So I have a relatively new 27" iMac (purchased around 2013-14). Haven't used it much because it's incredibly slow, which I attribute to the super slow hard drive (need to upgrade to a solid state). Unrelated to my current issue. Long story short, my kids are starting to use it frequently, so I decided to make them each an account and add restrictions based on each of them (time limits, what apps they can use, what web sites they can visit, etc). The problem is, it's completely useless. Doesn't work. At all. The MAIN issue is that I set the controls up, then log into each respective account to make sure it works, only to find out the settings I created aren't being saved. Nothing I do seems to work or make the settings stick. This must be a somewhat new bug, because I remember it working better in Yosemite. However, even when it did work, it was still pretty buggy. It was always blocking sites, even when I would always allow them, or allowing apps that I didn't approve, etc. OSX is updated as much as it can be (no updates showing through app store, so I'm assuming it's updated all the way). Anyone have any ideas? I initially bought this thing solely for the kids and it's sat near unused, partly because the parental controls have never worked great, and now they just don't work at all. Are there any alternatives to use , or should I try to figure this out? I may just wipe the whole computer and start from scratch to fix this, but it's a total Deja Vu with my old Windows machines.
