Apple Releases macOS High Sierra 10.13.2 Supplemental Update With Spectre Fix

Other than slower to install than the progress bar would have one to believe, my MacBook Pro (Touch Bar) is operating fine. Again install was slow on Mac Pro (2013), rebooted and ran fine. But the next time I rebooted it stuck at 99.99% for several hours before I aborted. Safe mode did not boot. Visual/verbose mode never reached the final command prompt. Passed Diagnostic mode so I reinstalled OS and got the machine working again. 10.13.2 without the supplement. Which I am not going to install again for another couple weeks.
I ran four different kinds of benchmark software, both before and after this update, and there was no loss of performance on my 2014 MBP SSD. In fact, it was slightly higher.
Tell that to the Safari Team.

Thanks for posting the results, just upgraded a mid 2015 Pro from Yosemite to High Sierra, everything running great, appears to run faster but now I need to install the Supplemental update, I'm hoping this final one won't have any negative surprises but according to what I read it is more about Safari, so perhaps the first security update was more involved.
The only warning, I use Keychain without Icloud, the local items folder deleted all of my passwords when I migrated from one Pro to a new one, this time I copied/pasted every password to a new section as insurance.
Sure enough Apple never fixed this issue, all of the passwords in my Local Items section gone, if I did not copy them, over 200 passwords and multiple secure notes would have been lost, poorly produced by Apple.
Using a browser is probably the easiest way to exploit Spectre.

@GordonGekko999 Yes, Apple sprung the first update to address the flaws rather surreptitiously. I wish I had done a benchmark at some point before 10.13.2 to know the absolute effect. Subjectively speaking, I haven't noticed any significant impact on performance. But large file transfers always seem like they take forever anyway, so I'm less likely to notice a few seconds of difference.
Thanks for your reply. I was trying to install it from the App Store on my MacBook, and I also tried downloading it directly from Apple's website. Now I see that Mac OS 10.13.3 and iTunes 12.7.3 are available as a combo update, I will try to install that.
I just tried the latest update and I have the same result, the computer restarts and appears to install the update, welcome screen, analytics prompt, but then I get the message "some updates failed to install, install them now?" and I'm still at 10.13.1 Repeating the installation process leads to the same result.
Weird , that test in ghacks says safari on 10.2is not vulnerable. Unsure why, I do have purify ad blocker. As an extra precaution I had disabled JavaScript, although I enabled it for the test.
