Thanks, Slarti, & it's good to hear it's not just me & that El Cap just plain sucks. My Air is mid-2012 & the Mini is around the same age. As I mentioned, I've always updated to the next OS once the version hit x.2 or x.3 - & that's what I did with the Mini but it was so awful, I held off on the Air. I hope Sierra really is good (famous last words, but it can't be much worse than El Cap) - I'll update the Mini first to see how it is before biting the bullet on my Air.Slartibartfast wrote:I updated my 2010 MacBook Pro to El Cap (from Snow Leopard, I believe) and have been squirrelly too. also. A friend (who is a software developer and a Mac person) said that Sierra was good and recommended that I upgrade before High Sierra came out. I don't know how old your machine is, but my coal-fired version is a bit long in the tooth and the next update could be the one that doesn't support my machine. You always want to have the most up-to-date version possible when then one that leaves you behind comes out. I'll be switching from El Cap to Sierra sometime in August and I would recommend doing it yourself before High Sierra comes out.
And in case anyone else runs into the problem my husband & brother did (older iphones, no security updates available), it's because only iphone 5 & up, 4th gen ipads & up, & ipod touch 6 & up have the bad wifi chips in them. Older devices don't. Old stuff FTW!
