Yosemite has brought Sa­fari to its knees

Mac Format - - APPLE TALK -

Dur­ing a day of us­ing Yosemite, the spin­ning wheel of sleep has ap­peared more fre­quently than in 10 months of Mav­er­icks. I’ve cleared the cache. I’ve deleted the Cache.db file (~/Li­brary/ Caches/com.ap­ple.Sa­fari/Cache.db). I’ve quit and re­launched Sa­fari. I’ve added no ex­ten­sions. My down­load speed is al­ways greater than 50Mbps. Ron Hughes Delet­ing the cache files is a good first step, although you also need to re­boot af­ter­wards and empty the Trash for it to take full ef­fect. I haven’t ex­pe­ri­enced this Sa­fari slow­down on any my Yosemite Macs, but I’ve seen a lot of re­ports that im­pli­cate con­nected cloud ser­vices like Drop­Box and iDrive. Dis­con­nect­ing and then re­con­nect­ing them has fixed the is­sue for some peo­ple.

Other sug­ges­tions – in­clud­ing re­set­ting the Sys­tem Man­age­ment Con­troller and the non-volatile RAM – seem sus­pect. The NVRAM stores dis­play res­o­lu­tion, speaker vol­ume and other set­tings for di­rectly at­tached hard­ware, not de­vices ac­cessed over the in­ter­net. Like­wise, I’m scep­ti­cal that sig­nif­i­cant mem­ory leaks or other bugs have made it past Ap­ple’s QA process. So my money is on con­nected cloud drives.
