Ask HN: Mojave, anything developers should know about before upgrading?

19 pointsdrcongo12 comments

From what I've seen around the web, this upgrade seems less problematic than previous years, but has anyone spotted any gotchas that other developers could do with knowing about before upgrading?

Very brave - I tend to wait until at least the first point release (so, 10.14.1) or later before taking the plunge. I'd run brew doctor afterwards for sure...

VirualBox does not work: https://www.virtualbox.org/ticket/17805

tl;dr: Mojave blocks the VBoxDrv.kext <5.3 kernel extension from loading because "it will panic the machine if allowed to load", and it's up to Oracle to patch on version >=5.3 (current latest is 5.2.18)

Systems that depend on VirtualBox such as Vagrant don't work either.

Some guy has posted a workaround but it involves disabling the SIP, proceed at your own risk: https://silvae86.github.io/sysadmin/mojave/beta/vagrant/virt...

Downloading it so.. I hope not but Apple updates tend to cause problems rather than solving them, also upgrading Fedora at the same time which may turn out to be dumb, fingers crossed.

Dark mode is overrated, looks bad compared to what's available on GNOME but nothing blew up so far.

We (The republic of Hipsters) declare everything dark mode as our default settings.

I upgraded last night and almost can't tell the difference, which I guess is a good thing.

Had to reinstall Xcode command line tools after the upgrade finished.

So far no issues for me upgrading. Just missing dark mode for Chrome.

I did run `brew doctor && brew prune`

Your fonts will look like shit if you use an external display. Luckily there's a workaround:

defaults -currentHost write -globalDomain AppleFontSmoothing -int 3

defaults write -g CGFontRenderingFontSmoothingDisabled -bool false

Presumably this is because the vast majority of external displays are not high DPI?

Thank you for this! My Thunderbolt displays looked like garbage this morning, and I suddenly regretted upgrading to Mojave until I found this.

No gotchas, but I recommend that you do a full backup before upgrading.

Works great for me. I’m pretty surprised.
