New ker­nel ex­ten­sions

Mac|Life - - FEATURE -

Af­ter up­grad­ing to High Sierra, you’ll need to grant spe­cific ap­proval for new third­party ex­ten­sions you in­stall. Ex­am­ples are Log­itech Op­tions and In­tego VirusBar­rier. You’ll see an alert say­ing “Sys­tem Ex­ten­sion Blocked” that prompts you to go to Sys­tem Pref­er­ences > Se­cu­rity & Pri­vacy.

There, a note will say “Sys­tem soft­ware from de­vel­oper [Name] was blocked from load­ing.” Click Al­low only when you know that an ac­tion on your part has caused this to be listed. All that de­vel­oper’s ex­ten­sions within the same app can then run. Ex­ten­sions in­stalled be­fore you up­graded don’t re­quire reap­proval.
