Blue­tooth blues

Mac Format - - GENIUS TIPS - by Larry Robin­son

QThanks for bring­ing to light cur­rent prob­lems with El Cap­i­tan and Blue­tooth. My prob­lems started when I up­graded my 2010 iMac to El Cap­i­tan, and I’m con­cerned that when I re­place it later this year, I won’t only have prob­lems with wire­less pe­riph­er­als, but with Blue­tooth net­work­ing too. Should I in­sist on see­ing it work­ing be­fore I buy?

AThere’s no ev­i­dence that cur­rent Mac mod­els have un­der­ly­ing prob­lems in their Blue­tooth hard­ware, which con­sists of well proven chips and, as you’ve found, can work prop­erly for both pe­riph­er­als and net­work­ing in older ver­sions of OS X.

These is­sues are far more likely the re­sult of ker­nel or driver bugs. In nor­mal use, the lat­est iMacs seem fairly re­li­able, and dropouts are in­fre­quent, mak­ing their use with wire­less pe­riph­er­als largely trou­ble-free. Net­work­ing may be a lit­tle more prone to prob­lems, but those should only be an oc­ca­sional ir­ri­tant.

There’s no way for users to al­le­vi­ate or fix these is­sues: they await re­vi­sions to the driv­ers in El Cap­i­tan or, if not there, in Sierra. Al­ways keep a wired mouse and key­board to hand to help with en­ter­ing Ap­ple Hard­ware Test or Di­ag­nos­tics at startup when needed. Ap­ple sup­plies USB ca­bles with its lat­est wire­less de­vices for charg­ing them as wired USB de­vices, although their pur­pose isn’t to work around Blue­tooth prob­lems like this.

Hope­fully Blue­tooth prob­lems will be fixed, both with up­dates to El Cap­i­tan and in the macOS Sierra up­grade.
