Four months after the release of macOS High Sierra, it still hasn&rsquo;t published the necessary information, and while without seeing the details it&rsquo;s hard to speculate on how much work it would be to support APFS in our utilities, it&rsquo;s a good bet that it&rsquo;s more than six months&rsquo; work. In the meantime, in spite of the messages we&rsquo;ve put on our website, customers continue to purchase the products, realise they don&rsquo;t work for them, then ask for refunds (or, worse, file chargebacks through their respective banks); this actually <em>costs<\/em> us money, and also results in a string of less than satisfied customers. We don&rsquo;t want that, and you, our customers, don&rsquo;t want that either.<\/p>\n<p>There have also been changes in recent versions of the macOS to tighten up security, which is definitely a good thing for end users, but makes it very awkward to make utility software function in a reasonable manner.<\/p>\n<\/blockquote>\n\n<p>This is a shame because HFS+ fragmentation will likely be with us <a href=\"https:\/\/mjtsai.com\/blog\/2017\/11\/15\/dive-into-apfs\/\">on spinning disks<\/a> for a long time. I&rsquo;m also not convinced that APFS fragmentation is a non-issue on SSDs. APFS apparently includes <a href=\"https:\/\/blog.macsales.com\/43210-tech-101-do-mac-hard-disk-drives-need-to-be-defragged\">automatic defragmentation<\/a>, but there&rsquo;s little information about when and how that works. Does it do anything for large files when the disk is nearly full (as APFS volumes often will be due to <a href=\"https:\/\/mjtsai.com\/blog\/2017\/11\/13\/local-time-machine-uses-apfs-snapshots\/\">snapshots<\/a>)? My <a href=\"https:\/\/mjtsai.com\/blog\/2018\/02\/19\/lightroom-classic-cc-7-2\/\">brand new<\/a> Lightroom database is already fragmented into 10,833 pieces. Does that overhead really not matter? This is for a 1.5 GB file that&rsquo;s stored on an SSD with (according to Finder) 363 GB available.<\/p>\n\n<p>See also: <a href=\"https:\/\/alastairs-place.net\/blog\/2018\/02\/21\/aura\/\">Aura<\/a> (<a href=\"https:\/\/news.ycombinator.com\/item?id=16444375\">Hacker News<\/a>).<\/p>\n\n<p>Previously: <a href=\"https:\/\/mjtsai.com\/blog\/2017\/09\/15\/superduper-and-apfs\/\">SuperDuper and APFS<\/a>.<\/p>","protected":false},"excerpt":{"rendered":"<p>Alastair Houghton: Apple, for whatever reason, elected to release its new filesystem &mdash; and convert existing machines over to using it &mdash; without first publishing the filesystem specification so that utility vendors like us could update our software.
