Speed-up macOS Mojave boot time
29 September 2018, 03:43
Some people have been reporting slow boot times after upgrading to macOS Mojave.
Here are some steps to try and alleviate this issue—please do try all of these in the sequence given, and don’t cherry pick ones that seem easiest. My guess is that you’ve ended-up here after trying other basic solutions such as pruning your account’s startup apps list:
- Reset the SMC.
- Reset the NVRAM/PRAM.
- Reboot to safe mode, and then reboot again to see if the problem has been fixed.
- Run the Maintenance app (although (a) be careful because this is a powerful app that can delete data if used wrongly and (b) at the time of writing (Sept 2018) it isn’t yet available for Mojave, although will be soon.)
- Try uninstalling software that utilises kernel modules. This might sound complicated but typical examples include antimalware apps/virus scanners, firewall apps, virtualisation software, screen sharing tools, and some NAS apps.
- Try examining and removing startup services using the excellent KnockKnock app.
