Ask HN: Disk Encryption for Mac OS X

3 pointsby brianjking11 yıl önce3 comments

Hello,

I have a Mid-2014 13" Retina MacBook Pro 2.6GHz Intel Core i5 with 8gb memory + SSD hard drive running 10.10.3 Yosemite.

I was using FileVault 2 included in OS X by default for full disk encryption, however, the performance was absolutely abysmal. Does anyone have any alternative suggestions or suggestions on how to make FileVault actually a reasonable option?

kernel_task was consuming 80-150% of cpu power on a regular basis and was simply slamming my otherwise rather powerful machine.

Thanks!

I would take that to an apple store. I have a mid-2012 retina Macbook Pro at home with full disk encryption turned on, and I never see anything remotely close to that kind of usage.

FileVault is completely transparent for me here. I can hardly notice any performance hit.

Now, if only Apple can fix the incessant graphics freezing...

I have an almost identical configuration with full disk encryption turned on and I haven't experienced this issue.
