac has a 24Gb SSD. It's too small to almost anything, so I decided to "fusion" it with the new SSD, by following the DIY...

    Updating to High Sierra tips

    I have a 2017 SSD iMac and normally when I update to a new OS on past macs I have left the external time machine drive plugged in. Is it worth this year making a time machine back up, then turning time machine off, and ejecting the drive? Is it best with the APFS update to just have the iMac...

    APFS High Sierra Boot?

    Has anybody tried to boot off APFS under High Sierra on a 5,1? Based on beta 4 release notes, only mid 2012 will be officially supported in a future beta.
