Very extensive fixes, and changed re-installation options in Recovery mode. 1.94 GB, again a very substantial update. 584 MB, with many bug and security fixes. Some Macs became quite unstable, suffering freezes or kernel panics, which didn’t resolve until upgraded to High Sierra. It also introduced a serious bug in DAS/CTS scheduling which leads to backup failure. For many this replaced El Capitan’s freezing problems with kernel slowdowns. A 4.77 GB download, followed by a long and complex installation. Much of the urgency and additional fixes have been in response to a series of glaringly obvious security vulnerabilities, in particular the root user gaffe. So in the first just over three months, we have had three major updates. A much smaller update, mostly with Safari 11.0.2 to mitigate the risk of Spectre. At 2 GB, another major update with many bug and security fixes. This was an additional fix to the last fix. This was an urgent fix to address the notorious root user vulnerability, and was just over 1 MB. Again, at 2.1 GB it was also catching up with things which should have been fixed before 10.13 was released. This also addressed some important security matters, including the KRACK Wi-Fi vulnerabilities. But at 915 MB, it contained more extensive fixes which had missed the original release date. The primary reason for this was to address a glaring encryption password bug in Disk Utility, and a bug allowing malicious apps to extract keychain passwords. There were inevitably some APFS conversion issues, and a few users were quickly begging to go back to Sierra, but most fared well. An initial two-step installer was hurriedly replaced with monolithic, 5.17 GB. As Apple doesn’t let us look at its bug reporting databases, I’ll step through their update records. With all the supplemental updates and kludges to High Sierra, as it approaches the mid-term update to 10.13.3, I am going to step back and compare its life-history with those of Sierra and El Capitan before, to try to get a more objective and less emotive assessment of how it is doing. The police get younger, time passes more quickly, and each major release of macOS is more of a disaster.
