About Zaphu
A service journal, not a gadget feed
Zaphu covers everyday consumer technology the way a service manual does: the symptom first, then the steps, in plain language you can follow at the desk where the machine sits.
It is written for Mac owners, Linux tinkerers and phone-and-app troubleshooters who would rather repair a setup than replace it.
