OS X quick-fire ques­tions

Mac Format - - GENIUS TIPS -

Can I re­vert back to run­ning OS X El Cap­i­tan 10.11.3?

Yes, although it is com­plex to say the least, and ex­poses your Mac to se­cu­rity risks. You’d need to in­stall El Cap­i­tan from scratch, and then up­date it us­ing the Combo in­staller for 10.11.3 be­fore man­u­ally restor­ing your apps, doc­u­ments, and so on, from your Time Ma­chine backup. Some cur­rent ver­sions of apps might not work even then.

Why can’t my iMac sleep with­out also sleep­ing its disk?

Although the En­ergy Saver pane of­fers the abil­ity to pre­vent hard disks from sleep­ing dur­ing sys­tem sleep, this does not work in some re­cent mod­els of iMac. If you don’t want your disks put to sleep, those mod­els will also then not let the sys­tem go to sleep ei­ther.

How can I put win­dows into the Dock in slo-mo?

This was a favourite trick of Steve Jobs when demon­strat­ing OS X. When you click on the am­ber Min­imise but­ton at the top-left cor­ner of a win­dow, hold ß; the win­dow will min­imise into the Dock over a pe­riod of five sec­onds.

Can OS X block in­ter­net track­ing?

In Sys­tem Pref­er­ences, the Se­cu­rity & Pri­vacy pane’s Pri­vacy tab has a Lo­ca­tion Ser­vices item, where you can pre­vent apps de­ter­min­ing your lo­ca­tion, but to stop browser-based track­ing look in your browser’s pref­er­ences. Sa­fari has an ex­cel­lent ex­ten­sion for this in Bet­ter (free, Mac App Store).
